We are an RTE Facility that produces Poultry Products, recently they have started using the NEOGEN ANSR kit to test for Listeria Monocytogenes on the production lines but they have been taking the samples while the lines are Running & have product on it.
When I was checking the NOGEN manual, the following was mentioned in the intended use:
"This environment test can be used on stainless steel, sealed concrete, ceramic tiles, rubber and plastic. It was validated by the AOAC for stainless steel and sealed concrete surfaces. It is not designed for soiled samples or food matrices testing."
I do not have a lot of experience in microbiological & environmental sampling, and it is the first time for me to see samples taken from lines with products on it.
We take samples for the line after sanitation & from the product and send them to external laboratory, they do the NEOGEN samples for internal monitoring.
My question is: Is this a correct way to take the sample and to ensure the results are reliable?
