There are some cases of that absurdity within EU:

- snails are considered "landborne fish", so that French farmers can receive EU grants for breeding them, from the money pool set aside for fishermen.

- there's a maximum allowed curvative of a banana, so that only bananas coming from former French colonies in Africa are allowed to be sold in the EU (South American banana species are more curved)

- carrot is considered a fruit, so that Portugese producers of carrot jam can sell it outside the Portugal (EU requries that jam must be made of fruit).

- According to EU officials, there's no proof that drinking water helps you hydrate, so producers of bottled water are not allowed to claim that in the advertisement, or on the labels.
