The Norwegian medias suspect cassava, a very common vegetable in the Asian kitchen, to be the killer of the two tourists on Phi Phi. The plant has previously caused the deathe of Philippine children. Cassava can produce the poisonous Prussic acid when not cooked properly – which could have caused the decease of the twenty-two-year-old Norwegian girl Julie Michelle Bergheim and the twenty-six-year-old Jill st. Onge from USA, who recently died after massive pains in their stomachs on the same hotel on the Phi Phi Island in Thailand.
The Thai police have now confirmed that there has been found cyanide – a biproduct of Prussic acid in the stomachs of both women. That has led to the theory of the Cassava-poisoning. Due to the investigations, bars and restaurants on the island have been examined, and the hotel where the women stayed is temporary closed.
Cassava is infamous for its deadly acid. In 2006 25 Philippine children died after eating snacks made of the plant.
