In Côte dIvoire, Cassava roots are mainly processed into attiéké, a kind of fermented cassava semolina, dried and steamed. This food, widely consumed, is produced by women according to a traditional technology requiring several hard operations. When the dough is not immediately processed into attiéké, it rots. Therefore, an improved process involving washing and storage of the fermented dough in a closed bucket was tested. This process lead to a stabilized dough which could be preserved for at least four weeks. The cyanide content in this dough represented 25% of the traditional ones (39.50 ± 0.8 mg/kg). Both dough were safe of Enterobacteria. They mainly contained lactic acid bacteria (1 to 1.7×108 cfu/g) which grew during the stabilized dough storage. Attiéké from this dough was similar to the traditional attiéké. As stabilizing the fermented dough, the new process should encourage the growth of attiéké production efficiency, the producer incomes and cassava production increase.
Production of attieke in Cote d'Ivoire requires the use of inputs such as the cassava traditional inocula, palm oil and water. These three inputs are involved in the entire production process. Contamination of these ingredients will result in a finished product of uncertain health quality. For the implementation of HACCP (Hazard Analysis Critical control Point) in the production of attieke in Cote d'Ivoire, it is therefore necessary to identify the microbiological hazards in these ingredients (cassava traditional inocula, palm oil and the water used for the production of attieke). The imputs contained pathogenic microorganisms. Bacillus subtilis, Bacillus cereus, Staphylococcus aureus, Citrobacter freundi, Enterobacter amnigenus, Citrobacter youngae, Enterobacter aerogenes, Klebsiella pneumoniae, Enterobacter agglomerans and Klebsiella oxytoca were the bacteria isolated, and Rhizopus spp., Mucor spp., Thamnidium spp., Fusarium spp., Moniliella spp. were the fungi isolated.The occurrence of some bacteria and fungi illustrate that cassava traditional inocula,
