Dorothy Farrell, a columnist for something called Pipe Dream, writes that, “As I grew up, I discovered that most hamburgers come from a place called a concentrated animal feeding operation (CAFO). Many of those animals do not enjoy simple luxuries in life, like sunshine or freedom to walk. I learned that cows are meant to eat grass, and that the only outbreaks of E. coli are cultured in cows that are fed corn. “

This is nonsense. All ruminants are the natural reservoir for shiga-toxin producing E. coli. She didn’t learn much.
