The congressionally mandated report, Veterans and Agent Orange: Update 1996, is the second in a series of biennial reassessments of the health effects of Agent Orange and other herbicides.

The report also described "limited or suggestive" evidence, based on studies of occupational exposure to herbicides or dioxin outside of Vietnam, that exposure may be
