AAFCO

Association of American Feed Control Officials — sets model regulations for pet food labeling and ingredients adopted by most US states.

AAFCO Ingredient Definition

Official name and description for ingredients used in pet food, as defined in the AAFCO Official Publication.

Acidified Food

A low-acid food (pH above 4.6) to which acid or acid ingredients are added to achieve a final pH of 4.6 or below. Examples include pickled vegetables and some salsas. Some states require special training to sell acidified foods under cottage food laws.

Aflatoxin

A carcinogenic toxin produced by Aspergillus molds that can grow on nuts, grains, and dried fruits stored in warm, humid conditions. Proper storage at low humidity and visual inspection help prevent contamination in cottage food products.

Allergen

A substance that triggers an immune response in sensitive individuals. The FDA recognizes 9 major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. All must be declared on labels.

Allergen Declaration

A required statement on food labels identifying the presence of any of the Big 9 allergens. You can declare allergens using a 'Contains:' statement after the ingredient list (for example, 'Contains: Wheat, Milk, Eggs') or by using parenthetical notation within the ingredient list itself (for example, 'flour (wheat), butter (milk)'). If you use a Contains statement, it must list all major allergens — you cannot split them between methods.

Barcode/UPC

A Universal Product Code — the scannable barcode on retail products that identifies the manufacturer and specific product. UPC barcodes are generally not needed for cottage food sold at farmers markets, but they become essential if you move into retail stores or online marketplaces. You can purchase a UPC barcode through GS1 US starting at about $250 for a single barcode or through resellers for $5 to $30 each.

Batch Costing

Calculating the total cost to produce one batch of a product, then dividing by the number of units to determine per-unit cost. Include all ingredients, packaging, labels, and a labor allocation. Essential for accurate pricing.

Batch Size

The quantity of product made in a single production run. Optimizing batch size balances efficiency with freshness. A common approach is to make enough for one market day plus a small buffer, scaling up only after confirming demand.

Batch Tracking

The practice of assigning a unique identifier to each production run so that every unit of product can be traced back to specific ingredients, production dates, and conditions. If a customer reports an issue, batch tracking lets you identify exactly which products may be affected. A simple batch code system uses the production date plus a sequence number — for example, '240315-01' for the first batch made on March 15, 2024.

Best-By Date

A date printed on food packaging indicating when the product is expected to be at peak quality. Unlike expiration dates on perishable foods, best-by dates are about quality, not safety — shelf-stable cottage food products are generally safe past this date but may decline in taste or texture. Set best-by dates conservatively: if your cookies stay fresh for 3 weeks, label them with a 2-week best-by date.

Big 9 Allergens

The nine major food allergens that must be declared on all US food labels under FALCPA and the FASTER Act: milk, eggs, fish, crustacean shellfish, tree nuts (specific type must be named), peanuts, wheat, soybeans, and sesame. These nine allergens account for approximately 90% of all food allergic reactions. Declaration is required even in trace amounts, and using the 'Contains:' statement format is recommended for clarity.

Bloom (Chocolate)

A whitish coating on chocolate caused by fat migration (fat bloom) or sugar crystallization (sugar bloom). While not harmful, bloom indicates improper tempering or storage. Store chocolate at 60–70°F with less than 50% humidity to prevent it.

Botulism

A rare but potentially fatal illness caused by Clostridium botulinum toxin. The spores thrive in low-oxygen, low-acid environments — making improperly canned foods the primary risk. Proper acidification (pH below 4.6) and pressure canning prevent it.

Brand Identity

The visual and emotional elements that distinguish your food business — including logo, color palette, packaging style, and brand voice. Consistent branding builds recognition and justifies premium pricing. Start with a logo, consistent labels, and a cohesive social media presence.

Break-Even Point

The sales volume at which your total revenue equals your total costs — the point where you stop losing money and start making profit. Calculate it by dividing your fixed costs (booth fees, insurance, permits) by your profit per unit (selling price minus cost per unit). For example, if your monthly fixed costs are $200 and your profit per cookie bag is $4, you need to sell 50 bags per month to break even.

Brix

A measurement of sugar concentration in a solution, expressed as degrees Brix (°Bx). One degree Brix equals 1 gram of sucrose per 100 grams of solution. Jams typically require 65°Bx for proper gel set. Measured with a refractometer.

