Meat from a second offspring of a cloned cow has entered the food chain, the Food Standards Agency said last night.
The FSA said it had traced all of the calves born in the UK from eight embryos from a cloned cow in the US. It confirmed meat from a second bull, Parable, had entered the food chain. The animal was born in May 2007 and slaughtered on May 5, 2010.
This follows confirmation on Tuesday that meat from another of the bulls, Dundee Paratrooper, entered the food chain in 2009.
The FSA said meat from both animals will have been eaten, but stressed there was no evidence of a safety risk.
On Tuesday, the FSA said a third bull, Dundee Perfect, was slaughtered on July 27 this year and its meat prevented from entering the food chain.
The FSA also confirmed last night that one of the four cows, Dundee Paradise, remained part of a dairy herd on a UK farm, but there was no evidence its milk had entered the food chain.
The agency believed two other cows were being kept as part of dairy herds but it had been unable to confirm if their milk had entered the food chain.
Of the eight calves, four of each sex, one male and one female died at around one-month-old. No meat or products from the animal had entered the food chain.
The FSA said it was trying to trace offspring from the eight animals, but added that they would be too young to be milked or used for breeding.
An investigation was launched in the wake of claims that a British farmer had admitted using milk in his daily production without labelling it as from the offspring of a cloned cow.
Under European law, foodstuffs including milk produced from cloned animals must pass a safety evaluation.
