With the many articles on food safety, I wonder is it okay to leave food sitting out after everyone has eaten. We usually leave things out for hours so that everyone can snack and graze when they want more food. We have never put things away after two hours, but now with all the articles on quickly putting things away after two hours, I wonder if traditional family practices of leaving food out pose any significant health threats? And is leaving food out during the holidays any different than leaving food on the stove for when your kids get home on any other day etc.?
