The handling of currency notes is an everyday activity that exposes them to various sources of microbial contamination. This study was carried out to evaluate the bacteriological quality of Nigerian currency notes collected from different sources banks, park, and petrol stations. A total of samples of different denominations (₦1000, ₦500, ₦200, and ₦100) were randomly collected from banks, park and petrol station and analyzed using standard microbiological procedures. The currency notes were swabbed, and the isolates were cultured on nutrient agar, MacConkey agar, and mannitol salt agar plates. The bacterial isolates were identified based on their phenotypical characteristics. the isolates were evaluated for their virulence factors and antibiotic susceptibility profile. The results revealed a high level of bacterial contamination on most of the notes examined, with isolates including loads compared to those from banks, possibly due to frequent handling and poor hygiene practices. The presence Staphylococcus aureus, Klebsiella pneumoniae. Notes obtained from petrol stations and park showed higher microbial of potential pathogens on currency notes indicates their role as fomites in the transmission of infectious diseases. This study emphasizes the need for improved public hygiene awareness, regular replacement of old and damaged notes, and the promotion of cashless transactions to reduce the risk of disease spread.
