If you run a food truck in Utah, your temperature logs are one of the first things a health inspector will check. Missing or incomplete logs can lead to violations, even if your food is safe. This article breaks down exactly what Utah law requires for temperature monitoring and recordkeeping, so you can stay compliant and pass inspections with confidence.
Which of the following is the correct cold-holding temperature for TCS food when received at a Utah food truck?
Select one answer.
What Utah law says about temperature control
Utah's Mobile Food Business Sanitation rule (R392-102) sets strict temperature requirements for time/temperature control for safety (TCS) foods. Under R392-102-12, refrigerated TCS food must be at 41°F (5°C) or below when received from a commissary or other approved source. Hot-held TCS food must be at 135°F (57°C) or above upon receipt. Frozen foods labeled as such must arrive frozen and be maintained frozen until cooked or served.
These rules apply from the moment food enters your truck. Your temperature log is the primary way to prove you're meeting these standards.
What to record on every log entry
Each temperature log entry should capture six key pieces of information, according to industry best practices and what inspectors expect:
- Date and time of the reading
- Equipment or food name (e.g., "main cooler," "steam table," "chicken batch")
- Actual temperature reading in Fahrenheit, using a calibrated probe thermometer
- Staff initials of the person who took the reading
- Corrective action if the temperature is out of range (e.g., "adjusted thermostat, moved food to working cooler")
- Verification that the corrective action brought the temperature back into compliance
Health inspectors want to see at least 7 days of consistent records during an inspection. A log with gaps or missing corrective actions can signal poor monitoring practices.
How often to check temperatures
Utah law does not specify an exact frequency for temperature checks, but the FDA Food Code (incorporated by reference in R392-102) recommends checking at least every four hours during operation. For food trucks, where cooler doors open frequently and ambient heat is a factor, many operators check every two hours during peak service.
Best practice is to log temperatures:
- At the start of each shift (before service begins)
- At least every two to four hours during operation
- After any corrective action is taken
- At the end of the shift
Common mistakes that lead to write-ups
Inspectors commonly flag these temperature log issues:
- Missing dates or times — gaps in the log suggest you aren't checking regularly
- No corrective actions — an out-of-range reading without documentation of what you did is a red flag
- Using uncalibrated thermometers — your probe thermometer should be calibrated daily and logged on a separate calibration log
- Not logging all equipment — every cooler, freezer, hot-holding unit, and cooking surface needs its own entries
How long to keep temperature logs
Utah's R392-102 does not specify a retention period for temperature logs, but the FDA Food Code recommends keeping records for at least 90 days. Many local health departments in Utah expect you to have at least the most recent 30 days of logs available during an inspection. To be safe, keep all logs for at least three months and replace them with fresh sheets regularly.
Setting up a simple logging system
You don't need expensive software. A simple binder with pre-printed log sheets works well. Include these core documents alongside your temperature logs:
- Daily fridge/freezer log
- Cooking/reheating log
- Hot holding log
- Thermometer calibration log
- Cleaning schedule / sanitation record
Keep the binder in an accessible spot in your truck. Inspectors will ask for it, and having it organized shows you take food safety seriously.