Bundle Pricing

Offering multiple products together at a discount compared to individual prices. Gift baskets, variety packs, and holiday boxes increase average order value. A $30 gift basket containing $36 worth of individual items is perceived as great value.

CFR (Code of Federal Regulations)

The codification of all rules published by federal agencies. Title 21 CFR covers food and drugs, including labeling requirements (21 CFR Part 101), food additives, and good manufacturing practices that apply to all food producers including cottage food operators.

Citric Acid

A natural acid derived from citrus fruits, used to lower pH in candies, preserve color in dried fruits, and adjust acidity in jams. Available as a white crystalline powder. A common acidulant for reaching the 4.6 pH threshold in acidified foods.

COGS (Cost of Goods Sold)

The total direct cost of producing the goods you sold during a period, including ingredients, packaging materials, and labels. COGS does not include overhead like booth fees, mileage, or insurance. Knowing your COGS per unit is the foundation of profitable pricing. Track COGS monthly to identify cost increases early — ingredient prices for staples like butter, eggs, and flour can fluctuate 20% to 30% year over year.

Commercial Feed License

State license required to manufacture or distribute pet food, issued by the state Department of Agriculture.

Commercial Kitchen

A food preparation facility that has been inspected and licensed by a local health department, meeting code requirements for commercial-grade equipment, ventilation, plumbing, and sanitation. Operating from a commercial kitchen allows you to sell products beyond cottage food restrictions, pursue wholesale accounts, and ship across state lines. Building your own costs $30,000 to $150,000+.

Consignment

A sales arrangement where you place your products in a retail store but retain ownership until the product sells. The store takes a percentage (typically 20% to 40%) of each sale. If the product does not sell, it is returned to you. Consignment can be a low-risk way to get shelf space in local stores, but check your state's cottage food law — some states do not allow consignment because it is considered indirect sales.

Co-packing

Short for contract packing — hiring a third-party manufacturer to produce your recipe in their facility using your specifications and branding. Co-packers handle production so you can focus on sales and marketing. Minimum order quantities typically range from 100 to 5,000 units. Best suited for products with simple, scalable recipes like granola, sauces, spice blends, and candies.

Co-Packing

Hiring a licensed commercial kitchen or food manufacturer to produce your recipes at scale. A step between cottage food and full manufacturing. Co-packers handle production, often packaging, and ensure compliance. Minimum runs typically start at 100–500 units.

Cottage Food Amendment

A legislative update that modifies an existing cottage food law, often expanding allowed products, raising revenue caps, or permitting online sales. These amendments are introduced regularly; operators should monitor their state legislature for changes.

Cottage Food Business Plan

A document outlining your products, target market, pricing strategy, startup costs, and growth projections. Even a simple one-page plan helps clarify your approach and is required by some banks for business accounts.

Cottage Food Disclaimer

A required label statement informing consumers that the product was made in a home kitchen that has not been inspected by the health department. Most states mandate specific wording — for example, 'Made in a home kitchen that is not subject to state licensing or inspection.' Always use your state's exact required language, as paraphrasing can result in a violation.

Cottage Food Label Design

The visual presentation of your product packaging. Effective labels use clear fonts, attractive colors, and professional layout. Budget options include Canva templates ($0) and Avery labels ($15–30). Professional designers charge $50–200 per label design.

Cottage Food Law

A state-level statute that allows individuals to produce and sell certain low-risk food products from a home kitchen without a commercial food license. Every US state now has some version of a cottage food law, though rules on allowed products, revenue caps, and sales channels vary widely. Cottage food laws are designed as a low-barrier entry point for food entrepreneurs.

Cottage Food Operation (CFO)

A home-based food business exempt from commercial kitchen and food establishment licensing requirements. CFOs typically sell shelf-stable, non-potentially hazardous foods directly to consumers. Rules vary significantly by state.

Cottage Food Permit

A permit or registration issued by a state or county agency that authorizes a home kitchen to produce and sell cottage food products. Not all states require a permit — some only require registration or self-certification. Permit fees typically range from $0 to $75 per year. In California, cottage food operations register as Class A (direct sales) or Class B (direct and indirect sales).

