Biomedical analyses laboratories are particular sector of healthcare systems whereby professionals are especially exposed to high infectious risks. The current analytical study aimed to assess the level of hygiene in the laboratory of biomedical analyses of the area hospital of Mènontin in Benin. A scorecard of good laboratory practice has been developed on the basis of laboratory inspection checklist of the World Health Organization. The laboratory has been split into two sub-sections A1 and A2. Ninety-one swabs from hand, cell phones, work surfaces and door knobs were collected from the two main sections and submitted to bacteriological analyses.The observations revealed that hygiene rules are less respected in the laboratory A1 than A2. Similarly, the framework, the waste management practices and technical arrangements are in disagreement there with biosecurity rules. After culturing, 55 samples showed growth of colonies. Some of these samples were polymicrobial. Coagulase negative Staphylococcus were the most isolated bacteria from hands. Cell phones were essentially contaminated by Pseudomonas aeruginosa, Enterobacter cloaceae, Klebsiella pneumoniae and Acinetobacter spp. Escherichia coli was the most predominant specie isolated from the work surfaces and from all door knob. Almost all these isolates were multidrug resistant.With respect to the strategic place of laboratories in the sanitary system of a hospital, urgent and appropriate measures must be taken to mitigate the risk of laboratory acquired infections among professionals.
