If it is exposed to temperatures as high as 90 degrees F, cooked shrimp will only last for an hour or so. After such time, you will have to throw away the cooked shrimp unless you want to risk yourself to food poisoning. There are, however, several ways to increase the storage life of cooked shrimp.
