A University of Calgary, Canada, study found “alarmingly high levels of bacteria in water bottles that were reused without being cleaned,” reports Better Homes & Gardens magazine. In the study more than 13 percent of bottles used by elementary school students exceeded safe bacteria levels.
The bacteria included fecal varieties—likely because of the students’ poor hand-washing habits. One researcher suggests that water bottles should be washed out regularly with hot water and soap and should be allowed to dry completely before each refill.
This is a food for thought to all parents.
