ConexiantToxic Metals, Glyphosate Found in Girl Scout Cookies

A recent laboratory investigation of Girl Scout cookies revealed widespread contamination with glyphosate and toxic metals across multiple product lines. The study, conducted by MIT researchers and published on GMOScience.org, analyzed 25 cookie samples from three states, documenting consistent presence of herbicide residue and heavy metals, with several samples exceeding EPA safety thresholds.


Key Points:

  • All tested samples (100%, n=25) contained detectable levels of glyphosate, with concentrations ranging from 13.57 ppb in Peanut Butter Patties to 111.07 ppb in Thin Mints – levels reportedly 334 times higher than recommended safety thresholds according to Purdue University research.
  • Heavy metal contamination was present in 88% of samples (n=22/25), with testing revealing presence of aluminum, arsenic, cadmium, lead, and mercury. Notably, 76% of samples exceeded EPA water safety limits for cadmium (>5 ppb).
  • Lead contamination was detected in 96% of samples, with Peanut Butter Patties showing the highest concentrations at 42.5 ppb for lead and 27.5 ppm (27,500 ppb) for aluminum.
  • The study examined products from both major manufacturers (ABC Bakers and Little Brownie Bakers) across three states: California, Iowa, and Louisiana, suggesting widespread distribution of contaminated products.
  • The researchers estimate that Girl Scouts USA’s annual wheat flour purchasing power ($16 million) could influence agricultural practices if redirected toward organic and regenerative farming methods.

“The health implications of toxic substances in [Girl Scout] cookies extend beyond the immediate impact on our girls and affect the public at large. Identifying and eliminating the sources of these toxic metals is imperative to safeguarding public health.”
