ABSTRACT
The microbial quality of garri sold in Swali market in Bayelsa State, Nigeria was studied. A total of eight (8)
samples (4 white and 4 yellow) were purchased from different spots in and around the market. The samples were
analyzed for total aerobic plate count and total coliform count on nutrient and MacConkey agar respectively
using spread plate method. The moisture content was also analyzed. The moisture content ranged from 10.09% to
15.4% for yellow garri while white garri had a moisture range of 10.45% to 14.95%. The total aerobic plate count
for the yellow garri was between 1.5×104 and 2.8×104, total coliform count ranged from 5.2×103 to 1.14×104,
while the white garri had a range of between 3.6×103 and 1.2×104, for total aerobic plate count, and from no
growth (NG), to 9.5×103 for total coliform count. From the result of the study, the moisture content of some of the
samples exceeded the safety limits; total aerobic plate count was within the tolerable range, while the presence of
coliform calls for concern. Proper handling, packaging and storage under hygienic conditions are recommended.
Also proper drying of garri to lower its moisture content should be encouraged.
Keywords: Total aerobic plate count, total coliform count, moisture content.
