A new health warning has been issued by the French health authority Anses (Agence nationale de sécurité sanitaire), which reports several cases of poisoning following the consumption of what is commonly known as “wild asparagus” — in fact, a different plant altogether. Over the last 10 years, poison control centers have recorded 48 such cases. Lab analysis of wild asparagus samples revealed “numerous calcium oxalate raphides, microscopic crystals known for their irritating effect,” explains Anses, adding that “during the same meal, some consumers were affected while others were not, suggesting individual sensitivity.”

This perennial plant, known as Ornithogalum pyrenaicum (Pyrenean Star of Bethlehem), actually has very little to do with cultivated asparagus, apart from its light green, spear-like flower stem — a slight resemblance that unfortunately leads to frequent confusion.

“Since the news articles began mentioning these poisoning cases, some growers have expressed concerns about confusion between the two species. I’ve even witnessed it myself — acquaintances told me they’ve stopped buying asparagus out of caution. But these two plants are completely unrelated. It’s crucial to communicate on this subject to prevent the industry from suffering because of this serious misunderstanding. Unfortunately, even the media is contributing to the confusion, with some outlets illustrating their articles using photos of cooked green asparagus,” explains a sector professional.
