Listen to this episode of the Topigs Norsvin podcast and learn how to take biosecurity on your farm to the next level. Heloiza Irtes, Regional Veterinary Manager LATAM and Mitch Christensen, Chief Veterinary Officer discuss a key element of modern state-of-the-art biosecurity: a layered approach. If one layer in the defence fails, another layer will block the entry of a disease. This layered approach can be applied, for example, when introducing new animals or for visitor access.
