Quaker Old Fashioned Oats
Summary
Quaker Old Fashioned Oats scores 23/100. EWG's February 2024 chlormequat study detected the pesticide at ~290 ppb — the highest of any oat product in the published batch. Chlormequat is a plant growth regulator linked to reduced fertility and developmental toxicity in animal studies (Reproductive Toxicology 2020); it is not approved for use on food crops grown in the U.S., so its presence indicates pre-harvest spraying on imported or feed-grade oats. This sits on top of the EWG 2023 finding of 261.4 ppb glyphosate in the same product line — a double-pesticide contamination story on what would otherwise be a single-ingredient NOVA 1 whole food.
At a glance
Contaminants 2
Source: EWG
Glyphosate 261.4 ppb High
Detected at a high level — at or above health-based benchmarks such as EWG's 160 ppb children's-health benchmark. Regular exposure at this level is a genuine health concern. Glyphosate is classified as a probable human carcinogen by IARC, and glyphosate-residue-free supply chains exist — so its presence reflects ingredient sourcing.
EWG 2023 testing detected glyphosate at up to 261.4 ppb. This is among the highest levels found in any oat product tested.
Chlormequat ~290 ppb High
Detected at a high level — at or above health-based exposure limits. Regular exposure at this level is a genuine health concern. Chlormequat is a plant growth regulator (PGR) used to shorten cereal stalks pre-harvest. Animal studies link chlormequat exposure to reduced fertility, delayed puberty, and developmental toxicity (Environmental Health Perspectives 2018; Reproductive Toxicology 2020). Chlormequat is not approved for use on food crops grown in the U.S., so its presence in this product indicates pre-harvest spraying on imported (likely Canadian or European) oats. There is no FDA tolerance for chlormequat in oat-based foods sold in the U.S.
EWG's February 2024 study detected chlormequat chloride at ~290 ppb in this product. EWG detected chlormequat in 80% of urine samples from a U.S. population in 2023.
