The International Agency for Research on Cancer, a French-based research arm of the World Health Organization, on Thursday reclassified the herbicide glyphosate as a carcinogen that poses a greater potential danger to industrial users than homeowners. The agency cited what it called convincing evidence that the herbicide produces cancer in lab animals and more limited findings that it causes non-Hodgkin's lymphoma in humans. The glyphosate-based herbicide Roundup is a mainstay of industrial agriculture worldwide, and it's a preferred weapon for killing Colombian cocaine harvests. More than 4 million acres of land have been sprayed over the past two decades to kill coca plants, whose leaves produce cocaine. The fumigation program, which is partly carried out by American contractors, long has provoked hostility from Colombia's left, which likens it to the U.S. military's use of the Agent Orange herbicide during the Vietnam War. Leftist rebels, currently in negotiations with the government to end a half-century conflict, are demanding an end to the spraying as part of any deal. Daniel Mejia, a Bogotabased economist who is chairman of an expert panel advising the Colombian government on its drug strategy, said the report is by far the most authoritative and could end up burying the fumigation program. Mr. Mejia's own research published last year found higher rates of skin problems and miscarriages in districts targeted by herbicides. It was based on a study of medical records from 2003-07. Colombia's ombudsman office said it would seek suspension of the spraying program if the WHO results prove convincing. But U.S. and Colombian government officials argue that cocaine does more health damage than aerial spraying. "Without a doubt this reopens the debate on fumigation and causes us to worry," Colombia Health Minister Alejandro Gaviria told the Associated Press on Saturday. - --- MAP posted-by: Jay Bergstrom
