Spinach is predominantly processed as frozen good. On the market, it is also contained in fillings (ravioli, tortellini, cappeletti, strudels, etc.) or as a soup ingredient. Fresh spinach is used for salads and dips. Products containing spinach are correspondingly labelled; therefore, a hidden occurrence in the food is not to be expected.
Cross reaction: Spinach has common allergenic strucures with latex. If one is allergic or sensitised to latex, a cross reaction with spinach is possible. You can absolutely react to spinach without ever having eaten it. 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.
