Objective:

To evaluate the microbiological quality of bread marketed in Ouagadougou and identify critical contamination points throughout the production chain.

Approach:

• Study Area and Sample Collection: The study was conducted at the Laboratory of Microbiology in Ouagadougou, with samples collected from seven locations between March and September 2022.
• Study Design: Two approaches were used: a product-oriented component assessing bread microbiological quality at retail points and a process-oriented component examining hygiene and contamination points during production.
• Bread Sampling: 30 bread samples were collected, with 80% from bakeries and 20% from street vendors, ensuring aseptic conditions and refrigerated transport.
• Microbiological Analyses: Samples were prepared and analyzed according to ISO standards, focusing on principal indicators of bread hygiene and safety.

Key Findings:

• Bread is a significant dietary component in Burkina Faso, with potential risks of microbial contamination during production and handling.
• Low levels of pathogenic microorganisms, including Salmonella spp. and Escherichia coli, were identified in bread samples, with specific counts not detailed.
• Poor adherence to Good Manufacturing Practices by bakery operators increases contamination risks.

Interpretation:

The study highlights the need for improved hygiene practices in the bread production and distribution process to mitigate consumer risks.

Limitations:

• The study focused on a limited number of locations and may not represent all bread production practices in Burkina Faso.
• Only a specific industrial bakery was examined, which may not reflect the practices of smaller bakeries.

Conclusion:

The study provides insights into the microbiological quality of bread in Ouagadougou and highlights critical contamination points in the production process.
