Bird flu has been detected at a fourth Victorian poultry farm, agricultural authorities have revealed.
Agriculture Victoria confirmed the high pathogenicity H7N3 strain of avian influenza was detected on Wednesday at a property in the Golden Plains Shire, in the central-western part of the state.
The farm has been placed into quarantine and Agriculture Victoria staff are working to further restrict the spread.
‘All poultry will be safely disposed of under veterinary supervision, consistent with national policies and the sites will be cleaned and cleared of the infection,’ Agriculture Victoria said in a statement.
The four farms hit with the outbreak are in Victoria’s largest egg-producing region.
Victorian Farmers Federation vice-president Danyel Cucinotta said egg availability could vary between retail outlets.
‘We’re anticipating a flow-on impact to egg supplies in the coming week and are working as hard as possible to maintain availability,’ Ms Cucinotta said.
‘My advice is to shop around at your local grocer, market, or small independent store to buy your eggs.’

It follows the highly-contagious flu being detected in three farms near Meredith and one near Terang – all of which have high pathogenicity of two strains of the virus.
A spokesman confirmed the new detection was within the current 5km restricted area.
Victoria’s chief veterinary officer Graeme Cooke said the new detection was not unexpected.
‘Avian influenza is a viral disease of birds found globally, many species of wild birds, including waterfowl and seabirds can carry the virus but usually show no signs of disease,’ Dr Cooke said.
‘We remind bird owners that housing birds, where practical, is an effective method of minimising direct contact with wild birds.’

However, authorities say consumers should not be concerned about eggs or poultry products in supermarkets as they do not pose a risk to human safety and can be safely consumed.
There are mild strains of the flu that result in few or no symptoms and can go undetected, while other mild strains can evolve into severe strains.
The current outbreaks have resulted in the properties where the virus was detected being quarantined, along with a restricted zone being put in place.
Officials have also issued a ‘housing’ requirement for all birds within the areas.
This means that all poultry farmers, backyard flock and bird owners are required to house or keep their birds in enclosed cages or sheds as much as possible.
