Research Project: PREVALENCE AND LEVELS OF LISTERIA MONOCYTOGENES IN READY-TO-EAT RETAIL MEAT AND POULTRY PRODUCTS (DREXEL UNIV)

Location: Food Safety and Intervention Technologies

Project Number: 1935-41420-015-09
Project Type: Specific Cooperative Agreement

Start Date: Jul 01, 2011
End Date: Oct 31, 2012

Objective:
Quantify the occurrence of foodborne pathogens in select foods: a.) Screen foods for the presence/absence of target pathogens. b.) Determine levels of target pathogens in selected foods. c.) Subtype multiple isolates from each positive sample. d.) Conduct proximate composition analyses on selected foods.

Approach:
Work with FDA, USDA/ARS, and USDA/FSIS and associated industry partners to collect/purchase targeted food samples from retail establishments. Test samples for presence/absence of target pathogens, determine the levels of the pathogen(s) in each positive sample by direct plating or enrichment. Retain multiple isolates from each positive sample for subsequent molecular subtyping and perform chemical analyses on food samples as appropriate.
