By Bulawayo Correspondent POLICE, in conjunction with the Grain Marketing Board (GMB), have launched a nationwide blitz aimed at confiscating imported mealie-meal from retailers that have defied the ban on the import of the staple. Cheap imported maize-meal, smuggled mostly from Botswana and South Africa, has flooded the local market in a development which has resulted in local millers scaling-down their operations and in some instances laying off workers. This prompted the Grain Millers Association of Zimbabwe (GMAZ) to lodge an appeal with the government, which responded by ordering raids on imported mealie-meal. The exercise duly commenced Friday afternoon in Bulawayo.
