The Avocado is only suited for fresh consumption. It is mainly used for salads and appetizer or as a dip. A hidden occurrence of avocado in food is not to be expected.
Cross reactions: Avocado has common allergenic structures with latex. If one is allergeic or sensitised to latex, a cross reaction with avocado is possible. You can absolutely react to avocado without ever having eaten one. The indoor plant Benjamin’s fig is another possible source for this allergen. If you are sensitised to the plant, you shouldn’t have it in your rooms.
