Voluntary Maize Flour Fortification in Tanzania: Adequacy of Small-Scale Processors' Implementation of the Quality Assurance and Quality Control Programmes

This study systematically evaluated the implementation of fortification practices, including quality assurance and quality control, among small-scale processors to ensure regulatory compliance. A descriptive cross-sectional survey was conducted in Ubungo district (Dar es Salaam) and Morogoro municipality, Tanzania, involving 38 processors. Data collection relied on observational checklists and IBM SPSS ® version 20 for analysis. Descriptive statistics revealed critical insights. Cleanliness and sanitation standards were met in only 36.8% of warehouses and 42.1% of production areas, underscoring hygiene deficiencies. Alarmingly, 26.3% of micronutrient premixes were inappropriately stored near heat-generating milling machines. Written procedures for quality assurance and quality control were virtually absent, with just 2.6% of processors having such documentation. A mere 13.2% of processors conducted quality checks on fortified maize flour to confirm micronutrient presence. This study identified pervasive shortcomings in quality control and assurance practices among small-scale processors. Hindrances included inadequate training in fortification standards, limited processing capacity, and constrained access to quality control facilities. Strengthening these practices is imperative to ensure the consistent delivery of safe, high-quality fortified maize flour, essential for the nutritional well-being of target populations. This action holds significant public health and food safety implications.