Cottage Food Permit Fee

The cost to register or obtain a cottage food permit, ranging from free to $250 depending on the state. Some states like California charge $0 for Class A registration, while others like Michigan charge a small annual fee.

Cottage Food Registration

A lightweight enrollment process required in some states before selling cottage food. Unlike a permit, registration is typically free or low-cost, self-certified, and does not involve inspections. Examples include California's Class A registration.

Cottage Food Training Requirement

A mandate in some states that cottage food operators complete a food safety course before selling. May be a general food handler course, a state-specific online module, or an accredited program like ServSafe. Some states accept any ANSI-accredited certificate.

Cottage Industry

A small-scale, home-based manufacturing or production business. The term originated from 17th-century English weavers who worked from their cottages. In the food context, it refers to food businesses operating from residential kitchens under cottage food laws.

Country of Origin

A labeling requirement for certain food products indicating where they were produced, grown, or processed. For cottage food, this primarily applies if you use imported ingredients that are the sole or primary component of your product — for example, imported honey or imported chocolate. The FDA requires country of origin labeling for specific commodities, and some states have additional requirements.

Critical Control Point (CCP)

A step in food production where control can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level. Examples include cooking to a specific temperature or acidifying to a target pH.

Cross-Contamination

The transfer of harmful bacteria or allergens from one food, surface, or utensil to another. Prevented by using separate cutting boards for raw and ready-to-eat foods, frequent handwashing, and proper sanitization.

Crude Protein

Measure of total protein content in pet food, reported as a minimum percentage on the guaranteed analysis panel.

CSA (Community Supported Agriculture)

A model where consumers purchase a subscription or 'share' from a local farm or food producer, typically receiving a weekly box of products throughout a growing season. Some cottage food producers participate in CSA programs by adding baked goods, jams, or other value-added products to farm CSA boxes. This provides predictable recurring revenue and guaranteed sales before production begins.

Customer Retention

Strategies to keep existing customers coming back. Repeat customers spend 67% more than new ones. Tactics include punch cards (buy 10, get 1 free), exclusive flavors for regulars, pre-order texting lists, and consistent quality.

FALCPA (Food Allergen Labeling and Consumer Protection Act)

A 2004 federal law requiring food labels to clearly identify any of the major food allergens. Applies to all packaged food in the US, including cottage food products. Sesame was added as the 9th major allergen via the FASTER Act of 2021.

Farmers Market

A recurring marketplace — typically weekly and often outdoors — where local farmers, bakers, and food producers sell directly to consumers. Farmers markets are the most common and effective sales channel for cottage food businesses, offering built-in foot traffic, sampling opportunities, and face-to-face relationship building. Booth fees range from $25 to $100 per day depending on location and market size.

Farmers Market Booth Fee

The cost to rent a selling space at a farmers market, typically $20–75 per market day or $200–800 for a season. Some markets also take a percentage of sales (5–10%). Factor this into pricing to maintain profitability.

Farm-to-Table

A food philosophy and marketing concept emphasizing locally sourced ingredients with a short supply chain from farm to consumer. Cottage food producers can leverage the farm-to-table trend by sourcing ingredients from local farms, highlighting those partnerships on labels and social media, and selling at farmers markets alongside the farmers who supply them. This narrative justifies premium pricing and resonates with health-conscious, environmentally aware consumers.

FDA

The Food and Drug Administration, a federal agency that regulates food labeling, safety standards, and food facility registration in the United States. While cottage food operations are primarily regulated at the state level, FDA allergen labeling (FALCPA) and ingredient listing standards are widely considered best practice, and many states incorporate these federal requirements into their cottage food laws.

FDA (Food and Drug Administration)

The federal agency responsible for protecting public health by ensuring the safety of food, drugs, and cosmetics. While cottage food is regulated primarily at the state level, FDA labeling and allergen rules still apply to all food sold in the United States.

Feed Control Official

State regulatory official responsible for enforcing commercial feed laws and reviewing pet food product registrations.

Fermentation

A metabolic process where microorganisms convert sugars into acids, gases, or alcohol. Used in bread (yeast), pickles (lacto-fermentation), kombucha, and sourdough. Some states allow fermented foods under cottage food laws; others specifically prohibit them.

