How many times can you use oil for deep frying?

How many times can you use oil for deep frying? There is no set number, but there are some guidelines. The first thing I would recommend is to never reuse cooking oil that has been used for deep frying more than 3-4 times as it will have a long term negative impact on the flavor of your food and may start to make people sick from the buildup of toxic substances in the fat.
