The Grain Millers Association of Zimbabwe (GMAZ) has deployed price monitoring teams across the country to ensure that retailers adhere to the stipulated prices.
Products classified as grains include mealie meal, rice and flour.
The development follows an agreement between the Confederation of Zimbabwe Retailers (CZR) and GMAZ in March this year to devise a framework for setting prices of grain products.
Those retailers found overcharging by the price monitoring teams risk withdrawal of grain product supplies.
