This is for Listeria spp. AOAC PTM 020401
Upon arrival, the sample’s temperature and client supplied sample date are checked to make sure everything is within validated conditions.
We confirm that the sample identifiers and requested tests on the submission form match the labels and details on the actual sample.
The sample is incubated in selective growth media at 30°C for 40–48 hours to allow any Listeria spp. present to reach detectable levels.
Each sample is removed from incubation, and an aliquot is transferred to a separate tube for heat treatment at 95–100°C for ten minutes.
The sample is removed from the heat step and allowed to cool for ten minutes before proceeding to analysis.
A special test strip is placed in the tube for ten minutes, and the results are read and by one of our microbiologists.
Results are documented on our tracking form. Reports are made, reviewed, and sent as a pdf via email to our clients.
results pertain only to the submitted sample and may not be construed as an endorsement of the sampling method
