RESIDENTS wading in the region's waterways should keep watch for the highly-toxic sting of a stonefish after two incidents in Brisbane at the weekend.
Warning signs have been erected at Raby Bay south of Brisbane after two adults were stung by the deadly fish while walking in the water.
Both were taken to hospital for treatment.
Surf Lifesaving Queensland Wide Bay and Capricorn regional manager Craig Holden said there was no increased risk to the public, but swimmers should be vigilant.
"Anytime people go for a swim in the ocean, they need to be aware there are potential hazards," he said.
"I think people need to be aware whilst those hazards exist, it's not common to come across something like that."
Mr Holden said beachgoers could minimise risks by simply swimming between the flags.
"Be cautious, keep an eye out for things that could sting, jab or bite," he said.
"Lifesavers are there to keep an eye out for those things.
"Go to patrolled beaches and you're less likely to have any issues."
Mr Holden said with stonefish usually inhabiting rocky areas, swimmers at Hervey Bay's sandy beaches were less likely to come across one.
People walking through rocky areas are being encouraged to wear thick-soled shoes.
WHAT TO DO
- Ring 000
- Inundate the sting area in water as hot as bearable
- If pain continues after the hot water, use freezing cold water.
- Seek urgent medical attention
