The Superbug in Your Supermarket

with 2 comments

superbug_supermarketA potentially deadly new strain of anti-biotic-resistant microbes may be widespread in our food supply.  MRSA, or methicillin-resistant Staphylococcus aureus, is a form of staph bacteria that resists antibiotics (including methicillin), making it hard to treat, even lethal.  Industrial agriculture is now a potent source of these infections.

from an August article by  Stephanie Woodard in Prevention magazine:

” Are You At Risk?

You’ve probably heard of people contracting certain strains of MRSA in hospitals, where it causes many illnesses: postsurgical infections, pneumonia, bacteremia, and more. Others encounter different types of the bug in community centers such as gyms, where skin contact occurs and items like sports equipment are shared; this form causes skin infections that may become systemic and turn lethal.

Then in 2008, a new source and strain of MRSA emerged in the United States. Researcher Tara Smith, PhD, an assistant professor of epidemiology at the University of Iowa, studied two large Midwestern hog farms and found the strain, ST398, in 45% of farmers and 49% of pigs. The startling discovery– and the close connection between animal health and our own that it implied–caused widespread publicity and much official hand-wringing. To date, though, the government has yet to put a comprehensive MRSA inspection process in place, let alone fix our problematic meat-production system.

You may not have the same close contact with meat that a processing plant worker has, but scientists warn there is reason for concern: Most of us handle meat daily, as we bread chicken cutlets, trim fat from pork, or form chopped beef into burgers. Cooking does kill the microbe, but MRSA thrives on skin, so you can contract it by touching infected raw meat when you have a cut on your hand, explains Stuart Levy, MD, a Tufts University professor of microbiology and medicine. MRSA also flourishes in nasal passages, so touching your nose after touching meat gives the bug another way into your body, adds Smith.”

Human Health, Antibiotics and Industrial Farms

with 5 comments

chickenfeedH.R. 1549, the Preservation of Antibiotics For Medical Treatment Act of 2009  now under consideration by the House, would limit the amount of antibiotics that can be used on factory animal farms.  “The farm lobby’s opposition makes its passage unlikely,” The New York Times reported Monday. 

Industrial agriculture has adopted many practices that put public health at risk.  Factory farms routinely feed animals antibiotics to off-set crowding and bad sanitation.
