A former Purdue University professor says it will be a few more months before he can support his claim that Roundup Ready technology is responsible for the proliferation of a previously unknown microscopic organism he says causes plant diseases and livestock abortions. A sample of the organism was sent to a lab in March for sequencing so the organism could have its characteristics clearly identified, said Don Huber, the retired Purdue professor. However, a contaminant was found in the sample, ”so we had to take more time to get the material that is required,” Huber said.
