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

Abstract

Introduction . Iodine is a micronutrient, its deficiency causes various serious anomalies that have consequences for public health. Periodic assessments are needed to measure the availability of iodized salt in the community. Objective . 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 . The results revealed that 7.98% of the salts were devoid of iodine, 54.46% had a iodine content <15 ppm, and 37.79% a iodine content >15 ppm. Compared to national recommendations, 35.29%, 20.78%, and 40.24% of salt were adequately iodized, at wholesalers, retailers and in households, respectively. Conclusion . It appears from this study that a very little dietary salt marketed, and consumed in Kara commune is adequately iodized, in accordance with Togolese regulations
