Canadian biotech scientists are researching a way to bioengineer cattle feed so that it contains a natural antibiotic that would eliminate the E. coli 0157:H7 bacteria from cows' digestive system. According to a report in the Globe and Mail, a Canadian government laboratory, the National Research Council, and a private agribusiness company, DowAgroSciences Canada, are working to introduce a gene that produces an antibody preventing O157 from multiplying into something cows naturally eat, such as corn.
