Antibiotic Resistance Transfer Less than Reported


According to an article from, British researchers have now put some science behind the debate of animal antibiotic use and human resistance.  They quote a recent study (READ STUDY HERE) as saying that policies to restrict antibiotic use in animals are “simplistic.” reports that:

Researchers at the University of Glasgow used long-term surveillance data of Salmonella typhimurium DT104 from humans and animals in Scotland. They found that just 22 out of the 5,200 isolates studied were resistant in both animals and humans. Of those 22, just five were identified first in the animal isolates, suggesting that animals were an unlikely source of antibiotic resistance in humans.

Earlier this month, the U.S. Food and Drug Administration announced that, as of April 5, they will be restricting certain livestock uses of the cephalosporin class of antimicrobials in an attempt to protect him resistance.  For more details on those restrictions, read “FDA Initiates Partial Animal Antibiotic Ban.”
