Onion Handling Violations in Louisville Restaurant Inspections

Temperature Control Failures with Cut Onions

Cut or diced onions are classified as potentially hazardous foods and must be held at 41°F or below per FDA Food Code standards that Louisville follows. Health inspectors find cut onions sitting in reach-in coolers without thermometer verification, or worse, left on prep tables during service without time-temperature documentation. When onions are cut in the morning and used throughout service, proper cooling time (typically 2 hours from 70°F to 41°F) is often skipped. Violations are cited under Kentucky Department for Public Health food service regulations, and repeated failures can result in corrective action plans or permit suspension.

Cross-Contamination and Prep Surface Issues

Louisville inspectors frequently identify cross-contamination violations when raw onions contact ready-to-eat foods or when the same cutting board is used for onions and proteins without washing between uses. Onions can harbor Salmonella and Listeria, which transfer easily to lettuce, tomatoes, and cooked dishes if surfaces aren't sanitized properly. Inspectors check for color-coded cutting boards (red for raw meat, yellow for vegetables) and proper three-compartment sink sanitization. Facilities that process both raw onions and ready-to-eat salads in the same station face particular scrutiny during Kentucky health code inspections.

Improper Bulk Onion Storage and Inventory Practices

Whole onions stored in warm, humid areas—such as above water lines, near heat sources, or in direct sunlight—violate Louisville storage standards and accelerate mold and bacterial growth. Inspectors examine onion bins for proper drainage, air circulation, and temperature conditions (ideally 45-50°F). Facilities without FIFO (First In, First Out) rotation systems show inspectors mixed batches of old and new onions, creating food waste and contamination risks. Louisville health department inspectors also document onions stored on floors, in damaged containers, or alongside chemicals, each violation carrying separate citations under Kentucky Administrative Regulations 902 KAR 45:045.
