:-A face mask is a protective device that covers the user’s nose and mouth. It may be used once or multiple times. If for multiple use, it may be laundered or cleaned depending on its texture. The bacterial profile of Covid-19 compliant N-95 face masks were examined during this study. A pack of the N95 Face Mask was bought and given to twenty nine (29) informed and consenting young adult volunteers to use for different number of days. When retrieved, it was immersed in warm water for five (5) minutes. A 10-fold serial dilution was carried out using the Miles and Misra’s method on Nutrient agar Petri dishes and incubated for 24 hours at 350C using the pour plate method. Bacteria colonies were counted and subsequently identified using standard procedures. The result obtained showed that the average colony forming unit per mask (cfu/mask) ranged from 2.5x107 - 1.2x1010. Bacteria isolated from this study were Bacillus polymyxa, Proteus vulgaris, Bacillus subtilis, Klebsiella pneumonia, Staphylococcus aureus, Citrobacter freundii, Bacillus megaterium, Moraxella catarrhalis, Staphylococcus epidermidis. Although some of these organisms may not be out rightly pathogenic, their presence indicates the need for proper handling and hygienic use of all face mask. Single and multiple users of face mask are advised to maintain adequate hygienic condition that will guarantee good keeping quality and healthy use in-order to reduce the microorganisms load as well as improve the quality of air taken in.
