All about shellfish
What are the nutritional benefits of eating shellfish? Is it risky to eat shellfish in periods of high green algae proliferation? What are ANSES's activities regarding shellfish health? See our articles on this topic.
Shellfish live in seawater and are in contact with the seabed where they find food including plankton and suspended substances. The quality of shellfish is therefore dependent on water and sediment quality. To ensure the safety of shellfish for the consumer, and to protect shellfish health, the Agency is involved in three main areas.
Every summer for more than 30 years, massive quantities of green algae have been washing up on parts of the French coastline. Once washed up on beaches, these algae deposits decompose and produce large quantities of gases, especially hydrogen sulfide (H2S), potentially exposing walkers, local residents and workers required to collect these algae, to risks. The issue of the risks associated with these algae when bathing or consuming shellfish, is also raised. Below are details of the Agency’s work on this topic.
