IN RE: ROUNDUP PRODUCTS MDL No. 2741 LIABILITY LITIGATION Case No. 16-md-02741-VC This document relates to: SUGGESTION OF REMAND TO TRANSFEROR COURT Vander Groef et al. v. Monsanto Co., Case No. 3:19-cv-07858-VC
This suggestion of remand is for Plaintiff Sally Vander Groef, whose case was transferred to this MDL from the District of New Jersey. I In March 2015, the International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans.” The classification stemmed from scientific studies that found an association between glyphosate exposure and non-Hodgkin lymphoma (NHL). Glyphosate is the active ingredient in Monsanto’s widely used weedkiller Roundup, and the IARC classification prompted people with NHL to file lawsuits against Monsanto in federal and state courts across the country, primarily alleging that Monsanto failed to warn them about the cancer risks posed by Roundup. In October 2016, the Panel created this MDL for federal court cases in which plaintiffs allege that Roundup caused their NHL. In re Roundup Products Liability Litigation, 214 F. Supp. 3d 1346 (J.P.M.L. 2016). To date, several thousand individual cases have been filed in judicial districts around the country and transferred to the MDL. Bayer (which now owns Monsanto) began to settle these cases in June 2020. The company reached separate settlement agreements with individual law firms to resolve the cases being handled by those firms. By this point, well over half the cases in the MDL are subject to agreements with firms. But for each individual case, the settlement is subject to approval by the plaintiff represented by the firm that signed the agreement. Meanwhile, the cases in the MDL that are not subject to a settlement agreement continue to be worked up for trial. This is happening in waves, with a litigation schedule (through summary judgment) being set for each wave. Monsanto does not consent to cases from other districts being tried here in the Northern District of California. Thus far, most cases in a given wave have settled prior to summary judgment. Occasionally, a summary judgment ruling is necessary, but then the cases settle shortly after I rule, and before I can suggest that the case be remanded for trial. And on rare occasions, the case does not settle even after I rule on summary judgment. This case, Vander Groef et al. v. Monsanto, was originally filed in the District of New Jersey. It became part of the seventh wave. Discovery is complete, I have denied Monsanto’s summary judgment motion, and the case did not settle immediately following my rulings. Accordingly, the case is ready for trial, and I suggest that the Panel remand it to the District of New Jersey. What follows is a summary of the pretrial proceedings and guidance for the judge who will be trying the case. II In the MDL, the proceedings were bifurcated and we focused first on general causation— that is, whether Roundup is capable of causing NHL at exposure levels that people can be expected to experience. Both sides (with the plaintiffs represented by leadership counsel) presented expert testimony at Daubert hearings. I ruled that some of the plaintiffs’ experts satisfied Daubert, and that a reasonable jury relying on their testimony could conclude that Roundup is capable of causing NHL. In re Roundup Products Liability Litigation, 390 F. Supp. 3d 1102 (N.D. Cal. 2018) (Pretrial Order No. 45, Dkt. No. 1596). There is a video recording of the Daubert hearings on general causation; they can be viewed at https://www.uscourts.gov/cameras-courts/re-roundup-products-liability-litigation. We then worked up three bellwether cases for trial. All three involved claims under California law. After discovery, Monsanto moved for summary judgment on the question of specific causation—that is, whether a reasonable jury could conclude that Roundup caused NHL in these three particular plaintiffs. Following more Daubert hearings, I denied Monsanto’s motion for summary judgment on specific causation, ruling that a reasonable jury could find that Roundup caused the plaintiffs’ NHL. In re Roundup Products Liability Litigation, 358 F. Supp. 3d 956 (N.D. Cal. 2019) (Pretrial Order No. 85, Dkt. No. 2799).1 However, I ruled that certain portions of the testimony given by the plaintiffs’ experts at the Daubert hearings crossed into the realm of junk science and could not be repeated to the jury at trial. Id. at 961–62. The first of the three bellwether cases, Hardeman v. Monsanto, went to trial in February 2019. The core claims in Harris are similar to the claims that were brought by Hardeman— namely, that Monsanto failed to warn of the risk that Roundup could cause NHL and that Roundup is defective because it causes NHL. The Hardeman trial was bifurcated, with the first phase focusing solely on causation. See Pretrial Order No. 61 (Dkt. No. 2406). A jury concluded, after several days of deliberation, that Roundup caused Hardeman’s NHL. The second phase of the trial focused primarily on damages. The jury awarded $5,066,667 in compensatory damages and $75,000,000 in punitive damages. The punitive damages award was based on evidence presented at trial that Monsanto was more concerned with tamping down safety inquiries and controlling public opinion around Roundup than it was with ensuring that its product is safe. California law provides for punitive damages where a defendant acts “with a willful and conscious disregard of the rights or safety of others.” California Civil Code § 3294(c)(1). After trial, I reduced the punitive damages award to $20,000,000 to comport with due process.

