Abstract
Yoghurt is widely consumed for its nutritional value and associated health benefits. This study
aimed to evaluate the bacteriological quality of yoghurt sold in Kabuga, Kano State, Nigeria.
Five different commercially prepared yoghurt brands were randomly purchased from various
outlets and analyzed using standard microbiological procedures. Four out of the five samples
showed significant bacterial growth, ranging from 4.8 × 10⁶ to 9.5 × 10⁶ CFU/mL.Gram staining
and Biochemical characterization of the isolates revealed the presence of Micrococcus roseus,
Staphylococcus aureus, Streptococcus spp., and Micrococcus luteus. The presence of these
organisms, some of which are potential pathogens, indicates poor hygienic practices during
production and handling. The findings underscore the need for strict regulatory oversight and
improved sanitary measures in the preparation, packaging, and distribution of yoghurt to
safeguard public health.
