A 36-year-old man with adult-onset nonallergic triad asthma developed acute bronchospasm and copious sputum production during an offshore sailing excursion on the Gulf Coast of Florida. Symptoms were linked to proximity to blooms of the marine dinoflagellate Karenla brevis (‘red tide’) and heavy aerosollzed brevetoxin exposure, and symptoms recurred during rechallenge. Patients with respiratory disease who are planning a visit to red tide-prone seaside areas should be cautioned to bring their pulmonary medications, and clinicians should be aware that reactive airway symptoms may be triggered by exposure to red tide.
