Crohn’s suspect tougher than thought

TOUGHER pasteurisation standards are not enough to stop a harmful bug found in milk from multiplying, scientists have admitted.

John Hermon-Taylor of St Georges in London has linked the bacterium mycobacterium avium subspecies paratuberculosis (MAP) to Crohns disease.

He believes the inflammatory bowel condition can be contracted through drinking milk which contains MAP.

In the past he claimed that increasing pasteurisation times from would almost certainly render the bug unable to multiply.

But researchers in Belfast have shown that the bug can survive more stringent pasteurisation, reports the BBC Radio 4 Farming Today programme.

Prof Hermon-Taylor said: “Weve got to go back to the drawing board and do research which finds out the set of circumstances which kill the organism and are industrially applicable.”

However, Prof Hermon-Taylor has received better news with the announcement of a grant from the Action Research charity.

He says this will help him work towards developing a DNA vaccine to treat humans with Crohns Disease.

However, he admitted little had been done to tackle the disease in animals.
