We use stainless steel insulated containers from KleanCanteen, pre-heated with boiling water. Food goes from the microwave to the container steaming hot. My kids report the food is still steaming when they open at lunch. Soups have been known to be too hot to eat without cooling down first. |
Mayo is slightly acidic. It's less dangerous than you think. Same goes for any tomato-based sauces. |
How is lukewarm mac n cheese more dangerous than a sandwich with deli meat? Given all the listeria outbreaks, I'd be more leery of a turkey sandwich than a warm lunch. |
well i guess my kids are screwed because we did that their entire education. I should probably let them know that might get sick someday. |
School lunches are hot. Join the missing middle. |
How my kid survived to be 20 eating warm food from her thermos all those years, I have no idea.
Eye roll. |
If you put it in hot in a good container, it will be hot at lunch time. For extra insurance, fill the container with hot water first. From the US Department of Agriculture: "For hot foods, use an insulated container to keep food like soup, chili, and stew hot. Fill the container with boiling water, let stand for a few minutes, empty, and then pour in the piping hot food. Keep the insulated container closed until lunchtime to keep the food hot — 140 F or above." https://www.usda.gov/media/press-releases/2023/07/17/dont-flunk-food-safety-school-year |
What? In the winter I send soup at 7am. Its still hot enough to burn at 1. |
Do you really not know how a thermos works? |
As others have said, my son used to complain the food was too hot. I am surprised at how well thermoses work. |
Or anything thermos brand. |
I've done this quite a bit, including pasta with meat sauce, meatballs in tomato sauce, mac and cheese.
Heat the food until it's steaming or boiling. At the same time, fill the thermos with boiling water, screw the lid on, and let it sit 5+ minutes. Then empty the thermos and immediately pack the food in. Try to get it really full - dead air inside the thermos will let the food cool down faster. With that method, my kids report that when they open the thermos at lunchtime, the food is still steaming. Nobody has ever gotten sick from it. |
USDA says hot food in an insulated container is fine. Thermos advertises that hot food stays hot for 8 hours in the kids' food jar version. If it was dangerous for people to use Thermoses for what they are designed for and advertised to do (i.e., keeping food warm for a few hours) then Thermos would have been sued into oblivion by now. https://www.usda.gov/media/blog/2023/07/24/make-food-safety-honor-roll-school-year https://thermos.com/collections/food-jars/products/12oz-icon-kids-food-jar |
I don't send meat in a thermos - I will send leftover pasta, cheese & bean enchiladas, etc. |
Girl, I've sent a thermos full of soup in the same lunch bag as a small ice pack and a sandwich and my said the sandwich stayed cold and the soup stayed hot. |
