Aims: Produced in an artisanal way from the fermentation of the seeds of Parkia biglobosa, “Soumbala”, is a condiment very appreciated in several African countries including Côte d'Ivoire. This study was  conducted to assess the microbiological quality and fungal profile of this condiment sold in the markets of nine communes in Abidjan. Study Design: Food safety. Place and Duration of Study: Soumbala's samples were collected in the markets during the month of October 2019 and analyzed at the Laboratory of Microbiology and Food Biotechnology of the Nangui Abrogoua University, Côte d'Ivoire. Methodology: For this purpose, 27 samples of "Soumbala" were taken from the different markets and analysed. The loads of the different microorganisms (mesophilic aerobic germs, total coliforms, moulds) were determined by counting after culture in agar medium. The microbiological quality has been assessed according to Directive 2005/2073/EC. The physico-chemical composition (pH, titratable acidity, moisture content) of "Soumbala" has been determined according to standard methods. The identification of the mould strains isolated from the different samples was carried out using the identification keys. Results: The results of the various physico-chemical parameters obtained ranged from 13.81 to 20.31%, 5.58 to 6.50 and 3.73 to 9.06 % for moisture content, pH and titratable acidity, respectively. The mesophilic aerobic germ loads of 7.21 to 7.70 log10 cfu/g determined in the analyzed samples are above the acceptability limit (6 log10 cfu/g) applied in this study. The maximum loading of total coliforms was 3.92 log10 cfu/g. All mould loads are below the acceptability limit. The mould strains isolated and identified from the identification keys belong to the genus Aspergillus. Conclusion : A public health risk related to the consumption of "Soumbala" could exist if these moulds produced mycotoxin.

In the context of the valorization and the development of local products in Côte d’Ivoire, this study is based on juices samples prepared from the pulp of wild fruits of Baobab (Adansonia digitata), Tomi (Tamarindus indica) and Néré (Parkia biglobosa). The physiochemical characteristics such as dry matter (desiccation, 105°C), mineral (spectrophotometer), ash, fat, fiber and protein (AOAC), Energy (coefficients), vitamins A & C (HPLC), organic acids & total polyphenols (HPLC), carbohydrate (by difference), pH and titratable acidity (titrimetry, NaOH) of pasteurized juices (75°C, 5 min) were investigated. Data showed that the juices have been characterized by low protein (0.21-0.28 %), fat (0.26-0.65 %) and ash (0.20-0.47 %) content and high level of total carbohydrates (21-30 %) and energy (85.83-124.43 Kcal/100mL). Baobab and Tomi juices were distinguished by their high acidity (103-159 meq.g / Kg) while Baobab and Néré juices were characterized by their average fiber content (4-5.30 %). The juices of Baobab, Tomi and Néré are very rich in some minerals (K and Mg) but calcium (Ca) and iron(Fe) are not bioavailable (Oxales/Ca and Oxalates/Fe ˃ 2). The juice of baobab is rich in vit A (80 mg/100mL) and vit C (189 mg/100mL) than the others juices. Catechin was the most phenolic content (52.29-110.32 mg/100mL) where tartric acid was the most organic acid (4.02-6.82 mg/100mL) in the juices. The knowledge of the nutritional value of these juices could contribute to a better understanding of the essential role of these three wild fruits in terms of food and trade.

This study examined the distribution of Escherichia coli (E. coli) resistant to eleven antibiotics and possible relationships among physico-chemical parameters and these resistances. It was carried out over two years during four climatic seasons in five lakes of the Yamoussoukro lake system in Côte d'Ivoire. The physicochemical parameters of the lakes studied are temperature, pH, dissolved oxygen (DO), dissolved organic carbon (DOC), turbidity, nitrates, orthophosphates and ammoniacal nitrogen. A total of 744 water samples were collected from five (5) lakes belonging to the lake system, over a two-year period, during four dry and four wet seasons. Escherichia coli loadings were evaluated after isolation on specific chromogenic medium COMPASS ECC Agar and the susceptibility to antibiotics by the agar diffusion method. Physico-chemical parameters were evaluated according to international standards. The physico-chemical results showed that the nutrient contents evolved generally from upstream to downstream of the lake system, independently of the sources of pollution of five lakes of system. However, the lake B, in upstream of the lake system, showed levels of nitrate, orthophosphate and ammoniacal nitrogen often similar to the downstream lakes. This demonstrates a source of chemical pollution in this lake, which flows to lakes D and E, which are themselves subject to other pollution. Bacterial loads and bacterial resistance to antibiotics have strictly evolved from upstream to downstream of the system. Most isolates were resistant to ampicillin (16.46%), tetracycline (12.87%), ciprofloxacin (12.86%) and sulfamethoxazole (10.14%). Antibiotic resistance patterns of E. coli isolates were similar in both years studied, but higher during rainy seasons (GRS and SRS). The spearman rank correlations and the principal component analysis (PCA) revealed significant correlations between bacterial resistance to antibiotics in lakes and water physico-chemical parameters. Turbidity and DOC can help to determine the main resistances in the lake D. Orthophosphates can help to understand the resistance of chloramphenicol and the nitrates can help to understand the resistance of ampicillin in the lake B. Resistance in the lakes A, B and C can be influenced by dissolved oxygen. Overall, this study provided baseline information on bacterial resistance in the lakes of Yamoussoukro in Côte d'Ivoire, showing that these lakes could be reservoirs of antibiotic resistance, potentially dangerous to public health.

Background: “Soumbara” as well as other traditional foods of Côte d'Ivoire are produced in a traditional way. These foods may contain pathogenic and spoilage microorganisms. Aims: The aim of our work was to assess the sanitary quality of “Soumbara” sold in five communes of Abidjan (Côte d’Ivoire), in order to valorize it as a flavor enhancer. Material and Methods: A consumption survey as well as the analysis of some physico-chemical (pH, titratable acidity, Brix degree, moisture, and organic acids) and microbiological parameters (enumeration of MAG, Clostridium, Bacillus, Staphylococci, Salmonella, E. coli, and coliforms) were carried out in five (05) municipalities of Abidjan (Abobo, Yopougon, Port Bouet, Adjamé, and Treichville) on 75 samples. Results: The results of the survey showed that most of the respondents were familiar with “Soumbara” and often consumed it. These consumers stated that they did not experience any discomfort after consuming this food. Physicochemical analyses showed that the water content of the samples of “Soumbara” ranged from 16.50% to 19.28% and the pH varied from 6.32 ± 0.01 to 7.91± 0.02. “Soumbara” contained little follow-through which ranged from 0.10 ± 0.001 to 0.27 ± 0.05. “Soumbara” also contained phenolic compounds such as coumarins, hydroquinones, and caffeic acid. Microbiological analyses had revealed the presence of spoilage and pathogenic germs such as Bacillus, Staphylococcus, and E. coli at high loads exceeding the 2019/229/EC standard. Conclusions: However, due to the high load of spoilage and pathogenic microorganisms, this food eaten by sprinkling directly on the dish, without passing through a cooking process could expose the consumer to a risk of food poisoning. Keywords: Food poisoning, “Soumbara”, Pathogenic and Spoilage Microorganisms.
