Officials impose restrictions as cases have been confirmed
A case of avian influenza has been confirmed in Nova Scotia, prompting officials to impose restrictions aimed at containing the virus.
According to CTV News, the Canadian Food Inspection Agency (CFIA) identified cases of bird flu among poultry in Shelburne County, N.S., on March 4. The infected birds were located on a non-commercial property, which, according to the agency, refers to flocks with fewer than 1,000 birds and fewer than 300 waterfowl.
In response, CFIA inspector Mike DiMambro declared a primary control zone in the affected area on March 7. This measure restricts the movement of commercial and non-commercial poultry, eggs, and related products to prevent the disease’s spread. The control zone encompasses Shelburne, Carleton Village, Birchtown, and McNutts Island.
Avian influenza is highly contagious among birds and can lead to severe illness and death. While human cases are rare, the Nova Scotia government warns that symptoms can include fever, cough, sore throat, muscle aches, diarrhea, and difficulty breathing.
Amy Vanderheide, chair of Chicken Farmers of Nova Scotia and leader of the Poultry Emergency Response Preparedness Committee, emphasized the severity of the virus and the necessary steps to contain it.
“Avian influenza is extremely contagious. There is no treatment. There’s no cure. The only option, unfortunately, is depopulation,” said Vanderheide. “We know that’s been done on that site and they are working with the Canadian Food Inspection Agency to complete disinfection. It’s unfortunate, but they are doing the right thing.”
Although the exact number of infected birds remains unclear, Vanderheide noted it was fortunate the outbreak occurred in a backyard flock rather than a commercial operation. A case in a commercial barn would necessitate the euthanization of all birds, impacting the food supply.
The detection of bird flu in Nova Scotia comes as the United States struggles with a significant outbreak, leading to widespread culling of poultry, particularly egg-laying hens, and rising egg prices. However, officials do not expect the current case in Shelburne County to impact food supply or prices. Strict biosecurity measures, including third-party audits, help mitigate risks to commercial poultry farms.
“We monitor avian influenza daily. If there are wild bird deaths, we receive reports and follow strict biosecurity guidelines,” Vanderheide said. “But it’s a tiny virus that can get in through the air or on someone’s shoes, so it remains a real possibility.”
She urged backyard flock owners to take precautions, including minimizing contact between their birds and wild birds. Officials also recommend removing bird feeders to limit potential transmission.
Residents who encounter injured, sick, or dead birds are encouraged to report them to the Department of Natural Resources and Renewables.
