A new strain of methicillin-resistant
Staphylococcus aureus (MRSA) 'superbug' has been found in cows milk in UK by researchers
at Cambridge University. Experts insist there is no overall threat to the
safety of milk sold in shops because any kind of MRSA in dairy products is
destroyed by the heat used in the process of pasteurization.
According to environmental experts the new MRSA strain has
emerged due to over-use of antibiotics by dairy farmers.
The Soil Association has called for a complete ban on routine use of
antibiotics in livestock because of fears they may promote drug-resistant
Subsequent research suggested that the strain was also found
in humans. Scientists feel the need for further
research to ascertain if humans were spreading the bug to cows or vice versa.
