Invasive puffer fish threatens Mediterranean health and ecosystems

Lagocephalus sceleratus Mediterranean invasion bite incidents tetrodotoxin poisoning EODY guidance

The silver‑spotted puffer (Lagocephalus sceleratus) entered the Mediterranean through the Suez Canal and has established dense populations across the Eastern Mediterranean, including Greek waters. Since its first record in Greece in 2005, the species has been identified as a voracious predator of cephalopods, impacting commercial stocks of squid, cuttle‑fish and octopus.

Health authorities report 28 documented bite incidents and at least 170 poisoning cases between 2004 and 2023, of which 27 were fatal. The National Public Health Organization (EODY) advises immediate local antisepsis, haemostasis, sterile wound covering and prompt medical evaluation for bite victims, and warns that tetrodotoxin poisoning from consumption cannot be neutralised by cooking and may require antivenom assessment. The spread of this invasive fish is linked to rising sea temperatures that favour tropical species, a trend noted by marine scientists across the Mediterranean region.
