One of the major industries in the small seaacost town where I live is clam purification. Clams are filter feeders, and they accumulate whatever passes through them. This can include disease bacteria and chemical pollutants. Someonone who'd been to the West Coast knew about the native "clam farms", and brought the technique here. THey get some fresh sand and clean it as clean as they can, then bed the clams on it until they have expelled anything we don't want them to carry. Then they sell these cleaned clams in local supermarkets and restaurants all up and down the East Coast.
