Bayer lawsuit: Plaintiff witness rejects EPA Roundup safety assessment as next glyphosate-cancer trial begins

Bio-statisticianChristopher Portier testified in latest glyphosate-cancer trial on April 2, 2019

At the start of testimony in what looks to be a long and contentious trial over whether [Bayer’s herbicide] Roundup caused the cancer of an elderly couple, a cancer-risk expert said he would give the U.S. Environmental Protection Agency an “F” on its report deeming glyphosate, one of the main agrochemicals in Roundup, noncarcinogenic.

“I’d fail them,” Dr. Christopher Portier testified.

The bio-statistician challenged the EPA’s glyphosate issue paper from 2016 because, among other issues, it failed to disclose that one of the studies it used had been invalidated due to scientific fraud.

The study, conducted in 1973 by the now-defunct Industrial Bio-Test (IBT) Laboratories, found no statistically significant increase in tumors in albino mice after 18 months of feeding them glyphosate. That study was invalidated by the EPA itself after IBT was caught in an audit having falsified its data.
