Sugar suppliers have begun complying with mandatory food fortification through addition of vitamin A into their product.

The sugar fortification exercise which is in line with a government directive has come at an additional cost of US$10 per metric tonne for producers or 1 cent per kilogramme.

A survey by the ZBC News showed that retailers taking stock of new supplies were receiving the fortified sugar with local retailer Mr Given Nyaumba highlighting manufacturers had communicated the changes to them.

Grain millers and oil expressers who have challenged the move are yet to comply with fortification of maize meal, wheat and cooking oil.

Mandatory food fortification was introduced from the 1st of this month following studies which showed a substantial part of the local population was vulnerable to nutrient deficiencies.
