There’s a new study that says antibiotics used to treat livestock and antibiotic-resistant genes that pose a threat to humans can be carried by the wind from large livestock operations reports Politico.

Researchers at the Institute of Environmental and Human Health at Texas Tech University say they found six veterinary antibiotics in dust samples downwind from 10 large beef cattle feedlots in Texas. 

The long, slow decline of the U.S. sheep industry

Over the last 20 years, the number of sheep in this country has been cut in half. In fact, the number has been declining since the late 1940s, when the American sheep industry hit its peak. Today, the domestic sheep herd is one-tenth the size it was during World War II.


Tyson Foods, Inc., announced last week that it will soon suspend purchases of cattle that had been treated with a controversial drug, citing animal welfare concerns.

But many in the industry wonder if the real reason is not about cattle, but rather the battle for sales in other countries, where using drugs for meat production is banned.

“I really do think this is more a marketing ploy from Tyson to raise some awareness so they can garner some export business from our overseas export partners,” said Dan Norcini, an independent commodities broker.
