Shellfish Allergen Safety Guide for San Francisco

San Francisco's vibrant seafood industry requires strict shellfish allergen disclosure under California and federal law. Undeclared shellfish allergens remain among the top food recall triggers tracked by the FDA and CDC, posing serious risks to the 4 million Americans with shellfish allergies. Panko Alerts monitors 25+ government sources to help you stay informed about allergen recalls and safety requirements in real-time.

California Allergen Labeling & Disclosure Laws

California requires all packaged foods to clearly declare major allergens, including shellfish (crustaceans and mollusks), on ingredient labels under FDA guidelines. The California Department of Public Health (CDPH) enforces strict labeling standards that exceed federal minimums in some cases. Restaurant and retail establishments in San Francisco must also follow the California Health & Safety Code Section 113984, which mandates allergen menus or written documentation available upon request. Staff training on cross-contamination prevention is legally required in food service establishments.

San Francisco Health Department Local Requirements

The San Francisco Department of Public Health enforces the California Retail Food Code, requiring all food facilities—including seafood markets, sushi restaurants, and shellfish bars—to maintain allergen control procedures. Businesses must clearly identify shellfish items on menus, use separate equipment for allergen preparation, and maintain staff training records on allergen handling. The city conducts routine inspections and can issue violations for allergen mishandling or undisclosed cross-contact. Recent SFPD health department reports emphasize shellfish cross-contamination in shared preparation areas.

Recent Undeclared Shellfish Allergen Recalls

The FDA tracks undeclared shellfish in prepared foods, sauces, and international products monthly. In 2024-2025, multiple recalls involved shellfish allergens in Asian sauces, frozen appetizers, and pre-made salads distributed in California. The CDC coordinates with state health departments on investigation of allergic reactions linked to mislabeled products. Panko Alerts monitors these recalls in real-time across FDA, FSIS, CDC, and local San Francisco sources—critical for restaurants, retailers, and consumers with shellfish sensitivities.
