Researchers recently published in The Lancet Infectious Diseases the discovery of a new strain of the bacteria methicillin-resistant Staphylococcus aureus (MRSA). The antibiotic-resistant strain was discovered while scientists were studying udder infections in British cows. In addition, the researchers have found the strains in humans in Scotland, England, Denmark, Ireland, and Germany. Mark Holmes of Cambridge University and his colleagues stressed that while pasteurized milk is still safe for consumers, they warn that unpasteurized dairy could be tainted. MRSA is commonly the strain of bacteria that commonly causes staph infections, but this newfound version is resistant to antibiotics.
