State health department investigators interviewed patrons of a restaurant where the outbreak first became manifest and obtained blood and urine samples for measurement of fluoride levels.
State health department staff conducted a random sample telephone survey of community households.
Public health environmentalists obtained water and ice samples from the restaurant and tap water samples from a household close to one of the town's water treatment plants for analysis.
Health department investigators and town water department officials inspected the fluoridation system at the town's main water treatment plant.
Thirty-four of 62 restaurant patrons reported acute gastrointestinal illness over a 24-hour period.
Twenty of 61 households that used the community water supply reported one or more residents with acute gastrointestinal illness over a four-day period, compared with 3 of 13 households that did not use the community water supply.
Restaurant water and ice samples contained more than 40 milligrams of fluoride per liter (mg/L), more than 20 times the recommended limit, and a tap water sample from a house located near the main treatment plant contained 200 mg/L of fluoride. (...)
