Utah Cottage Food Storage and Sample Retention Requirements

Utah's cottage food storage rules go beyond "keep things clean." UDAF enforces specific requirements for where you store ingredients, how you handle finished products, and how long you must keep batch samples on hand. Missing any of these during an inspection can mean corrective actions or delayed approval.

The 14-Day Sample Retention Rule

Under UDAF Rule R70-560, every cottage food operator must retain a physical sample of each production batch for exactly 14 days. Each sample must be labeled with:

• The production date
• The production time
• The product name
• The batch identifier (if you use batch numbering)

The purpose is epidemiological tracing. If a consumer reports a foodborne illness, state health investigators need to test the specific batch that was sold. Without retained samples, there's nothing to test — and your operation becomes harder to defend.

Practical tips for managing sample retention:

• Dedicate a shelf or bin in your pantry specifically for retained samples (shelf-stable products don't need refrigeration for storage)
• Use a simple label system — masking tape with a marker works fine, as long as the date, time, and product name are legible
• Set a weekly reminder to discard samples that have passed the 14-day window
• Keep a batch log that matches each sample to its corresponding production record

Ingredient Storage Rules

UDAF inspectors check ingredient storage during pre-operational and follow-up inspections. The rules under R70-560 and R70-530 are straightforward but specific:

Location restrictions:

• All ingredients must be stored indoors
• At least six inches off the floor (use shelving or pallets)
• Never in bedrooms, bathrooms, or standard garages
• Exception: self-contained freezers may be kept in an enclosed garage, but the garage door must remain closed during storage

Temperature requirements:

• Commercial ingredients requiring refrigeration must be stored in a dedicated refrigerator maintained at 41°F or below
• Keep the dedicated refrigerator separate from household food to avoid cross-contamination

Separation:

• Business ingredients should be clearly separated from household groceries
• Raw materials should be stored below or away from finished products to prevent contamination
• Cleaning chemicals must be stored separately from food ingredients

Finished Product Storage

Finished cottage food products are shelf-stable by definition (if they weren't, they wouldn't be eligible under the program), so refrigeration isn't required. But you still need to store them properly:

• In a clean, dry area away from direct sunlight and heat sources
• Off the floor on shelving
• In food-safe packaging that protects against contamination
• Away from household chemicals, pet areas, and high-traffic zones

Products should be labeled and ready for sale, with all FDA-compliant label elements in place before they leave your kitchen.

Batch Record Keeping

Beyond the physical sample retention, UDAF requires you to maintain a written batch production log. Each entry should document:

• Recipe used (by name or reference number)
• Production date and time
• Batch volume or quantity produced
• All ingredients used (and sources, if required by your inspector)
• Where the batch was sold (farmers market name, store, direct sale)

These records serve the same traceability purpose as the physical samples. An inspector may request them during a follow-up visit, and they're essential for demonstrating compliance if there's ever a product complaint or illness report.

What Inspectors Look For

During a kitchen inspection, the storage-related items that UDAF inspectors specifically verify include:

• Food-contact surfaces are easily cleanable (no porous cutting boards, no exposed wood shelving in food prep areas)
• Ingredients stored at proper heights and temperatures
• No free-roaming pets in the home (this is a full-home rule, not just the kitchen)
• No concurrent domestic cooking during production hours
• Retained samples properly labeled and within the 14-day window
• Batch logs up to date and legible

Failing on storage-related items during an inspection doesn't usually mean an immediate shutdown, but it will trigger corrective action requirements and a follow-up inspection — which delays when you can start (or resume) selling.
