|Title:||Pathogen Mitigation in Livestock and Red Meat Production|
|Objective:||The overall goal of this project is to increase the microbiological safety and quality of red meat by reducing or eliminating foodborne pathogens. Accomplishment of this goal will require basic and applied research objectives targeted throughout the forkto-farm food-chain. |
Although this project has in the past and will always provide assistance to all three areas of red meat food safety (i.e., beef, lamb, and pork), the research proposed herein is weighted heavily towards beef as recent increases in recalls and illness outbreaks have been particularly detrimental to the beef industry.
This project focuses on the three primary red meat-related foodborne pathogens: Escherichia coli O157:H7, non-O157 Shiga toxin-producing E. coli (STEC), and Salmonella. E. coli O157:H7 receives the bulk of the research attention as it is the highest food safety priority of the beef industry. The three objectives of this project address needs in antimicrobial intervention, pathogen detection, and host-pathogen interaction. Experiments are proposed to develop and evaluate novel interventions for pathogen mitigation for the live animal in production and lairage environments, for carcasses at multiple stages of processing, and for the finished product.
In conjunction with intervention development, improvements to detection methodology and pathogen source identification are proposed for cattle production and processing, as well as the finished product. Finally, basic research of host-pathogen interactions will provide the basis for future developments in pathogen detection and intervention.
|More Info:||The meat processing industry will gain additional tools in the fight against pathogen contamination of carcasses and, ultimately, retail meat products. FSIS will receive pertinent information on which to base food safety policies and regulations. Successful completion of the objectives will benefit processors by increasing their ability to monitor production and develop improved interventions to minimize contamination and product loss, and will benefit consumers by decreasing the risk of foodborne illness.|
