No history for Salmonella in our process line. It was a suggestion from our FS consultant.
Can we just do random swabbing (monthly monitoring) for our workers?
I suggest you ask yr Consultant to justify his suggestion.
IMEX swabbing of hands/ external clothing are typically included within a routine, risk-based, surveillance program of food-contact/non-contact surfaces. The details, eg scope of micro.analysis, typically relates to the specific situation.
