Canned fish is one of the most popular and convenient foods for people who need to save time in the kitchen. Whether it's tuna, salmon, or anchovies, canned fish can be a great source of protein, healthy fats, and essential vitamins and minerals. It's also an affordable, shelf-stable food that can last for months without refrigeration. But how long does opened canned fish last?
The answer depends on several factors, including how it's stored, the type of fish, and how it was processed. Generally speaking, an opened can of fish can last up to three days in the refrigerator, but it should be consumed within two days for the best flavor and texture. It's important to note that the longer a can of fish sits in the refrigerator, the more its flavor and texture will deteriorate.
In addition to refrigeration, proper storage is key to maximizing the shelf life of canned fish. The can should be tightly sealed after opening and stored in a cool, dry place. It should not be left out on the counter or exposed to sunlight.
Types of Canned Fish
The type of fish can also affect how long it lasts once the can is opened. Canned tuna, salmon, and mackerel tend to last longer than anchovies and sardines. Tuna and salmon can last up to five days in the refrigerator, while anchovies and sardines should be consumed within two days.
The type of processing can also affect the shelf life of canned fish. For example, canned tuna and salmon that have been cooked in oil will last longer than those that have been cooked in water. This is because the oil acts as a preservative and prevents the fish from spoiling.
Serving Opened Canned Fish
When serving opened canned fish, it's important to take certain precautions to ensure it's safe to eat. First, make sure the can is in good condition, with no dents or bulges. Discard any cans that are damaged or leaking.
When preparing the fish, cook it thoroughly to kill any bacteria that may be present. Discard any leftovers, as they will not keep for very long and may cause foodborne illness.
Storing Opened Canned Fish
If you have any leftover canned fish, it's important to store it properly to avoid spoilage. The can should be tightly sealed and stored in the refrigerator for up to three days. If the can is not sealed properly, it may cause the fish to spoil more quickly.
If you need to store the fish for longer than three days, it's best to transfer it to an airtight container and freeze it for up to six months. To thaw the frozen fish, transfer it to the refrigerator and allow it to thaw overnight. Once thawed, the fish should be cooked and consumed within two days.
How to Tell If Opened Canned Fish Has Gone Bad
If the canned fish has been stored properly and has not been in the refrigerator for more than three days, it should be safe to eat. However, there are a few signs that can indicate the fish has gone bad. If the can is bulging or leaking, or if the fish has a slimy or fishy smell, it's best to discard it.
