The International Agency for Research on Cancer, a French-based research arm of the World Health Organisation, has reclassified the herbicide glyphosate as a result of what it says is convincing evidence the chemical produces cancer in lab animals and more limited findings that it causes non-Hodgkin's lymphoma in humans. The ruling last week is likely to send shock waves around the globe, where the herbicide Roundup is a mainstay of industrial agriculture. In Colombia, there is an added political dimension stemming from the fierce debate which has raged over a programme that has sprayed more than 4 million acres (1.6 million hectares) of land in the past two decades to kill coca plants, whose leaves are used to produce cocaine. The fumigation programme, which is financed by the US and partly carried out by American contractors, has long been an irritant to Colombia's left, which likens it to the US military's use of the Agent Orange herbicide during the Vietnam War. Daniel Mejia, a Bogota-based economist who is chairman of an expert panel advising the Colombian government on its drug strategy, said the new report was by far the most authoritative and could end up burying the programme. A paper he published last year, based on a study of medical records between 2003 and 2007, found a higher incidence of skin problems and miscarriages in districts targeted by aerial spraying. Colombia has already been scaling back fumigation in favour of manual eradication efforts amid mounting criticism. Sapa-AP - --- MAP posted-by: Jay Bergstrom
