Our Programs

Programs run quarterly and are prorated if an individual chooses not to participate in all four quarters. Participants may analyze the test items for any, or all, of the tests specified for the given program.  Cherney will work with our customers to determine if their internal products and methods are comparable to our programs and matrices and help work through any troubleshooting that may arise. Should an unsatisfactory or unacceptable result be produced, customers may choose to participate in our Cherney Recheck program as well.

Program History

 Driven by customer request, Cherney Microbiological Services launched its first program in the early 1990s. Two additional programs, Dry Whey and Basic Microbiology, were then added. This initial cheese program was then later split into three, allowing for more specification of cheese product type. Cherney currently offers seven proficiency programs, five of which are ISO accredited
