And peanuts in something that isn't obviously made of peanuts, of course. That's what allergen labels are for, nobody's arguing against that.
But you can't really mistake a bar of butter for anything else except margarine. And it you have a milk allergy, you're gonna make sure you know what the words are for butter vs. margarine, I should think?
Regulations that require the allergen labeling and don't make exceptions will obviously be shorter than regulations that make exceptions.
If the outcome were worse for consumers, I can see arguing for the more complicated regulation, but having a clear statement of the allergens regardless of the product doesn't hurt consumers any (If you disregard the bother from the redundancy anyway).
No, I'm just saying that in this particular instance literally nobody should have suffered any harm.
Not everyone speaks perfect english. One of the times I had an allergic reaction, it's because I didn't know all the Spanish word for peanuts... and the english translation right below it skipped that word.
