Can You Refreeze Shrimp? Here’s How to Do It Safely

In terms of versatility, shrimp have the potential to outperform any other seafood.

After all, they are easy to prepare, quick, filling, and versatile enough to be served warm or cold, poached or grilled, as a rich, colorful garnish, or as the main course all on their own.

In most seafood markets, you can purchase them frozen, fresh, or previously frozen, which begs the question: can you refreeze shrimp that has been previously thawed?

The answer may surprise you.


Shrimp Consumption in the United States

According to the South Florida Reporter, the yearly shrimp consumption by the typical American amounts to 4.0 pounds (4lbs each, which equals one billion pounds) (1).

In context, this is a portion of the 15.5 pounds of seafood consumed annually by individuals in the United States. After shrimp, the most popular seafood choice is salmon (2.3 pounds), followed by canned tuna (2.3 pounds).

Nearly all Americans have a good stock of shrimp in the freezer.

And why on earth not?

Nothing is better than having frozen shrimp ready to be cooked whenever you want them. They are simple to prepare, have a mouthwatering flavor, and contribute positively to one’s health.

And regardless of what you are preparing, adding shrimp will dramatically transform the meal’s appearance and taste.

There are times when individuals defrost more than needed; thus, the dilemma is what to do with the leftover.

Can you freeze them again?

Are they safe for later consumption, even after being frozen again? So, refreezing thawed seafood generally poses a potential risk, but if you understand and adhere to the necessary procedures, you’re good to go.


Can You Refreeze Shrimp? – An Overview

Here’s a quick answer to Can you refreeze shrimp question. Yes, you can refreeze previously thawed shrimp.

If you thawed them in the refrigerator, you might easily put them back in the freezer. However, suppose they were defrosted at room temperature under cold running water or microwave.

In that case, you will need to cook them fully within a day or two before freezing to ensure food safety.

What Happens When You Refreeze Food?

Generally, when you refreeze any food item, it directly affects the flavor and texture; however, by following the standard freezing method (consistent refrigerator-like temperature), these alterations may be kept to a minimum (2).

On the other hand, there are certain items in which the freezing process has a greater impact on the food’s overall quality, especially raw and cooked meat and seafood.

Additionally, the cell walls of the food also begin to rupture due to the low temperature of the freezer, and as a direct result, the meal’s consistency shifts.

But, the cells experience yet another round of harm when food is thawed and frozen, leaving it susceptible to bacterial development, particularly the one high in protein.

This is why food businesses, including restaurants and grocery shops, are subject to legislative requirements that regulate freezing and thawing conditions (3).


Can You Refreeze Shrimp Thawed Shrimp?

As discussed above, you can refreeze previously thawed shrimp; yet, it depends on the defrosting method and the duration.

If you let the shrimp thaw at room temperature or under cold running water, don’t put it back in the freezer.

Similarly, you shouldn’t refreeze shrimp after defrosting in the microwave since repeating the process of exposing the shrimp to cold temperatures will cause significant changes to take place in the texture.

On the other hand, shrimp that has been out in the open air for an extended period is more likely to get contaminated with germs.

Therefore, it may only be frozen again for later use after being defrosted in the refrigerator. In addition to the defrosting method, it is essential to consider the time duration.

The golden rule is to refreeze the shrimp as soon as possible after they have been cooked.

Be aware that shrimp is virtually always available in seafood stores and supermarkets in a frozen state. After that, it is defrosted and presented as if it were new.

So, if you ever buy shrimp in its fresh form, knowing there is only a little possibility for it to be truly fresh, don’t risk refreezing it.

Always purchase as much shrimp as you need to cook for the day, and go with a frozen package if you want it to survive for a longer period.


Step-by-Step Guide to Refreezing Shrimp

Refreezing shrimp is not the best course of action; however, you can still do it if you thawed more shrimp than needed.

Here’s a step-by-step guide on refreezing shrimp defrosted in the fridge.

  • First, ensure the shrimp hasn’t been out of the freezer for more than two days.
  • Then, inspect the shrimp to see if it has gone bad (more on this later!).
  • If the shrimps still have their protective shells on, don’t remove them.
  • If the shrimp have leaked water due to thawing, carefully strain them.
  • Put them in a bag or container with a zip-top lid and seal tightly.
  • Finally, label the shrimp container before to avoid over-freezing.

If you thaw the shrimp in the refrigerator and then refrozen it within a day or two, you should be able to refreeze them at least once before throwing them away.

Additionally, thawing and refreezing shrimp more than once is not something we recommend. It will not only significantly impact the shrimp’s consistency, appearance, and flavor but also make it unsafe for consumption.


How Does Refreezing Affect Shrimp?

Like other sea foods or meat, shrimp faces deterioration in its consistency, taste, and overall quality after being thawed and refrozen.

Consecutively, it is common for thawed shrimp to have a lower moisture content.

If, on the other hand, your freshly-bought shrimp gets a “freezer burn” (more on this later!), this will significantly impact its consistency, appearance, taste, and color.


What is a Freezer Burn?

Freezer burn is a state in which the frozen food faces discoloration or other damage due to evaporation, often resulting from improper packing or storage conditions (4).

In other representations, freezer burn typically results from a chemical reaction called “sublimation,” where the food loses its moisture content after being stored in the refrigerator for an extended period (5).

The drying out of the food causes dehydration and oxidation, which has a direct impact on both its taste and texture.


Signs of Freezer-Burned Shrimp

According to the Food Safety and Inspection Service, freezer burn is not always a sign that food is harmful to eat but is mostly a quality issue; however, it is still crucial to note the symptoms (6).

If your shrimp is opaque or has white patches, it could have been burned in the freezer. On the other hand, some symptoms include tough, dry, or chewy texture, unpleasant odor, and loss of flavor.


How to Prevent Freezer-Burn?

A significant factor is ensuring that they are handled appropriately from being purchased at the store until consumed.

The following steps should be taken to prevent shrimp from freezer burn.

  • Once you arrive home, sort the shrimp and put them in the refrigerator.
  • Add another seal on the package just in case to prevent air from leaking in.
  • To avoid over-freezing, label the container before putting it in the freezer
  • Place them at the back of the refrigerator, which is often the coldest part.
  • Keep them frozen at 0°F for the best quality and use within 3-6 months.


How to Tell If Shrimp Have Gone Bad?

First things first, always do a quality check the shrimp before you use it, particularly if you have thawed it before.

While it is much simpler to determine whether or not shrimp has gone bad once it has been thawed, you could easily overlook some common symptoms.

Avoid purchasing frozen shrimp packaged in a ripped or otherwise damaged container. Secondly, avoid shrimp that can be bent without breaking.

And as a last piece of advice, throw away the shrimp immediately if you find that the box has developed any strange discoloration or mold.

With that said, the best way to determine whether or not frozen shrimp has gone bad is to defrost it first. After the shrimp has been allowed to thaw, give it a whiff.

A fine shrimp would always have a little smell of the sea; instead of an off-putting, strong fishy, or ammonia smell.

Finally, check the color of the meat; it should be white with a slimy texture, not pink, under any circumstances.


The Final Cut

So there you have it: answer to the most searched question on the Internet about shrimps, How to refreeze thawed shrimp safely.

Now that you’re all set, ensure to defrost them in the refrigerator or by placing them under cold running water, and then proceed to cook as you normally would.

If your shrimp smells fishy or ammonia-like, it has probably gone bad.

But, if you’re still unsure whether they can be consumed, it’s always best to err on caution and throw them away immediately.
