Hi, I got a technical question after checking someones hazard risk assessment and control measure determination. The person identified antibiotic residue in milk as a chemical hazard, his control measure is, checking the antibiotic residue in milk using rapid test kit for screening. While calculating the score for determining CCP/OPRP, he showed that there is high probability of failure of control measure (Score 3). Cumulatively, it made the total score above the threshold value to determine the CCP.
Now my question is, in this case, high likelihood of failure means the failure of the test kit to determine the presence of antibiotic residue (Please correct me if I am wrong). Then, how is this CCP being controlled? Does it make any sence really? To me, if his test kit is not reliable enough, how he is controlling that CCP?
Honestly, I am bit confused with the term likelihood of failure. Which failure it actually means? I would be happy for the clarification.
