Firms in Sweden have sold about 200 tonnes of Baltic salmon in Europe despite an EU ban targeting toxic chemicals in fish, officials say.
The ban does not apply to Baltic salmon sold to domestic consumers in Sweden, Finland and Latvia. But the sellers are required to give advice about safe limits for consumption, set by the EU.
Dioxins found in Baltic herring and salmon prompted the EU ban in 2002.
A French firm imported 103 tonnes of Swedish salmon, but no longer does so.
