10 g of each sample was suspended in appropriate medium. The total volume was adjusted to 100 ml by adding soybean-casein digest medium for detection of bacteria and sabouraud dextrose broth for detection of molds and yeasts. Aerobic bacterial colony counts were made by the pour plate technique on soybean casein digest agar. Plates were incubated in duplicate at 37°C for 48 – 72 h. After incubation, the number of colonies was recorded for each plate. Arithmetic mean counts were derived from each item having from 30 to 300 colonies per plate.
