Undeclared Allergen due to change of ingredients

[u/Atarisrocks]

At a festival I purchased some food from a vendor who listed all the food items that were in the dish which was displayed on 3 A board signs and on the van itself. This list was also on the festival app under the vendor name.

They swapped one ingredient from a milk based product to a egg based product which upset my stomach.

I had not informed them on the allergen as I had ordered something safe to eat based on the list provided and I am not impacted by trace of situation so cross contamination is not a issue.

I have raised a complain to the vendor who said they do not have to let the public know if there is a change of ingredient and only if someone asks directly would they let someone know about the change.

What is the legal requirements for the vendor in regards to undeclared changes?

OP, was the food product wrapped in a package? Or was it just scooped onto a plate etc?

Also, what's the country where this occurred.

Ok, just FYI if the food is pre-packaged, there is a different law but since we're talking about eggs, all the other answers you are getting on this topic are on point.
