> Naturally, there is no proof that superbugs are coming out of the feedlots, because the feedlot owners do not allow any sort of sample collection by scientists. "In the bed of a truck that they parked on county roads adjacent to ten Lubbock-area feed yards, they set up small, generator-powered vacuums. On a number of windy days, they collected upwind and downwind air samples. The results confirmed their suspicions: downwind, they found antibiotics—specifically tetracycline—present at significantly higher levels than in the upwind samples. Yet as they dug deeper, they discovered something even more worrisome. Along with the antibiotics, they found another hitchhiker: remnants of bacteria that had acquired a gene that made them resistant to tetracycline."
