This document outlines a proposed qualitative research study on food adulteration by street food vendors in Chittagong City, Bangladesh. The study aims to examine the current status of food adulteration, limitations of laws in regulating food vendors, health impacts on children, and strategies for prevention. Literature suggests food adulteration is a significant problem in developing nations and that 40-54% of foods tested in Bangladesh were adulterated. The proposed methodology includes using qualitative data from surveys, interviews, and focus groups with vendors and parents. Expected results are identification of locations with adulterated foods, diseases caused by contaminated foods, regulatory loopholes exploited by vendors, and recommendations for new prevention strategies.
