Monitoring and impact evaluation of iodized salt intervention in Cameroon.

This study was carried out to monitor current iodization and its impact on iodine excess. The results show medians values increasing gradually from 62 ug/L to 283 μg/L then dropping to 169 μg/L for acceptable significance to above toxicity significant values of 300 μg/L as from 2006, exaggerated in 2018 at 1145 μg/L. Salt iodine contents, compared to the 20 - 40 ppm range recommended by WHO, show coarse grain as lowest with average 26.
