الملخص EN

Dried or smoked fish are consumed in Sahelian countries.

These products may be contaminated by pathogenic microorganisms are more likely to cause public health problems.

The objective of this study is to evaluate the microbiological and physico-chemical quality of fish sold in N'Djamena (Chad) and Ouagadougou (Burkina Faso).

In total, 30 samples of dried fish including 15 from Ouagadougou and 15 from N’Djamena were collected.

The enumeration of Total Mesophilic Flora Aerobic, coliform, Staphylococcus, spores of thermophilic and mesophilic bacillus, Clostridium, yeasts and molds and Salmonella were conducted using standard microbiological techniques.

The solids content and total ash level were also evaluated.

The solids content was about 89.26 ± 11.64% and 91.96 ± 0.25%; the rate in total ash, 12.71 ± 3.72% ± 7.16 and 10.42% for samples from Ouagadougou and N'Djamena respectively.

It appears from this study that the product is dried to 90 %, which explains the strong presence of spore-forming bacteria such as fungal spores and plant a few Clostridium and those of thermopile and mesophilic bacilli.

Dried fish sold in the markets of Ouagadougou and N'Djamena contains high concentrations of microorganisms beyond the required15 standards.

Consumption of these dried fish could pose health problems for consumers.
