The cow, aged over 30 months, was imported from the Czech Republic and slaughtered at an Alec Jarrett abattoir in Oldland Common, Bristol, on 1 October.
An FSA statement said: “On 8 October, Alec Jarrett realised there had been an error and acted quickly, preventing the carcase leaving the premises and recalling all associated material that had left the premises. All the recalled product and material still on site has since been disposed of under official supervision.”
None of the affected product has reached the UK food supply added the FSA. A small amount of product has been exported to France and the French authorities have been informed.
BSE testing is mandatory for cattle born in the Czech Republic if slaughtered for human consumption at over 30 months of age.
Cattle aged over 48 months must be BSE-tested before entering the food supply if born in one of the following countries: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Slovenia, Spain, Sweden and the UK.
Cattle aged over 30 months and born in any other country, including the Czech Republic, are only allowed to enter the food supply if they have first tested negative for BSE. If there is no BSE test, all parts of the carcase must be condemned.
