Lambton Public Health (LPH) has confirmed a report of H5N1 avian influenza in birds within the county.
No human cases have been reported at this time.
The health unit said only those who work with the affected birds are considered to be at risk and LPH has followed up with those individuals.
Avian influenza is a viral disease that mostly affects domestic poultry and wildlife.
“Although it can be easily spread amongst birds, avian influenza does not easily cross from birds to humans, and the risk of human-to-human transmission is even lower,” said Acting Medical Officer of Health Dr. Karalyn Dueck.
Although the risk of human infection is low, residents are encouraged to avoid handling wild birds. If handling birds, protective measures include hand washing and wearing personal protective equipment when appropriate.
"Transmission of the virus from eating eggs or poultry is unlikely, however proper safe food handling practices should be followed, including keeping poultry and egg products separate from other food products as a general practice," read an LPH media release.
The H5N1 virus was first detected in Ontario in March and has been primarily attributed to the migration of infected waterfowl.
The LPH investigation involves a collaboration with the Ontario Ministry of Health, the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), and the Canadian Food Inspection Agency.
Reports of sick or dead birds can be made to the Canadian Cooperative Wildlife Centre by calling 1-800-673-4781.
