We're a company that produces food processing aids. During our recent SQF Audit, the auditor found a single ant on our production floor and gave us a minor non-conformance for it. We did a brief survey of the area and could not find any additional ants or ant trails, nor reasons for the ant being in the area, such as food or food wrappers. We don't even us raw materials that would be considered as attractants to ants, other than maybe water. Anyway, this leaves numerous possibilities for the reasons how the ant got into the area, and I believe most likely it was carried in there by some other means. Heck, even the auditor could have carried it into the area via her shoes. My question is, what do I put down for a root cause for our response to the find?
Thanks in advance:-)
