Superbugs Go Airborne, Triggering Fears of Global Epidemic

Antibiotic-resistant genes, that evolved in the crowded atmosphere of Texas commercial cattle ranches, have gone airborne and are now capable of "travelling for long distances."

Researchers at Texas Tech University studied the particulate matter blown up over the Texas Panhandle and South Plains from the large feedlots where 5 million beef cattle are raised for slaughter yearly.

They found that air downwind from the feedlots contained significantly more antibiotic-resistant bacteria DNA that air upwind, they concluded in their paper published in Environmental Health Perspectives.