Foodborne Illness

Sickness caused by consuming contaminated food or beverages. The CDC estimates 48 million Americans get foodborne illnesses annually. Proper food handling, temperature control, and hygiene are the primary prevention methods.

Food Establishment Permit

A license issued by a local health department authorizing a business to prepare and sell food from an inspected commercial kitchen. This is the permit you graduate to when you outgrow cottage food. It requires passing a health inspection, operating from a licensed kitchen, and typically holding a food manager certification like ServSafe Manager.

Food Freedom Law

State legislation broadly deregulating home food production, often removing permits, inspections, and revenue caps for direct-to-consumer sales. Wyoming passed the first food freedom act in 2015; over a dozen states now have similar laws.

Food Grade Packaging

Packaging materials that are safe for direct contact with food and will not leach harmful chemicals or contaminants. All bags, boxes, jars, and wraps that touch your cottage food products must be food-grade. Look for 'food safe' or 'FDA compliant' markings when purchasing. Common food-grade materials include LDPE plastic bags, borosilicate glass jars, kraft paper with food-safe coatings, and wax paper.

Food Handler Card

A certification proving completion of an accredited food safety course, typically covering safe temperatures, handwashing, allergen awareness, and pest control. Required in some states; usually costs $10–25 and takes 2–4 hours online.

Food Handler's Permit

A credential issued after completing a food safety training course, typically available online for $10 to $25. About half of US states require cottage food producers to hold a valid food handler's permit before they can legally sell. The course covers safe food handling, cross-contamination prevention, personal hygiene, and temperature control. Most permits are valid for 2 to 5 years.

Food Recall

The removal of a food product from the market because it may be unsafe due to contamination, mislabeling, or undeclared allergens. Even cottage food producers can face recalls — the most common trigger is undeclared allergens on labels. Maintain detailed batch records and customer contact information so you can quickly notify buyers and remove affected products if a safety issue arises.

Food Safety Modernization Act (FSMA)

A landmark 2011 federal law that shifted the focus of food regulation from responding to contamination to preventing it. FSMA applies to commercial food facilities and generally does not apply to cottage food operations. However, if you scale to commercial production or begin selling across state lines, FSMA requirements — including preventive controls, hazard analysis, and supply chain verification — become relevant.

FSMA

Food Safety Modernization Act — federal law requiring preventive controls for food manufacturing, including animal food under 21 CFR Part 507.

Gel Point

The temperature (220°F at sea level) at which a jam or jelly mixture has enough sugar concentration and pectin activation to set into a gel upon cooling. Tested with the sheeting test (dripping from a spoon) or a candy thermometer.

General Liability

Insurance coverage for bodily injury, property damage, and personal injury claims that arise from your business operations — such as a customer tripping over your farmers market booth setup or an allergic reaction from a sample. General liability policies for cottage food businesses typically provide $1 million to $2 million in coverage and cost $300 to $1,500 per year. Many farmers markets and retail venues require proof of general liability insurance.

General Liability Insurance

Broad insurance coverage protecting against third-party claims of bodily injury or property damage. Covers incidents at your booth (customer trips on your table) as well as product-related claims. Typically $300–600/year for cottage food operations.

Gluten-Free Claim

A regulated labeling claim defined by the FDA as food containing less than 20 parts per million (ppm) of gluten. If you label a product as gluten-free, you must be able to verify that it meets this threshold — which may require testing ($100 to $200 per sample). Use dedicated equipment for gluten-free products and produce them before any wheat-containing items to prevent cross-contact. The gluten-free market continues to grow and can command significant price premiums.

GMP

Good Manufacturing Practices — the baseline sanitation and production standards for food manufacturing, codified in FDA's Title 21 CFR Part 117. GMPs cover personal hygiene, facility cleanliness, equipment maintenance, and pest control. While cottage food operations are typically exempt from formal GMP requirements, following these practices protects your customers, reduces liability, and prepares you for eventual commercial licensing.

Good Manufacturing Practices (GMP)

FDA regulations (21 CFR Part 110/117) establishing minimum sanitation and processing requirements for food production. While cottage food operators may be exempt from inspections, following GMP principles — such as clean surfaces, proper handwashing, and pest control — is strongly recommended.

