The three methods of pasteurization authorized at present by law were compared with regard to effectiveness by investigating samples of fluid milk collected from plants and retail stores.<BR>Of the three methods of pasteurization, the ultra-high temperature method (at135°C for 2 seconds) gave the best results both in living bacterial and coli-group bacterial counts<BR>Although samples collected from plants gave favorable results in inspection, those collected from retail stores were inferior to those from plants in sanitary quality. These findings suggest that contamination occurred to fluid milk during transportation or display in retail stores.<BR>It should be noted that samples collected from retail stores gave positive tests for coli-group organisms, while those collected from plants were free from them. Accordingly, great care must be taken in handling fluid milk during transportation and in retail stores.
