Food Safety Basics for Home Kitchen Producers
Master the fundamentals of safe food handling: temperature control, cross-contamination prevention, handwashing, and pest control.
Why Food Safety Matters for Cottage Food
Even though cottage food products are typically non-potentially-hazardous (meaning they do not require refrigeration), food safety is still critical. Contamination can occur through improper handling, unsanitary conditions, allergen cross-contact, or pest exposure. A single foodborne illness incident can result in legal liability, loss of your cottage food permit, and harm to your customers.
Many states require cottage food producers to complete a food handler's safety course. Even if your state does not require it, the knowledge is invaluable. The FDA estimates that 48 million Americans get sick from foodborne illnesses each year.
The Temperature Danger Zone
The temperature danger zone is the range between 40 degrees F (4 degrees C) and 140 degrees F (60 degrees C). Within this range, bacteria can double in number every 20 minutes. The FDA's Food Code establishes these critical temperature guidelines:
Cold foods must be held at 40 degrees F or below
Hot foods must be held at 140 degrees F or above
Food should not remain in the danger zone for more than 2 hours (or 1 hour if the ambient temperature is above 90 degrees F)
When cooling cooked foods, cool from 140 degrees F to 70 degrees F within 2 hours, and from 70 degrees F to 40 degrees F within an additional 4 hours
For cottage food producers, this is most relevant when:
Cooling baked goods before packaging
Transporting products to farmers markets (especially in summer)
Storing ingredients like eggs and butter before use

Allergen Requirements: The 9 Major Allergens & FALCPA
Federal law requires disclosure of the 9 major food allergens. Learn FALCPA and FASTER Act rules, labeling formats, and cross-contact prevention.
Why Allergen Labeling Is Critical
Food allergies affect an estimated 32 million Americans, including 5.6 million children under age 18, according to FARE (Food Allergy Research & Education). Severe allergic reactions (anaphylaxis) can be fatal — approximately 200 Americans die each year from food-induced anaphylaxis.
As a cottage food producer, you are legally required to disclose allergens in your products. This is not just a best practice — it is federal law.
The 9 Major Allergens
The Food Allergen Labeling and Consumer Protection Act (FALCPA) of 2004 originally identified 8 major allergens. The FASTER Act (Food Allergy Safety, Treatment, Education, and Research Act), signed into law on April 23, 2021, added sesame as the 9th major allergen effective January 1, 2023.
The 9 major allergens are:
Milk — includes all dairy: butter, cream, cheese, whey, casein, lactose
Eggs — includes whole eggs, egg whites, egg yolks, and egg-derived ingredients like albumin and lysozyme
Fish — includes bass, flounder, cod, and all other fin fish species (must declare the specific species)

Cross-Contamination Prevention
Cross-contamination occurs when harmful bacteria, allergens, or other contaminants are transferred from one food, surface, or person to another. The four main types are:
Food-to-food: Raw eggs dripping onto finished cookies, or tree nut residue transferring to a nut-free product
Equipment-to-food: Using the same cutting board for raw ingredients and finished products without washing
People-to-food: Coughing, sneezing, or touching your face and then handling food
Environment-to-food: Pets, pests, household chemicals, or dust contaminating food products
Prevention strategies:
Use separate, color-coded cutting boards and utensils for different product types
Wash all equipment with hot, soapy water (at least 170 degrees F) between batches
Sanitize countertops with a food-safe sanitizer (1 tablespoon unscented liquid chlorine bleach per gallon of water)
Never prepare cottage food when you are ill — particularly with vomiting, diarrhea, or diagnosed infections like Salmonella, E. coli, Hepatitis A, or Norovirus
Keep pets completely out of the kitchen during production
Store all finished products in sealed, food-grade containers
Handwashing: The Most Important Safety Practice
The CDC identifies handwashing as the single most effective way to prevent the spread of foodborne illness. Proper handwashing technique:
Wet hands with clean, warm running water (at least 100 degrees F)
Apply soap and lather all surfaces — backs of hands, between fingers, under nails
Scrub for at least 20 seconds
Rinse thoroughly under running water
Dry with a clean, single-use paper towel or clean cloth towel
When to wash hands:
Before starting food preparation
After touching raw ingredients (especially eggs)
After using the restroom
After touching your face, hair, or body
After sneezing, coughing, or blowing your nose
After handling trash or cleaning supplies
After touching pets or animals
After handling money
Between handling different allergen-containing products
Ingredient Storage
Proper storage prevents spoilage, pest contamination, and cross-contact:
Dry goods (flour, sugar, spices): Store in airtight containers at room temperature (60-70 degrees F), away from direct sunlight. Label with purchase date. Flour is good for 6-8 months; whole wheat flour for 3 months.
Eggs: Refrigerate at 40 degrees F or below. Use within 3-5 weeks of purchase. Never use cracked eggs.
