Queensland Health probes rat poison contamination in takeaway

While five people were hospitalized due to fears that rat poisoning may have been caused by contaminated fast food, the investigation continues.

Queensland Health launched the investigation after a group of patients presented to hospital with common symptoms.

All five victims went to Logan and Princess Alexandra hospitals.

Chief medical officer Catherine McDougall confirmed a cluster of cases in the metro south health region, with Brodifacoum detected in patients.

A letter obtained by Nine News called for staff to be on high alert for patients showing signs of otherwise unexplained bleeding.

All five patients are suspected of having ingested Brodifacoum, which is commonly found in rodent bait.

Some symptoms include bleeding gums, easy bruising, and blood in the urine or stool. In extreme cases it can be fatal.

Authorities suspect the poison was obtained from contaminated produce at a fast food outlet in Logan.

Dr McDougall said the department was working to identify the source of contamination and all five patients were expected to recover.

Queensland Health is working closely with food safety regulators to monitor contamination and prevent further incidents.

Health officials say the public should not be overly concerned, but anyone who is concerned should contact their healthcare provider.
