The World Wide Fund for Nature has issued a health warning about eating fish caught in the Baltic Sea

The World Wide Fund for Nature has issued a health warning about eating fish caught in the Baltic Sea. The organisation says the concentrations of toxic chemicals from industrial waste are sometimes so high that they exceed European limits. The levels of some chemicals are between two and five times higher in the Baltic than in the North Sea and the Arctic Ocean. As long ago as 1995, the Swedish authorities issued a warning to women of childbearing age to limit consumption of herring and salmon from the Baltic due to the risk of birth defects.
