One in 10 eight-year-olds do not realise that pork chops come from pigs. And some even believe that cows lay eggs.
A new survey also reveals that nearly two out of 10 children had no idea where yoghurt comes from. Eight per cent of youngsters did not realise that beefburgers come from cows - compared to thre per cent who live in the countryside. Two per cent of urban kids thought cows produce eggs.
But all children knew that milk comes from cows. The Dairy Farmers of Britain asked more than 1,000 children aged eight to 15 where they thought eggs, cheese and yoghurt, bacon, pork chops and beefburgers came from.
A spokesman said: "A significant proportion, particularly those living in the city, are unaware of the process involved in making their food."
