Avian influenza in wild birds
Highly pathogenic avian influenza
Avian influenza virus (AIV) is a contagious viral infection that can affect domestic and wild birds throughout the world. Many strains occur naturally in wild birds and circulate in migratory populations. AIV is designated highly pathogenic avian influenza (HPAI) when it has characteristics that cause mass disease and mortality in infected poultry.
There have been no human cases of avian influenza resulting from exposure to wild birds in North America.

Signs of a sick bird
Signs of avian flu include:
- lack of energy or movement
- nervousness, tremors or lack of coordination
- swelling around the head, neck and eyes
- coughing, gasping for air or sneezing
- diarrhea or
- sudden death
Reporting sick or dead birds
As a general guideline, do not touch live, sick or dead wild birds.
Always report sick or dead birds to the relevant authority indicated below. Reporting bird carcasses helps to track avian influenza and allows the provincial/territorial authority to provide advice. In certain cases, local authorities may recommend that the public safely disposes of dead birds. The disposal of bird carcasses must be done in a sanitary manner by following guidance provided by the relevant authority. The Public Health Agency of Canada recommends wearing gloves or using a doubled plastic bag if you must handle wild bird carcasses, and avoiding contact with blood, body fluids and feces. You should then wash your hands thoroughly with soap and warm water or use hand sanitizer.

Feeding wild birds in your backyard
To minimize the risk of transmission of HPAI, do not handle or feed any wild bird by hand. Feeding encourages wild birds to congregate around food sources and can increase the probability of transmission among wild birds, both within and among species.
The use of bird feeders is still safe but they should be removed from areas that are open to poultry and other domestic animals. If you care for poultry, prevent contact between wild birds and poultry by removing exterior/outdoor sources of food, water and shelter that attract wild birds.
Backyard bird feeders and baths should be cleaned regularly using a solution of 25 millilitres of household bleach (sodium hypochlorite, 5%-6%) and 2 litres of water. Ensure they are well rinsed and dried before re-use.
Protecting domestic and captive birds
Domestic birds are at risk of contracting viruses like avian influenza, in particular if they have access to the outdoors and ponds or bodies of water used by wild birds. Owners are urged to take an active role in protecting their flocks by employing strict biosecurity measures on their property including minimizing contact between wild birds and their small flocks.

Information for migratory bird permit holders
Wildlife rehabilitation centres, aviculturists, zoos, and other migratory bird permit holders should take measures to limit interactions with wild birds and improve biosecurity during an HPAI outbreak.
To request biosecurity guidance documents for wildlife rehabilitation centres, aviculturists, zoos and other migratory bird permit holders, please contact your regional permitting office.
Provincially permitted wildlife rehabilitation facilities should inquire with provincial permitting offices for guidance.
The Public Health Agency of Canada website offers guidance on human health considerations: Precautions for bird banders, aviculturists and wildlife rehabilitation centres.
Decontamination protocols following contact with wild birds or wild bird droppings
Thoroughly wash your hands with soap and water before and after completing these steps outside or in a well-ventilated room using protective eyewear and gloves:
- remove all organic material from footwear and other contaminated articles of clothing or equipment
- scrub again, using a solution of 25 millilitres of household bleach (sodium hypochlorite, 5%-6%) and 2 litres of water.
- let stand until the surface is dry
- scrub with hot water and common household disinfectant following the label directions.

Information for hunters and egg harvesters
Migratory birds and their eggs are federally protected under the Migratory Birds Regulations (MBRs). When you are planning activities that might affect migratory birds, it is your responsibility to know which sections of the MBRs apply. Provincial/territorial laws and regulations pertaining to migratory birds and harvest activities should also be reviewed where they apply.
There are temporary restrictions on importing or exporting harvested meat from migratory game birds hunted in areas affected by HPAI. For more information, consult the CFIA – Highly Pathogenic Avian Influenza Zones, Permits and conditions needed for movement control, CFIA - Notice to industry: Restriction on imports of live birds, bird products and by-products from states affected by Highly Pathogenic Avian Influenza in the United States, and Imports: Animal and Animal Products (United States Department of Agriculture, available in English only).
While there is no documented evidence of humans getting avian influenza from handling or consuming game meat or eggs that have been fully cooked, it is recommended to follow these guidelines to reduce any risk of exposure to avian influenza and other pathogens:
- cook game meat thoroughly, to an internal temperature of approximately 74°C (165° F)
- follow safe food handling practices such as hand washing and keeping game products separate from other food products to avoid cross-contamination
- do not eat, drink, or smoke while handling raw game products
- thoroughly clean contaminated surfaces on tools, work areas, and clothing.
Follow these guidelines when you harvest eggs:
- avoid harvesting eggs in areas where apparently sick or dead birds are found
- practice good hand hygiene while harvesting and handling eggs
- wear gloves (e.g. vinyl, latex, nitrile, rubber) when handling eggs if possible
- always wash your hands before and after handling eggs, using hand sanitizer when soap and water aren’t available
- avoid touching your face or rubbing your eyes
- don’t eat, drink or smoke when handling eggs
- try to collect clean eggs only; avoid collecting cracked or dirty eggs
- eggs should be dry cleaned only
- rub dirt and debris off of eggs with a clean and dry paper towel, cloth, or brush
- washing or soaking eggs with water can affect the eggshell and allow germs to enter the egg
- always wash all egg collecting and cleaning equipment with soap and water after use
- disinfect using a solution of 25 millilitres of household bleach (sodium hypochlorite, 5%-6%) and 2 litres of water
- cook eggs to an internal temperature of 74°C (165°F)
- avoid consuming eggs raw or partially cooked (runny yolk)
- avoid using raw eggs in foods that will not be cooked, baked or heat-treated in other ways
- if travelling between separate bird communities during harvest activities (i.e., moving far distances between islands or on land), be sure to
- brush off organic material (i.e., dirt, bird droppings, plant matter) from clothing
- remove organic material (i.e., dirt, bird droppings, plant matter) from rubber boots by stomping feet and/or using a brush to clean the bottom of the boots. After dry cleaning boots using a brush, nearby salt water may be used to rinse them
- change gloves, wash hands or use hand sanitizer in between bird nesting areas.

Information for pet owners
As part of general best practices, it is recommended to keep your cat indoors and your dog on a leash to prevent contact with sick or dead wild birds as well as wild bird feces. Pet owners should not feed pets (e.g., dogs or cats) any raw meat from game birds or poultry. Pet owners can also consult with their veterinarian for more information on avian influenza in dogs and other pets.
