At least two fact-checking sites have investigated this study of Girl Scout cookies and have concluded that its findings are "misleading" and, basically, not as scary as they may sound. We spoke with a toxicologist, Joe Zagorski at Michigan State University's Center for Research on Ingredient Safety, who said something similar. Zagorski criticized the cookie study for its small sample size (25 cookies), its lack of peer review and other methodological issues. And he contended that the levels of heavy metals, aluminum and herbicide that the study found in the cookies are not dangerous.
