Foreword  
 
This Draft Ta nzania Standard is being developed by the Industrial and Laboratory Chemicals Technical 
Committee under supervision of the Chemical Division Standards Committee and it is in accordance with 
the procedures of the Bureau.  
 
A need has been felt to prepare a g uideline for hygienic practice for  production , packaging, 
transportation, storage and sale of Iodated Salt  because of importance of iodine as a micronutrient 
needed for human health. Iodine deficiency disorders include mental retardation, brain damage, gr owth 
impairment to children and goiter, which can be prevented by use of iodized salt and effective monitoring 
of iodine nutrition.  
The guide is meant to directly contribute to the overall effort to strengthen food fortification in our country. 
It is our h ope that the use of this guide will help strengthen food control activities in our country in order to 
deliver safe and quality fortified foods to the Tanzania population.  
 
This Draft Tanzania Standard has been prepared with assistance drawn from:  
FDA/FID/ CP-FOR/2013/02  Code of practice for the manufacture, packaging, transportation, 
storage and sale of iodated salt published by Ghana Food and Drugs Board.
