Abstract

Yoghurt is a dairy product generally consumed around the globe due to its energy content and  health advantages.  An investigation on the microbiological quality of sixteen yoghurt samples from eight  different brands, four registered by NAFDAC and four unregistered were randomly obtained The pH and  microbiological parameters were evaluated using standard methods. The pH readings of the yoghurt  samples ranged from 4.00- 5.60. The total viable bacteria and fungi counts of the two groups of yoghurt  ranged from 3.0 x 104 ± 1.00 to 28.0 x 104 ± 12.77 and 4.9 x 104 ± 6.24 to 10.9 x 104 ± 4.36 respectively.  There was a significant difference (p
