Listeria Outbreak Update

Information for clinicians

1. A national outbreak of listeriosis has been reported related to rockmelon
2. Advise patients at increased risk of listeriosis to avoid consuming high risk foods
3. ONLY test if the patient has symptoms consistent with listeriosis and is at higher risk of developing listeriosis. There is no value in testing asymptomatic patients.


Fifteen cases of listeriosis have been reported in elderly and immunocompromised people across New South Wales (NSW) so far this year, including three deaths.

A national outbreak of ten cases affecting three states and territories (including six cases from NSW) has recently been linked to a rockmelon grower in Nericon NSW. Consumers are advised to discard any rockmelon currently in refrigerators if they are unsure of the producer.
