Insulation test of Listeria in raw milk in Benin

Abstract

Milk is a very rich food and favors the development of microorganisms. It is most often implicated in cases of foodborne illness. Therefore, it should be subject to control of all microorganisms of food poisoning in order to preserve the health of consumers. But Listeria, which increasingly is indexed, is not frequently sought in food in Benin. The present work was done to isolate Listeria and identify problems related to that. Thirty (30) samples of raw cow's milk were analyzed at the National Laboratory of the Ministry of Health (Benin). Listeria was isolated in 9 samples, a percentage of 30%. No major difficulties, apart from the problem with the supply of specific media culture of the bacteria were noted. It is possible to isolate Listeria in Benin so this study showed that the research of this organism should be now included in diagnostics in food technology in Benin.
