Two men have suffered terrifying visual and auditory hallucinations after eating a popular local seafish in Mediterranean restaurants

According to a clinical study on the patients, which is due to be published in the journal Clinical Toxicology, the men started seeing and hearing things after contracting a rare form of hallucinogenic poisoning from the Salema fish they were dining on.

Ichthyoallyeinotoxism, or hallucinogenic fish poisoning, is caused by eating the heads or body parts of certain species of herbivorous fish and has previously only been recorded from the Indo Pacific.
