The discovery of horsemeat in products labelled as beef has spread across Europe since last month, prompting product withdrawals, consumer anger and government investigations into the continent's complex food-processing chains.
Swiss-based Nestle, which just last week said its products had not been affected by the scandal, said its tests had found more than 1 percent horse DNA in two products.
"Well we have always eaten horsemeat without a problem but, in this case, it is fraud. It is one thing if I buy it and know that I am buying horse meat, but another if I don't know, also because a horse is too nice to end up in the frying pan," said doctor Alberto Scopietta.
