Biosecurity is the practice of preventing pathogens (such as viruses and bacteria) from moving into, out of, or within an area. Keeping pathogens out of areas is considered bio-exclusion. Keeping pathogens in an area, so as to prevent contaminating other areas, is considered bio-containment. Keeping pathogens from moving within an area is considered internal biosecurity. These concepts can be applied anywhere from pen-level to nationally.
Generally, pork producers think about biosecurity at the farm-level. The Canadian Swine Health Board developed a National Swine Farm-Level Biosecurity Standard, which outlines good biosecurity practices that should be implemented on all swine premises. Its main focus is on bio-exclusion, but also considers internal biosecurity, i.e., movement between pens or rooms within a barn, and bio-containment.
Bio-containment is especially important when a farm is dealing with a disease outbreak that other farms in the region are not experiencing. As much as is possible, it is that farm’s ethical responsibility to try to prevent spreading the disease to other farms. Allowing their herd veterinarian to communicate with other veterinarians and Manitoba Pork about the farm’s health status by signing this Sharing of Information Waiver can help all parties limit the spread.
Manitoba Pork also works with provincial authorities, producers, veterinarians, and other industry stakeholders to implement strategies related to regional biosecurity, i.e., keeping diseases out of Manitoba or limiting the spread within Manitoba.
