research activities

My research interests include food safety of processed meats, pre- and post-harvest meat animal food safety and consumer acceptance of niche market meat products. Currently, my research focus is on three major projects:

  1. A Systems Approach to Improving the Production and Distribution of Local and Regional Foods for a More Secure Food System: It is a 5-year, $4.8 million UDSA/AFRI funded project to identify gaps in knowledge and practice in the local and regional food system for red meat. The project will start with farmer and producer in-depth surveys and environmental sampling of microflora on farms, in processing facilities and throughout the food chain. After the analysis of data from the initial phase, learning modules to educate farmers and processors will be developed to fill in the gaps in knowledge and practice and create a “Best Practices” outline. The training will be an intensive certification course and following certification, after a time of implementation of the best practices, follow-up surveys and environmental testing will be conducted to assess the impact of the program in reduction of food borne safety hazards.
  2. Antimicrobial Application to Reduce Pathogen Load on Mechanically Tenderized Cuts and on Carcasses: The focus of this project is to find novel ways to introduce antimicrobials, both natural and synthetic as pre-processing technologies, and to reduce the microbial load on the surface of meat cuts destined for mechanical tenderization. There are a variety of companies attempting to validate their technologies, and we are assisting companies as well as investigating our own novel ideas to promote a wholesome and safe food supply.

extension activities

In outreach activities, I seek to help processors throughout the state in addressing their everyday questions related to food safety, processing and business opportunities in meats. Often, people seek advice from my program on the development of meat processing businesses, especially in their efforts to gain knowledge on regulations, safety and business aspects of meat products. 

I also work with numerous on campus and off-campus programs throughout the year in collaboration with Alabama Cattlemen’s Association and/or the ACES to deliver programs to chefs, students, and salespeople in an overview of the full circle of getting beef on the plate from farm to fork.
