Transcript
From pigs to people The emergence of a new superbug. The discovery of a novel strain of MRSA able to jump from livestock to humans. In this study showing widespread and pervasive staph bacteria contamination of the U.S. meat supply this year or at least in turkey, pork, chicken, and beef. This is the scariest column. Oxacillin, which is in the same class as methicillin. These were of MRSA, methicillin resistant staph areaus, now killing more Americans than AIDS every year in the United States and now found in our retail meat supply.
From an overview of the problem published last year out of the University of Iowa, overall MRSA prevalence in U.S. swine was found to be 11%, and higher in confinement operations. And indeed, testing the workers, those working in confinement operations has a higher prevalence of MRSA in their nostrils. They weren't necessarily picking their nose. Airborne MRSA was found floating around even outside confinement buildings. Because of this, concern has arisen about MRSA as a potential environmental and public health hazard.
