Why do farmers treat cows with antibiotics?
Sometimes, cows get sick, just as some humans do. Without proper medical care, the cows would become seriously ill or die. So, it is simply humane to treat them – and make them well again with medications prescribed by veterinarians. If a cow is treated with antibiotics, she is kept in a separate pen or milking group. The milk from that cow is disposed of, and does not reach the food supply.
