We evaluated 13 workers with respiratory symptoms apparently related to occupational exposure to powdered rose hips. Nine workers had asthma, five had rhinitis, and one worker had urticaria. Seven workers had evidence of IgE specific for rose hips based on positive skin prick tests and positive in vitro tests. Four workers with histories suggestive of asthma related to work exposure underwent bronchopulmonary challenges with rose hips, and two workers had positive challenges with >20% declines in FEV1 measurements. We conclude that rose hips are occupational allergens capable of producing asthma.
