There are always some dead shells in the seafood market. Some people are collecting them. Can they still be eaten?

    Dead shells are inedible, because the shellfish itself has a high bacterial load, and the protein decomposes quickly. Once it dies, a large number of reproductive pathogens and toxins are produced. At the same time, the unsaturated and fatty acids contained in it are also easily oxidized and rancid. Stale shellfish also produce more amines and their free radicals, which pose a threat to human health.
