In early 1993, the Engineering Control Technology Branch of the Division of Physical Sciences and Engineering was asked to assist in a Occupational Asthma Identification project being carried out by the Clinical Investigations Branch of the Division of Respiratory Disease Studies (DRDS) by evaluating engineering controls used in insect rearing facilities. This was to be done while assisting Patrick Hintz, Environmental Investigations Branch, DRDS with an industrial hygiene evaluation of three insect rearing facilities operated by the Animal and Plant Inspection Service, Plant Protection and Quarantine Programs, U.S. Department of Agriculture. Observations were made at the Pink Boll Worm Rearing Facility in Phoenix, Arizona, August 22-26, 1993; the Mexican Fruit Fly Rearing Facility in Edinburg, Texas, August 28-30, 1993; and the Gypsy Moth Rearing Group at Otis Air National Guard Base, Massachusetts, November 1-4, 1993. At the time of these surveys, suspected asthma was found in some workers, but the cause of the disease was unknown. It was assumed that insect parts might be a major factor, however, the specific antigens and dose were not established. Thus, there was no guidance as to the sources of hazardous emissions or to what chemicals or substances needed control. Limited resources precluded a comprehensive study of the ventilation and other control systems. Therefore, the controls evaluated in this study were limited to those operations incidental to the industrial hygiene study which was carried out at each facility.
