Management of pandemic H1N1 in swine herds The Canadian Food Inspection Agency (CFIA), in collaboration with stakeholders, trading partners, and the public and animal health communities, has refined its approach to managing cases of the pandemic H1N1 2009 virus in swine.
This approach is consistent with the recommendations of the World Organisation for Animal Health (OIE), and is based on research and observations made since the virus was first detected in swine, which indicate:
• There is no food safety risk associated with the virus;
• There is no evidence at this time that animals are playing a significant role in the spread of the virus in the general human population; and,
• The virus does not behave any differently in pigs from other influenza viruses commonly detected in swine herds.
Based on this knowledge and information, the CFIA will not quarantine herds. Affected animals will be managed using the same veterinary management and biosecurity practices employed for other swine influenza viruses. This includes limiting opportunities for virus to spread to susceptible animals. Canada’s slaughter system contains multiple inspection points to ensure that only healthy animals enter the food supply.
All herds in which the virus is detected will be monitored to verify that infected animals recover. In addition, surveillance for the presence of H1N1 in swine will continue, to detect any changes in how the virus affects swine and to identify any changes in the structure of the virus. Producers are encouraged to reinforce biosecurity measures at their facilities.
This approach is supported by Provincial and Territorial authorities and the Public Health Agency of Canada.
