Evaluation of the iodine content of food salts in the commune of Kara in Togo

Introduction . Iodine is a micronutrient, its deficiency causes various serious anomalies that have consequences for public health.

To essay by iodometric titration the iodine contained in the food salt, by wholesalers, and semi-wholesalers, and consumed in the households of Kara commune in Togo. Material and Methods . A collection of food salt samples was conducted from 4 wholesalers, 64 retailers, and 330 households in Kara commune, Togo, from August 15 th to 30 th , 2017. The iodine content of the 431 salt samples collected was estimated by iodometric titration. Results .

Compared to national recommendations, 35.29%, 20.78%, and 40.24% of salt were adequately iodized, at wholesalers, retailers and in households, respectively. Conclusion .
