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.

Local honeys sold in public markets, small shops or by individuals are not controlled by public services. Currently, information about its quality is non-existent. The objective of this work was therefore to assess the quality of local honeys marketed in Korhogo town. Samples were collected from twenty local honey sellers located in markets and certain neighborhoods of Korhogo town. Then, their physicochemical parameters were determined. The results showed the existence of significant difference (p < 0.5) between the honey samples for all the parameters studied. The amber colored samples (86 – 113 mm Pfund) were the most numerous (55%) compared to the light amber colored ones and the dark colored ones. The electrical conductivity of these honeys oscillated between 115.67 and 765.67 µS/cm. The refractive index, degree brix and density ranged from 1.4884 to 1.5014; 79.15 to 84.45% and 1.4085 to 1.4442, respectively. The values of moisture content varied between 14.15 and 19.23 g/100g, those of pH and free acidity ranged from 3.42 to 4.49 and from 10.67 to 28.89 meq.kg-1, respectively and those of total acidity and hydroxymethylfurfural content oscillated respectively from 14.67 to 40.22 meq.kg-1 and from 0.56 to 30.05 mg.kg-1. All these physicochemical parameters varied within the limits proposed by the Codex Alimentarius Commission. This suggests that the honeys marketed in Korhogo town meet the quality criteria required for its consumption. However, for further study, their nutrients should be identified and quantified, and their microbiological quality assessed.

Aims: This study was aimed to increase the sustainability of smallholder cotton cultivation in Côte d’Ivoire, through the implementation of Integrated Soil Fertility Management, combining the use of moderate amounts of mineral fertilizer and fortified organic manure. Study Design: The experiment was set up in a Fisher block design, with four treatments and three replications. Place and Duration of Study: The trials were conducted in four locations across two largest cotton growing areas (Odienne and Minignan) in the northern agro-ecological zone, between March and September 2021. Methodology: The technical options included: 1) mineral fertilizer (25 kg NPK ha-1 + 12.5 kg urea ha-1) + 0 kg manure ha-1 (control), 2) mineral fertilizer + 50 kg manure ha-1, 3) mineral fertilizer + 75 kg manure ha-1 and 4) local practice (200 kg NPK ha-1 + 50 kg urea ha-1 + 0 kg manure ha-1). Results: The results showed an increase in seed cotton yield for the manure treatments compared to the control treatment. Non-significant yield difference was found between the manure treatments and local practice. The average yields obtained in Odienne were 5.73 ± 0.70 t ha-1 for 75 kg manure ha-1 and 5.13 ± 0.96 for 50 kg manure ha-1, versus 2.58 ± 0.76 t ha-1 for the control treatment. In Minignan, the average yields obtained were 6.86 ± 1.76 t ha-1 for 75 kg manure ha-1 and 5.73 ± 0.70 t ha-1 for 50 kg manure ha-1, versus 2.58 ± 0.76 t ha-1 for the control. The Agronomic Efficiency of applied manure varied from 37.00 ± 13.07 to 73.41 ± 16.89 kg cotton kg-1 and from 44.34 ± 15.05   to 1 for the two agro-ecological zones. Conclusion: The Integrated Soil Fertility Management system was proven to be a promising pathway for achieving sustainable intensification of smallholder cotton cultivation systems.
