A review frequently cited by people asserting that an ingredient in the Roundup weed killer is not harmful has been retracted.
The Regulatory Toxicology and Pharmacology, an Elsevier journal, said on Dec. 5 that it retracted the review, safety evaluation, and risk assessment of the herbicide Roundup and its active ingredient, glyphosate, for humans. It cited guidelines from the Committee on Publication Ethics, or COPE, which include recommending retractions if unethical research practices or undisclosed conflicts of interest are discovered.
