Tuna Safety Tips for Grocery Store Managers

Safe Storage & Temperature Control for Fresh Tuna

Fresh tuna must be stored at 41°F (5°C) or below, with frozen tuna maintained at 0°F (-18°C) or lower. Use separate, dedicated refrigeration units for seafood to prevent temperature fluctuations that accelerate histamine buildup—a naturally occurring compound that causes Scombroid poisoning if tuna is stored improperly. Implement FIFO (First In, First Out) inventory rotation and monitor refrigerator temperatures daily with calibrated thermometers; non-functioning equipment is a leading cause of seafood-related illness outbreaks. Raw, thawed tuna should be used within 24–48 hours; canned tuna has a longer shelf life but should still be stored in a cool, dry location away from direct sunlight.

Cooking Temperatures & Preparation Protocols

The FDA Food Code requires tuna be cooked to an internal temperature of 145°F (63°C) for 15 seconds when served hot. Use calibrated meat thermometers to verify doneness; color alone is not a reliable indicator of food safety. For sushi-grade or raw preparations, source tuna from suppliers certified to freeze it at -4°F (-20°C) for 7 days or -31°F (-35°C) for 15 hours to kill parasites—a critical step that must be documented. Train deli and prepared-foods staff to wear separate gloves and use dedicated cutting boards for tuna to prevent cross-contact with allergens and pathogens; seafood cross-contamination is a frequent violation during health inspections.

Cross-Contamination Prevention & Staff Training

Designate separate utensils, cutting boards, and storage shelves for tuna and other seafood, keeping them isolated from raw poultry and beef to prevent bacterial transfer. All staff handling tuna must undergo food safety certification (ServSafe or equivalent) and understand proper handwashing, including scrubbing for 20 seconds with soap and warm water before and after handling raw seafood. Establish a cleaning schedule for refrigeration units, ice machines, and display cases—biofilm buildup in ice machines is a common vector for Listeria contamination. Document temperature logs, supplier certifications, and staff training records; the FDA and local health departments rely on these records during compliance inspections.
