For the first time, a strain of MRSA found in pigs is thought to have passed to humans in the United Kingdom. Scientists have warned that the superbug, methicillin-resistant Staphylococcus aureus, could already be in the food chain because none of those infected works with pigs.

The MRSA strain, ST398, which has been linked to deaths from pneumonia, was first identified in the Netherlands in 2003 and is responsible for 30 percent of the country's human cases of the MRSA infection. Until recently, there were no reported cases in Britain. However, U.K. government laboratories in Scotland have discovered three cases in humans, none of whom work with pigs.

It found the MRSA involved was the strain found in pigs and that there were at least two other cases.
This raises the possibility the MRSA infection is being passed between humans or is reaching consumers buying pork.
