Wild birds have also tested positive for H5 strains of bird flu in or near 100 Mile House, Bowen Island, Chilliwack, Kelowna, Metro Vancouver, Vanderhoof and Williams Lake, according to the British Columbia government.

How severe is this outbreak and can we expect to see it appear in more flocks?

Experts say the H5N1 strain is highly contagious and spread across North America most likely by migratory wild birds. Outbreaks of the same strain have also been detected in Newfoundland and Labrador, Nova Scotia, Ontario, Saskatchewan and Alberta.

BC has extended its order for all commercial poultry operators with more than 100 birds to move their flocks indoors through June 13.

The Canadian Food Inspection Agency is expecting more cases, and so far says an estimated 1.7 million birds have been killed or killed by the virus in Canada, mainly in Alberta and Ontario.

No infections have been detected in humans, and the Canadian Food Inspection Agency says there is no evidence to suggest that eating poultry or cooked eggs can transmit the virus to humans.

Should people feed wild birds?

not now.

The BC SPCA urges people with backyard bird feeders to take them down temporarily to reduce the risk of transmission of the highly contagious virus.

The virus is believed to be spread by infected wild birds that migrate north for the summer and are shed through faeces and respiratory secretions that may remain in the environment for several months.

Bird feeders and bird baths can increase the risk of bird flu spreading to backyard poultry, said Dr. Andrea Wallace, director of wildlife care at the SPCA.

The organization is asking people to temporarily remove their feeders, empty water baths and monitor their surroundings for signs of sick birds. Symptoms can include lethargy, nasal discharge, excessive tearing, swelling of the head and eyelids, and an unusually “puffy” appearance.

Can my other pets catch the virus?

This strain of bird flu is found in chicken, turkey, quail, guinea fowl, wild birds, and domestic animals, according to the CFIA. It has been detected in mammalian species including humans, rats, mice, weasels, ferrets, pigs, cats and dogs.

However, the number of documented cases of AI H5N1 in non-avian species is very low despite the fact that this virus has caused worldwide outbreaks of birds, over the past few years, according to CFIA.

The agency stresses that the chance of someone contracting bird flu from a pet is extremely low.
