ABSTRACT
The study is aimed at evaluating the microbiological quality control of soymilk beverage sold in I.M.T campus 3 Enugu. The soymilk samples were collected randomly from all the soymilk hawkers in campus 3 I.M.T Enugu. 30 soymilk samples were collected and used for the study. All the sample were freshly prepared, serial dilution of the soymilk samples was carried out. The sample were cultured using the streaking method on nutrient and Macconkey agar media Gram staining and microscopic examination was carried out to identify the organism. Biochemical test were finally carried out to confirm the implicated organism. The bacteria implicated in this study were staphylococcus sp and escherichia coli.
