Abstract: `Adoyo` a local anti-malaria herbal drink was examined for the presence and types of microorganisms. Though, an acidic drink, it was observed to harbour bacteria of the genera Lactobacillus, Streptococcus, Acetobacter, Leuconostoc, Bacillus, Proteus, Escherichia and Staphylococcus; Yeasts, of the general Saccharomyces, and Candida while the molds were Geotrichum sp.` Aspergillus sp.` Fusarium sp.` Penicillium sp.` Botrytis sp.` and Alternaria sp. However, these organisms are typical of food spoilage agents, but the presence of Escherichia coli also indicates the occurrence of faecal contamination.
