Study Protocol: A Mixed-Methods Investigation of the Impact of Health and Safety Practices on the Business Performance Among Street Food Vendors in Johannesburg

Abstract

The informal street food sector serves as a vital component of urban economies in South Africa, providing affordable nutrition and employment. However, this industry struggles to comply with required health and safety practices and standards. This study protocol outlines a mixed-methods investigation into hygiene practices, regulatory compliance, and the intersection with business sustainability among informal food vendors in Johannesburg’s inner city. This study aims to investigate how vendors’ perceptions of health risks and benefits influence compliance behaviours and, in turn, how these behaviours impact operational efficiency, financial stability, and customer trust. Grounded in the Health Belief Model (HBM) and the Balanced Scorecard (BSC) framework, the research seeks to explore both behavioural drivers and performance outcomes associated with hygiene adherence. The study will employ structured stall observations, semi-structured vendor interviews, and customer surveys across high-density vending zones. Quantitative data will be analysed using descriptive and inferential statistics, while qualitative data will be thematically analysed and triangulated with observed practices. The expected outcome is to identify key barriers and enablers of hygiene compliance and demonstrate how improved food safety practices contribute to business resilience, customer trust, and urban public health. The findings aim to inform inclusive policy and innovative business support strategies that integrate informal vendors into safer and more sustainable food systems.
