I recall that Mr Welch and the JBS were fighting the addition of flouride in public water supplies for many years.
Public is euphemism for government water. Do people still drink much government water? In many countries, that is never even considered. It's fine for the shower and toilet, but government cannot be trusted with anything children ingest. If parents want the tooth enamel protecting effects of fluoride antibacterial chemicals for their children, putting them in sugar free chewing gum would be far more effective.
