University of Alberta researchers are concerned after finding E. coli bacteria survived recommended temperatures for cooking meat. Salt also makes E. coli bacteria heat resistant, though McMullen and the other researchers don’t know why. Something’s wrong.’ ”Most E. coli strains heated to 60 C are typically killed in less than a minute, McMullen said. The heat-resistant bacteria survived at 71 C, the temperature long recommended by Health Canada to cook beef. The heat-resistant strains survived at that temperature for more than 70 minutes.
