The Samsel & Seneff study is a popular topic, and we’ve already received several questions about it. Dr. Kevin Folta, interim chair and associate professor in the Horticultural Sciences Department at the University of Florida, recently answered a similar question about the Samsel & Seneff study.
Here is an excerpt:
“…Relatively small amounts of glyphosate are applied as weeds emerge. These die and do not compete against emerging glyphosate-resistant crops. Glyphosate is amazingly nontoxic to humans or any other animals. Acute effects are seen only at relatively high doses. The LD50 (the dose that kills half of the rats that consume the dose) is about 5,000 mg/kg of body weight. In other words, if you weigh 200 pounds, you’d have to drink about two pounds of the 41% commercial concentrate to have a 50% chance of dying. Of course, it is not recommended—ask any of the hundreds of people who have tried to commit suicide by drinking it. It takes a good dose to cause problems. Look up ‘glyphosate’ and ‘suicide’ in PubMed.
