Abstract :

Microbial transmission, on the surface of any currency note, can either be through direct (hand-to-hand contact) or indirect (food or other inanimate objects) means. To ascertain the degree of bacterial load enumerated during the handling of money and food items, particularly on currency note by denominations, should be of public health importance. Despite the available literature regarding microbial contamination of Nigerian currency notes, there is still paucity of information about how microbial contamination/load differ across the denominations specific to different food vendors. In this context, therefore, the current study investigated bacterial contamination of Nigerian currency notes via a comparative study of different denominations (â¦1,000, â¦500, â¦200, â¦100, â¦50, â¦20, and 10, and â¦5) recovered from local food vendors. Specifically, the different food handlers/vendors included fruit, meat, vegetable, fish, and grain/cereal sellers. All emergent data from 8 x 5 factorial design of experiment were of duplicate measurements. To consider the currency denominations and food vendor type, a one-factor-at-a-time analysis of variance (ANOVA) was conducted. Results showed that about 81.7% of currency notes were contaminated with either Escherichia coli, Klebsiella spp. or Staphylococcus spp. in varying degrees. The higher denominations of â¦500, â¦200, and â¦100 note, with the exception of â¦1,000 note, recorded increased degree of contamination over the lower denominations of â¦50, â¦20, â¦10, and â¦5 note. Based on the total viable count (TVC), the â¦100 currency note appeared the most contaminated (1.32 x 10.sup.5 cfu/ml) whereas â¦5 note appeared the least contaminated (1.46 x 10.sup.4 cfu/ml). The frequency of isolated bacteria on currency notes from vegetable, meat, and fish sellers were significantly higher (p
