The spines can inflict a painful sting if the fish is handled incorrectly. No deaths from its venom have been recorded. Separately, poisoning has been recorded in Israel after people ate its flesh, linked to fish caught in polluted water.1

Hufanya nini akiogopa?

Its spines are barbed and venomous, and they can injure anyone who handles the fish carelessly.1

Miiba yake ikikuchoma

The affected area should be treated with as high a temperature as possible, within 43 to 46 °C, because heat damages the venom. The person should also be checked for possible infection.1
Weka jeraha kwenye maji ya moto, moto kiasi ambacho mtu anaweza kuvumilia bila kuungua (pima kwanza kwa mkono wako), kwa dakika 30 hadi 90. Tafuta msaada wa kitabibu, hasa kwa samaki-jiwe na taa.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Miiba yake ikikuchoma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

Some people have reported hallucinations after eating it.1

Eating its flesh has caused poisoning, and the toxins involved are similar to ciguatoxin.1