Gross Margin

The percentage of revenue remaining after subtracting the cost of goods sold (COGS). Calculated as (Revenue - COGS) / Revenue x 100. Healthy cottage food businesses typically aim for gross margins of 60–75%.

Guaranteed Analysis

Required nutritional panel on pet food labels showing minimum crude protein, minimum crude fat, maximum crude fiber, and maximum moisture.

HACCP

Hazard Analysis and Critical Control Points — a systematic approach to food safety that identifies biological, chemical, and physical hazards in the production process and establishes controls to prevent them. While full HACCP plans are typically required only for commercial food operations, understanding HACCP principles helps cottage food producers identify and manage risks in their home kitchens.

HACCP (Hazard Analysis Critical Control Points)

A systematic food safety management approach that identifies physical, chemical, and biological hazards and establishes critical control points to prevent them. While not typically required for cottage food, understanding HACCP principles improves safety practices.

Handcrafted

A marketing term implying that products are made by hand with personal attention and care, as opposed to factory automation. Accurate and effective for cottage food producers who genuinely prepare products manually. Pair it with specific details — 'handcrafted in our Austin kitchen' or 'hand-rolled and cut' — to add credibility. Avoid the term if you use primarily automated equipment, as misleading claims can damage trust.

Headspace

The air gap between the food surface and the jar lid in canned goods. Proper headspace (typically 1/4 inch for jams, 1/2 inch for fruits) allows for expansion during processing and creates a proper vacuum seal. Too much or too little causes seal failure.

Health Department Inspection

An official visit by a local or state health inspector to evaluate food safety practices, sanitation, and regulatory compliance. Most cottage food laws exempt home kitchens from routine inspections, though some states allow inspections upon complaint.

High-Acid Food

A food with a natural pH of 4.6 or below, such as most fruits, jams, and fruit butters. High-acid foods are generally safer for home canning using water bath methods because their acidity inhibits Clostridium botulinum growth.

Home Kitchen Deduction

A tax deduction for the portion of home expenses (rent/mortgage, utilities, insurance) attributable to your cottage food business. Calculated based on the square footage of kitchen space used exclusively for production divided by total home square footage.

Home Kitchen Disclaimer

A label statement required by most states informing consumers that the product was prepared in a home kitchen not subject to government food safety inspection. Exact wording is prescribed by each state and must appear prominently on the label.

Home Occupation Permit

A local government permit that authorizes a business to operate from a residential property. Some cities and counties require this permit for any home-based business, including cottage food operations. Requirements may include limits on signage, customer traffic, and hours of operation. Check with your local planning or zoning department before starting.

Hot Fill Method

A preservation technique where food is heated to at least 185°F and poured into containers while hot, then sealed immediately. The heat and vacuum seal provide preservation without additional processing. Used for high-acid sauces and syrups.

Labeling Compliance

The requirement that all packaged food labels meet federal (FDA/FALCPA) and state-specific standards. For cottage food, compliance means including the product name, ingredient list in descending order by weight, allergen declaration, net weight, your business name and address, and the state-required home kitchen disclaimer. Non-compliant labels can result in fines, permit revocation, or forced product recalls.

Labeling Requirements

The set of mandatory information that must appear on cottage food product packaging. Typically includes product name, ingredients in descending order, allergen declaration, net weight, producer name and address, production date, and the state-required home kitchen disclaimer.

Liability Insurance

Insurance that protects your business from financial loss if someone is injured or suffers property damage as a result of your products or business activities. For cottage food businesses, the two main types are general liability (covers injuries at your booth or premises) and product liability (covers claims from your food products). Policies start at around $200 to $500 per year through providers like FLIP (Food Liability Insurance Program).

Listeria monocytogenes

A bacterium that can grow at refrigerator temperatures and cause listeriosis, a serious infection. It thrives in soft cheeses, deli meats, and unpasteurized dairy — products generally prohibited under cottage food laws.

LLC

A Limited Liability Company is a business structure that separates your personal assets from your business liabilities. If someone sues your cottage food business, an LLC generally protects your home, car, and savings from being seized. Filing fees range from $40 to $500 depending on your state. Many cottage food producers start as sole proprietors and consider forming an LLC as their business grows and liability exposure increases.

