Giving Antibiotics to Animals Can Harm People
An international team of scientists says it has proof the life-threatening MRSA superbug got its resistance from farm animals that were injected with antibiotics.
Researchers say that MRSA began as a basic staph infection in people and then migrated to food animals like cows, pigs and turkeys.
There the bacteria developed a resistance to some antibiotics before migrating back to people.
Now the drug resistant bacteria is hard to treat in people.
