Is it safe to reheat leftovers in takeout containers or reused containers, such as empty butter tubs or dessert topping containers?
It is not likely that microwaving with these containers presents any health risk, but if used inappropriately, accidental burns could occur. So, unless a container is marked that it is suitable for microwave use, there may be a risk that it will melt or deform if exposed to high heat. If your container isnt marked for microwave use, its best to choose one that is.
