Sometimes it might happen that you visit a relative’s place for dinner and come back with some of the leftovers at the party. There are chances that you forget about it the next day.
But when you do realize it, the time may not be right. So in such cases, if you have even a slight doubt about any food item, just dispose it off. Never taste or smell such foods as it can have food poisoning bacteria that can’t be seen or tasted!
So the right thing to do is wrap this suspected food and throw it down the bin.
