Hi,

Anyone working in Dairy Hazard Area?. Could you please share with me regarding the Pasteurizer calibration interval that you adopt for your company?

Dear Anish, to the club.

I dont have any experience about dairy industries, but some members here are well-known experts on this area.

In ISO 22k, it said that "The measuring equipments and methods used shall be calibrated or verified at specified intervals, or prior to use, against measurement standards..."

So, the key is the specified and determined intervals. The FDA mentioned on one of their guidance-its talkin bout seafood but I guess technically its the same:

optimal calibration frequency is dependent upon the type, condition, and past performance of the monitoring instrument

So I guess you need to consider all of them, before determine your calibration interval. The rest of it can be seen down here:

On the other hand, The Canadian Food Inspection Agency set this thing more clearly:

The thermometer shall be accurate to within +/- 0.25°C (0.5°F) throughout the specified scale range and shall be calibrated upon installation and at least every 6 months thereafter using a thermometer of known accuracy.

I took it from their Dairy Establishment Inspection Manual, and here is the link (in 1.12.03.03 section):

Hope they might help you out.

Arya

We do crack testing annually and calibration 6 monthly.

IMEX.. we do calibration 6 monthly.. and we do calibration for temperature gauge, temperature sensor.. and time of calibration...actually if you have some data calibration you can set the interval based on your historical data..

Dear AS NUR,

actually if you have some data calibration you can set the interval based on your historical data..

Is it possible to describe how you do this ? I presume the method is empirical.

@ Arya, thks for the links, useful stuff.
