London - The supermarket giant Tesco yesterday took all its organic mushrooms off it shelves in Britain after routine tests showed the "possible presence" of the deadly E.coli virus.
Customers were warned not to eat organic mushrooms bought from the store after a preliminary test found the possibility of the E.coli O157 in a 200g pack with the display date of May 10th. Tesco said it was a "strong possibility" that Belgian manure infected the mushrooms, which came from a supplier in Northern Ireland.
