There have been many concerns raised in recent years about the overuse of antibiotics on farms, but the effect such uses have on human health is not fully understood. Researchers at Texas Tech University are now suggesting that airborne dust could be a pathway for antibiotic-resistance bacteria to travel from feedlots to human environments. Scientists…

New research finds that E. coli O157:H7 can spread more than a tenth of a mile downwind from a cattle feedlot onto nearby produce. In the study, first author Elaine D. Berry of the U.S. Department of Agriculture’s U.S. Meat Animal Research Center and her colleagues sampled leafy greens growing in nine plots (three each…

The year before USDA’s new groundbreaking non-O157 E. coli policy went into effect, the agency went back to America’s feedlots to find out just how prevalent six new strains were at the source. The 2011 study into the prevalence of Escherichia coli O-Types and Shiga-Toxin genes in fecal samples from feedlots is being published in…

Environmental groups and the U.S. Environmental Protection Agency reached a settlement yesterday requiring the agency to propose a rule on greater information gathering on factory farms, otherwise known as concentrated animal feeding operations (CAFOs). The rule, to be proposed within 12 months, would require the 20,000 or so domestic factory farms to report information like …

Cattle hides are more likely to be contaminated with E. coli at the feedlot than at the slaughterhouse and transport and lairage do not increase the number or isolation rate of E. coli O157 according to a recent study.

The study, conducted by Australian researchers and published in Foodborne Pathogens and Disease, conflicts with …
