Temperature Monitoring

If using a DDL: 

  • Most DDLs display minimum and maximum temperatures.
  • Check and record the minimum and maximum temperatures at the start of each workday.
  • If the DDL doesn’t display the min/max temperatures:
    • Check and record the current temperature at the start and end of each workday.
    • Review the continuous DDL temperature data daily.

Document temperatures using the appropriate log: 

  • Temperature logs (C° or F°) for freezers 
  • Temperature logs (C° or F°) for refrigerators 

Save documentation for 3 years, unless your state/local jurisdiction requires a longer time period.
