This study was carried out to better appreciate the sanitary situation of chicken grills sold near the streets of Korhogo town. First, a survey was conducted in sixty sale places of grill to describe the methods of preparation and storage of chicken grills. Then, the environment, equipment, raw material, method and workforce were observed in order to assess the hygiene of the preparation of these foods. After that, the microbiological quality of chicken grills was evaluated by looking for total aerobic mesophilic flora, faecal coliforms, S. aureus and Salmonella spp. Finally, the benzo[a]pyrene content in chicken grills was estimated through a cooking test. The survey revealed that the majority of sellers of chicken grills cooked the meat over an ember fire and stored the unsold grills cold in refrigerator or cooler. In most of the places of sale, the sellers did not comply with the principle of separating “clean” areas from “dirty” areas. Microbiological analysis showed that the overall quality of the chicken grills was unsatisfactory in most cases. The main microorganism responsible for the unsatisfactory quality of chicken grills was the total aerobic mesophilic flora (54.18 %). Moreover, the cooking test indicated that chicken meats cooked over an ember fire had a benzo[a]pyrene content above the maximum recommended limit (2 µg/kg). These results suggest that the chicken grills sold along the streets of Korhogo town are likely to represent a risk to consumer health. Therefore, sellers of chicken grills should be raised awareness and trained on good hygiene practices.
Market gardening is an activity commonly practiced in the city of Korhogo. This study made it possible to take stock of this activity with a view to improving it for the benefit of consumers. A survey was therefore conducted among 100 market gardeners in the Kassirimé, Natio-Kobadara, Koko and Téguérré neighborhoods and 100 vendors at the Sinistré and Belle-Ville markets and at the large market. The results showed that the majority of market gardeners and sellers are women who have not been educated, with more than 10 years of experience. The analysis of production sites through the requirements of the GLOBALGAP standard showed non-compliance rates above 90%. The study on market gardening sites and markets using the ISHIKAWA causality diagram made it possible to identify the risk factors and to propose measures for controlling the dangers. The survey showed that vendors use aeration, ventilation, immersion, drying and sprinkling for the preservation of vegetables. Moreover, market gardeners, like sellers, encounter problems in the practice of this activity. These problems are linked to the lack of supervision, access to agricultural credit and pest’s attacks.
