Ultraweak photons could be emitted from the chemical reaction without any electromagnetic radient. These chemiluminescence could be detected by highly sensible photomultiplier recently. We will introduce the principal of chemiluminescence generation reaction, and the application studies in the determination of food-borne microorganisms in field. The counts of surface contaminated microorganism in mackeral and chicken for cold storage determined by ATP-chemiluminescence method had good correlation with the counts by standard agar plate method. However, there was little correlation between 2 methods in ginseng powder whose microbial counts were lower than 10,000 CFU.
