Introduction: School canteens must comply with hygiene and food safety rules, especially when it comes to children. It is impor tant to take into consideration what is on their plates and how they are made. Snacks offered in schools contribute to a balanced diet, allowing students to stay focused and improve their academic performance. Aim/Objective: This study aims to improve the hygienic quality of ready meals sold in schools in Commune II of the city of Niamey. Methodology: The data was collected from December 2023 to January 2024 and involved 60 vendors in five schools, including two private primary schools, one public primary school, and two secondary schools (one public and one private). Result: The results showed that 96.7% of vendors are women and are mostly out of school (38.3%). Several food safety and hygiene issues were observed, including selling food near gutters (3.3%), exposure to sunlight and open air of food (61.7%), use of street clothes (93.3%), neglected hand hygiene (68.3%), and nail care (71.7%). For the FAMT, microbiological analysis showed that 40% of the samples were compliant, while 60% were non-compliant. The results showed that all samples were non compliant for total and fecal coliforms. Concerning Escherichia coli, 60% of the samples were also non-compliant. On the other hand, for yeasts and moulds, 100% of the samples were found to be compliant and 20% of the samples were non-compliant for Salmonella. Conclusion: A comprehensive and systematic assessment of the safety and quality of food and food prepared by school ven dors would therefore be crucial, both to ensure the health of school children and to ensure the socio-economic importance of school food sales.
