Shiga Toxin E. coli Study in East Lansing
E. coli outbreak researchers at Michigan State University will study strategies to reduce the amount of E. coli released by cattle under a $2.5 million grant from the U.S. Department of Agriculture. The hope is that a reduction in E. coli O157:H7 will correspond with a decrease in the number of foodborne illnesses in humans.
The intestines of cattle are the primary reservoir for E. coli O157:H7 bacteria and other types of E. coli that emit powerful Shiga toxin once ingested by humans. The animals shed the bacteria in feces and it can contaminate butchered meat and many other foods depending on circumstances. Michigan State said in a press release that molecular biologist and epidemiologist Shannon Manning will lead the multi-disciplinary shedding study.
Part of the research goal is to better understand shedding of E. coli from Michigan cattle and dairy cows with the goal of enhancing detection methods and control strategies. Maybe there are farming practices that could reduce colonization of the microbes inside the animals. The research team expects to develop new ideas for direct-fed antimicrobials, vaccines, therapies and other control strategies that can reduce the frequency and level of Shiga toxin E. coli shedding.
