August 21, 2013 Beta agonists, a class of drugs widely fed to cattle and hogs to make them put on weight faster, are coming under increasing scrutiny. Reports suggest animals fed these drugs can seem reluctant to move — lethargic, unable to walk properly — and may die more often, too.

July 11, 2013 Farmers give antibiotics routinely to pigs, beef cattle and poultry. They say the drugs help keep animals healthy and get them to market faster. Others say this practice practically guarantees that bacteria will develop resistance to these antibiotics more quickly, endangering human lives and the long-term viability of the drugs.

April 17, 2013 A new analysis of government data finds that antibiotic-resistant bacteria that cause human illness were widespread in supermarket meat samples tested. The implications are significant: that the bacteria had become resistant to antibiotics back at the farm because farmers were overusing them.
