THE Sea Fisheries Officials at Gansbaai in the Southern Cape on Monday warned the public not to eat potentially poisonous shell fish which has washed out onto the beaches. SABC radio news reports that Sea Fisheries spokesman Stanley Dramat said it is unclear what caused the washout of shell fish, which included starfish, abalone and mussels. He asked the public to take the shell fish, which may have been infected with toxins from red tide, to a nearby Sea Fisheries office so that it can be examined.
