The STEC CAP grant awarded two 12-month grants (each at $50,000 maximum, including indirect costs) to officially designated Minority Serving Institutions (MSI).  The funded MSI research projects:
  1. Focus on understanding and controlling foodborne risks associated with Shiga toxin-producing Escherichia coli in U.S. veal production and processing
  2. Contribute research data relevant to understanding and controlling STEC across the beef system and/or educational and outreach programs to ultimately reduce public health risks associated with STEC-contaminated beef products.

MSI Research Award

Congratulations!Dr. Amitra Jackson-Davis

Dr. Amitra Jackson-Davis’s Project is entitled "Quantifying the impact of intervention technologies and/or control practices applied at pre-harvest production and post-harvest processing stages of beef manufacturing." This project’s research will investigate the effectiveness of UV light treatment and ultrasound in combination with organic acids and surfactants on the inactivation of non-O157 and O157:H7 STEC on beef trim.

The long-term goal of this work is to improve the safety of beef products by developing "multiple-hurdle" intervention systems, which would inactivate STEC on beef. This work will provide insight into the effectiveness of the proposed multiple-hurdle antimicrobial technologies on the inactivation of non-O157 STEC. Processors will be able to use this information in controlling different serotypes of E. coli in beef products.

Project Title: Prevalence and Characterization of Escherichia coli O157:H7 Recovered from Retail Ground Veal in Mid-Atlantic Region of the United States.

Summary: Shiga toxin-producing Escherichia coli, especially E. coli O157:H7 is a significant public health concern in many countries and associated with a broad spectrum of infections which range from mild diarrhea to hemorrhagic colitis and hemolytic uremic syndrome. Recently, recalls of several thousand pounds of E. coli O157:H7 contaminated retail veal from multiple states have resulted in an increased interest of this pathogen. In addition, sampling of beef and veal trim by the United States Department of Agriculture (USDA) Food Safety and Inspection Service (FSIS) has shown a higher recovery rate in veal. The objectives of this study are to: 1) determine the prevalence of E. coli O157:H7 in retail ground veal collected from Maryland, Delaware and Virginia; 2) determine the presence of virulence genes; and 3) characterize E. coli O157:H7 isolates by phenotypic and genotypic methods. The findings of this project will not only fill the data gap of STEC CAP grant’s goal but also provide information that is critical for meat industry and USDA/FSIS to develop a scientifically supportable regulatory food safety policy related to the public health impact of E. coli O157:H7.
