The U.S. Food and Drug Administration (FDA) recently released a factsheet on the 2022 Food Code definition and requirements for “in-shell product,” which is a sub-category of molluscan shellfish that requires special parameters for safe handling.

Shellfish are filter feeders, and may concentrate microorganisms (bacteria and viruses), as well as natural toxins and chemicals if they are present in the growing waters. The current National Shellfish Sanitation Program (NSSP) dictates uniform requirements that every state must meet, with federal oversight provided by the U.S. Food and Drug Administration (FDA). States are required by the NSSP to maintain minimum sanitation standards addressing issues such as water quality monitoring, harvest area enforcement, training of harvesters and dealers, processing, shipping, and handling.

A research team from the University of New England is addressing the lack of regulatory oversight of edible seaweed by studying the effect that various food safety control measures have on the presence of pathogens on the crop. The researchers also explain why seaweed should not be regulated as shellfish.

This article addresses the sources, risk, and management of marine biotoxins found in molluscan shellfish and methods to identify contaminated shellfish meat before marketing. The authors also present an update to the online learning module developed to provide current National Shellfish Sanitation Program marine biotoxin management requirements for molluscan shellfish intended for interstate commerce.

Research scientists in England have discovered that a certain type of Vibrio bacteria can go dormant and later "wake up."

Today, the U.S. Food and Drug Administration (FDA) and the European Commission (EC), have taken important steps to open the market for the sale of molluscan shellfish, including oysters, clams, mussels and scallops, from both the United States and the European Union to their consumers.
