Qualitative L.monocytogenes in Meat Matrix PT Express

A three sample set for qualitative identification of L. monocytogenes. Set is designed to mimic typical FDA BAM and USDA MLG sample handling procedures.

At least one of three of the sample pellets will be positive for L. monocytogenes. To use, transfer 25 grams of sterile matrix to stomacher bag, add 225 mL of laboratory supplied enrichment broth and then add a single sample pellet to the stomacher bag. Process and analyze according to your normal laboratory procedures. Report present or absent for each sample set. Three different series available per study.
