The Food Safety (Temperature Control) Regulation 1995 came into force in September 1995 and have replaced earlier controls under the Food Hygiene (Amendment) Regulations 1990 and 1991.
Whilst these regulations Stipulate a single temperature limit of 8C for the storage and transportation of chilled foods, there is no specific legal requirement covering the fitment or use of automatic temperature monitoring devices.
However, there is an obligation to measure air temperature at regular intervals and keep records to prove compliance with the regulations. These records can be produced manually or automatically at the operator's discretion.
