Fish and Health: Contaminants
Saltwater fish rich in fats are a good source of long-chain omega-3 fatty acids. Even if the health benefits of a diet rich in fish are not disputed, the level of contamination of a few types of fish can still be a problem above all for children, pregnant women and people who eat a good deal of fish.
Predatory fish such as tuna can show high levels of mercury and various water species such as herring or salmon may have serious problems with dioxin/PCB contaminations.1
For this reason some years ago the recommended intake levels for fish were partially reduced in some countries.
Maris Omega-3 ingredients are free from contaminants and offer a healthy and safe way to consume EPA and DHA in sufficient quantities.
