Hello,
Firstly, I work to BRC standards so sorry if this isn't relevant, but from what i can gather:
To comply with this clause all you need to do is have an environmental monitoring procedure with a schedule for sampling.
For example, at my place, swabbing takes place quarterly.
The schedule shall include the mentioned:
• sampling protocol (the procedure you have in place for sampling)
• identification of sample locations (what areas are you swabbing)
• frequency of tests (how often are you swabbing)
• target organism(s) (e.g. pathogens, spoilage organisms and/or indicator organisms) (what are you testing for)
• test methods (e.g. settle plates, rapid testing, and swabs)
• recording and evaluation of results. (how are the results analysed for trends, etc.)
If the microorganism hazard is really low, then just set some control limits that are relevant to your facility, or control limits that you wish to remain within as a company, like an objective for an example.
For example:
If results from swabbing fall outside of A-D then there is a food safety issue, but if swabbing falls outside of B-C then there is a quality issue against our own expectations / standards as a company.
I hope this makes sense.
