How long does cooked seafood last in the fridge?

Cooked seafood can last 2 to 3 days in the fridge. The trick of cooking seafood can help us to extend its life one day, but not much. We recommend that you do not risk leaving the seafood cooked for a long time as it will lose its flavor and properties and, in addition, you will risk having to throw it away (or get sick from consuming it in bad condition).

It is very important that you pay attention to the way you store seafood. Unlike beef that can be in the refrigerator without problems for several days, shellfish have a much shorter shelf life. Remember that consuming old or spoiled shellfish can cause an infection or health problem, so you better save yourself those inconveniences

storing shellfish in accordance with these guidelines.

Fresh shrimp, oysters, lobster, and squid can only be refrigerated for two days (no longer). In the freezer, they have a longer expiration time, since they last between three and six months.

In the case of cooked seafood, if cooked the same day it is consumed, it can be refrigerated for up to three days. If you did not prepare the food, check directly with the manufacturer for the consumption instructions to find out how long the dish can be stored in the refrigerator.

Either way, it is very important that before consuming seafood (cooked or fresh) that has been refrigerated or frozen, you check its general condition. These should never smell sour or ammonia-like.

Although they are not shellfish, fish must also be stored carefully to prevent spoilage. The recommendation is that fish (lean and fatty) can be in the refrigerator for up to two days, and in the freezer for six to eight months.

Remember to periodically check the temperature of your refrigerator, which should be at 4 ° C, and that of the freezer at -18 ° C.

In general, seafood is a product that should be consumed quickly. In other words, after having bought it, they cannot spend more than two days cooking or consuming it. Norway lobster is one of the products that spoil the fastest. In addition, we will easily see him as his head begins to turn black. Another type of shellfish, such as barnacles or sea urchins, can last between 3 and 4 days alive in the fridge.

How to preserve seafood so it doesn’t go bad

Within this time that we have said that seafood can hold, there are different methods to preserve it:

  • A damp cloth

Crustaceans such as crab, crab or spider crab will be better preserved if we cover them in the fridge with a damp cloth to help keep them in this condition and not dry out.

  •  In the cold storage box itself

Many shellfish come in a cold storage box (white and cork). If we have it, it is best to close it and store it as is in the fridge. This will help its preservation. It will not last you more days, but it will preserve the characteristics and nutrients it has better during those days.

  •  Water and ice

As we have mentioned before, Norway lobsters are one of the most difficult products to preserve because of their speed at the time of spoiling, so if we want them to be preserved as best as possible on that day or two days that we have them uncooked, the best will keep them in the fridge in a container with water and ice.

  • Freeze it

If you already have the seafood cooked you can also freeze it. When defrosting it will be ready to consume! Frozen seafood will not lose its nutritional value, so it will continue to be rich in protein, vitamins, minerals, and omega 3 and, in addition, we will prevent the growth of bacteria. So, if you don’t know when you are going to consume it, it is best to opt for this alternative.

How do you choose seafood to make sure it is fresh?

It is normal for them to smell, but if they are fresh, they should not smell like fish. The appearance of fresh fish, crustaceans (shrimps, lobsters, crabs), and shelled mollusks (shells, oysters, etc.) are normally moist and elastic, not sticky or dehydrated, according to Health Day.

The eyes of a fresh fish are clear, round, not dark, dry, or submerged. Avoid consuming it if it has a porous appearance. The gills will be bright red, not dark, and will not be sticky.

The tails of shrimp, lobsters, and crabs must not show color changes. The characteristic of fresh oysters is the cream color and the clear liquid.

It is best to buy fresh seafood if you plan to eat it that day. If this is not possible, keep them in the refrigerator or freezer until you prepare them.