LLC (Limited Liability Company)

A business structure that provides personal liability protection while maintaining tax simplicity. Many cottage food operators form single-member LLCs to protect personal assets from potential product liability claims. Formation costs $50–500 depending on the state.

Loss Leader

A product priced at or below cost to attract customers who will then purchase more profitable items. A cottage food example: selling $3 cookies at a market to draw traffic to your booth, where customers also buy $12 jam gift sets.

Lot Number

A code assigned to a specific batch or production run of a food product. Lot numbers enable traceability — if a safety issue is discovered, you can identify and recall only the affected lot rather than your entire inventory. Many states require lot numbers or production dates on cottage food labels. A simple format like 'LOT-2024-0315A' is sufficient.

Natural Claim

A food labeling term that the FDA considers to mean 'nothing artificial or synthetic has been added that would not normally be expected in the food.' Unlike 'organic,' the term 'natural' has no formal FDA certification process. You can generally use it if your product contains no artificial flavors, colors, or preservatives. However, the FTC monitors misleading claims, so use it honestly and be prepared to explain what makes your product natural.

Net Profit

The actual profit remaining after subtracting all expenses — ingredients, packaging, market fees, insurance, mileage, and other overhead — from total revenue. Net profit margin for successful cottage food businesses typically ranges from 25–45%.

Net Quantity

The amount of food in a package, expressed by weight for solid products (ounces, grams) or by volume for liquid products (fluid ounces, milliliters). Net quantity must appear on the Principal Display Panel and must reflect the food only — not the weight of the packaging. For items sold by count (a dozen cookies), most states still require net weight to be stated.

Net Weight

The weight of the food product only, excluding packaging. Federal law requires net weight on the Principal Display Panel in both US customary and metric units — for example, 'Net Wt. 8 oz (227g).' Use a calibrated digital kitchen scale accurate to at least 0.1 oz. Consistent underweight is a federal violation, so weigh each package and slightly overfill rather than underfill.

Non-GMO

A voluntary labeling claim indicating that a product does not contain genetically modified organisms. Unlike 'organic,' there is no federal certification requirement for non-GMO claims, though the Non-GMO Project offers a third-party verification program. Using non-GMO ingredients can command a price premium at farmers markets, but be careful making claims you cannot substantiate — the FTC can take action against misleading marketing.

Non-Potentially Hazardous Food

Foods that do not support rapid growth of infectious or toxigenic microorganisms. They do not require refrigeration and have water activity below 0.85 or pH below 4.6. Most cottage food laws restrict sales to these items.

Nutritional Adequacy Statement

Label claim indicating whether a pet food is 'complete and balanced' for a specific life stage or intended for 'intermittent or supplemental feeding only.'

Nutrition Facts Panel

The standardized nutritional information box found on packaged food products showing calories, fats, carbohydrates, protein, and other nutrients per serving. Most cottage food producers are exempt from providing a Nutrition Facts panel if they have fewer than 100 employees and make no nutritional claims. However, if you make any claim — such as 'low sugar,' 'high protein,' or 'good source of fiber' — you must provide a lab-verified Nutrition Facts panel, which costs $200 to $500 per product.

Pathogen

A microorganism — such as bacteria, virus, or parasite — capable of causing foodborne illness. Common food pathogens include Salmonella, E. coli O157:H7, Listeria monocytogenes, and Clostridium botulinum.

Pectin

A natural gelling agent found in fruits that causes jams and jellies to set. Commercial pectin (Sure-Jell, Pomona's) provides consistent results. Regular pectin requires high sugar; low-methoxyl pectin allows reduced-sugar recipes using calcium activation.

pH

A scale from 0 to 14 measuring acidity or alkalinity. Foods below 4.6 pH are considered high-acid and inhibit growth of Clostridium botulinum. Critical for determining whether jams, pickles, and sauces qualify as cottage food.

pH Level

A measure of acidity/alkalinity on a scale of 0-14. Foods with pH below 4.6 are considered acidic enough to inhibit bacterial growth. Critical for jams, pickles, and fermented foods.

pH Testing

The process of measuring the acidity or alkalinity of a food product on a scale from 0 (most acidic) to 14 (most alkaline). Foods with pH below 4.6 are considered high-acid and resist the growth of Clostridium botulinum, the bacterium that causes botulism. pH testing is essential for jams, pickles, sauces, and any canned product. Affordable pH meters cost $15 to $50; pH test strips are less accurate but cost under $10.

