Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what the herd incidence rate of Bovine TB has been for each year since 2013.

Official bovine TB statistics for Great Britain, including herd incidence rates, are published on gov.uk and can be found at: https://www.gov.uk/government/collections/bovine-tb.

Herd incidence is defined as the number of new herd incidents (TB-positive herds or TB breakdowns) per 100 herd-years at risk over the time period (in the table above, this is a year). A herd is considered "at risk" for the length of time since its last negative herd test or since the end of its last TB incident. Thus, this measure gives the average number of new incidents for every 100 unrestricted herds undergoing TB surveillance over the time period.
