AquAdvantage salmon

The Canadian Food Inspection Agency says genetically modified salmon produced in Prince Edward Island is "available for sale" in Canada, but when and where consumers can purchase the food remains unclear.

Environmental groups say the first shipment of genetically modified salmon in the world arrived in Canada earlier this year and likely ended up on the plates of Quebec consumers.

The federal government says a proposal to produce the world's first genetically modified salmon for human consumption in P.E.I. will face environmental assessment.

A controversial genetically-modified salmon designed to grow faster received FDA approval Thursday, becoming the first approved GM food animal.