Butter and oils: Butter refrigerated for up to 1 month, or frozen for up to 4 months. Oils stored in cool, dark place; most are good for 6-12 months after opening.
Nuts: Refrigerate or freeze for extended storage. Oils in nuts can go rancid at room temperature within a few months.
Chocolate: Store at 60-70 degrees F. Avoid humidity. White "bloom" on chocolate is cosmetic, not a safety issue.
Always practice FIFO (First In, First Out) — use older ingredients before newer ones.
Pest Control
Your home kitchen must be free of pests during production. Common pest issues and solutions:
Ants: Seal all entry points with caulk. Store all ingredients in sealed containers. Clean up crumbs and spills immediately.
Cockroaches: Fix any water leaks. Eliminate moisture. Use gel baits in non-food-contact areas. Never spray insecticide near food or food preparation surfaces.
Mice/rats: Seal gaps larger than 1/4 inch. Store all ingredients in hard-sided containers (mice can chew through plastic bags). Use snap traps in non-production areas.
Pantry moths: Inspect all flour and grain products upon purchase. Store in sealed glass or heavy-duty plastic containers. Bay leaves placed in containers are a natural deterrent.
Flies: Keep kitchen screens in good repair. Never leave food uncovered. Use lidded trash cans and empty them daily during production.
Cleaning vs. Sanitizing
These are two different and equally important steps:
Cleaning removes visible dirt, food residue, and grease using soap and water
Sanitizing reduces bacteria to safe levels using a chemical solution or heat
The proper sequence for food contact surfaces is: scrape, wash, rinse, sanitize, air dry. Never towel-dry sanitized surfaces, as the towel can reintroduce bacteria.
For a food-safe bleach sanitizer: mix 1 tablespoon of unscented liquid chlorine bleach (5.25-8.25% sodium hypochlorite) per 1 gallon of water. This solution is effective for 24 hours, then must be remade.
Crustacean shellfish — crab, lobster, shrimp, crawfish (must declare the specific species)
Tree nuts — almonds, cashews, walnuts, pecans, pistachios, macadamia nuts, Brazil nuts, hazelnuts, chestnuts, and others (must declare the specific type)
Peanuts — a legume, not a tree nut, but one of the most common and severe allergens
Wheat — includes all wheat varieties: durum, semolina, spelt, kamut, einkorn, emmer
Option 2: "Contains" statement
Place a separate "Contains" statement immediately after or adjacent to the ingredient list.
Example: "Contains: Wheat, Milk, Eggs, Tree Nuts (Almonds)"
You may use both methods together, but if you use a "Contains" statement, it must list all major allergens present in the product — you cannot list only some allergens in the "Contains" line and others parenthetically.
Common Allergen Pitfalls for Cottage Food Producers
"May contain" statements are voluntary. FALCPA does not require or regulate advisory statements like "May contain traces of peanuts" or "Produced in a facility that processes tree nuts." However, many cottage food producers include them as a precaution when cross-contact is possible.
Spelt is wheat. If your recipe uses spelt flour, you must declare wheat as an allergen.
Soy lecithin is soy. Even though it contains very low levels of soy protein, it must be declared.
Natural flavors can contain allergens. If a natural flavor contains a major allergen, you must declare it.
Coconut is classified as a tree nut by the FDA for labeling purposes, even though it is botanically a fruit.
Highly refined soybean oil and peanut oil are exempt from FALCPA labeling (the refining process removes the allergenic proteins), but cold-pressed or expeller-pressed versions must be declared.
Cross-Contact Prevention
Cross-contact occurs when an allergen is unintentionally transferred to a food that does not normally contain it. In a home kitchen, this is a significant risk:
Shared equipment: If you bake peanut butter cookies and then sugar cookies using the same mixer and baking sheets, there is a risk of peanut cross-contact. Thorough washing between batches is essential.
Airborne particles: Flour dust (wheat allergen) can travel and settle on other products. Nut particles can become airborne during grinding.
Shared storage: Storing products with different allergen profiles in the same container or on the same shelf increases risk.
Best practices:
Produce allergen-free products first in the day, before any allergen-containing products
Use dedicated utensils and equipment for allergen-free products when possible
Wash all surfaces, equipment, and hands thoroughly between allergen-containing batches
Label all products clearly with allergen information
If cross-contact cannot be reliably prevented, include an advisory statement
State-Specific Allergen Rules
Some states have allergen requirements that go beyond federal FALCPA rules. For example:
Several states require the allergen disclosure to be prominently displayed (bold type or contrasting color)
Some states require allergen information to be provided verbally at farmers markets in addition to label disclosure
A few states require separate allergen warning signs at your booth or display
Check your state's specific cottage food law for any additional allergen disclosure requirements beyond the federal baseline.