Cal. 2019) 1 All Pretrial Orders cited here are docket entries in In re Roundup Products Liability Litigation, Case No. 3:16-md-02741-VC. (Pretrial Order No. 160, Dkt. No. 4576). The verdict and post-trial rulings were affirmed by the Ninth Circuit Court of Appeals. Hardeman v. Monsanto, 997 F.3d 941 (9th Cir. 2021). Monsanto filed a cert petition with the U.S. Supreme Court, primarily arguing that Hardeman’s state law claims are preempted by federal law. The Supreme Court denied the petition in June 2022. However, it bears noting that a circuit split has now developed on the federal preemption question, with the Third Circuit having disagreed with the Ninth Circuit’s ruling in Hardeman. A cert petition on that case is now pending. Durnell v. Monsanto Co., No. ED 112410 (Mo. Ct. App. Feb. 11, 2025), petition for cert. filed (April 4, 2025). If the Court grants cert, it will be worth discussing with the parties whether the case should be stayed pending a ruling on preemption. Following the Hardeman verdict, the two remaining bellwethers settled. Meanwhile, as previously mentioned, we established a system by which cases in the MDL would be worked up for trial in waves. In January 2020, I issued rulings on dispositive motions in the Wave 1 cases. I also concluded that it would serve the interest of judicial economy for me to rule on non- dispositive evidentiary motions that related to causation (for example, a motion to prevent a particular expert from making a particular point to the jury about causation). I concluded that other non-dispositive motions to limit or exclude testimony were better left to the judge who would be trying the cases, so I denied those motions without prejudice. See Pretrial Order No. 202 (Dkt. No. 9143). For specific causation, I simply incorporated my ruling from the bellwether cases and applied it to the Wave 1 cases, thereby denying Monsanto’s motion to exclude specific causation experts while identifying certain claims that the experts would not be permitted to make at trial. See Pretrial Order No. 85 (Dkt. No. 2799); Pretrial Order No. 203 (Dkt. No. 9144). I also issued a separate ruling limiting the testimony of a different plaintiff’s expert, Dr. Sawyer. Pretrial Order No. 201 (Dkt. No. 9142). I followed the same approach for subsequent waves. The Vander Groef case is part of the Wave 7 cases. Monsanto filed Daubert motions relating to two experts in Vander Groef: Dr. Dennis Weisenburger, both a general causation expert and plaintiff’s specific causation expert, and Dr. Martyn Smith, a general causation expert. I denied the motion to exclude Dr. Weisenburger and granted the motion to exclude Dr. Smith. See Dkt. No. 19284; Pretrial Order No. 333 (Dkt. No. 21305). In short, I ruled that Weisenburger had reliably performed the “differential diagnosis” necessary to opine that Vander Groef’s deceased husband’s NHL was caused by his exposure to Roundup. One issue that came up during preparation for the bellwether trials was whether the parties should be permitted to present general causation testimony from someone other than an expert whose opinions were tested during the general causation phase of the MDL. In particular, Monsanto argued that it should not be limited to using those experts, and that its specific causation experts (who were not part of the general causation phase) should be permitted to offer a general opinion that Roundup does not cause NHL (in addition to their specific opinion that Roundup did not cause NHL in a particular plaintiff). Although I agreed with Monsanto that it typically will make sense for a specific causation expert to include a general opinion about whether Roundup is a risk factor for NHL (assuming the specific causation expert is also qualified to give a general causation opinion), I rejected Monsanto’s request as it related to the bellwether cases, because the parties and the Court had been operating under the assumption that general causation testimony at the bellwether trials would be from the experts who passed Daubert during the general causation phase. Pretrial Order No. 81 (Dkt. No. 2775). However, I subsequently ruled that it would be appropriate for specific causation experts to include in their opinions the kind of testimony given by the general causation experts during the general causation phase of the MDL, thus potentially obviating the need to call separate witnesses on general causation. See Pretrial Order No. 271 (Dkt. No. 14489). The parties will need to refile motions in limine unrelated to causation, and the trial judge will need to consider those motions. My in limine rulings from the Hardeman trial may serve as guidance. See generally Pretrial Order No. 81 (Dkt. No. 2775). My post-trial ruling explaining the evidentiary issues that came up during trial may also be helpful. See generally Pretrial Order No. 159. The Ninth Circuit’s ruling in Hardeman provides helpful guidance regarding damages and jury instructions (including an instructional error—albeit a harmless one—that the Circuit identified in the Hardeman case). Attached as Appendix A to this order is a longer list of documents that the trial judge may wish to read in preparation for trial. The Clerk of Court is directed to provide a copy of the suggestion of remand to the Clerk of the United States Judicial Panel on Multidistrict Litigation and the Clerk of the District of New Jersey.

