• TheIARCWGfoundanassociationbetweennon-Hodgkinlymphomaandglyphosatebasedontheavailablehumanevidence.

• TheIARCWGfoundsignificantcarcinogeniceffectsinlaboratoryanimalsfortwotumortypesintwomousestudiesandbenigntumorsintworatstudies.

• Finally,theIARCWGconcludedstrongevidenceofgenotoxicityandoxidativestressforglyphosate,entirelyfrompubliclyavailableresearch,includingfindingsofDNAdamageintheperipheralbloodofexposedhumans.

IntheirRAR,BfRconcluded(Vol.1,p.160)“classificationandlabelingforcarcinogenesisisnotwarranted”and“glyphosateisdevoidofgenotoxicpotential”.

• BfRagreedwiththeIARConlimitedevidenceinhumansbutthendismissedtheassociationas“insufficientlyconsistent”withnojustification.

• UsinganinappropriatehistoricalcontroldatasetinanincorrectmannerandignoringestablishedOECDguidelinescitedintheirreport,BfRdismissedevidenceofrenaltumorsin3mousestudies,hemangiosarcomain2mousestudiesandmalignantlymphomain2mousestudies.Thus,BfRincorrectlydiscardedalloftheglyphosate-inducedcarcinogenicfindingsinanimalsaschanceoccurrences.

• TheBfRignoredimportantlaboratoryandhumanevidenceofgenotoxicity.

• TheBfRconfirmedthatglyphosateinducesoxidativestressanddismissedthisfindingforlackofanyotherfindingbecausetheyhaddismissedalloftheotherevidence.

Themostparsimoniousscientificexplanationofthecancersseeninhumansandlaboratoryanimalssupportedbythemechanisticdataisthatglyphosateisaprobablehumancarcinogen.Onthebasisofthisconclusionandintheabsenceof

contraryevidence,itisreasonabletoconcludethatglyphosateformulationsshouldalsobeconsideredprobablehumancarcinogens.WebelievethattheargumentspromotedbytheBfRtonegatethehuman,animalandmechanisticevidencearefundamentallyandscientificallyflawedandshouldberejected.Westronglyobjecttothealmostnon-existentweightgiventostudiesfromtheliteraturebytheBfRandthestrongrelianceonnon-publiclyavailabledatainalimitedsetofassaysthatdefinetheminimumdatanecessaryfortheapprovalofapesticide.WebelievethattheIARCWGevaluationofprobablycarcinogenictohumansaccuratelyreflectstheresultsofthepublishedscientificliteratureonglyphosateand,onthefaceofit,theunpublishedstudiestowhichtheBfRrefers.Conversely,theBfRevaluation,andconsequentlytheEFSAevaluation,donotreflecttheavailablescience.Thus,repeatingourearlierrequest,weurgeyouandtheEuropeanCommissiontodisregardtheflawedEFSAfindingonglyphosateinyourformulationofglyphosatehealthandenvironmentalpolicyforEuropeandtocallforatransparent,openandcrediblereviewofthescientificliterature.TheviewsexpressedinthisletteraretheopinionofthescientistswhoarelistedbelowandDONOTimplyanendorsementorsupportfortheseopinionsbyanyorganizationstowhichtheyareaffiliated.Sincerely,Prof.ChristopherJ.Portier(CorrespondingAuthor)SeniorContributingScientist,EnvironmentalDefenseFund,Washington,DCVisitingProfessor,MaastrichtUniversity,Maastricht,TheNetherlandsAdjunctProfessor,EmoryUniversity,Atlanta,Georgia,USAHonoraryProfessor,UniversityofQueensland,Brisbane,Queensland,AustraliaFormerDirector,NationalCenterforEnvironmentalHealth,Atlanta,USAFormerDirector,AgencyforToxicSubstancesandDiseaseRegistry,Atlanta,USAFormerAssociateDirector,USNationalToxicologyProgram,RTP,NC,USACH-3600Thun,Switzerlandcportier@mac.com+41796057958BruceArmstrongMBBS,DPhil(Oxon),FFAPHM,FAAEmeritusProfessorSydneySchoolofPublicHealthTheUniversityofSydney,AustraliaDistinguishedProfessorBruceCBaguleyAucklandCancerSocietyResearchCentreTheUniversityofAucklandAuckland,NewZealandProf.Dr.med.XaverBaurInstituteforOccupationalMedicine
