The TPC, S. aureus, C. perfringens, Salmonella and V. parahaemolyticus were not detected in cooked ingredients. The number of TPC in Khao kluk ka pi held at ambient temperature for 0, 2, 4 and 6 hours were founed an increase from 1.2×106 cfu/g to 7.6×106, 1.8×107 and 3.4×108 cfu/g respectively that was as a result of the uncooked ingredients and mixing process.
