The supermarket giant has restricted the number of cartons sold to each customer after bird flu was detected on another Victorian farm.

Coles has introduced national limits on egg purchases due to a growing bird flu outbreak in Victoria.

The highly pathogenic H7N3 strain of bird flu has been detected on five farms in the state’s southwest, with more than half a million chickens euthanised
in an effort to stop the spread of the disease.

The supermarket giant’s customers in every state and territory can now only buy a maximum of two egg cartons, with the exception of Western Australia.

Coles says the limit is temporary but has not revealed how long it is expected to last.
