The aim of the paper was the examination of allergic organisms presence, particularly of arthropods in dry food in rooms of their storage, as a factor of the environment sanitary and hygienic state. We examined 258 samples of swipes and alimentary products (i.e., eggs, flour, cereals, pea, bean, sugar, macaroni, and other) to identify arthropods within. Randomly taken samples were investigated for the presence of pathogenic bacteria and toxic moulds. "Arthropod's stroke" in 33% of 258 samples was found with significant differences connected with year of investigation. We found positive correlation between arthropod's stroke and bacteria presence.
