Detroit Food Service Temperature Logging Compliance Checklist

Detroit Health Department Temperature Requirements

The Detroit Health Department requires all food service operations to monitor and document temperatures for time/temperature control for safety (TCS) foods at minimum twice daily—upon receipt and during storage. Refrigeration units must maintain 41°F or below, freezers at 0°F or below, and hot holding at 135°F or above. You must keep written logs for a minimum of 30 days and make them immediately available during inspections. Failure to maintain proper temperature logs results in a code violation under Michigan Food Law; repeated violations can lead to reinspection fees and escalated enforcement.

HACCP Documentation & Calibration Standards

Detroit inspectors verify that your facility uses calibrated thermometers—digital or analog probes must be calibrated monthly using the ice-water or boiling-water method and records documented. Your HACCP plan must identify critical control points (CCPs) for temperature monitoring, specify corrective actions for out-of-range readings, and assign responsibility for daily checks. Logs should include: date, time, food item, temperature reading, thermometer ID, and operator initials. The Detroit Health Department specifically looks for documentation that corrective action was taken when temperatures fell outside safe ranges—missing or delayed responses to temperature excursions are major violations.

Common Detroit Violations & How to Avoid Them

The most frequent temperature-related violations in Detroit include: undated or incomplete logs, lack of thermometer calibration records, failure to document corrective actions for out-of-range temperatures, and missing personnel initials. Inspectors also cite facilities for using single-probe thermometers across multiple units without proper cleaning between uses. To avoid violations, establish a written temperature monitoring schedule, assign staff responsibility, store logs in a secure, accessible location, and conduct monthly staff training on proper thermometer use. Implement a system to alert managers immediately when coolers drift out of range so corrective action (equipment repair, food relocation) is documented in real-time.
