Agent Orange Residue on Post-Vietnam War Airplanes

Fairchild C-123K Provider, U.S. Air Force

Some Air Force Reservists who were crew members on C-123 Provider aircraft, formerly used to spray Agent Orange during the Vietnam War, have raised health concerns about exposure to residual amounts of herbicides on the plane surfaces.

Responding to these concerns, VA asked the Institute of Medicine (IOM) to study possible exposure and increase in adverse health effects in C-123 crew members.

IOM released its report, Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft, Jan. 9, 2015. VA appreciates IOM's extensive review. We have assembled a group of clinical and other subject matter experts to review and respond to the report.

If you have health concerns, talk to your health care provider or local VA Environmental Health Coordinator.

How Reservists may have been exposed

TCDD, the toxic substance in Agent Orange, may be inhaled as an aerosol or ingested by contaminated food or water or from hand-to-mouth transfer.

During the Vietnam War, the U.S. Air Force used C-123 aircraft to spray Agent Orange to clear jungles that provided enemy cover in Vietnam. At the end of the spraying campaign in 1971, the remaining C-123 planes were reassigned to reserve units in the U.S. for routine cargo and medical evacuation missions spanning the next 10 years.

Research studies on Agent Orange

Research on the health effects of Agent Orange has been extensive and it continues. Diverse populations have been studied, including herbicide sprayers and manufacturers, other Vietnam-era Veterans, and those exposed during industrial accidents. This information helps us to determine what potential health effects may be related to different levels of exposure.
