Salmonella is a bacteria commonly found in animals, including poultry. It can cause illness to humans such as gastroenteritis (commonly known as ‘gastro’) when contaminated food is consumed.
Until September 2018, Salmonella Enteritidis (SE) had not been detected in NSW poultry. SE is a type of Salmonella that is present in most international egg industries. Salmonellosis is one of the most common and widely distributed foodborne diseases.
SE is high-risk for causing foodborne illness in humans - which can be particularly severe for people who are elderly (over the age of 70), young children, and those with a weakened immune system.
Salmonella Enteritidis (SE) can be spread from property to property through the movement of birds, eggs, manures, produce, equipment, feed, rodents, people and vehicles.
Animal and human health sectors and food authorities have responded to a number of cases of human illness linked to Salmonella Enteritidis (SE) in egg production. Usually human illness linked to SE in NSW is associated with recent overseas travel; people getting infected overseas before returning home. In May 2018, there was an emergence of cases where people became infected from consuming food in NSW.
NSW government agencies worked collaboratively to identify the sources of these cases. In September 2018, Salmonella Enteritidis was first identified in NSW and since then 16 NSW poultry egg facilities and five Victorian poultry egg facilities have had detections of SE. All the properties confirmed to have had SE present are interconnected in that people, eggs or equipment were moving between them.
Every effort is being made by government and industry to limit the spread of SE while assessing management options. Steps taken to minimise consumer exposure to SE include movement restrictions, decontamination and improvements to biosecurity, consumer level and trade level recalls, product withdrawals, consumer advisories, media and surveillance.
NSW DPI is working closely with local and interstate agencies, affected producers and peak industry bodies as part of the ongoing management of SE.
NSW DPI has increased surveillance and monitoring at poultry facilities and we are working with industry to raise biosecurity standards and limit the spread
NSW has strong systems in place at all points along the food supply chain, from paddock to plate, to help reduce the risk of Salmonella Enteritidis (SE).
In the event there is a food safety risk, the recall of affected products is a normal and routine part of a business’ food safety system. During an egg recall, consumers are advised they should not eat the eggs and to dispose of them in the garbage or return them to the place of purchase for a full refund. Proof of purchase is not required for recalled products.
Salmonellosis symptoms in people include fever, headache, diarrhoea, abdominal pain, nausea and vomiting. Symptoms usually start around six to 72 hours after the contaminated food is eaten and usually last for four to seven days but can continue for much longer.
If you have immediate health concerns you should contact your medical professional in the first instance.
To minimise food safety risks, eggs should be cooked thoroughly, this means they are cooked until whites are completely firm and yolk begins to thicken.

NSW DPI has issued a Biosecurity (Salmonella Enteritidis) Control Order to assist in the management of the biosecurity risk posed by the spread of Salmonella Enteritidis (SE).

Salmonella Enteritidis (SE) can be identified in the poultry industry through:
If a poultry farm or facility has confirmed positive tests for Salmonella Enteritidis (SE) it is quarantined under an Individual Biosecurity Direction (IBD) that is issued by NSW DPI. The IBD puts legal restrictions on the farm so that eggs, birds, other livestock, equipment and litter are only able to be removed under a permit to a licenced or approved facility.
Tracing of facilities or other businesses with recent contact with the affected premises will be undertaken and samples from those properties will be collected and investigated.
A DPI liaison officer will be available for the affected premises to provide advice and support.
Eggs on the premises are restricted from movement or sale. DPI may issue a permit for the eggs to go to pulping. Any movement of eggs, birds etc. is only allowed under a permit to an approved facility.
Affected poultry farms or facilities are required to undergo full decontamination and undertake testing for SE before they can start operating again.
You should have a documented biosecurity program to monitor for and prevent the introduction of Salmonella Enteritidis (SE) on your property or the spread of bacteria between poultry sheds. This could include:
Egg Standards of Australia is a voluntary quality assurance program that has been developed to provide a practical mechanism to demonstrate compliance and continuous improvement with egg production standards. Egg Standards of Australia provides a compliance framework for egg farmers in meeting the needs of regulators, retailers, farmers and customers in areas including hen welfare, egg quality, biosecurity, food safety, work health and safety, and environmental management. Further information is available at Egg Standards Australia.
Over the next 12 months, our compliance officers will be visiting every facility in NSW where eggs are produced, graded or packed, or poultry are bred, raised or kept for meat or egg production, on premises required to be licensed under the Food Act 2003 and Food Regulation 2015. This will include pullet rearing facilities.
These officers will provide free biosecurity signage, assist you to meet your property's licensing requirements and help you to implement the new Control Order.
Alternatively you can download the PDF sign template (PDF, 43.2 KB) and ask your local printer to print them for you.
Salmonella Enteritidis is a notifiable disease under NSW legislation. There is a legal obligation to notify authorities if you know or suspect that birds are infected with this disease.
You can notify by phoning:
