The research article did a detailed DNA analysis on the Staph bacteria and it's clear that it’s not only a newly recognized MRSA, but that this unique strain was found in both cattle and humans. So far, it has only been found in the UK and Denmark. Much of the article was focused on the important implications for physicians who are trying to confirm a case of MRSA in a patient. It was estimated in the article, however, that approximately 2.8% of dairy farms may have this strain of Staph.
This important research article has triggered a number if 'news' items in publications like The Guardian, The Telegraph or The Independent, or online news aggregators like Natural Society or TopNews. Various blogs have jumped on the 'cow to human' claim and the 'Twitterverse' is rampant with links to this claim.
Only Reuters correctly indicated that the scientists did not know if humans were giving the MRSA bug to cows or if cows were a reservoir for humans.
The British group, Soil Association, is often referred to as the leading organization representing organic farming in the UK. They have published a policy paper on this topic that lists the limited evidence that the movement of the bacteria was from cow to humans.
