Can You Refreeze Shrimp? Is It Safe?

Can You Refreeze Cooked Shrimp?

While refreezing raw shrimp is a better option, you can refreeze cooked shrimp.

It is better to take out the amount you want to cook from the freezer to cook shrimp, so there is no need to freeze it again.

Remember to wait for the cooked shrimp to fully cool before refreezing which helps reduce the possibility of freezer burn - a condition where frozen food exposed to air becomes dry and discolored.

Also, you must carefully pack and store shrimp in the freezer, as improper refreezing can change its flavor and texture. Here are the steps to refreeze it properly.

How to Refreeze Shrimp?

The following instructions can help refreeze shrimp without losing quality.

1. Divide the shrimp into small portions based on the amount you want to use in one meal.
2. Place each portion into airtight containers or plastic bags.
3. Remove as much air as possible to prevent freezer burn. You can use a vacuum sealer or manually press the air before sealing.
4. Place the shrimp in the freezer at 0°F (-18°C) or below.
5. Use within two months after freezing because its texture and taste will change after that.

Remember that freezing and refreezing shrimp multiple times can damage them, changing their flavor and texture and increasing the likelihood of bacterial growth. So, how many times can you refreeze shrimp?

How Many Times Can You Refreeze Shrimp?

When you refreeze shrimp that was previously frozen, the cell walls break down, and the moisture inside turns into ice crystals.

So, it’s best to refreeze shrimp only after it has been thawed once and is still in good condition, with a fresh smell, firm texture, and no signs of spoilage.

Refreezing is fine if you’re using shrimp as chopped or minced in dishes like shrimp burgers or potstickers, i.e., chopped shrimp (not whole shrimp) can safely be refrozen multiple times because its texture and taste won’t change much.

After refreezing, you need to thaw shrimp properly to avoid bacterial growth and keep its quality. Improper thawing can make shrimp mushy or rubbery.

How to Thaw Frozen Shrimp?

You can use the following methods for thawing shrimp:

• Refrigeration: The best way to thaw shrimp is to put it in the refrigerator overnight. Put the frozen shrimp in a colander or strainer over a bowl to catch any liquid that drips as it thaws. Cover the bowl to avoid contamination from other food. Thawed shrimp can be kept in the refrigerator for up to two days before cooking.
• Using Cold Water: To speed up the thawing process, you can put the shrimp in a leak-proof bag in cold water. Change the water every 30 minutes until the shrimp is completely thawed, which takes about 10-20 minutes, depending on the quantity. Once thawed, cook the shrimp immediately.
• Using a Microwave: Using a microwave to thaw shrimp is not recommended because it can cause uneven thawing. If you must use a microwave, use the defrost setting and follow the manufacturer’s instructions carefully.

While refreezing shrimp keeps them fresh longer, it can also be dangerous if refrozen many times and not wrapped properly. Let’s see what these risks are and how can they affect us.

Why Refreezing Shrimp Could Be Dangerous?

Refreezing shrimp can be dangerous for several reasons, including

• Bacterial Growth,
• Loss of Quality,
• Freezer Burn, and
• Nutrient Loss.

These risks are rare, especially if you properly wrap and refreeze the shrimp. However, it's essential to know how to avoid them.

Bacterial Growth

Shrimp are susceptible to bacterial growth, such as pathogens like Vibrio, which grow in seafood.

When shrimp is thawed at room temperature or thawed improperly, bacteria can multiply rapidly. Refreezing can allow these bacteria to survive, increasing the risk of foodborne illnesses like food poisoning [1].

Loss of Quality

When you freeze and thaw shrimp, their texture and flavor differ from the fresh shrimp. Ice crystals that form during freezing can damage the shrimp's cell structure, making it mushy and causing it to lose its natural texture and flavor [2].

If you must refreeze shrimp, do it immediately after thawing in the refrigerator. Use airtight containers or vacuum-sealed bags to minimize exposure to air and ice crystal formation.

Freezer Burn

Freezer burn is when frozen food becomes dried out and dehydrated because of improper freezing or air exposure. It affects all foods but happens faster to those with high moisture, like meats and fruits [3] [4].

To prevent freezer burn, pack your food properly using airtight containers or freezer bags, removing as much air as possible to help it last longer.

Nutrient Loss

Although it rarely happens, refreezing can lead to nutrient loss in shrimp, particularly water-soluble vitamins like B [5].

Consume shrimp quickly after purchase or initial thawing to minimize nutrient loss. Store shrimp in the freezer at or below 0°F (-18°C) to maintain nutritional values.

Conclusion

So, to wrap up, can you refreeze shrimp? Yes, you can refreeze both raw and cooked shrimp using proper thawing and refreezing methods, such as cold water or refrigerating overnight.

Also, if you see signs such as a slimy texture or grayish color, it can mean that the shrimp has been spoiled. If this happens, don't eat or refreeze it. Just throw it away in a sealed bag to prevent contamination.
