Flour fortification in Zimbabwe

Since 2017, every bag of flour milled in Zimbabwe must contain nine micronutrients. Here is why it matters and how it works.

The problem: micronutrient deficiency

Zimbabwe faces significant micronutrient deficiencies, particularly in women and children under five. In 2018, 26% of children under five were stunted, down from 34% in 2010 but still above the UNICEF acceptable target of 20%. Deficiencies in iron, folic acid, zinc, and vitamins A and B are linked to anaemia, impaired cognitive development, weakened immunity, and increased risk of neural tube defects in newborns.

The regulatory framework

Under the Food and Food Standards Regulations of 2016 (Statutory Instrument 120 of 2016), the Government of Zimbabwe made it mandatory from June 2017 for all industrially milled wheat flour to be fortified. This is one of the most comprehensive flour fortification mandates in sub-Saharan Africa.

Required micronutrients

Vitamin A
Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin)
Vitamin B6 (pyridoxine)
Vitamin B12 (cyanocobalamin)
Folic acid (Vitamin B9)
Iron
Zinc

How fortification works

A pre-mixed fortificant powder containing all required micronutrients is blended into the flour stream during milling using precision dosing equipment. Quality control testing is conducted multiple times per shift to ensure fortification levels meet regulatory standards. The cost of fortification is borne by the millers and passed on to consumers, though the per-kilogram cost impact is minimal.

Why flour is the right vehicle

Wheat flour reaches millions of Zimbabweans daily through bread (1.5 to 1.8 million loaves per day), biscuits, cakes, and home baking. Unlike supplements that require individual compliance, flour fortification is passive: every slice of bread, every biscuit, every chapati delivers micronutrients without the consumer needing to take any extra action.

Challenges

Many of the fortificant chemicals must be imported, making the programme vulnerable to foreign currency shortages. Some food manufacturers have reported difficulties meeting fortification requirements due to intermittent access to foreign currency. Consumer awareness also remains relatively low: only 11-12% of household heads had heard about fortified foods according to the 2018 National Nutrition Survey.

Programme partners

The programme involves collaboration between the Ministry of Health and Child Care, millers, WHO, WFP, FAO, UNICEF, and the Consumer Council of Zimbabwe. The multi-stakeholder approach helps ensure compliance, monitoring, and ongoing adjustment of fortification standards.
