The product is widely consumed in Burkina Faso. The objective of the present study was to investigate the biochemical and the microbiological characteristics of attiéké from Burkina Faso. The samples (36) were collected from six (6) producers. Cassava dough which is used for attiéké production contains from 70.67% ± 0.25% to 86.02% ± 0.2% as starch. The undesirable organic elements rate is about 1.28% ± 0.14% to 26.46% ± 0.53%. The inorganic impurities rate is about 0 to 7 ± 0.1 mg/100g. Cassava dough acidity varies from 1.8 ± 0.2 to 12.4 ± 0.1;and its pH from 3.48 ± 0.01 to 4.20 ± 0.01. Lactic bacteria are the main microorganisms involved in cassava dough fermentation (5.17 to 9.30 log cfu/g). Yeasts and molds number is low (<6.53 log cfu/g). Attiéké moister is about 50.6% ± 0.00% to 55.12% ± 0.7% and its protein contents from 0.77 to 1.74 ± 0.13 g/100g. The content in lipid of attiéké shows an important variation and is about 0.15 to 3.28 ± 0.32 g/100g. Carbohydrates content varies from 36.6 ± 0.04 to 47.01 ± 0.1 g/100g and its ashes content is from 140 to 780 ± 20 mg/100g. Attiéké acidity and pH are less weak than cassava dough. They vary respectively from 0.92% ± 0.05% to 4.08% ± 0.57% and from 3.7 to 4.4 ± 0.01. As a main energizer food, attiéké energizing value is from 161.95 to 215.26 Kcal/100g. All the attiéké analyzed was exempt of aflatoxin (B1, B2, G1, G2) and ochratoxin A. The local attiéké has higher acidity, fermented bacteria load, protein and minerals salt than the imported one. The process mastery is the mainly factor that determines nutritional and sanitary quality of attiéké.展开更多

However, the hygienic quality of these imports is not guaranteed for the consumer. The aim of this study was to estimate the frequency of unhygienically unsatisfactory imported poultry and to determine the antibiotic resistance profile of Salmonella spp. strains. A total of 285 samples of imported poultry, including 55 chicken thighs, 10 chicken backbones, 25 chicken wings, 5 whole chickens, 30 sausages, 35 chicken forequarters, 95 chicken drumsticks and 30 guinea fowl wings, were analyzed using standard AFNOR routine methods. The following germs were tested: Total Aerobic Mesophilic Flora (TAMF), Anaerobic-Sulfite-Reducing (ASR), Escherichia coli, Staphylococcus aureus and Salmonella spp. Antibiotic susceptibility testing was carried out on Salmonella spp. strains isolated using the agar disk diffusion method (CA-SFM). Results showed 100% compliance for TAMF, coagulase-positive Staphylococci and Escherichia coli. On the other hand, 3.84% and 2.46% non-compliance were recorded for ASR and Salmonella respectively. Non-compliance with hygiene rules is generally thought to be the cause of meat contamination. Seven 7 strains of Salmonella were isolated, 5 of which were of the OMA serogroup, and the other two of the OMB and HMB groups. Antibiotic susceptibility tests revealed resistance to certain beta-lactam antibiotics and quinolones, in particular: cefalexin (28.57%), cefoxitin (14.28%), cefuroxime (28.57%), ceftazidime (28.57%), ceftriaxone (28.57%) and nalidixic acid (28.57%). This result may be explained by the uncontrolled use of B-lactam and quinolone antibiotics in poultry farming. As Salmonella spp. is a pathogenic enteric bacterium that causes food-borne illness in humans, resistance to third-generation cephalosporins remains a major public health problem.展开更多
