Choice of product

Some particular points of interest to fight against Listeria:

·         Cleaning is more important than disinfecting

·         Respect the instructions of use from the cleaning or disinfecting product.

·         BPR Guideline => Listeria is easy to destroy, specific tests and claims are nog obliged.  

The test organisms used in efficacy tests are normally stated in the applicable standard test methods. For food area disinfectants Salmonella Thyphimurium, Salmonella spp., Listeria spp. and Campylobacter jejuni are relevant target organisms. For products which claim general efficacy against bacteria, the standard test bacteria should be tested. For these products efficacy against Salmonella spp., Listeria spp. and Campylobacter jejuni is assumed, because they are more susceptible than the standard test bacteria.
