How Long do Raw Prawns Last in the Fridge?

Prawns, which range in size from big to pink to white to microscopic, are a fantastic source of protein. It cooks rapidly and goes well with many different taste combinations, including lemon-garlic, hot honey, and Sriracha. The crustacean must be properly chilled to maximize its benefits. Learn how long raw prawns can be kept in the refrigerator and some storage advice.

What are Prawns?

There are countless varieties of prawns, but the three most popular in the UK are tiger, king, and north Atlantic. They are caught both wild and farmed in both salt and fresh water.

The majority have long, whiskery antennae and a slender, tapering body beneath which the tail is curled. All varieties have ten legs, and a fragile shell covers the body. They are blue-gray or, in the case of the smaller types, quite translucent when uncooked.

When cooked, the sweet, meaty flesh turns white with a pink tint, while the shells turn pink. Cooking must be done quickly. Otherwise, the flesh will become tough. Prawns caught in cold seas are more flavorful than those caught in warm waters, similar to other forms of crustacea. The meaty body of the prawn, which is anatomically incorrect, is known as the tail. The term “shrimps” denotes the microscopic size of the very little shellfish, which are prawns.

How Long do Raw Prawns Last in the Fridge?

In the refrigerator, raw prawns keep for one to two days. If you can’t boil the shrimp within two days, you can freeze the raw shrimp to extend its shelf life. There may be a “Finest-By” or “Use-By” date on some shrimp packaging, representing the packagers’ prediction of when the product will be at its best. Prawns may remain fresh for an additional two days after that date, but you should always check the texture and fragrance.

It is preferable to discard the prawns if it is slimy or offensively smelling ammonia. Be sure to have a dish in mind when you purchase the crustacean because it has a limited shelf life in the fridge before it needs to be prepared (check out these healthy prawns recipes for inspiration).

Prawns can be frozen by spreading them out in a single layer on a baking sheet and freezing them until firm (doing so prevents the prawns from sticking together as they freeze). After that, transfer to a freezer-safe, sealed bag. It’s important to name and date the bag to know when the contents were frozen. Although prawns can be frozen for up to a year, it is best used within three months for the best flavor and texture.

What is the Correct Method of Storing Prawns?

Keep them Chill

Even though it seems clear, this one is crucial. You may preserve your prawns for longer by keeping them cool and in an airtight container, reducing the chance of germs growing there. When you buy your prawns, you might want to carry a small esky or cool bag to store them in the coolest region of your refrigerator.

Grab them Now

Prawns should be bought as soon as possible before dish day. The better, the fresher they are. Prawns can be stored in your refrigerator for up to 3 days, whether cooked or raw. Choose the freezer if you don’t anticipate it’ll be consumed in that period.

Prawns can live for six to eight months if stored below -18 °C.

Keep your Shell On

A prawn’s shell should always be left on until right before preparation. Even though peeling prawns on an empty stomach can be challenging, doing so can help them last longer.

How to Peel Raw Prawns?

  1. Remove the head and throw it away (or retain it for making stock). Grip the legs while turning over, then push the shell to one side.
  2. Pull back the tail’s legs and individual shell shards.
  3. To give the prawn a decorative appearance, leave the tail and end segments on. If not, just cut them off.
  4. While holding the prawn, make a short, thin incision down the back of the tail using a small, sharp knife, careful not to cut all the way through.
  5. Remove the black intestinal tract by opening along the incision. The prawns can now be cooked.

What is the Difference Between Prawns and Shrimp?

The shrimp and the prawn are among the least understood of all crustaceans. Some people believe they are the same thing, while others believe they differ in size or go by different names in other states, regions, or nations. But all of these folks are mistaken! Prawns and shrimp are very different animals. Yes, they are both decapods, which means they have ten legs and external skeletons, but that is the only similarity between them. Prawns and shrimp both fall under the Pleocyemata suborder of the animal kingdom. Let’s investigate what this discrepancy signifies.

Gills: As you might recall from biology class in the ninth grade, gills are designed to have the most surface area possible. Prawns have branching gills, where I assume the “branchiata” portion of their name comes from, while shrimp have plate-like gills made up of flat, layered patterns.

Pincers and claws: The largest pincers and claws on a shrimp are on the front legs, which have two pairs of claws each. Three pairs of legs on prawns have claws, and the second pincers are larger than the front ones.

Let’s say that these decapods have a body structure with four unique parts: the head, the thorax (the region directly behind the head), the abdomen (the “torso”), and the tail. Like shingles on a roof, the head and thorax of prawns overlap with the abdomen. In shrimp, the thorax forms a cummerbund-like overlap with the head and the abdomen.

Habitat: While shrimp can be found in freshwater and saltwater, prawns only exist in freshwater (though most species come from saltwater). Fun fact: Shrimp are smaller the colder the ocean they come from! (I used to find the little shrimp in shrimp salads that reminded me of Scandinavian cuisine to be scary, but I no longer do.)

