We recently ran some Standard plate count, yeast and mold tests and received the following results:
SPC 1 CFU/ 15 min
SPC 10 CFU/ 15 min
Yeast <1CFUs/ 15 min
Yeast <1 CFUs/ 15 min
Mold 3 CFUs/ 15 min
Mold 10 CFUs/ 15 min
The compressed air has a 0.1 micron filter on it, and we will be changing it every 3 months.
The compressed air is used for food contact during the process.
Im having a hard time finding the industry standards for this.
Once i get a a few months of data and all the results are within the acceptable limits, i would like to reduce the frequency of testing. After i do this is it really necessary to run all 3 tests? or is SPC or APC acceptable?
