Controlling Foodborne Infections in Lettuce: Testing and Cleaning Methods for Curbing the Spread of E. coli O157:H7

Abstract:

E. coli O157:H7 bacteria tends to contaminate leafy green vegetable farms regularly, therefore promoting a recurrence in foodborne disease outbreaks. In previous studies, E. coli in water has been a focus. However, the farming industry is just now understanding the danger of E. coli in soil. In spring 2018, lettuce farms in the Yuma region contracted the E. coli bacteria and caused 210 human cases nationwide. As a result of this study, a new mathematical framework is proposed to capture the dynamics of the spread of E. coli in lettuce due to contaminated soil and equipment. In particular, this framework explores the impact of soil treatment and equipment sanitation since they are essential to the growing process of lettuce.
