"In the EU, glyphosate residues in non-organic honey regulatory limits are 50 ng/g [27], the United States does not have a limit in honey. The limit in drinking water in the United States is 700 ng/mL; the reference dose is 1.75 mg/Kg/day; the One-Day Health Advisory level is 20 mg/L [28]. Also, it is widely known that like milk and olive oil, honey is one of the foods that is most commonly mislabeled and adulterated [29] providing yet another source of glyphosate contamination in honeys that, according to the bottle label, originated in non-GMO countries."


Table 3 in this study compares the ppm of glyphosate in US honey versus the other 17 countries tested. It appears that this survey determined US honey has notably higher concentrations than most other countries.  

As stated above, roundup in US water is limited to 700 ng/mL
