C' EST UN PLAIDOYER SCIENTIFIQUE.... CONTRE L' UTILISATION DE TROP D' ANTIBIOTIQUES DANS L' ÉLEVAGE INDUSTRIEL .. MAIS AVANT D' ETRE ENTENDU PAR LE BIG ELEVAGE BUSINESS ..
CETTE ETUDE DATE DE JUILLET 2013 ET IL SERAIT INTERESSANT DE VOIR COMMENT CELA A EVOLUE EN PRESQUE DEUX ANS..
Folks sounding alarm bells over the continued widespread use of
antibiotics in industrial animal production recently got some scientific
backup to support their case.
Ironically, it may have been missed by
those of you chowing down on hotdogs and BBQ chicken this past Fourth of
A group of scientists swabbed the noses of two distinct groups of
North Carolina hog farm workers looking for antibiotic-resistant
Staphylococcus aureus. One group worked in a conventional industrial hog
farm; the other in an antibiotic-free operation. What’d they find? According to the new study,
just over 40 percent of both groups carried staph bacteria—but several
of those who worked in the conventional industrial pig farm also carried
something called ST398, also known as pig MRSA.
What’s the difference between the bacteria, and why does it matter?
Maryn McKenna, author of SuperBug, covers the new study for Wired, writing,
“The question of whether livestock production’s use of antibiotics
causes antibiotic-resistant bacteria to move into the wider world is
much argued-over, and pig MRSA, or ST398 to be polite, is crucial to
that dispute. That’s because, unlike most resistant bacteria, it has a
genetic signature that makes an inarguable link back to farm drug use.”
Gail Hansen, senior officer for Pew Charitable Trusts campaign on
human health and industrial farming, says that we can find Staph
bacteria on the general population, but the fingerprint of the ST398
brings it straight back to agriculture.
“We’re seeing that this livestock-associated strain of Staphylococcus
aureus is multi-drug-resistant and can go from person-to-person. It can
leave the farm, and if it leaves the farm, it goes everywhere. It
doesn’t stop because you live in the city or just because you don’t eat
meat,” she tells TakePart.
Chris Heany, one
of the study’s authors and assistant professor of environmental health
sciences and epidemiology at Johns Hopkins Bloomberg School of Public
Health, says when they looked at Staphylococcus aureus, the
livestock-associated strains were only present in the industrial hog
operation, not the antibiotic-free environment.
“That’s the key thing. What’s remarkable is while everyone in the
study had direct or indirect contact with livestock, we only observed
drug-resistant [bacteria] with multiple genetic characteristics in the
industrial group. That’s interesting, and builds on the work being done
by Tara Smith at the University of Iowa,” Heany tells us.
According to The New York Times’ Mark
Bittman, Smith’s work showed evidence that MRSA was indeed moving from
pigs to humans in Iowa and Illinois. And, like North Carolina, Iowa and
Illinois are among the top large-scale pork-producing states.
Worry of antibiotic use in animal production isn’t new. As we told you back in February,
even the U.S. Food and Drug Administration is growing concerned about
antibiotic resistance stemming from livestock production. In 2011, 30
million pounds of antibiotics were sold for use in beef, pork and
poultry production. That’s four times the amount sold to humans
who were sick—a stunning statistic, especially given our antibiotic
arsenal that keeps us humans healthy is relatively small to begin with.
Will a study like this move the U.S. meat industry away from regular
antibiotic use? Probably not in the immediate future, but it adds
particularly compelling information to this very important conversation.
