A Canadian biotech company has developed a vaccine for cattle that prevents them from shedding E. coli in their manure, and its CEO now hopes the Canadian and U.S. governments will help spread the vaccine to combat the threat posed by E. coli contamination in beef.
E. coli illnesses cost the Canadian medical system more than $200 million a year, but vaccinating every cow in the country would cost less than $50 million.
