WHO Report Links Weed Killer Ingredient To Cancer Risk

An anonymous reader sends word that a common weed killer may cause cancer according to the World Health Organization. "The world's most widely used weed killer can 'probably' cause cancer, the World Health Organization said on Friday. The WHO's cancer arm, the International Agency for Research on Cancer, said glyphosate, the active ingredient in Roundup and other herbicides, was 'classified as probably carcinogenic to humans.' It also said there was 'limited evidence' that glyphosate was carcinogenic in humans for non-Hodgkin lymphoma." Unsurprisingly, Monsanto, Roundup's manufacturer disagrees saying there is no evidence to support the findings and calls on WHO to hold a meeting to explain their conclusions.

    The chances are very good that the last piece of bread, pastry, gravy or soup thickened with flour you have had, would have roundup on it. Thanks to the crops being treated right before harvest.

    Many farmers will use roundup a few days before harvest because it dries the wheat out. http://www.washingtonsblog.com...

    glyphosate breaks down into what ?

    It is basically an amino acid (glycine) with a phosphate group attached. It can be fully metabolized by soil bacteria into phosphorus, nitrogen, CO2 and water. It has a half-life in soil of about 50 days. It has a half-life in surface water of about 90 days. It can be toxic to fish, and runoff is a problem. It should not be applied if rain is expected.
