Phuket Issues Urgent Warning Over Venomous Jellyfish Surge

Authorities in Phuket have issued an urgent warning after a surge in venomous jellyfish was recorded near Maiton Island, prompting immediate safety measures.

The Department of Marine and Coastal Resources (DMCR) advised tourists and marine operators to avoid entering the water in the affected area after marine specialists detected a high concentration of dangerous jellyfish. The findings were reported by veterinarians from the Siritharn Rare Marine Animal Rescue Center.

According to officials, the species identified belongs to the Pelagia group, often referred to as “fire jellyfish.” During high tide, their density reached as many as 40 individuals per 100 meters. These jellyfish are relatively small, measuring around 2–3 centimeters in diameter, but are capable of causing painful stings, skin irritation, and itching.

Authorities confirmed that several tourists and boat crew members had already experienced mild symptoms after coming into contact with the jellyfish.

In response, all water activities in the area were temporarily suspended to prevent further incidents. Officials also launched a public awareness campaign, providing safety advice and first-aid instructions through QR codes to help people respond effectively in case of stings.

The DMCR explained that such jellyfish tend to appear in large numbers during specific seasonal conditions, particularly around high tide, making increased caution necessary.

Officials are urging both visitors and local operators to cooperate by avoiding water activities until the situation improves, emphasizing that these precautions are essential to protect public safety and maintain confidence in Phuket’s tourism sector.
