“There is an iron rule: in no case can anything be reused, all leftover food from plates is completely thrown into the garbage,” he said in an interview with RIA Novosti, but noted that this does not apply to food, which can be used several times for some time.

According to him, among such products are pasteurized olives, cheese, butter, honey, jam and so on.
