"188.8.131.52 On-site personnel that conduct ENVIRONMENTAL or product testing shall participate in an applicable proficiency testing program at least annually to ensure accuracy of results"
Does this mean personnel doing environmental testing (like doing yeast and mold plates in-house) have to have some special training once a year?
