Portuguese man-of-war warning issued for Phuket beaches

Phuket lifeguards have issued a warning after Portuguese man-of-war were found at three beaches on the island.

The alert was posted on the Phuket Lifeguard Service Facebook page on June 14, with photographs showing two specimens collected in a glass container.

According to the warning, the creatures were found at Nai Harn Beach, Kata Noi Beach and Kata Beach. Lifeguards said they have increased monitoring and surveillance to protect beachgoers and tourists.

Officials said Portuguese man-of-war are highly venomous marine animals and can remain dangerous even after washing ashore. Contact can cause severe burning pain, swelling, redness and skin rashes. In some cases, people may suffer serious allergic reactions requiring immediate medical treatment.

Lifeguards urged tourists, swimmers and beach operators to use caution and check their surroundings before entering the water. Beachgoers were also advised not to touch any jellyfish or unidentified marine creatures found in the sea or on the beach.

Anyone who spots a jellyfish resembling a Portuguese man-of-war has been asked to notify the lifeguard on duty immediately. People who are stung should leave the water at once, alert lifeguards or other staff for first aid, and seek medical attention as soon as possible.

The Phuket Lifeguard Service said it will continue monitoring the situation and provide updates during the current period to help prevent injuries from venomous jellyfish.
