It's all well and good that Migros labels products with the Aha! seal of approval for allergy sufferers on the shelf.
But as soon as a product is not a Migros own product and therefore does not carry an actual Aha! label, it is not marked on the shelf. This is a great pity and makes life more difficult for us allergy sufferers. The gluten- and lactose-free crispbread from Wasa serves as an example here. It costs four(!) times more than the regular crispbread, but is not specially labeled on the shelf. But it would be so simple: if Migros does not want to or is not allowed to use the "Aha!" label, then a blue (or red or orange) "gluten and lactose-free" label would be added. Or a symbol with an ear of corn crossed out. That way, you can see the product immediately when your eyes wander over the labeling on the shelf, which also works with "Bio" and "Aha!".
That would be helpful and also applies to other products that don't have the "Aha!" label but have been produced and purchased for us allergy sufferers. Coop solves this with the "Free From" label, they often also stick a "Free From" sticker on the product itself.
