Highly pathogenic avian influenza

Avian influenza (AI), commonly known as "bird flu", is a contagious viral infection that can affect several species of food producing birds as well as pet birds and wild birds. British Columbia has been experiencing repeated outbreaks of highly-pathogenic avian influenza (HPAI) H5N1 in poultry (a form of the virus that causes serious illness and death) since the virus was first introduced into the province in April 2022. This same virus is circulating throughout North America and causing outbreaks in other provinces and states.

More information on the ministry response to AI can be found here Avian influenza (AI) -  Province of British Columbia (gov.bc.ca)

AI is a federally regulated disease and the Canadian Food Inspection Agency (CFIA) leads the response. See the CFIA website for more information on the status of ongoing AI outbreaks and response by province.

Commercial chicken and turkey to remind indoors: General order removed

Effective June 17, 2025, the Chief Veterinarian has removed General Order AIV 2024-01, which required persons responsible for chickens and turkeys in operations regulated by one of the provincial boards or commissions listed below to keep their poultry indoors.

All persons responsible for chickens and turkeys in operations regulated by one of the following:

  1. BC Broiler Hatching Egg Commission
  2. BC Chicken Marketing Board
  3. BC Egg Marketing Board
  4. BC Turkey Marketing Board (each a “Board or Commission”)

and who hold quota from their relevant Marketing Board or Commission were subject to this order.

Diligence in applying biosecurity measures remains the most important tool in preventing poultry flocks from contracting avian influenza. It is essential that producers continue to maintain on-farm biosecurity at all times, even after the lifting of the order.

 

Commingling of poultry in the Lower Mainland general order removed

Effective April 7, 2025, the Chief Veterinarian has removed General Order AIV 2024-02 (PDF, 281 KB), which prohibits commingling of poultry in the Lower Mainland. 

Diligence in applying biosecurity measures remains the most important tool in preventing poultry flocks from contracting avian influenza. It is essential that poultry owners and event organizers continue to maintain on-farm biosecurity and practice biosecurity at poultry events at all times, even after the lifting of the order.

 

B.C. wildlife HPAI Surveillance Dashboard (HPAI Detections in Wildlife and Environmental Samples) 

Migratory wild birds, particularly waterfowl species, are the main source of HPAI for poultry. The BC Ministry of Agriculture and Food conducts surveillance for HPAI in wild birds to assess the risk of infection in domestic poultry. Although relatively infrequent, AI can also cross the species barrier and infect mammals. The current surveillance program detects HPAI viruses by collecting and testing wild birds and mammals that are found dead on the landscape as well as environmental samples. The results of this program are summarized in the dashboard below.

 HPAI Surveillance Dashboard

Note:

  • HPAI H5 detections include both samples that have been confirmed as HPAI H5N1 clade 2.3.4.4b through sequencing or are presumed to be HPAI H5 the basis of a positive H5 polymerase chain reaction (PCR) test.
  • Reporting timeline on dashboard may be extended due to the time taken for sample collection, sample processing, submission, and testing. 
    • Wild bird results: ~14 days from the sample collection date 
    • Sediment results from wetland: ~21 days from the sample collection date

Chronic Wasting Disease

Chronic Wasting Disease (CWD) is a fatal infection that affects species in the deer family (cervids) such as mule deer, white-tailed deer, elk, moose and caribou. CWD is not a naturally occurring disease and can lead to declines in cervid populations. There is no vaccine or treatment and the disease is always fatal.

BC’s first detection of CWD was confirmed in the Kootenay region in January 2024. In accordance with the Surveillance and Response Plan for CWD in B.C., the Ministry of Water, Land and Resource Stewardship is the lead agency on CWD management. As part of the response, B.C.’s Chief Veterinarian has put orders in place to reduce risk of dissemination of infected materials by human activity, in order to reduce risk of disease spread to non-infected cervid populations.

Cervids found dead in areas of southeast BC must be submitted for CWD testing and require special disposal.

Effective September 20th, 2024, the Chief Veterinarian issued General Order CWD2024-002 (PDF, 1.8 MB), which replaces General Order CWD2024-001 (PDF, 255 KB).

All persons who collect found dead cervids, or parts of found dead cervids (including deer, elk, moose, and caribou) (“Collected Cervids”), in Wildlife Management Units 4-1 to 4-8 and 4-20 to 4-25 inclusive (“the Area”) must take the following actions, and must comply with the following prohibitions:

  • Samples from any Collected Cervid originating within the Area must be submitted to a government testing site or drop-off location for testing in accordance with Chronic Wasting Disease Surveillance and Testing - Province of British Columbia (gov.bc.ca)
  • The remaining, untested portions of any Collected Cervid originating from within the Area must not be removed from the Area or used for any purpose, and may only be either:
    • transported to a Designated Disposal Site (defined below) for disposal, or
    • transported to a storage location and held in a secure, leak-proof container, freezer or cooler inside the Area 

until testing is complete and the result is confirmed negative for the presence of CWD

  • Portions of any Collected Cervid which tests positive for CWD must be held in a secure, leak-proof storage container until further instructions are received from the Ministry of Water, Land and Resource Stewardship

Each of the following is a “Designated Disposal Site”:

  • Cranbrook Regional District Landfill
  • Creston Landfill
  • Ootischenia (Castlegar) Landfill
  • Ministry of Transportation and Infrastructure secure disposal sites or
  • The government collection site at 205 Industrial Road G, Cranbrook, B.C.

Whirling disease 

Whirling disease is an infectious disease of finfish such as trout and salmon. It is caused by a parasite called Myxobolus cerebralis.

There is no treatment for whirling disease. Once introduced, the elimination of the parasite in wild finfish populations is not usually possible.

Whirling disease is not a health risk for humans or pets. The parasite that causes whirling disease does not affect humans or animals other than finfish. There is no risk associated with swimming or eating fish caught from infected waters.

Whirling disease is a reportable disease in respect of finfish under Section 5(h) of the Reportable and Notifiable Disease Regulation under British Columbia’s Animal Health Act. Whirling disease is a federally regulated disease, and the Canadian Food Inspection Agency (CFIA) is the lead agency. Provincially, the Ministry of Water, Land and Resource Stewardship is the lead agency.
