Does Ecoli harm cows

E. coli, including the species that normally live in the intestines of cattle and cause severe illness in humans, is very susceptible to freezing, intense heat (hence why Hamburgers should be cooked to 145 degrees F before being eaten), most detergents (ie, soap and water), extremes in pH (very acidic or very alkaline), drying out and irradiation. Most of these interventions, with the exception of alkaline application and irradiation) are used to reduce or eliminate E. coli on beef from cows slaughtered in the US.
