The Animal and Plant Agency (APHA) has now expanded the use of rapid PCR testing of post-mortem tissue samples from animals with suspected bovine TB infection, following the success of its initial rollout. The new method reduces the time taken for APHA laboratories to report results to livestock keepers from up to 22 weeks to approximately 3 weeks.     For farmers, this new tool will reduce the stress of waiting for results to be delivered and provide earlier certainty about the presence of bovine TB in their herd. For a small proportion of samples the PCR test may not produce a definitive result. When this occurs, livestock keepers will be informed that additional testing could take up to nine weeks.
