Medical Sciences Department produces test kit to detect puffer-fish toxin

The symptoms caused by tetrodotoxin, a neurotoxin found in puffer fish, typically develop within 2030 minutes of consumption. The poison's effects start with paraesthesia of the lips and tongue, muscle weakness and respiratory difficulty, Vallop said.

In severe cases that are not treated in time, death can follow within six hours. The highest concentrations of the poison are found in the fish's liver and ovaries, followed by the skin and meat, he said.
