Abstract
Sterilized whole milk was inoculated to contain an initial population of ca. 10(6)-10(7) cells of Yersinia enterocolitica or Campylobacter j ejuni/ml. Inoculated milk samples (20 ml) in vials were immersed in wa ter and heated for 1-20 min with a microwave oven (2450 MHz) set at 71 .1-degrees-C. Heating for 8 min completely inactivated Y. enterocoliti ca so negative results were obtained by cold enrichment. Heating for 3 min inactivated all cells of C. jejuni.