Please see: https://www.cand.uscourts.gov/judges/chhabria-vince- vc/in-re-roundup-products-liability-litigation-mdl-no-2741 Pretrial Order No. 236 (Order re Motion to Establish Holdback Percentage): This ruling on fees is not directly relevant but it describes the history of the MDL. Pretrial Order No. 45 (General Causation): This order denies summary judgment for Monsanto on general causation grounds and applies the Daubert test to general causation experts. I recommend the trial judge skim this ruling to develop general familiarity with the science and to help understand the decision by the IARC to classify glyphosate as a probable carcinogen. Pretrial Order No. 85 (Specific Causation): This ruling denies summary judgment for Monsanto on specific causation grounds and sets parameters for testimony by specific causation experts. Pretrial Order No. 101 (Summary Judgment): This ruling rejects various arguments by Monsanto (other than those relating to causation) for summary judgment. Pretrial Order No. 61 (Bifurcation): This ruling explains the rationale for bifurcating the Hardeman trial. Pretrial Order No. 70 (Jury Questionnaire): This is the questionnaire we submitted to prospective jurors in advance of the Hardeman trial. Pretrial Order No. 81 (Ruling on Motions in Limine for the Bellwether Trials): This ruling discusses many issues that will come up in any Roundup trial. Pretrial Order No. 108 (Jury Instructions on Phase 1 of the Hardeman Trial) Pretrial Order No. 139 (Jury Instructions on Phase 2 of the Hardeman Trial) Pretrial Order No. 159 (Denying Monsanto’s Post-Trial Motions Relating to Issues Other Than Damages): This ruling discusses evidentiary issues that came up at the Hardeman trial, some of which will likely recur in any Roundup trial. Pretrial Order No. 160 (Ruling on Post-Trial Motions Relating to Damages): This ruling will be relevant if there is a damages award and a post-trial motion to reduce the award. Ninth Circuit Ruling on Preemption, Damages, Evidentiary Issues, and Instructional Issues Hardeman v. Monsanto, 997 F.3d 941 (9th Cir. 2021): This ruling is generally helpful, but in particular the trial judge should make sure to review the discussion of jury instructions under California law. After trial, in the event of a damages award, the Ninth Circuit’s discussion of punitive damages will be important. UNITED STATES DISTRICT COURT NORTHERN DISTRICT OF CALIFORNIA

This suggestion of remand is for Plaintiffs Bakri El-Hakam and Mary El-Hakam, whose case was transferred to this MDL from the Southern District of Texas. I In March 2015, the International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans.” The classification stemmed from scientific studies that found an association between glyphosate exposure and non-Hodgkin lymphoma (NHL). Glyphosate is the active ingredient in Monsanto’s widely used weedkiller Roundup, and the IARC classification prompted people with NHL to file lawsuits against Monsanto in federal and state courts across the country, primarily alleging that Monsanto failed to warn them about the cancer risks posed by Roundup.

