When carrying out surveillance to detect PRRS virus presence in a herd, there are various ways to do so. In recent years, a new and effective method was developed by Spanish veterinarian Jordi Baliellas, attached to the Grup de Sanejament Porci (or Pig Hygiene Group) in Lleida, Spain. He opted for taking tongue tip samples – and that works very satisfactorily. In this first episode of the third Meet the Expert podcast series, Boehringer Ingelheim Animal Health and Pig Progress get to know all there is to know about tongue tip sampling for PRRS virus.
