Tests on milk from several different farms across the U.K. have turned up evidence for a new strain of MRSA — bacteria which have evolved resistance to common antibiotics. As long as the milk is properly pasteurized, it poses no threat to consumers, but anyone working directly with the animals bears a small risk of infection. According to The Independent,"The disclosure comes amid growing concern over the use of modern antibiotics on British farms, driven by price pressure imposed by the big supermarket chains. Intensive farming with thousands of animals raised in cramped conditions means infections spread faster and the need for antibiotics is consequently greater. Three classes of antibiotics rated as 'critically important to human medicine' by the World Health Organization – cephalosporins, fluoroquinolones and macrolides – have increased in use in the animal population by eightfold in the last decade."
