Hi everyone, is there any limit time as tolerance associate with temperature limit (CCP) for cold and frozen storage of foods?References normally only refers to temperature, example 5-7C critical limit for chilled and -18C for frozen products. Is there any tolerance time for eventual temperature fluctuation that exceed the limit for a short time? 1hour? 4 hours? I cannot find reference for that time tolerance.

Perishables should not be stored out of temp no longer than 2 hrs.

I hope this article helps

Set both activities as PRPs as implied per iso22002-1 so no need for "Critical Limits".

 

For chilled storage, recommended limits may vary with geographical location, for example, IIRC in UK target for a refrigerator is <5degC but max acceptable 8degC. For USA IIRC absolute max is 4.4degC.

 

For frozen storage, IIRC, EC allow "short intervals" of cold storage air temperature up to -15 (maybe -16) degC. (eg when fan coils are defrosting)

 

References from memory on FSA, EC and FDA websites respectively.

 

afaik, chilled storage temperature limits are typically not (time) associated with deviations exceeding maximum.
