How long your shrimp will last fresh in the fridge will depend on a number factors, including the sell-by date and whether you’ve stored it in olive oil and lemon juice, which can add some extra time to your expiration date. Typically, though, fresh shrimp and shellfish should be consumed within a few days of purchase and should be kept no longer than a week before being tossed.

Fresh shrimp should have a very mild smell, so if you purchase strong, fishy-smelling shrimp at the store, don’t risk eating something that may have been mishandled or expired before it got to your house.

Poultry

Poultry products -- perhaps most commonly chicken -- are incredibly risky foods to eat past their expiration dates. Even fresh chicken puts you at a risk for developing infections and food poisoning, most commonly from salmonella bacteria, if not handled properly, and can be a serious risk for cross-contamination in a kitchen. Once the chicken is past its expiration date, you’re exposing yourself and your family to these foodborne illnesses even if you cook your chicken all the way through and handle it carefully and according to all instructions.

If you purchase fresh chicken at the store, it can be safely stored in the refrigerator for about two days, even if the sell-by date passes. Chicken that has been frozen can be stored indefinitely if kept at a constant temperature around zero. If thawed in the refrigerator, chicken can be stored in the fridge for an additional two days before being considered dumpster-worthy.
