Authorities said the H7N8 strain had been detected at the farm in Euroa, which was located near two other infected properties.
Australians are struggling to find eggs stocked on shelves across the country, which has prompted supermarkets to keep limits in place.
Coles told 9news.com.au that it will keep egg purchase limits in place for the foreseeable future.
“Coles is closely monitoring the confirmed outbreak of avian influenza in Victoria. We will continue to work closely with all our suppliers to ensure eggs remain available for our customers,” a spokesperson said.
“To manage availability, we will continue to maintain the purchase limits that have been in place since the first outbreak in Victoria in 2024.
“We kindly ask our customers to consider others in their community and purchase only what they need.”
Costco was contacted for comment, but declined to provide a statement.
9news.com.au understands current limits on eggs apply.
Woolworths confirmed the two-pack purchase limit on eggs remains in place, in all states except for Western Australia.
“In June last year, Australia’s egg industry was affected by a bird flu outbreak, which has since been contained. The outbreak reduced the number of laying hens in Australia, which unfortunately will take a while longer to rebuild,” the spokesperson said.
“In the meantime, the egg industry is working to boost supply marketwide.
“The usual higher demand for eggs over Christmas and the New Year’s period put an additional short-term strain on the availability of eggs across all retailers, however our supply remains stable.
“Our egg supply has continued to improve and we are working closely with our suppliers to source as many eggs as possible.”
Egg Farmers of Australia chief executive Melinda Hashimoto told 9news.com.au last month, that there is a national shortage.
Agriculture Victoria said the farm’s positive result was not unexpected, and urgent testing would continue to determine where else the disease may be present.
Victoria’s Acting Chief Veterinary Officer Dr Cameron Bell said staff were on the ground “working closely with industry to contain and eradicate the virus”.
Control orders remain in place restricting the movement of poultry, poultry products, equipment, and vehicles on or off properties in designated zones.
The zones include a restricted area covering a 5km radius around the farms, with a broader control area spanning east of the Goulburn Valley Freeway and including the townships of Euroa, Violet Town, Longwood, Ruffy, Avenel and Strathbogie.
“If you are in the control or restricted areas, you cannot move birds, products (including eggs and manure) or equipment into, out of, or within the area without permit,” Bell said.
“This includes selling or giving away eggs from your poultry – these must not leave your property.”
