We have conducted several investigations on the amount of microorganisms in sencha. In the present study, we examined the effect of firing stage on the amount of microorganisms in sencha. The amount of microorganisms was measured before and after the firing stage. The results were as follows. No coliform bacilli were detected after firing. The amount of fungus decreased dramatically after firing. The amount of thermoduric bacteria showed little decrease or increase, while the amount of standard plate count bacteria showed a strong negative correlation with the accumulated temperature of three types of tea dryer. Key words: firing, sencha, microorganism