PLU Code

Price Look-Up code — a 4- or 5-digit number used primarily for bulk produce at grocery store checkouts. PLU codes are assigned by the International Federation for Produce Standards (IFPS) and are different from UPC barcodes. Cottage food producers rarely need PLU codes unless selling unpackaged produce items at retail. For packaged cottage food, a UPC barcode is the appropriate identifier.

Pop-Up Shop

A temporary retail space set up at events, festivals, or shared locations. Lower commitment than a regular farmers market booth. Popular options include holiday bazaars, church events, school fundraisers, and brewery collaborations.

Potentially Hazardous Food (PHF/TCS)

Foods that require time and temperature control for safety because they support rapid growth of dangerous bacteria. Examples include dairy products, meat, cut fruits, cooked rice, and custard-filled pastries. Most cottage food laws prohibit the sale of PHF/TCS foods because home kitchens lack the equipment to maintain safe temperatures consistently.

Pressure Canning

A preservation method using pressurized steam to reach 240°F (116°C), the temperature required to destroy Clostridium botulinum spores in low-acid foods. Required for vegetables, meats, and soups. Many cottage food laws prohibit pressure-canned products.

Principal Display Panel

The part of a food package label most likely to be seen by consumers at the point of purchase — typically the front of the package. The Principal Display Panel (PDP) must include the product name (statement of identity) and the net quantity of contents. The net weight must appear in the lower 30% of the PDP. This is where your brand, product name, and key selling points should be featured.

Production Date

The date a food product was manufactured or prepared. Some states require a production date on cottage food labels, while others accept a best-by date instead. Including the production date helps customers gauge freshness and helps you manage inventory rotation. Format consistently across all products — 'Made on: 03/15/2024' or 'Produced: March 15, 2024.'

Production Log

A record of each batch produced, including date, recipe, batch size, ingredient lots, cooking times and temperatures, and any deviations. Production logs demonstrate due diligence, help with traceability in case of complaints, and are required by some states.

Product Liability

Legal responsibility for harm caused by a product you manufactured or sold. If a customer has an allergic reaction because you failed to declare an allergen, or gets sick from your food, product liability law may hold you financially responsible for medical bills, lost wages, and damages. Product liability insurance (typically $300 to $800 per year) protects against these claims. An LLC also provides a layer of personal asset protection.

Product Liability Insurance

Insurance covering claims of illness or injury caused by your food products. Typically $250–500/year for cottage food businesses. Not usually required by law but strongly recommended. Many farmers markets require proof of coverage.

Prohibited Items

Foods that cannot be sold under a state's cottage food law, typically including meat, dairy, canned low-acid vegetables, and any foods requiring refrigeration. Selling prohibited items can result in fines, cease-and-desist orders, or criminal charges.

Proofing (Bread)

The final rise of shaped bread dough before baking, during which yeast ferments and produces CO2. Proper proofing temperature is 75–80°F for 45–90 minutes. Over-proofed dough collapses; under-proofed yields dense bread. The poke test checks readiness.

Sales Tax

A consumption tax collected by the seller and remitted to the state. Rules for cottage food vary: some states exempt food from sales tax, others exempt only cottage food, and some require collection. Always check your state and local requirements.

Sales Tax Permit

A state-issued permit allowing a business to collect and remit sales tax on taxable transactions. Many states exempt cottage food products from sales tax entirely, while others require collection. Even in exempt states, you may need a permit for record-keeping purposes. Check your state's Department of Revenue for cottage food-specific guidance before your first sale.

Sales Venue Restriction

A limitation on where cottage food products may be sold. Common restrictions include farmers markets only, home delivery only, or no commercial retail. Some states allow roadside stands and community events but prohibit consignment in stores.

Salmonella

A group of bacteria causing salmonellosis, one of the most common foodborne illnesses. Often associated with raw eggs, poultry, and unpasteurized milk. Bakers should use pasteurized eggs in no-bake products.

Sampling Regulations

State rules governing whether cottage food producers can offer free samples of their products at farmers markets and events. Some states allow sampling freely, others require handwashing stations and sneeze guards, and a few prohibit it entirely.

