The Department of Maritime Fisheries in Morocco has imposed a ban on the harvesting and marketing of small clams from the Ras Kebdana-Saïdia shellfish farming area in Nador, pending the completion of environmental purification following the discovery of abnormally high levels of marine biotoxins in these clams by the National Institute of Fisheries Research. The Department has urged consumers to only purchase packaged products with health identification labels from authorized points of sale to ensure safety, and has warned against the consumption of shellfish sold in bulk, which may pose a public health risk.
