Seattle Restaurant Temperature Logging Requirements & HACCP Compliance

Seattle & King County Temperature Logging Rules

King County Health Department requires all food service establishments to log temperatures for cold storage units (must stay at 41°F or below) and hot holding equipment (165°F or above) at least twice daily—typically at opening and closing. The Seattle Food Code, adopted from Washington State Food Code, mandates written records be kept for a minimum of 30 days. Temperature logs must include the date, time, temperature reading, equipment identification, person taking the measurement, and corrective actions if temps fall out of safe ranges. Inspectors specifically check that logs are complete, legible, and accessible during unannounced visits.

HACCP & Cooking Temperature Documentation in Washington State

Washington State requires establishments serving potentially hazardous foods to implement Hazard Analysis and Critical Control Points (HACCP) plans, which include cooking temperature verification as a critical control point. Foods like ground meats must reach 155°F, poultry 165°F, and seafood 145°F—and these temperatures must be logged with a calibrated thermometer. Unlike the FDA's federal guidelines, Washington State's Food Code (Chapter 246-215 WAC) mandates that critical cooking temperatures be documented for each batch or service period, not just spot-checked. Hand-written logs, digital systems, and automated monitoring devices all satisfy compliance, provided records are timestamped and retained for 30 days minimum.

How Seattle Standards Differ from Federal FDA Requirements

While the FDA Food Code recommends temperature monitoring, Washington State and Seattle enforce it as a mandatory, documented requirement with legal penalties for non-compliance. The FDA's guidance suggests logs be kept for "a reasonable time," but Seattle's King County Health Department specifies 30 days minimum and expects daily verification. Seattle also has stricter enforcement frequency—health inspectors check temperature logs at every inspection, whereas federal FDA oversight is limited to occasional compliance audits. Additionally, Seattle requires staff training documentation on proper thermometer use and temperature monitoring procedures, going beyond the federal baseline of general food safety knowledge.
