Canadian NGO Vigilance OGM said Thursday that it believes the first-ever genetically modified (GM) salmon sold unlabeled into the Canadian market likely ended up on the plates of consumers in Quebec.

In August, it was discovered through a company financial filing that AquaBounty, the world's only producer of GM salmon, sold roughly 5 metric tons into Canada. The company refused to give any details about the wholesale buyer or buyers of the fish and where those fish were eventually sold to consumers in Canada.
