Dr. Crandall's research is focused on retail food safety and the use of green technologies that minimize the risk from foodborne pathogens for consumers from farm to fork. Using basic and applied science, Dr. Crandall develops novel approaches and solutions for food safety issues from the processing plant through retail.
- Look system-wide to determine the most efficient intervention points to reduce consumers’ risk from consuming goods prepared in retail food establishments.
- Establish the impact on reducing risk of sanitizing agents, cleaning cloths, novel antimicrobials, cleaning methods and sanitizing practices to minimize the risk of cross-contamination by Listeria monocytogenes.
- Determine the role of retail equipment and employees in foodborne illness from minimally processed and ready to eat foods, especially from L. monocytogenes.
- Establish and verify the impact of an outreach education and training program for processors, retail food service workers, and consumers.
