Abstract:

Cattle can naturally contain foodborne pathogenic bacteria such as Shiga Toxin-Producing E. coli (STEC). These foodborne pathogenic bacteria are a threat to public health through contamination of foods and water supplies.In order to reduce human exposures and resultant illnesses, research has focused in recent years on the development of live animal intervention strategies that can be applied to reduce the burden of STEC entering the food chain.This review addresses the application of interventions that have been proposed or implemented to reduce STEC in live cattle.Recent years have seen increasing development of new interventions (e.g., vaccination, DFM, chlorate, phages) and into understanding what effect diet and the microbial population have on the microbial populations of the gut of cattle.This research has resulted in several novel interventions and potential dietary additions or changes that can reduce STEC in cattle, and many of them are in, or very near to entering, the marketplace.The live animal interventions must be designed in a coherent, complementary context as part of a multiple-hurdle scheme to reduce pathogens entry into the food supply.
