Don't drink Roundup [or equivalents]. 5 grams makes most rats sick or dead: <Acute Toxicity Glyphosate is a moderately toxic herbicide and carries the signal word WARNING on the label. Even though the LD50 values show the compound to be relatively non-toxic it can cause significant eye irritation. The toxicity of the technical product (glyphosate) and the formulated product (Roundup) is nearly the same. The acute oral LD50 in the rat is 5,600 mg/kg. Other oral LD50 values for glyphosate are 1,538 to greater than 10,000 mg/kg for mice, rabbits mg/kg, and goats (1, 5). In a number of human volunteers, patch tests produced no visible skin changes or sensitization. Chronic Toxicity Subchronic and chronic tests with glyphosate have been conducted with rats, dogs, mice, and rabbits in studies lasting from 21 days to two years. With few exceptions there were no treatment-related gross (easily observable) or cellular changes (5). In a chronic feeding study with rats, no toxic effects were observed in rats given doses as high as 31 mg/kg/day, the highest dose tested. No toxic effects were observed in a chronic feeding study with dogs fed up to 500 mg/kg/day, the highest dose tested (8). Mice fed glyphosate for 90 days exhibited reduced body weight gains. The lifetime administration of very high amounts of glyphosate produced only a slight reduction of body weight and some microscopic liver and kidney changes. Blood chemistry, cellular components, and organ function were not affected even at the highest doses. Hens fed massive amounts over three days and again 21 days later showed no nerve related effects. > pmep.cce.cornell.edu But it's not a big deal in minor amounts. Mqurice
