The suspected cases were spotted by vets on Wednesday night (19 March) after two pigs showed symptoms of the disease at a slaughterhouse in the south of England.
The pigs had been transported from a major producer in Aberdeenshire. The unit has been visited by officials from the Animal Health and Veterinary Laboratories. It will remain under restriction until the results of a second test are delivered on Friday afternoon (21 March).
A statement by sector body the British Pig Executive praised the initiative taken by the veterinary officials and called for producers to be watchful.
This is the second swine fever alert in the past six months and it emphasises the importance of continued vigilance by producers and abattoirs.
