1) Develop methods to prevent bacterial foodborne pathogens from contaminating poultry processing plant environments and reduce the level of these pathogens on live birds and finished products; and 2) Determine ways to improve the microbiological quality and shelf life of ready-to-eat poultry products and fruits and vegetables through design of appropriate microbiological sampling techniques and sampling plans.
