Quebec has had two commercial poultry flocks affected by highly pathogenic avian influenza (HPAI), reported the Canadian Food Inspection Agency.
The presence of the virus was confirmed in a flock in Les Maskoutains on November 17, and another in La Vallée-du-Richelieu on the following day. Information concerning flock sizes or the type of birds involved was not made available.
With these two new instances, Quebec has now had four commercial poultry flocks struck by HPAI during 2024. However, these are the first cases of avian influenza in commercial poultry in the province since February.
So far in 2024, the following provinces have had confirmed cases of HPAI in commercial poultry: Quebec, British Columbia, Alberta, Saskatchewan and Ontario.
Costa Rica declared free of HPAI
The HPAI situation in Costa Rica has been resolved, the World Organisation for Animal Health (WOAH) reported.
While no commercial flocks were ever affected there, the virus did strike 130 domestic birds and 12 wild birds, including a peregrine falcon, nine brown pelicans a red-footed booby and a great frigatebird.
The presence of HPAI was first confirmed in Costa Rica in January 2023, but all control measures there have been successfully carried out and since then, a month has transpired with no new instances of HPAI.
