Once TB-infected cattle have been found, milk and movement restrictions come into force

TB-infected cattle can be found at:

  1. A skin test
  2. An interferon-gamma blood test
  3. Routine meat inspection at the slaughterhouse when animals are sent to slaughter
  4. A post-mortem inspection undertaken somewhere else e.g. at a hunt kennel or on farm
  5. Rarely, clinical cases where a live animal is showing signs suspicious of TB
TB can be found in several ways

Reactors found at a skin test

The flow diagram below summarises what happens when one or more TB reactors are found at a skin test. The number of herd tests needed and use of the interferon-gamma (‘gamma’) blood test depends on which TB risk area the herd is located in, and the results of skin testing and post mortem inspection for any reactors found. To check which TB risk area your herd is located in, take a look at our interactive risk map. To find out more about gamma testing, access information on the TB hub.

Slaughterhouse cases

For slaughterhouses cases, the process is slightly different as shown in the following flow diagram.

Movement restrictions

If TB is suspected or confirmed in a cattle herd, movement restrictions are automatically immediately applied to the herd.

Milk restrictions

Milk restrictions are also applied immediately if TB is suspected or confirmed in a cattle herd.
