Aluminum37 ppmof 0.2 ppm

Over the limit — 185×FDA bottled-water Standard of Quality (secondary/aesthetic), 21 CFR 165.110(b) — 0.2 mg/L. NOTE: this is a bottled-water level; it is not an FDA limit for aluminum in solid foods, where no comparable federal limit exists.

Glyphosate12.8 ppbof 160 ppb

8% of the limitEWG children's health benchmark 160 ppb (0.01 mg/day in a 60 g serving). EPA tolerance for glyphosate on oats is far higher at 30 ppm (30,000 ppb), 40 CFR 180.364.

Aminomethylphosphonic Acid2.21 ppbof 160 ppb

1% of the limitNo regulator publishes a food concentration limit for AMPA alone. EFSA (2023 glyphosate conclusion) and JMPR state glyphosate's toxicological reference values apply to AMPA (shared group ADI), so Tallow applies glyphosate's benchmark: EWG children's health benchmark 160 ppb (0.01 mg/day in a 60 g serving). Water-only references: EU drinking water 0.1 ug/L per pesticide/metabolite; Minnesota MDH guidance 1,000 ppb.

Common questions

Is Kellogg's Corn Flakes Breakfast Cereal healthy?
