Rapeseed pollen contains known allergens. Whether rape pollen causes hay fever has not been well established, because rape is an insect-pollinated (entomophilous) crop, whereas hay fever is usually caused by wind-pollinated plants. The inhalation of oilseed rape dust may cause asthma in agricultural workers.
