Chocolate lovers in Germany have been warned to watch what they eat this Christmas as it could have deadly consequences.
The consumer group “Stiftung Warentest” says traces of mineral oil have been found in advent calendars which may cause cancer.
But some shoppers in one Berlin superstore appeared to take the advice in their stride.
“For chocolate, normally I don’t check what is inside, I thought it was butter and cocoa,” said one woman.
The consumer group says children in particular should not eat the whole month of chocolates and they claim the longer you wait to eat them the bigger the risk.
Some retail associations say they do not think people will be put off by the advice. The German Confectionery Association says there is no health concern because the mineral oil residues are so low. But several supermarket chains have issued a recall of the affected products and reassured worried customers that they can receive their money back.