Monsanto filed Daubert motions relating to three experts in El-Hakam: Dr. Dennis Weisenburger, both a general causation expert and plaintiff’s specific causation expert, Dr. Chadi Nabhan, a general causation and damages expert, and Dr. Martyn Smith, a general causation expert. I denied the motion to exclude Dr. Weisenburger, denied in part and granted the part the motion to exclude Dr. Nabhan, and granted the motion to exclude Dr. Smith. See Dkt. No. 19284; Dkt. No. 20021; Pretrial Order No. 333 (Dkt. No. 21305). In short, I ruled that Weisenburger had reliably performed the “differential diagnosis” necessary to opine that Mr. El- Hakam’s NHL was caused by his exposure to Roundup. I also ruled that Nabhan did not offer reliable causation testimony, while leaving his damages testimony to be evaluated by the trial court. One issue that came up during preparation for the bellwether trials was whether the parties should be permitted to present general causation testimony from someone other than an expert whose opinions were tested during the general causation phase of the MDL. In particular, Monsanto argued that it should not be limited to using those experts, and that its specific causation experts (who were not part of the general causation phase) should be permitted to offer a general opinion that Roundup does not cause NHL (in addition to their specific opinion that Roundup did not cause NHL in a particular plaintiff). Although I agreed with Monsanto that it typically will make sense for a specific causation expert to include a general opinion about whether Roundup is a risk factor for NHL (assuming the specific causation expert is also qualified to give a general causation opinion), I rejected Monsanto’s request as it related to the bellwether cases, because the parties and the Court had been operating under the assumption that general causation testimony at the bellwether trials would be from the experts who passed Daubert during the general causation phase. Pretrial Order No. 81 (Dkt. No. 2775). However, I subsequently ruled that it would be appropriate for specific causation experts to include in their opinions the kind of testimony given by the general causation experts during the general causation phase of the MDL, thus potentially obviating the need to call separate witnesses on general causation. See Pretrial Order No. 271 (Dkt. No. 14489). The parties will need to refile motions in limine unrelated to causation, and the trial judge will need to consider those motions. My in limine rulings from the Hardeman trial may serve as guidance. See generally Pretrial Order No. 81 (Dkt. No. 2775). My post-trial ruling explaining the evidentiary issues that came up during trial may also be helpful. See generally Pretrial Order No. 159. The Ninth Circuit’s ruling in Hardeman provides helpful guidance regarding damages and jury instructions (including an instructional error—albeit a harmless one—that the Circuit identified in the Hardeman case). Attached as Appendix A to this order is a longer list of documents that the trial judge may wish to read in preparation for trial. The Clerk of Court is directed to provide a copy of the suggestion of remand to the Clerk of the United States Judicial Panel on Multidistrict Litigation and the Clerk of the Southern District of Texas.

IN RE: ROUNDUP PRODUCTS MDL No. 2741 LIABILITY LITIGATION Case No. 16-md-02741-VC This document relates to: SUGGESTION OF REMAND TO TRANSFEROR COURT Romano v. Monsanto Co., Case No. 3:20-cv-06194-VC
This suggestion of remand is for Plaintiff Nathan P. Romano, whose case was transferred to this MDL from the Northern District of West Virginia. I In March 2015, the International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans.” The classification stemmed from scientific studies that found an association between glyphosate exposure and non-Hodgkin lymphoma (NHL). Glyphosate is the active ingredient in Monsanto’s widely used weedkiller Roundup, and the IARC classification prompted people with NHL to file lawsuits against Monsanto in federal and state courts across the country, primarily alleging that Monsanto failed to warn them about the cancer risks posed by Roundup. In October 2016, the Panel created this MDL for federal court cases in which plaintiffs allege that Roundup caused their NHL. In re Roundup Products Liability Litigation, 214 F. Supp. 3d 1346 (J.P.M.L. 2016). To date, several thousand individual cases have been filed in judicial districts around the country and transferred to the MDL. Bayer (which now owns Monsanto) began to settle these cases in June 2020. The company reached separate settlement agreements with individual law firms to resolve the cases being handled by those firms. By this point, well over half the cases in the MDL are subject to agreements with firms. But for each individual case, the settlement is subject to approval by the plaintiff represented by the firm that signed the