FSIS Guidance for Listeria Sampling27 September 2012
US - USDA Food Safety & Inspection Service (FSIS) announced changes it will make in its procedures for Listeria monocytogenes (Lm) product sampling programmes in ready-to-eat (RTE) meat and poultry products, said the American Meat Institute.
The agency will increase the number of product samples it collects under its routine Risk-based Lm (RLm) sampling programme and its intensified verification testing protocol from three to five samples per sampling unit.
In addition, FSIS laboratories will composite the five 25-g product samples from the RLm sampling programme, which will increase the sample size of the analysed test portion from 25 g to 125 g.
Intensified Verification Testing (IVT) sample size will be five-25 g samples and since these samples are investigative they will not be composited. This will make sampling procedures more consistent with international practices and conserve laboratory resources. Routine monitoring sample sizes for test codes RTE001 and ALLRTE will not change.
