Oyster Safety & Handling Regulations in San Francisco
San Francisco's Department of Public Health enforces strict oyster handling standards to prevent shellfish-borne illnesses like Vibrio and Norovirus. Restaurants and retailers must comply with California's shellfish sanitation program, FDA guidelines, and local health codes—failure to do so results in citations and potential closure. Understanding these regulations protects your business and customers.
San Francisco Oyster Sourcing & Certification Requirements
All oysters sold in San Francisco must come from FDA-approved sources certified by the California Department of Fish and Wildlife (CDFW). Vendors must maintain chain-of-custody documentation and tag oyster shipments with harvest location, date, and shipper information. The San Francisco Health Code requires businesses to keep oyster source records for a minimum of 90 days and make them available during inspections. Oysters from uncertified or closed harvest areas are prohibited and result in immediate seizure and fines.
Temperature Control & Storage Compliance
SF health inspectors mandate oysters be stored at 41°F or below, with live oysters kept on ice in properly draining containers to prevent pooling. Oysters must never reach temperatures above 41°F for more than 2 hours (1 hour if the ambient temperature exceeds 90°F). Establishments must use calibrated thermometers and maintain temperature logs for walk-in coolers and reach-in refrigerators. Post-harvest treatment (like depuration or relaying) must be documented, and oysters cannot be served if shell integrity is compromised or if they've been dead for longer than permitted under San Francisco Health Code Chapter 25.
Inspection Focus Areas & Common Violations
SF health inspectors prioritize oyster handling during routine and complaint-driven inspections, checking for proper labeling (harvest date, source, shipper name), cross-contamination risks, and employee hygiene practices. Common violations include storing oysters above ready-to-eat foods, failing to date-mark opened containers, serving raw oysters without proper allergen disclosure, and inadequate training on Vibrio risk during warm months. Establishments must display oyster provenance information to customers upon request, and raw bars must display warning signs about risks from consuming raw shellfish. Repeat violations trigger re-inspection, escalated penalties, and potential permit suspension.