Sanitizer

A chemical agent that reduces microorganisms on food-contact surfaces to safe levels. Common options include diluted bleach (1 tablespoon per gallon of water), quaternary ammonium compounds, and iodine solutions.

Scale (Kitchen)

A measuring device for weighing ingredients and finished products. A digital kitchen scale accurate to 0.1 grams ($15–30) ensures recipe consistency. A separate scale for net weight labeling should be calibrated and accurate to 0.5 grams.

Schedule C

IRS form used by sole proprietors to report business income and expenses. Most cottage food operators file Schedule C with their personal Form 1040. Allows deduction of ingredients, packaging, market fees, mileage, and home kitchen expenses.

Seasonal Products

Products aligned with holidays, seasons, or local events. Pumpkin spice in fall, peppermint bark at Christmas, berry jams in summer. Seasonal items create urgency and repeat visits. Plan your seasonal calendar 2–3 months in advance.

Seasonal Revenue Planning

Forecasting income fluctuations throughout the year. Cottage food sales often peak during holidays (Thanksgiving, Christmas, Valentine's Day) and farmers market season (May–October), with slower periods in winter months.

ServSafe

A nationally recognized food safety certification program administered by the National Restaurant Association. The ServSafe Food Handler certificate is the most widely accepted credential and satisfies most state cottage food training requirements.

Shared Kitchen

A licensed commercial kitchen that rents production time to multiple food businesses on an hourly, daily, or monthly basis. Also called commissary kitchens or kitchen incubators. Hourly rates typically range from $15 to $35. Shared kitchens are the most popular stepping stone from cottage food to commercial production because they avoid the massive capital investment of building your own facility.

Shelf Life

The length of time a food product remains safe and at acceptable quality. Determined by water activity, pH, packaging, and storage conditions. Common cottage food shelf lives: cookies (2–4 weeks), bread (3–5 days), jams (12–18 months), candy (3–6 months).

Shelf Stable

Foods that can be safely stored at room temperature in sealed containers without refrigeration. Achieved through low water activity, low pH, high sugar content, or preservatives. The cornerstone of cottage food eligibility.

Shelf-Stable

A food product that can be safely stored at room temperature without refrigeration for an extended period. Shelf stability is determined by low water activity (below 0.85), low pH (below 4.6), or both. Most cottage food laws restrict producers to shelf-stable items because they pose minimal food safety risk when stored and transported without refrigeration.

Small Batch

A marketing descriptor indicating that products are made in limited quantities rather than mass-produced. Like 'artisan,' there is no regulated definition, but it conveys quality, freshness, and exclusivity to customers. Small batch production is a natural advantage for cottage food producers — lean into it in your branding. Phrases like 'made in small batches of 24' or 'limited weekly availability' create perceived scarcity that supports premium pricing.

Social Media Marketing

Using platforms like Instagram, Facebook, and TikTok to promote products and engage customers. Food businesses benefit from visual content — post process photos, behind-the-scenes videos, and customer testimonials. Instagram and TikTok drive the most cottage food sales.

Sole Proprietorship

The simplest business structure where the owner and business are legally the same entity. Most cottage food businesses start as sole proprietorships. No formation paperwork required, but provides no personal liability protection.

Sourdough Starter

A live culture of wild yeast and lactic acid bacteria maintained by regular feeding with flour and water. Creates the characteristic tang and leavening in sourdough bread. A well-maintained starter can be kept indefinitely and shared with customers as an add-on product.

State Department of Agriculture

The state agency that oversees agricultural operations, food safety programs, and often cottage food regulations. In some states, the Department of Agriculture is the primary regulator of cottage food operations, while in others that role falls to the Department of Health. Your state's Dept. of Ag website is usually the best place to find current cottage food rules.

Sugar-Free Claim

A regulated FDA claim meaning the product contains less than 0.5 grams of sugar per serving. Making this claim on your label triggers the requirement for a full, lab-verified Nutrition Facts panel. If you want to indicate reduced sugar without triggering this requirement, use language like 'no added sugar' or 'sweetened with honey' instead — but even these phrasing choices have specific FDA definitions. When in doubt, describe your product's qualities without using regulated terms.
