In many African and Asian countries, brood combs are considered a delicacy and consumed immediately when available. They are also particularly rich in protein since they usually contain quantities of beebread, i.e. the slightly fermented pollen stores of the hive. In some Asian countries, worker or drone pupae (in their white stage) are also prepared for human consumption by pickling or boiling. In canned form, they are found in some European or American specialty stores and can be considered a value added product, even if there is not much demand or a broad market perspective in the West.
