There is always a new food trend or cooking technique your restaurant may want to try. But whether you’re incorporating sous-vide cooking techniques or simply adding seasonal produce to drinks, you want to ensure your food safety standards keep up with your menu developments. At the recent Nation’s Restaurant News Food Safety Symposium, microbiologist Brian Nummer reminded the audience of the acronym FAT TOM, which lists the top factors that contribute to bacteria growth: food, acidity, time, temperature, oxygen and moisture. He said when restaurants incorporate new trends into their cooking, it can be easy to neglect safety. But that is less likely to happen if chefs are trained in the science of cooking as well as the art. When that happens, Nummer said, chefs more naturally tweak dishes to ensure safety (say, adding extra lemon to a dish so it reaches a pH 4, which kills bacteria).
