Onion Safety in San Francisco: What You Need to Know

San Francisco Health Code Requirements for Onion Storage & Handling

San Francisco's Department of Public Health enforces California Health & Safety Code § 113952, requiring all food facilities to maintain proper temperature controls and prevent cross-contamination. Raw onions must be stored separately from ready-to-eat foods and proteins, with documented storage temperatures logged daily. Restaurants and grocery stores are required to implement HACCP (Hazard Analysis Critical Control Points) protocols and train staff on proper handling. The SF Health Department conducts routine inspections and issues violation reports for non-compliance, which are publicly available online. Both consumer-facing businesses and institutional kitchens (schools, hospitals) must comply with these same regulations.

Common Onion Contamination Risks & Recent Recall Patterns

Onions have been linked to multiple multistate recalls due to E. coli O157:H7 and Salmonella contamination, typically originating from soil or irrigation water exposure. The FDA and FSIS track these recalls through their Enforcement Reports and Recalls database, which lists affected states and distribution channels. In 2024-2025, several major suppliers distributed contaminated onions across California, including the Bay Area, prompting retail and foodservice recalls. Consumers should be aware that contamination risk is highest with raw or lightly cooked onions; thorough cooking to an internal temperature of 165°F reduces pathogenic risk significantly. Cross-contamination in home kitchens—cutting raw onions on the same board as raw meat without sanitizing—is also a documented risk factor.
