Cooling Log

A cooling log is a food safety documentation tool used to record the cooling times and temperatures for hot foods that are cooked and cooled for later use, verifying compliance with the FDA Food Code's two-stage cooling requirements (135°F to 70°F within 2 hours, then 70°F to 41°F within 4 additional hours).

A cooling log is a food safety documentation tool that records the time and temperature measurements for hot foods being cooled for later use. Required by health departments as part of HACCP-based food safety programs, these logs verify that cooked items like soups, sauces, roasts, beans, and rice move through the temperature danger zone quickly enough to prevent bacterial growth.

The Two-Stage Cooling Method

The FDA Food Code mandates a specific two-stage cooling process that must be documented on cooling logs. Food must first cool from 135°F to 70°F within 2 hours, then from 70°F to 41°F or below within an additional 4 hours—a total cooling time of 6 hours maximum. This timeline isn’t arbitrary; bacteria multiply rapidly between 70°F and 135°F, making the first two hours the most critical window.

To meet these strict requirements, kitchen staff use techniques like spreading hot food in shallow metal hotel pans, stirring every 15 minutes, employing ice paddles or ice baths, and avoiding stacking pans in refrigerators. High-volume operations often invest in a blast chiller to rapidly cool large batches and consistently meet the time standards.

What Goes on a Cooling Log

Every cooling log entry must include the product name, start time when food reaches 135°F, temperature readings at the 2-hour and 6-hour checkpoints, and the employee’s initials. These readings are taken with a calibrated probe thermometer inserted into the thickest part of the food. If temperatures don’t meet requirements at either checkpoint, corrective actions must be documented immediately.

Corrective actions typically involve reheating the food to 165°F within 2 hours if it’s still safe to salvage, or discarding the product entirely if it’s been in the danger zone too long. Whatever action is taken must be noted on the log with a time stamp and signature. These aren’t suggestions—they’re legal requirements that protect both customers and the business.

Why Cooling Logs Matter in HACCP Programs

Cooling logs are one of five standard temperature logs used in HACCP programs, alongside hot holding, cold holding, receiving, and cooler/freezer logs. In HACCP terminology, cooling is classified as a Critical Control Point (CCP) because improper cooling is a leading cause of foodborne illness outbreaks. The log provides verifiable evidence that this critical step is being monitored and controlled.

During a health inspection, inspectors will review cooling logs to verify compliance with local regulations. These documents are also considered discoverable legal evidence in court if a foodborne illness claim arises. Incomplete, falsified, or missing logs can result in violations, fines, or even temporary closure.

Retention and Storage Requirements

Completed cooling logs must be retained for 90 days to 6 months depending on local health department regulations. Most operations store logs in a designated binder near the prep area for easy access during inspections. Digital logging systems are increasingly common, offering automatic timestamping and cloud backup to prevent lost records.

Batch cooking operations generate the most cooling log entries, as prep cooks regularly prepare large quantities of sauces, stocks, and proteins for later service. Establishing a routine—checking temperatures at consistent intervals and documenting immediately—turns this regulatory requirement into a simple daily habit that protects food safety.

Common Uses

Cooling logs are used daily in restaurant kitchens during prep shifts when hot foods are prepared in advance. Prep cooks complete entries after batch cooking items like soups, sauces, stocks, beans, rice, roasted meats, and cooked vegetables. The log sits near the walk-in cooler or prep station where a calibrated probe thermometer is accessible. Kitchen managers review logs during shift changes to verify compliance, and health inspectors examine them during routine visits. Properly maintained cooling logs demonstrate due diligence in a restaurant's food safety plan and provide legal protection in case of foodborne illness investigations.

Frequently Asked Questions

Food must cool from 135°F to 70°F within 2 hours, then from 70°F to 41°F within an additional 4 hours (6 hours total). This two-stage approach prevents bacterial growth in the temperature danger zone, with the first stage being most critical since bacteria multiply fastest between 70°F and 135°F.
If food fails to cool properly within the required timeframes, it must either be reheated to 165°F within 2 hours or discarded immediately. The corrective action taken must be documented on the cooling log with a time stamp, employee initials, and explanation. Attempting to serve food that hasn't cooled properly violates health codes and creates serious food safety risks.
Retention requirements vary by jurisdiction, typically ranging from 90 days to 6 months. Check your local health department regulations for specific requirements. Many operations keep logs for 6 months as a best practice, storing them in dated binders or digital systems that allow quick retrieval during inspections or in case of foodborne illness investigations.
Time/Temperature Control for Safety (TCS) foods that are cooked and cooled for later use require cooling logs. Common examples include soups, stocks, sauces, gravies, beans, rice, pasta, cooked vegetables, roasted meats, pulled pork, chicken salad, and potato salad. Raw foods that are simply refrigerated don't need cooling logs—only cooked items being cooled from hot temperatures.
Use shallow metal pans no deeper than 4 inches rather than deep containers, stir food every 15 minutes to release heat, use ice paddles or ice baths to cool from the inside, don't stack pans in the refrigerator (allow air circulation), and place food uncovered in the cooler once it reaches 70°F. Blast chillers rapidly cool large batches and virtually guarantee compliance with the two-stage method.
