DNA pigs

Legs of Spain's top Jamon Iberico now come with their own DNA certificate to prove they are the purest as well as the world's most expensive hams. Spain's top producer has enlisted the help of scientists to prove that his pigs are of the purebred Spanish variety and not crossed with lesser British or American breeds. Gourmets from across the globe are eagerly waiting for the hams, which will hit the market next month. Only 100 legs from the "prince of pigs" are available and with a starting price of 1,500 euros (£1,380) each, they have been dubbed by foodies as the "RollsRoyce of Spanish ham".
