Ever wondered how the TB test works and why we have to do them every year?Every year farmers and vets go through the pain and sometimes misery of doing TB tests on a herd, but it’s all for a good reason. We don’t think about the good this preventive measure does because many of us have never seen a symptomatic animal. To help answer some of the questions farmers have asked about the TB and the TB test, ICBF with help from DAFM has put together a TB FAQ sheet on the Health and Disease page. The TB page includes answers on what causes TB, what the symptoms of TB are, why you’ve most likely never seen an animal with symptoms, why it seems to just pop up out of the blue, and a few others. Below is a set of cartoons that we made up to explain how the TB test works. For more information and for answers to the questions above Click here to view the rest of the TB page:
