During the Generic E. coli verification task, IPP are to verify all of the following regulatory requirements except which?

• A. A very low volume establishment is performing sampling at least weekly, starting June 1 of each year
• B. The establishment is charting results of generic E. coli (or other microbial) sampling
• C. The establishment is performing statistical process control (SPC) on the results of sponge sampling
• D. NRs are issued for all results that exceed the upper control limit ('M') value

Answer: (D)

The question is testing what practices must be verified for the Generic E. coli verification task. You should see that ensuring weekly sampling by a very low volume method, keeping and charting the results of generic E. coli or other microbial sampling, and applying statistical process control to sponge sampling are all expected verification activities. These elements establish that sampling occurs regularly, data are captured, and the process performance is monitored over time. The statement about issuing nonconformance reports for every result that exceeds the upper control limit is not a regulatory requirement you’re asked to verify in this context. In a statistical process control framework, an out-of-control signal (a point beyond the upper control limit, M) prompts investigation and corrective action, but issuing a nonconformance report for every single exceedance is not inherently mandated as part of the generic E. coli verification task. The actual procedures for documenting and responding to out-of-control results are determined by the establishment’s CAPA system and regulatory guidance, rather than being a fixed verification checkpoint. Therefore, that item is not a required verification element, making it the exception.
