2011 Annual Report

4. Accomplishments
1. Cold temperature is no problem for Salmonella. How does cold temperature affect Salmonella? An ARS researcher at Princess Anne, MD found that Salmonella can survive well and may even thrive when stored in cold conditions. A computer model was developed to forecast how Salmonella behaves in the cold (39 to 54F). The model was incorporated into the USDA, Pathogen Modeling Program ( where it is being used by USDA and the chicken industry to predict the health risk from chicken stored under optimal and sub-optimal conditions of cold storage.

2. Risk analysis of Salmonella. Each year many Americans are sickened by Salmonella, a major foodborne pathogen frequently associated with poultry meat. To properly predict consumer exposure to Salmonella in food, an ARS researcher at Princess Anne, MD developed a modeling method to calculate the likelihood of Americans getting infected by Salmonella. The new modeling method has great potential to improve accuracy of current risk assessments conducted by regulatory agencies and that are used as the basis for policies and laws aimed at protecting the public from health hazards in the food supply.
