Health Canada have released a health advisory due to mercury levels found in 6 types of ocean fish

Health Canada have imposed a warning pertaining to the mercury levels found in 6 different ocean fish.

The warning applies to fresh and frozen tuna, shark, swordfish, escolar, marlin and orange roughy and is in direct relation to the amount of mercury found in the fish due to their relative size, lifespan and diet.

The legal limit for mercury in these 6 types of fish is 1.0 parts per million (ppm), and according to Canada's food guide, Canadians should limit their intake of seafood to two servings per week.

"It is important to reiterate that fish and seafood can be an important part of a healthy balanced diet and that most Canadians do not need to be concerned about mercury exposure from eating fish," said Samuel Godefroy, Health Canada's director of chemical safety.

"However the types of fish available for sale in Canada has changed over the years and science is regularly updated as new information is discovered," he added.

Recently it was announced that certain types of tuna should be avoided by women who were pregnant due to their dangerously high levels of mercury.

Certain seafood is very nutritious for humans, containing a high amount of Omega-3 fatty acids that are essential for human health.

Canadians are encouraged to consume fish that is considered to be low in mercury but high in Omega-3 fatty acids. Suitable seafood for consumption that meets this criteria would include; salmon, herring, sardines, char, atlantic mackerel, and rainbow trout.
