Tests find levels of Listeria detected at Queensland Children’s Hospital unlikely to impact human health

30 May 2019 

There have been no cases of Listeriosis-related sickness reported in or to the Queensland Children’s Hospital since routine food testing detected a trace of the bacteria in ham served to patients and families at the Queensland Children’s Hospital.

Forensic testing of the sample has found that the level of Listeria monocytogenes detected was very low at less than 10cfu/g. This constitutes a ‘not detected’ level in accordance with the Australia and New Zealand Food Standards (less than 10 cfu/g) and does not meet the threshold for product recall.

This trace level is considered unlikely to have an impact on human health.

Further testing of multiple samples from the batch of ham in question has not detected any trace of the bacteria.  Independent environmental testing has also found no trace of the bacteria in the hospital kitchen.

In consultation with the Chief Health Officer and Metro South Public Health Unit, Children’s Health Queensland has reviewed its established food and environmental testing processes and is confident there is no listeria-related risk to patients and families at the Queensland Children’s Hospital.

Patients and families who were in the potentially affected wards and departments during 10 and 20 May were notified of the detection via direct correspondence and made aware of the signs and symptoms of Listeriosis.
