Sales of products carrying the Glyphosate Residue Free (GRF) certification have increased 180% year over year to $2.8 billion, according to new data reported November 10 by The Detox Project. The figures, attributed to retail market research firm SPINS, point to growing commercial interest in independently tested food ingredients and finished products as manufacturers respond to demand for greater supply-chain transparency.

The reported sales represent products carrying the certification, rather than revenue generated by the certification program itself. The previous SPINS data, covering the third quarter of 2025, placed sales at approximately $1 billion. The certification, administered by The Detox Project, now appears across more than a dozen product categories, including oats, cereals, grains, supplements, plant-based beverages, pasta, snacks, oils and pet food. Brands carrying the seal include Oatly, Chobani, Califia Farms, Jovial and Kettle & Fire.

The program requires products to undergo testing by third-party laboratories accredited to ISO/IEC 17025, using analytical methods capable of detecting low glyphosate concentrations. The certification standard generally requires no detectable residues at a laboratory detection limit of approximately 0.01 parts per million (ppm), with testing conducted at least three times annually and additional spot checks. It covers individual ingredients as well as single- and multi-ingredient finished products.

However, a non-detect result is not the same as proof that glyphosate was never used during production. It indicates that residues were not detected in the tested sample at the method’s detection limit. This also differs from federal pesticide regulation, which establishes commodity-specific residue tolerances rather than requiring all foods to have no detectable residues. The FDA’s fiscal 2024 monitoring report, released in September 2026, found that pesticide residues in the U.S. food supply were generally within EPA tolerances.

The distinction is relevant as EPA continues its review of glyphosate. In August 2026, the agency released an updated scientific literature search to inform a revised human health risk assessment, including potential dietary exposure from food and water. The assessment is scheduled for completion in late 2026.
