There is an increase of food borne diseases in Ghana and therefore a lot of street food studieshave been conducted in Kumasi, the Ashanti Region of Ghana with less information onmicrobiological safety of hotel foods. A total of forty food samples were aseptically collectedfrom five highly patronised hotels (three star to budget). The hotels were selected by simplerandom sampling. Standard methods were used for the dilution, spreading, incubation,enumeration and identification. Serial dilution of each food was prepared in buffered peptonewater and inoculated onto malt extract agar (MEA). Growth were counted and later identified.The bacterial counts were expressed to log10 cfu/g. Two foods from Hotel 01 (fresh peppersauce and chicken and vegetable sauce) and six foods from Hotel 02 (chicken with noodlesand vegetables, jollof rice, fried rice, potato chips, beef in vegetable sauce and coleslaw) wereabove the WHO acceptable levels (< 3 Log 10 cfu/g). Again, 4 foods from Hotel 03 (boiledplain rice, fish light soup, tossed mixed vegetables and tossed salad), Hotel 04 (vegetable sauce,fried chicken, mixed salad and fried rice) and Hotel 05 (goat light soup, fried chicken, friedrice and mixed vegetable salad) were all above the WHO acceptable levels. Fungi isolatedwere Eurotium herbariorum, Aureobasidium pullulans, Alternaria alternate, Botrytis cineriaand Fusarium oxysporu. It was observed that foods tested were above the acceptable levels andcould be sources of food borne pathogens. The causes could be attributed to poor food hygieneand inadequate processing. It is recommended that hotel inspections should include microbialtest on foods.
