Street food vending plays a crucial role in urban life across West Africa, offering affordable meals and economic opportunities. However, food safety concerns, particularly microbial contamination, pose significant public health risks.

This research focuses on improving the hygiene of street-vended food in Benin, West Africa. Street food is an essential part of the region’s culture and economy, providing livelihoods for many. However, foodborne diseases and poor hygiene practices remain major public health challenges.

Through the RGHI project, I am identifying key hygiene gaps, assessing microbial and environmental risks, and collaborating with street vendors and stakeholders to develop targeted interventions. The objective is to promote safer food handling practices, reduce contamination risks, and strengthen consumer trust in street food safety.

A probabilistic model is being developed to evaluate health risks associated with selected street foods contaminated by pathogenic bacteria, including pathogenic E. coli, Salmonella, Staphylococcus aureus, and Bacillus cereus. This model provides critical insights into contamination risks and contributing factors.

Laboratory experiments are being conducted to visually demonstrate the presence of harmful microorganisms to street vendors, emphasizing the impact of hygiene practices on contamination levels. This hands-on approach encourages behavioral change among vendors.

Key research outcomes include:

• A deeper understanding of street food handling and consumption patterns
• Documentation of the prevalence and levels of pathogenic bacteria in street food
• A probabilistic model assessing health risks linked to street food contamination
• Enhanced hygiene practices among street vendors in Benin
• Training programs equipping vendors with food safety and hygiene knowledge

The project follows a co-creation approach, engaging diverse stakeholders to ensure long-term success and sustainability. By implementing these interventions, this research contributes to lasting improvements in food safety in Benin.
