This Chinese Field Epidemiology Training Program (FETP) resident, was photographing 43 types of puffer fish, while investigating an outbreak of tetrodotoxin poisoning in August 2012, in Guangdong, a coastal province of southeast China. The photographs were created in order to help consumers identify the contaminated puffer fish.
Additional Information:
”Tetrodotoxin is an extremely potent poison (toxin) found mainly in the liver and sex organs (gonads) of some fish, such as puffer fish, globefish, and toadfish (order Tetraodontiformes), and in some amphibian, octopus, and shellfish species. Human poisonings occur when the flesh and/or organs of the fish are improperly prepared and eaten. Tetrodotoxin interferes with the transmission of signals from nerves to muscles and causes an increasing paralysis of the muscles of the body. Tetrodotoxin poisoning can be fatal.”
