Authorities have been quick to calm fears prompted by the outbreak of Bovine spongiform encephalopathy (BSE) - more widely-known as mad cow disease - after movement restrictions were placed on animals at an unidentified farm in Aberdeenshire, meaning the animals can not be moved to other farms. Rural Economy Secretary Fergus Ewing has said that a movement ban was now in place on the farm, which remains unnamed. The animal did not enter the human food chain and the Food Standards Scotland authority confirmed there was "no risk to human health" resulting from the isolated case, the statement said. Officials also stressed that consumers should not yet be anxious by the case because the disease did not enter the human food chain. The finding of the disease is a "disappointment", said Scotland's Chief Veterinary Officer, Sheila Voas. "We are working closely with the Animal and Plant Health Agency to answer this question, and in the meantime, I would urge any farmer who has concerns to immediately seek veterinary advice". Scottish officials said the case does not pose a threat to humans. In 1996, it became clear the disease can be transmitted to humans in the form of Creutzfeldt-Jakob disease. "The Animal Health Agency (APHA) is investigating the source of the outbreak". The Scottish Government statement added: "In addition to the measures we have in place for fallen stock and animal feed, there is a strict control regime to protect consumers". The case was discovered during routine tests on a farm animal that recently died.
