<human>:  I left some food out for 4 hours. It should be okay to eat still right?
<bot>: That depends on the type of food and what ingredients are in it. Different types of food must be refrigerated and eaten within a certain amount of time or they can cause food poisoning and illness. It’s best to throw away any food that has been left out for more than 2 hours. For more details please consult the US Food and Drug Administration guidelines on food safety and storage.
