THE secret of how to beat a deadly food poisoning bug may lie in Scotland's farmyards. Scientists have found that up to a fifth of Scottish farmers are immune to infection with E coli, which is spread mainly through cattle dung.
In a previous study of farmers in England and Wales, the researchers found that around three per cent had immunity to E coli 0157.
But in the Grampian region - thought to have one of the highest rates of the infection in the world - results have so far suggested a much higher rate of antibodies.
Low level expose giving immunity or Darwin at work? Knowing the state of some farmyards I am not sure it isn't the latter.
