Aeromicrobial profiles of some selected eateries in Sagamu axis of Ogun State, Nigeria

Background: This study investigated some selected eateries frequently patronized in Sagamu axis of Ogun state, for air-borne microorganisms of clinical importance that can cause food borne illness and respiratory infection.

Methods: Bacteriological media appropriate for selected microbes were exposed for 10 minutes in each designated site of sample collection and incubated at 370C for 24 - 48 hours for bacteria, and at 25±30C on Sabouraud’s dextrose agar medium for 5-7 days for fungi. The colonies obtained were enumerated, antibiogram of the isolates were determined and meteorological values considered.

Results:. Main Gate Eatery (MGE) morning counts range from 185±2cfu/mL and 283±5cfu/mL from the
cooking site and outdoor counts while the evening counts ranges from 242±2 cfu/mL and too numerous to count from the cooking site, outdoor and serving table. Ikene Sharp corner eatery (ISCE) exhibited a higher counts range from 235±3 cfu/mL (outdoor), 298±8 cfu/mL (indoor) and too numerous to count (serving table) in morning while the evening counts ranges from 196±2 cfu/mL, 235±3 cfu/mL,280±6 cfu/mL and too numerous to count from the cooking site, indoor, outdoor and serving table respectively. Isale Oko garage eatery (IOGE) elicited 225±2 cfu/mL outdoor morning counts, 270±2cfu/mL from serving table. Antibacterial and antifungal resistance were detected. The meteorological parameter observed varied remarkably.

Conclusions: The preponderance of antibacterial and antifungal resistance from the isolates capable of
transferring resistance factors could be a threat to therapeutic management of these infections. There is a need for surveillance of the eating places by Public Health Inspectors to enforce standard.
