In November, #RFKJr, now the federal #health secretary, said that the #Trump administration would “advise all U.S. water systems to remove #fluoride from public water” because of potential health risks. Anti-fluoridation bills have also been introduced in NorthDakota, Tennessee & Montana.

The #law, which was signed by #Republican Gov #SpencerCox on March 27 & will go into effect on May 7, comes amid renewed scrutiny of #fluoride, a mineral that has been widely added to US #DrinkingWater since 1945 to prevent cavities. Controversy over the safety of water fluoridation has intensified in recent years, driven in part by #ConspiracyTheories & by growing resistance to #PublicHealth interventions since the #pandemic.
