Time Temperature Log
🌡️ Time Temperature Log
The Time Temperature Log is one of the most essential tools in restaurant food safety management. It ensures that all hot‑held foods remain at safe temperatures throughout service, protecting guests from foodborne illness and helping your team maintain compliance with health department standards. Every restaurant that uses steam tables, hot holding units, or buffet lines should have a reliable time temperature log system in place.
🔍 Purpose and Importance
The Time Temperature Log is used to record the temperatures of all foods stored in hot holding units such as steam tables, soup warmers, or hot boxes. Recording temperatures at regular intervals — typically every two hours — helps verify that food remains above the critical safety threshold of 140°F (60°C). If any item falls below that temperature, it must be reheated to an internal temperature of 165°F (74°C) for at least 15 seconds before being served again.
This process prevents bacterial growth and ensures compliance with HACCP (Hazard Analysis Critical Control Point) standards. The log also provides documentation for health inspections and internal audits, proving that your restaurant consistently monitors food safety.
🍲 Proper Reheating Methods
When reheating food that has dropped below 140°F, use one of the following approved methods:
- Stovetop reheating — ideal for soups, sauces, and liquids.
- Oven reheating — best for baked or roasted items.
- Steam or microwave reheating — suitable for quick recovery of small portions.
Never attempt to reheat food directly in a steam table or holding unit. These devices are designed only to maintain temperature, not to raise it. Always reheat using proper cooking equipment before returning food to the holding unit.

🕒 Recording Intervals and Procedures
Record product temperatures every two hours while food is held. Each entry should include:
- The time of measurement
- The food item name
- The temperature reading
- The employee initials
If a product fails to meet temperature requirements, note the corrective action taken (e.g., “Reheated to 165°F for 15 seconds”). Discard any food that remains below 140°F for more than two hours. To reduce waste, prepare smaller batches more frequently rather than holding large quantities for extended periods.
📉 Reducing Food Waste
Pair your Time Temperature Log with the Food Waste Sheet to track discarded items and identify patterns. Recording waste helps managers pinpoint overproduction, improper holding, or equipment issues. Over time, this data supports better inventory control and cost savings.
🧾 Compliance and Documentation
Maintaining accurate temperature logs is not just good practice — it’s required by most local health departments. Logs serve as proof that your restaurant follows safe food handling procedures. In the event of a food safety complaint or inspection, your documentation demonstrates due diligence and adherence to federal guidelines.
For official guidance, review:
- FDA Food has more information on the importance of food temperatures.
- U.S. Department of Agriculture (USDA) Food Safety and Inspection Service: has more information on the safe temperatures for food
- Centers for Disease Control and Prevention (CDC) – Foodborne Illness Prevention: has basic food safety information.
These resources outline temperature standards, safe reheating procedures, and corrective actions for food service operations.
📋 How to Use the Time Temperature Log Form
- Print and laminate the Time Temperature Log for daily use.
- Assign responsibility to a trained employee for monitoring and recording temperatures.
- Keep completed logs in a binder for at least 90 days for inspection reference.
- Review logs weekly to identify trends or recurring issues.
- Cross‑reference with your Food Waste Sheet to track losses and improve efficiency.
