Fluoride levels in mother's milk.
The level of fluoride in milk samples of a group of Malaysian mothers residing in a fluoridated area (0.7 ppm) was analyzed using a fluoride electrode. All the mothers were residents in the locality for at least a year and they were screened for drugs and fluoride supplements. The concentration of fluoride in the milk samples ranged from 0.024-0.172 ppm. The mean value was 0.077 ppm. There were some variations in the fluoride levels of milk samples collected on two separate occasions from the same mother. The implications of these findings on fully breast-fed infants were discussed.
