The aim of this study is to assess microbial quality of rice in Lahore. A total of 20 rice samples purchased from different markets were analyzed to study the density of microorganisms by standard plate count (SPC), fungal count (FC), coliform counts (CC) and prevalence of Bacillus cereus. The Moisture Content was also investigated. Highest moisture content (14.9%) was found in the samples purchased from Samnabad while the lowest moisture content (8.46%) was observed in "Flora Basmati Rice". The microbial load was found to be higher in unbranded rice samples. The Fungal genus isolated from cooked and uncooked rice samples were found to be in the order of Rhizopus spp. (76%), Aspergillus flavus (67%), Mucor spp. (64%), Aspergillus spp. (42%), Penicillium spp. (31%). All the samples showed the presence of B. cereus, the highest count (3.34x10(1) CFU/ml) was observed in unbranded samples taken from Sadar while the lowest count (0.933x10(1) CFU/ml) was recorded in Flora Basmati Rice. E. coli was absent in all samples analyzed.
