I have four children and so far there's no evidence any of them have a tree nut allergy. Two are quite young, so there's still time for such an allergy to manifest itself, but I'm hopeful we've avoided it.
I do have a nephew, however, who is allergic to peanuts. It means when we host a party we have to buy the ice cream that is completely nut free, and when we bake cookies or a cake, all labels must be read! A McDonald's Happy Meal, you'd figure, would be a safe choice.
McDonald's Canada has added a Skor McFlurry to its menu, and that means they can no longer be sure their other products have not "come in contact with peanuts, tree nuts or other allergens".
In my mind, this is a poor trade. McDonald's adds one more flavour of McFlurry to its menu and the cost is telling every family with a child with a nut allergy that their restaurant is no longer safe. Based strictly on my unscientific sniff test, it hardly seems worth it.
In fact, I think it's nuts.
