My plant has its own category 1 testing lab, but we can test for Salmonella (because its a category 2 pathogen). Therefore we need to split our test samples and send the Salmonella out to a contract lab, is it okay to do that?
Yes. The FSA advises that, for situations like this in red meat plants, sponge sampling be used. The sponge samples should be taken back to the plant’s lab where a known volume (e.g. 90ml) of buffered peptone water is added to them. After stomaching the sponge, sufficient liquid (5-10ml) should be removed for TVC and Enterobacteriaceae testing. The remaining BPW and the sponge should be sent on to the contract lab for enrichment and Salmonella testing.
