New Study Concludes Some E. Coli Pathogens Can Survive High Cooking Temperatures
A new study released this month concluded that some strains of E. coli bacteria, a deadly pathogen found in a number of food products like ground beef, can survive the cooking process. The study prepared foods to certain temperatures and discovered that some pathogens were still alive past 160 degrees F, the recommended temperature for cooking meat products in order to kill the bacteria. There are many different strains of the pathogen E. coli. Not all of them pose a serious health risk, but some like O157 can cause kidney failure and have even led to death in some instances.
The team of microbiologists who conducted the study hailed from China’s Huazhong Agricultural University, as well as an institution in Alberta, Canada. Information suggesting that some pathogens may survive high cooking temperatures has been available for nearly a decade, but it was not until recently that the subject was explored specifically and in greater depth.
The next phase of research for the team will involve exploring how commonly pathogens survive the cooking process and which strains of E. coli may be particularly impervious to heat. They will also look at other pathogens to see whether this issue is happening in other contexts. Another avenue of research will involve identifying other food ingredients that may help kill the pathogen.
