title: [Seafood poisoning in Madagascar: current state of knowledge and results of a retrospective study of the inhabitants of coastal villages].
abstract: In 1996 and 1997, a knowledge, attitude and practice survey concerning seafood poisonings was conducted in 560 villages spread along the Madagascar coasts, gathering 585,000 people. 175 serious and 205 mild seafood poisonings after fish, shark and turtle meals occured during the period 1930 to 1996. Squales (mainly Sphyrnidae and Cacharinidae familiesi) are the most often responsible of serious poisoning (48% of episodes), then other fishes (37%), and mainly of the Clupeidae family (herrings, sardinels), then marine turtles (11%), with Eretmochelys imbricata and Chelonia mydas, and finally crabs (4%). Neurological symptoms are predominant in squale poisonings, neurological symptoms associated with gastrointestinal symptoms are present in 50% of all kind of seafood poisoning episods. Most of episods incame on the East Coast (mainly Toamasina and Antisiranana Region) and on the South-West Coast (Toliara Region). Mild seafood poisonings are spread along all the Coasts but central East Coast; fishes are the most often responsible (41% of episodes). Gastro-intestinal symptoms are the most conmon. More than 50% of t interviewed people knows about poisoning risks with some kind of marine animals, but less than 20% practice preventive measures such as giving a piece of fished animal to a domestic animal before eating. These results are used to plan a comprehensive epidemiological surveillance and control programme.
