Louisiana's Department of Health and Hospitals says 334 people have reported illnesses blamed on oil or dispersants from the BP PLC Gulf of Mexico oil spill.

The figures released Monday include 250 people — or about three-quarters of the total — involved in spill cleanup or offshore work, and 84 people in the general public.

DHH says doctors cannot verify reported exposures. Common complaints include headache, dizziness, nausea, weakness or fatigue, and throat irritation.

The department summarizes reports of visits to doctors and emergency rooms, treatment by ambulance crews and calls to hot lines and poison control centers.

Those often come in weeks after a visit, so Monday's figures cannot show whether numbers have dropped since July 15, when a cap blocked the flow of oil.
