Tuna Safety Guide for San Diego Consumers & Restaurants

San Diego Health Code Requirements for Tuna Handling

San Diego County Department of Environmental Health enforces California Code Title 3, which mandates strict temperature controls for raw and cooked tuna. Tuna must be stored at 41°F or below, and frozen tuna intended for raw consumption (sushi-grade) must be frozen at -4°F for 7 days or -31°F for 15 hours to eliminate parasites. Restaurants must maintain detailed temperature logs and conduct regular equipment inspections. Violating these standards can result in health citations, temporary closure, or criminal liability under California Health and Safety Code §113952.

Common Tuna Contamination Risks & Pathogens

Scombrotoxin (histamine) is the most common tuna-related hazard, forming when bacteria break down amino acids in improperly chilled fish. Symptoms include flushing, headache, and gastrointestinal distress—often mistaken for allergic reactions. Listeria monocytogenes and Vibrio species can also contaminate tuna, especially in undercooked or raw preparations. The FDA and CDC track these pathogens through CORE (Coordinated Outbreak Response & Evaluation) and issue recalls through FoodSafety.gov. Cross-contamination during prep—using the same cutting boards for raw tuna and ready-to-eat foods—is a primary restaurant violation.