agreement. Meanwhile, the cases in the MDL that are not subject to a settlement agreement continue to be worked up for trial. This is happening in waves, with a litigation schedule (through summary judgment) being set for each wave. Monsanto does not consent to cases from other districts being tried here in the Northern District of California. Thus far, most cases in a given wave have settled prior to summary judgment. Occasionally, a summary judgment ruling is necessary, but then the cases settle shortly after I rule, and before I can suggest that the case be remanded for trial. And on rare occasions, the case does not settle even after I rule on summary judgment. This case, Romano v. Monsanto, was originally filed in the Northern District of West Virginia. It became part of the seventh wave. Discovery is complete, I have denied Monsanto’s summary judgment motion, and the case did not settle immediately following my rulings. Accordingly, the case is ready for trial, and I suggest that the Panel remand it to the Northern District of West Virginia. What follows is a summary of the pretrial proceedings and guidance for the judge who will be trying the case. II In the MDL, the proceedings were bifurcated and we focused first on general causation— that is, whether Roundup is capable of causing NHL at exposure levels that people can be expected to experience. Both sides (with the plaintiffs represented by leadership counsel) presented expert testimony at Daubert hearings. I ruled that some of the plaintiffs’ experts satisfied Daubert, and that a reasonable jury relying on their testimony could conclude that Roundup is capable of causing NHL. In re Roundup Products Liability Litigation, 390 F. Supp. 3d 1102 (N.D. Cal. 2018) (Pretrial Order No. 45, Dkt. No. 1596). There is a video recording of the Daubert hearings on general causation; they can be viewed at https://www.uscourts.gov/cameras-courts/re-roundup-products-liability-litigation. We then worked up three bellwether cases for trial. All three involved claims under California law. After discovery, Monsanto moved for summary judgment on the question of specific causation—that is, whether a reasonable jury could conclude that Roundup caused NHL in these three particular plaintiffs. Following more Daubert hearings, I denied Monsanto’s motion for summary judgment on specific causation, ruling that a reasonable jury could find that Roundup caused the plaintiffs’ NHL. In re Roundup Products Liability Litigation, 358 F. Supp. 3d 956 (N.D. Cal. 2019) (Pretrial Order No. 85, Dkt. No. 2799).1 However, I ruled that certain portions of the testimony given by the plaintiffs’ experts at the Daubert hearings crossed into the realm of junk science and could not be repeated to the jury at trial. Id. at 961–62. The first of the three bellwether cases, Hardeman v. Monsanto, went to trial in February 2019. The core claims in Harris are similar to the claims that were brought by Hardeman— namely, that Monsanto failed to warn of the risk that Roundup could cause NHL and that Roundup is defective because it causes NHL. The Hardeman trial was bifurcated, with the first phase focusing solely on causation. See Pretrial Order No. 61 (Dkt. No. 2406). A jury concluded, after several days of deliberation, that Roundup caused Hardeman’s NHL. The second phase of the trial focused primarily on damages. The jury awarded $5,066,667 in compensatory damages and $75,000,000 in punitive damages. The punitive damages award was based on evidence presented at trial that Monsanto was more concerned with tamping down safety inquiries and controlling public opinion around Roundup than it was with ensuring that its product is safe. California law provides for punitive damages where a defendant acts “with a willful and conscious disregard of the rights or safety of others.” California Civil Code § 3294(c)(1). After trial, I reduced the punitive damages award to $20,000,000 to comport with due process. See In re Roundup Products Liability Litigation, 385 F. Supp. 3d 1042 (N.D. Cal. 2019) 1 All Pretrial Orders cited here are docket entries in In re Roundup Products Liability Litigation, Case No. 3:16-md-02741-VC. (Pretrial Order No. 160, Dkt. No. 4576). The verdict and post-trial rulings were affirmed by the Ninth Circuit Court of Appeals. Hardeman v. Monsanto, 997 F.3d 941 (9th Cir. 2021). Monsanto filed a cert petition with the U.S. Supreme Court, primarily arguing that Hardeman’s state law claims are preempted by federal law. The Supreme Court denied the petition in June 2022. However, it bears noting that a circuit split has now developed on the federal preemption question, with the Third Circuit having disagreed with the Ninth Circuit’s ruling in Hardeman. A cert petition on that case is now pending. Durnell v. Monsanto Co., No. ED 112410 (Mo. Ct. App. Feb. 11, 2025), petition for cert. filed (April 4, 2025). If the Court grants cert, it will be worth discussing with the parties whether the case