Seattle Oyster Safety: Regulations & Health Code Requirements

Oyster Sourcing & Harvesting Requirements in Seattle

Washington State requires all oysters served in Seattle to come from approved harvesting areas certified by the Washington Department of Health. Harvesters must follow FDA Interstate Shellfish Sanitation Program (ISSP) standards, which classify growing waters by safety status. Oysters from unapproved or red-tide-affected areas are prohibited and can harbor Vibrio vulnificus, norovirus, or hepatitis A. All oyster shipments must include mandatory tags or labeling with harvest date, location, and supplier information—chain of custody documentation is legally required for traceability.

Temperature Control & Storage Standards for Oysters

Seattle food code mandates oysters be stored at 41°F or below immediately upon receipt and maintained continuously during display and service. Raw oysters for immediate consumption (not cooked) must remain live until service—dead or gaping oysters must be discarded. Oysters cannot be left at room temperature for more than 4 hours total; if ice melts, replacement is required every 2 hours. Seattle & King County Public Health inspectors specifically verify ice logs, thermometer placement, and time-stamped temperature documentation during routine and complaint-based inspections.

Inspection Focus Areas & Compliance Requirements

Health inspectors in Seattle prioritize oyster handler hygiene, cross-contamination prevention, and documentation of time/temperature practices. Facilities must maintain separate cutting surfaces for raw oysters and ready-to-eat foods; glove changes between handling oysters and other items are mandatory. Restaurants must retain shellfish supplier records, harvest tags, and temperature logs for 90 days minimum. Violations related to oyster storage temperature or missing harvest documentation typically result in corrective action notices; repeated infractions can lead to license suspension or closure.
