Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 1, 2010
End Date: Dec 31, 2013
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 of target pathogens c) Subtype multiple isolates from each positive sample d) Conduct proximate composition analyses on selected foods e) Monitor the fate of target pathogens in higher risk foods in response to food relevant conditions.
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 form each positive sample for subsequent molecular subtyping and perform chemical analyses on food samples as appropriate.
