Adding an allergen in quantities where it has no meaningful effect is attempting to flout a regulation. It's like bringing money into the country by spitting it among fellow travellers. In a functioning system the authorities would have the power to investigate and use discovery to identify cases where allergens are being added deliberately for no other reason than flouting rules. They should then be able to issue substantive fines to encourage actual compliance. Its not like adding small amounts of an allergen is a victimless. Lots of people with moderate to serious allergies eat things every day which "may contain" their allergen.
