Chicken litter harbors agents that generate antibiotic multi-resistance, according to UGA study
... in the 1950s, researchers initially believed that simply restricting the use of antibiotics on farms could reduce the prevalence of antibiotic resistance among humans, but it hasn't been that easy.

"Remarkably, when the cells were simply grown in regular dishes in the lab, RhoA's activation or inactivation overrode signals usually used to direct their growth toward fat or bone," says McBeath.
