Tests for horse meat contamination in Bucks carried out by Trading Standards have all returned negative.
Officers visited every butcher in the county between February 18 and March 8 in response to the national horse meat contamination scandal.
In addition, test samples were taken from butchers supplying Buckinghamshire hub kitchens that supply a range of schools in the county.
Results just back from the 63 samples of minced meat, burgers and other products tested by the Public Analyst showed none was found positive for horse DNA. However, Trading Standards Officer David Graby said samples taken from three butchers found minute traces of pork.
These were so minor as to indicate cross-contamination and not deliberate substitution.
Officers will be discussing these findings with the butchers concerned and are reassuring the public these results do not present health risks.
David said: “We’re confident that the residents of Buckinghamshire can be satisfied that their local butcher will provide some of the best quality meat available.
“While we intend to continue to monitor the situation and ensure the quality and reliability of our local traders is maintained, we have no concerns over any of the traders we have tested.’
Buckinghamshire Trading Standards will be contacting all the premises where samples were taken to let them know the outcome.
