The Better Process Control Schools (BPCS) certify supervisors of thermal processing systems, acidification, and container closure evaluation programs for low-acid and acidified canned foods. Each processor of low-acid or acidified foods must operate with a certified supervisor on hand at all times during processing.

FDA's regulations in 21 CFR 108, 113, and 114 became effective May 15, 1979. These regulations are designed to prevent public health problems in low-acid and acidified low-acid canned foods. The BPCS provide the practical application of the principles set forth by these regulations. These FDA regulations also apply to low-acid canned pet foods.
