Sometimes cows get sick just like people do. When that happens, sometimes antibiotics are used to help make them well again. The milk from that cow does not go into the milk supply until she is well again and the antibiotic is no longer in her system. Milk is tested several times before it is bottled. In the rare event that inspectors find any antibiotic residues in a tanker of milk, the entire load is dumped to make sure the milk you drink is safe.
