health - Shanghai warns against eating seafood

Shanghai fishery officials have been issuing warning against eating seafood, writes the Shanghai Daily, as the so-called red ride of plankton expands in the seas bordering neighboring Zhejiang Province.
Especially shellfish and crabs might cause danger in case of human consumption. The rid tide, with the size of 1.3 million soccer fields, is killing life in that area and has stalled fishery. But since the origin of most seafood in Shanghai is unclear, health officials are taking precautionary measures.
