Seafood health alerts

How much is safe to eat?

Fish is generally healthy to eat, but some types should be eaten in moderation (or in some cases, even avoided). This chart lists fish according to their average mercury concentration, including how much can safely be eaten each month (assuming no other contaminated fish is consumed). The advice is based on EPA guidance and the latest mercury data. See the green sections below – or re-sort the list - for safer seafood options
