A Canadian Treat Deemed a Threat?

Every spring, young ferns start to spout in form of fiddle-heads.

Here in Canada, we consider these sprouts as a delicacy, preferrably steamed and served with salted butter on top.

But, as the good people at the Canadian Food Inspection Agency noted, there's a toxin that, if not properly washed and boiled out, may cause symptoms such as diarrhea, dizziness and nausea.

But if you decide to come up for a visit, don't deny yourself this otherwise tasty and nutritious treat.

Mmmmm... fiddleheads!
