Traditional concoctions sold in marketplaces are always assumed to be safe and efficient; however, they can be potentially toxic because of poor hygienic practices in plant processing or storage. The present study aimed to assess for the microbial quality of market-sold vegetable drugs in Lomé. Thus, a total of 209 plant remedies were collected in marketplaces and analysed for the presence of total aerobic bacteria, total coliforms, thermotolerant coliforms, Staphylococcus aureus , sulphite reducing bacteria, and yeast and moulds according to the French Association of Normalisation (AFNOR) guidelines. The results revealed that all formulations were contaminated by several microorganisms, excepted alcohol-based mixtures. According to AFNOR limits nonconform drugs were according to total aerobic bacteria (86.96% powders, 81.82% capsules, 66.67% tisanes, and 42.11% decoctions); to total coliforms (9.10% capsules, 8.70% powders and 1.75% decoction); to yeasts and moulds (77.78% ointments, 40% calcined powders, 36.36% capsules, and 23.91% powders). The microbiological analysis revealed that the majority of contaminating bacteria were gram positive catalase positive and oxidase positive bacilli. Quality control studies on market-sold remedies are currently needed to evaluate the microbial risk in consuming these products and they may allow the standardisation of plant processing and storage.
