Potential effect of cattle diets on the transmission of pathogenic Escherichia coli to humans

Microbes Infect. 2000 Jan;2(1):45-53. doi: 10.1016/s1286-4579(00)00286-0.


Grain feeding seems to promote the growth and acid resistance of Escherichia coli in fattening beef cattle, and acid-resistant E. coli are more likely to survive the human gastric stomach. When cattle were fed hay for only five days, the number and acid resistance of E. coli decreased dramatically.
