Foreign animal diseases of most concern to swine include foot-and-mouth disease (FMD), swine vesicular disease, vesicular stomatitis, hog cholera, African swine fever, and Pseudorabies. The objective is to eradicate any outbreak by preventing the transmission of the infectious agent by slaughter of infected animals and their contacts, pre-emptive slaughter of high-risk herds, quarantine of suspect premises, and more. In the event of a disease outbreak such as FMD, the CFIA must be contacted. Once diagnosed they will carry out slaughter of clinically infected pigs, quarantine and movement control due to the contagiousness of FMD, pre-emptive slaughter of susceptible animal species in herds that have been exposed to the infection, tracing and surveillance of those facilities linked to the FMD infected premise, vaccinate, treat animal products and by-products, decontaminate, monitor wildlife, zone and regionalize, and decide on the actions and restrictions of a declared infected premise. Positive FMD premises are left vacant for a minimum of 21 days after cleaning and disinfecting. Blood samples from the re-stocked herd must be analyzed before shipment. There is a certain protocol that must be followed when considering a vaccination. Canada can re-apply for FMD free status, which would allow the resumption of normal trade 3 months after the last case of FMD.
