A material part is supported, but the published wording goes beyond the record.
Monsanto said in February 2026 that regulators, including the US EPA and EU bodies, conclude that glyphosate-based herbicides can be used safely and are not carcinogenic.

Why this label
A material part is supported. EPA has repeatedly concluded that glyphosate is not likely to cause cancer, and the Supreme Court recited this in DurnellS2S3. The company's wording goes further than the EPA record in two ways. EPA's phrase is not likely to be carcinogenic, which is a weaker statement than are not carcinogenicS2. The human health part of EPA's 2020 interim decision was vacated by the Ninth Circuit in 2022 and the decision was withdrawn, so EPA's position now rests on its 2017 assessment and an update still in progressS2. IARC, a WHO agency, classified glyphosate as probably carcinogenicS1. IARC is not a regulator, but its view shows the conclusion is not uniform. EU positions were not checked against EU records here.
Current procedural position
Company statement of 17 February 2026S4. EPA human health risk assessment update in progress, completion anticipated in late 2026 as of 26 August 2026S2.
Record supporting the assessment
glyphosate-based herbicides can be used safely and are not carcinogenic
The EPA has repeatedly evaluated glyphosate and repeatedly concluded that glyphosate is not likely to cause cancer.
Conflicting or limiting record
The Ninth Circuit vacated the human health portion of EPA's ID.
In March 2015, IARC classified glyphosate as "probably carcinogenic to humans" (Group 2A).
Evidence score: 77 of 100
The score grades how well the record establishes this assessment. It is not a score of Bayer AG. Score = source authority + directness + corroboration + procedural accuracy + currency + reproducibility.
| Component | Points | Max | Reason |
|---|---|---|---|
| Source authorityIs the source competent to establish the proposition? | 25 | 30 | EPA and the Supreme Court are competent on the US regulatory position, and IARC on hazard classification. |
| DirectnessDoes the source state the proposition or only discuss adjacent facts? | 15 | 20 | The records state EPA's view and its limits, but not the EU part of the company's claim. |
| CorroborationDo independent records support the same material point? | 11 | 15 | The EPA page and the Supreme Court opinion agree on EPA's conclusion. |
| Procedural accuracyDoes the record settle the procedural state the claim describes? | 8 | 15 | EPA's registration review is still open after the 2022 withdrawal. |
| CurrencyHas the record been checked against later developments? | 9 | 10 | Checked against the EPA page updated 26 August 2026. |
| ReproducibilityCan a reader locate the passage and repeat the assessment? | 9 | 10 | All passages are on public official pages. |
| Total | 77 | 100 |
