Temperature Logging Requirements for San Francisco Food Businesses

San Francisco Temperature Logging Legal Requirements

The San Francisco Department of Public Health requires all food facilities to maintain accurate temperature records for potentially hazardous foods. Under California's Retail Food Code (Section 113996), hot foods must be held at 135°F or above, and cold foods at 41°F or below. SF health inspectors specifically verify that facilities log temperatures at least twice daily (beginning and end of service), document the date, time, equipment used, and corrective actions taken. Logs must be kept on-site for a minimum of one year and made available during unannounced inspections. Non-compliance can result in citations, operational restrictions, or closure orders.

HACCP Documentation & Inspector Enforcement

San Francisco inspectors use HACCP (Hazard Analysis Critical Control Points) principles to evaluate food safety systems. Temperature logs are a primary HACCP control point—inspectors verify that critical control limits are established, monitored, and documented. During inspections, officials check for gaps in logging, missing corrective action records, and improper thermometer calibration (which must occur quarterly per CA code). The SF Department of Public Health prioritizes facilities handling high-risk foods like raw seafood, deli meats, and ready-to-eat items. Violations of temperature documentation can result in conditional permits or mandatory manager training requirements.

Best Practices for SF Compliance & Record Management

Implement digital temperature monitoring systems that automatically timestamp and store logs—this simplifies compliance and reduces human error. Calibrate all thermometers (both analog and digital) quarterly using ice-point and boiling-water methods, and document each calibration. Train all staff on proper probe placement (center of thickest part of food), hand-washing before logging, and immediate reporting of out-of-range temperatures. Establish a clear corrective action protocol: if a temperature is out of range, document the time, cause, action taken (e.g., reheating, discarding), and who performed it. Keep both digital and printed backup records; SF inspectors appreciate redundancy. Review logs weekly to identify trends and prevent systemic failures.
