ISSC committees and task forces generate revisions and resolutions that are forwarded to FDA for approval. Once the revisions and resolutions are approved, FDA adds them to the NSSP Manual of Operations. To sell oysters in interstate commerce, states must have industry and health agency practices that are consistent with the NSSP Manual of Operations. State health agencies comply by routinely monitoring, classifying, and opening and closing shellfish growing and harvesting waters in the interest of consumer protection. Like most seafood, oysters provide sound nutrition.
Oysters are moderately low in sodium.
Oysters are frequently marketed live in the shell. They are also sold fresh or frozen, as canned meats, or frozen and breaded. Live oysters are sold by the dozen, by the bushel bag, or in bushel-fraction boxes. Six live oysters per person is a normal portion, although many people will eat more. If you purchase oysters in the shell, make sure that they are alive.
