"22.214.171.124 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? OR does this mean we have to challenge our accuracy by (for example) placing two identical yeast and mold plates at each test site, and send one set of plates to the lab for counting in order to compare our in-house count?
Thank you for the help in interpreting this clause
typical SQF confusing semantics.
Previous threads seem to primarily support the latter option of above although I suppose the latter if unsuccessful might ultimately involve the former, eg -
(the 2nd link of above 4 seems popularly cross-referenced in some of the others, its quoted paragraph is from the SQF Guidance)
