The following information was issued on behalf of the Canadian Forces Surgeon General. It was intended to assist CF medical staff in placing the health risk in context and to serve as a direct reference for concerned CF members who desire more detailed and specific information than is available from existing herbicide and dioxin information sheets produced by various health authorities.
This document summarizes the findings of scientific studies and reviews specific to Agent Orange or otherwise relevant to recent concerns regarding human exposure and health effects of unregistered herbicides tested at CFB Gagetown June 14-16, 1966, and June 21-24, 1967. This document is organized into four main sections. The first three sections ( "GENERAL INFORMATION" , "HEALTH EFFECTS" , and "FATE IN THE ENVIRONMENT" ) provide background information. Much of this background information is related to the United States use of Agent Orange and other herbicides during the Vietnam War and the scientific study of exposed U.S. Vietnam veterans. This background information is necessary to provide context for the discussion in section four ( "HEALTH EFFECTS FROM SPRAYING IN GAGETOWN" ) of health risks related to the testing of Agent Orange and other unregistered herbicides at CFB Gagetown June 14-16, 1966, and June 21-24, 1967.
DND has also used other (registered) herbicides at CFB Gagetown and across Canada since the 1950s. This broader use of registered herbicides will be reviewed over the next several years and relevant health information will be provided separately in the future. Although this document focuses on the testing of unregistered herbicides at CFB Gagetown June 14-16, 1966, and June 21-24, 1967, parts of this document would also be relevant to the discussion of potential health effects from chemical exposures in general (see especially "Under what circumstances might Agent Orange or its ingredients lead to health effects?" ).
