Tuna Storage Guide for Food Trucks: FDA Standards & Best Practices

FDA Temperature Requirements & Shelf Life

The FDA Food Code mandates that all tuna—whether raw, cooked, or in salads—must be stored at 41°F (5°C) or below to prevent bacterial growth and histamine accumulation. Raw tuna has a shelf life of 1–2 days when stored properly; cooked tuna lasts 3–4 days; and tuna salad with mayonnaise lasts 3–5 days depending on preparation date and ingredient freshness. Time-temperature abuse (especially during transport to your food truck) is the leading cause of spoilage. Use calibrated refrigeration thermometers daily and document readings in your food safety log to prove compliance during health inspections.

Proper Storage Containers, Labeling & Organization

Store tuna in food-grade, sealed containers with air-tight lids to prevent cross-contamination and odor transfer to other foods. Label every container with the product name, date received, and date opened using a waterproof marker or label maker. The FDA requires that prepared tuna products display a "use by" date based on preparation time. Organize your walk-in cooler or reach-in unit with tuna on lower shelves, away from ready-to-eat foods like salads and desserts. Use NSF-certified storage containers only; never use repurposed food packaging or non-food containers.

FIFO Rotation & Common Storage Mistakes

First-In, First-Out (FIFO) rotation is essential: place newer tuna behind older stock so older product is used first. Many food truck operators fail to rotate stock, leading to waste and increased contamination risk. Common mistakes include storing tuna above ready-to-eat foods (risk of drips), exceeding shelf-life windows to save money, and ignoring temperature fluctuations during service. Never leave tuna at room temperature for more than 2 hours, or 1 hour if ambient temperature exceeds 90°F. Implement a written inventory system and conduct weekly audits to catch expired products before they reach customers. Document all storage activities as evidence of your food safety program for regulators.
