Deutsche Welle tells a strange story:

Police in Hamburg have issued a warning to the perpetrators of the hazelnut heist not to consume any of the ill-gained goods, as the sacks containing the nuts were full of poisonous phosphate gas, Reuters news agency has reported.

The deadly gas is used to extend the shelf life of the nuts, which have to first be treated before they’re safe to munch on.

Deadly gas to extend shelf life? Sounds like a great trade-off.
