What's more, the researchers found no difference between subjects who self-identified as people who actively ate organic and avoided GMOs and those who has no consumer preference.

"Our data - obtained using sophisticated and validated methods of analyses - strongly suggest that glyphosate does not bioaccumulate and is not present in human milk even when the mother has detectable glyphosate in her urine," McGuire added. "These findings emphasize the critical importance of carefully validating laboratory methods to the biological matrix of interest, especially when it is as complex as human milk."

McGuire presented these results and more at the recent Federation of American Societies for Experimental Biology Conference on July 23.