should be stayed pending a ruling on preemption. Following the Hardeman verdict, the two remaining bellwethers settled. Meanwhile, as previously mentioned, we established a system by which cases in the MDL would be worked up for trial in waves. In January 2020, I issued rulings on dispositive motions in the Wave 1 cases. I also concluded that it would serve the interest of judicial economy for me to rule on non- dispositive evidentiary motions that related to causation (for example, a motion to prevent a particular expert from making a particular point to the jury about causation). I concluded that other non-dispositive motions to limit or exclude testimony were better left to the judge who would be trying the cases, so I denied those motions without prejudice. See Pretrial Order No. 202 (Dkt. No. 9143). For specific causation, I simply incorporated my ruling from the bellwether cases and applied it to the Wave 1 cases, thereby denying Monsanto’s motion to exclude specific causation experts while identifying certain claims that the experts would not be permitted to make at trial. See Pretrial Order No. 85 (Dkt. No. 2799); Pretrial Order No. 203 (Dkt. No. 9144). I also issued a separate ruling limiting the testimony of a different plaintiff’s expert, Dr. Sawyer. Pretrial Order No. 201 (Dkt. No. 9142). I followed the same approach for subsequent waves. The Romano case is part of the Wave 7 cases. Monsanto filed Daubert motions relating to three experts in Romano: Dr. Dennis Weisenburger, both a general causation expert and plaintiff’s specific causation expert, Dr. Chadi Nabhan, a general causation and damages expert, and Dr. Martyn Smith, a general causation expert. I denied the motion to exclude Dr. Weisenburger, denied in part and granted the part the motion to exclude Dr. Nabhan, and granted the motion to exclude Dr. Smith. See Dkt. No. 19284; Dkt. No. 20021; Pretrial Order No. 333 (Dkt. No. 21305). In short, I ruled that Weisenburger had reliably performed the “differential diagnosis” necessary to opine that Romano’s NHL was caused by his exposure to Roundup. I also ruled that Nabhan did not offer reliable causation testimony, while leaving his damages testimony to be evaluated by the trial court. One issue that came up during preparation for the bellwether trials was whether the parties should be permitted to present general causation testimony from someone other than an expert whose opinions were tested during the general causation phase of the MDL. In particular, Monsanto argued that it should not be limited to using those experts, and that its specific causation experts (who were not part of the general causation phase) should be permitted to offer a general opinion that Roundup does not cause NHL (in addition to their specific opinion that Roundup did not cause NHL in a particular plaintiff). Although I agreed with Monsanto that it typically will make sense for a specific causation expert to include a general opinion about whether Roundup is a risk factor for NHL (assuming the specific causation expert is also qualified to give a general causation opinion), I rejected Monsanto’s request as it related to the bellwether cases, because the parties and the Court had been operating under the assumption that general causation testimony at the bellwether trials would be from the experts who passed Daubert during the general causation phase. Pretrial Order No. 81 (Dkt. No. 2775). However, I subsequently ruled that it would be appropriate for specific causation experts to include in their opinions the kind of testimony given by the general causation experts during the general causation phase of the MDL, thus potentially obviating the need to call separate witnesses on general causation. See Pretrial Order No. 271 (Dkt. No. 14489). The parties will need to refile motions in limine unrelated to causation, and the trial judge will need to consider those motions. My in limine rulings from the Hardeman trial may serve as guidance. See generally Pretrial Order No. 81 (Dkt. No. 2775). My post-trial ruling explaining the evidentiary issues that came up during trial may also be helpful. See generally Pretrial Order No. 159. The Ninth Circuit’s ruling in Hardeman provides helpful guidance regarding damages and jury instructions (including an instructional error—albeit a harmless one—that the Circuit identified in the Hardeman case).

IN RE: ROUNDUP PRODUCTS MDL No. 2741 LIABILITY LITIGATION Case No. 16-md-02741-VC This document relates to: SUGGESTION OF REMAND TO TRANSFEROR COURT Daulton et al. v. Monsanto Co., Case No. 3:20-cv-08518-VC
This suggestion of remand is for Plaintiff Renee Theresa Daulton, whose case was transferred to this MDL from the District of Minnesota. I In March 2015, the International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans.” The classification stemmed from scientific studies that found an association between glyphosate exposure and non-Hodgkin lymphoma (NHL).
