A study published by the International Journal of Food Microbiology and designed to verify the effectiveness of Micreos' anti-Listeria phage preparation LISTEX in reducing Listeria monocytogenes on ready-to-eat (RTE) roast beef and cooked turkey showed initial reductions of L. monocytogenes of 2.1 log10 CFU/cm2 and 1.7 log10 CFU/cm2, respectively.
In the study conducted at the University of Guelph, Ready-To-Eat (RTE) meat cores at 4° and 10 °C were inoculated with cold-adapted L. monocytogenes to result in a surface contamination level of 103 CFU/cm2. LISTEX was applied at 107 PFU/cm2 and samples taken at regular time intervals during the RTE product's shelf life.
