Bridgewater Poultry Farm has started culling birds as part of a decontamination effort following a break out of Salmonella Enteriditis.
A spokesperson from Loddon Valley Eggs said the farm continues to work with the relevant government bodies.
The outbreak forced Loddon Valley Eggs to recall stock from from Woolworths and independent stores in Victoria, ACT, NSW and Tasmania, and Coles in Victoria and South Australia.
"Bridgewater Poultry Farm is proactively executing the appropriate processes and working with the Victorian government health and agricultural departments to investigate," the Loddon Valley Eggs spokesperson said.
"Farm and all birds have been quarantined and under instruction from Department of Environment and Primary Industries the standard processes are underway to ensure no further spread of the SE Salmonella strain.
"The health and safety of consumers is something that Bridgewater Poultry Farm takes seriously."
Agriculture Victoria confirmed the farm was still under quarantine.
"The farm in question has commenced culling affected birds and decontaminating affected infrastructure on the farm," an Agriculture Victoria spokesperson said.
"The quarantine order on the farm remains in place to prevent the movement of livestock, equipment and eggs off this farm unless under permit.
"Eggs are only permitted to move for processing by pulping and pasteurisation at an approved facility.
"Agriculture Victoria will ensure that appropriate biosecurity and animal welfare measures are undertaken."
An investigation into the salmonella outbreak is continuing with Loddon Valley Eggs believing it was introduced through the purchase of interstate eggs.
"As is common practice in the egg industry, eggs can be sourced from third-party suppliers to assist with temporary spikes in product demand," the Loddon Valley Eggs spokesperson said.
"Salmonella Enteritidis is not endemic in Australia so it is important to work through how this incident has arisen.
"Regular Salmonella Enteritidis surveillance is conducted in Australia to ensure early detection, containment and eradication of any contamination."
A DHHS spokesman said the five cases of illness related to the contamination affected people aged from 20s to 80s. Two people were hospitalised as a result but have since been released.
Symptoms include fever, headache, diarrhoea, abdominal pain, nausea and vomiting.
The Loddon Valley Eggs spokesperson said consumers concerned about their health should seek medical advice.
Customers who have purchased the eggs should not consume them and return them to the place of purchase for a refund.
