Bovine tuberculosis (TB) is a devastating disease of cattle and a major challenge facing large parts of the UK cattle farming industry today.
Although the disease is controlled in most developed countries, the complete eradication of TB worldwide is made difficult by wildlife reservoirs.
TB can also affect other mammals, including humans, badgers, deer, goats, pigs, dogs and cats.
Scotland achieved Officially Tuberculosis Free Status (OTF) in September 2009 under the EU Council Directive 64/432/EEC. OTF status is recognition of the relatively low and stable incidence of TB found in Scottish herds. This does not mean that Scotland has no cases of bovine tuberculosis, but recognises that we have relatively few cases, below the threshold for that designation.
After leaving the EU, Scotland’s OTF status is now recognised under the EU 2021/404. Under this legislation, Annex II, Part 1 provides an animal health guarantee for Scotland, which states that ‘The Union has recognised freedom from infection with Mycobacterium tuberculosis complex (M. bovis, M. caprae, M. tuberculosis) of the third country, territory or zone as regards the specific species of animals referred to in column 3 in accordance with Article 10 of Delegated Regulation (EU) 2020/692’.
Following EU Exit, third countries, including the territories within the UK, will be listed in a new implementing regulation in accordance with Article 230(1) of Regulation (EU) 2016/429.
Human health implications
Bovine TB is a zoonotic disease which means it can be passed from infected animals to people, causing an illness similar to human TB. However, the risk of people contracting TB from cattle in Scotland is considered to be very low, and there are no recent cases in humans in Scotland linked to cattle infection
Biosecurity is about being aware of the ways disease can spread and taking every practical measure to minimise the risk of disease spreading. The advice details practical things you can do on your farm to help prevent the introduction and spread of bovine TB to and from your animals.