How to Pick the Top-Notch Prawns?

Raw or cooked, fresh prawns should have a clean, fresh scent that isn’t fishy and should appear wet. Avoid any that appear dry or that have shells with breaks or cracks.

Buy twice as much weight of shell-on prawns as you would need of shell-off prawns.

Raw or cooked prawns can be purchased. Although cooked prawns can be consumed cold as-is, they can be used in the same manner and in different types of meals. They have a blue-gray color when uncooked (sometimes called green prawns).

Big and juicy king or tiger prawns are the ones most frequently served uncooked, either entirely in their shells or without their heads (if the latter, they are called prawn tails). The prawns from the North Atlantic are smaller and are frequently offered whole and sold raw.

Prawns get pink when cooked. Both king and tiger prawns are sold cooked, frequently without their heads or shells (except the very tip of the shell). Additionally, cooked North Atlantic prawns are offered for sale, either whole or decapitated; if headless, the shells are typically removed (aside from the very end of the shell).

Shrimp come in pink and brown variations and are available already cooked. The greatest option is ready-peeled fruit, as it’s a fiddly job.

What are the Different Methods of Consuming Prawns?

Using your Hands to Eat Prawns

Prawns can be eaten with your hands if they are served whole.

Start by pulling firmly on the head and tail to remove them. Remove the shell from the belly, where the legs join the body. To break the shell, place your thumb directly over the legs. Take the legs off. Then remove the shell. Gently bend the prawns against the curve of the shell if you need to break up the shell.

Some people also remove the prawns’ black veins from the rear. The vein is the digestive system, and it can be eaten. It can be messy and nearly surgical to remove it.

Therefore, you can leave the fine black thread and continue eating if it does not bother you.

Use the prawns’ tails to handle them and bring them to your mouth if they are served headless but with their tail. Then throw the tail away.

Use a Fork and Knife to Eat Prawns

You should use a fork and knife to eat prawns on formal occasions or if they are included in an oily or saucy dish.

To hold the prawns, grip the body with the knife and carefully insert the tips of your fork just above the point where the legs meet the body. Using the fork to support the body, carefully cut the head and tail off with your knife. Gently insert the knife’s tip into the shell’s opening where the tail protruded. Gently work your way up with the knife to remove the shell.

Put the shells, tails, heads, and legs in a separate bowl or plate. If there isn’t a spare plate or bowl, arrange them neatly on one side of your plate. Use a fingerbowl, typically provided, to wash your fingertips while adding a few drops of lemon juice to the water.

What is the Nutritional Value of Prawns?

Prawns are a complete protein source, which includes all nine essential amino acids in the optimal balance for optimum bodily function. Prawns contain about 25 grams of protein per 100 grams, which is about the same as a comparable serving of chicken or beef.

Beef contains three times as much as chicken, which is nearly twice as much. There are very few calories in prawns. Only roughly 115 calories are present in the same 100 grams of prawns.

Prawns have higher than usual levels of cholesterol. However, their healthy fat profile prevents them from raising blood cholesterol levels. This is because they have an almost three-fold higher concentration of omega-3 fatty acids than omega-6 fatty acids.

Studies have demonstrated a link between meals strong in omega three and a lower risk of heart attacks and blood pressure. In actuality, prawns’ high cholesterol content is essential for a balanced diet.

Vitamins B-6, B-12, and Niacin, which support the body’s ability to produce energy, develop muscle, and replace red blood cells, are abundant in prawns.

Iron, a mineral necessary for the body to distribute oxygen efficiently, is present in prawns in large proportions. Iron deficiency, which results in extreme exhaustion, is surprisingly common, especially in women, even though it is only found in a few food types.

Selenium, one of the best antioxidants for preserving healthy cells, is abundant in prawns.

They also contain a lot of zinc, which is necessary for a strong immune system.

Due to their high phosphorus, copper, and magnesium content, eating prawns promotes the development of strong bones.

Reference: Factors that influence consumption of fish and omega–3-enriched foods: A survey of Australian families with young children

The most popular types of fish and seafood typically consumed once a month were salmon, canned tuna, prawns, and take-out fish. Fish/seafood intake and the consumption of foods fortified with n-3 LCPUFA were primarily driven by perceived health benefits, the influence of the media, and the influence of health professionals on health promotion.

Families who eat fish rated taste as having a significant positive impact, as well as the preferences of individual family members, but non-fish eaters perceived these factors as a barrier. For individuals who consume these meals and those who do not, the price was the main deterrent to consuming fresh fish but not canned fish or foods enhanced with n-3 fatty acids.


Whether you are freezing or storing them in your refrigerator, it is important to know how to store prawns to keep them fresh and delicious properly. Prawns are highly perishable in their raw state and should never be stored at room temperature. This can cause a variety of problems, including food poisoning.

If you are storing your prawns in the refrigerator, keeping them in the coldest part is best. This will prevent bacteria from forming. Keeping your prawns cold will also help them last longer.
