How to Store Crab

Storing crab correctly is essential for maintaining its freshness and delicate flavor. Whether you’ve indulged in a seafood feast and find yourself with leftovers, or you’re planning to enjoy your crab at a later date, proper storage techniques will ensure that your crab remains as succulent and tasty as when it was first caught. It’s important to recognize that crabs, whether live or cooked, are perishable and require specific storage conditions to remain safe for consumption.

If you have fresh, live crabs, it’s vital to keep them alive until you’re ready to cook them. Store the crabs in an open container in your refrigerator, lined with a damp newspaper to keep them moist. They must not be kept in standing water or airtight containers because they need air to survive and to prevent them from drowning. Ensure your refrigerator is at the right temperature, ideally between 32 and 35 degrees Fahrenheit, to preserve their freshness.

For cooked crab meat, the approach differs slightly. Use airtight containers to prevent any contamination and to help retain its moist texture. Place the container on ice inside the coldest part of your refrigerator. Avoid freezing the crab meat as it can greatly affect its flavor and texture. By following these steps, you can enjoy the full and rich taste of crab when you are ready to indulge.

Selecting the Right Container

Storing crabs effectively requires the use of suitable containers that provide space and maintain freshness. Here, you’ll learn about which containers serve best and how to prepare them for storage.

Type of Containers

When choosing a container for your crabs, ensure it is spacious enough for the crustaceans to fit comfortably and offers sufficient ventilation to keep them alive if you’re storing them before cooking.

  • Plastic Buckets: A common choice is a plastic bucket, which should ideally have a tightly sealed lid to prevent escapes.
  • Coolers: If you opt for a cooler, it should feature an airtight seal. Coolers are especially good for short-term storage and transport due to their insulating properties.
  • Commercial Crab Containers: There are containers made specifically for seafood storage that often come with built-in features for maintaining the appropriate humidity and airflow.

Container Preparation

Before placing crabs in any storage container, cleanliness is paramount.

  1. Clean: Ensure the chosen container is thoroughly cleaned to prevent contamination.
  2. Dry: Dry the container completely as excess moisture can lead to bacteria growth which can spoil the crab.
  3. Lining: Line the container with damp newspaper or seaweed to keep the crabs cool and moist, especially if storing live crabs.
  4. Plastic Wrap: For storing crab meat, consider wrapping the meat in plastic wrap before placing it in the container to prevent freezer burn if you’re using a freezer for storage.

Remember, your goal in container preparation is to mimic the crab’s natural environment as closely as possible while in storage.

Preparing the Crab for Storage


Properly preparing crabs for storage is essential to maintain their freshness and flavor. Whether dealing with live crabs, freshly caught or already cooked, you’ll want to handle them carefully and cook them appropriately before storage. Make sure to clean the crab thoroughly as well to ensure the best quality when you’re ready to enjoy it later.

Handling Fresh Crab

When handling live crabs, always use care. Use tongs to transfer the crab as they can be aggressive and may cause injury with their claws. Before cooking, keep your live crabs in a cool, moist environment if they’re not going to be cooked immediately. Do not store them in airtight containers or freshwater, as both can be fatal to them.

Cooking Prior to Storage

For optimal freshness, cook your crab before storing. Depending on your preference, you can boil, steam, or grill the crab. Boiling is typically done in a large pot with saltwater for about 20 minutes, depending on the size. Steaming requires less water and preserves more flavor; steam your crab over boiling water for about 20 minutes. Grilling should be over medium heat and will give a smoky flavor. Regardless of the method, ensure the crab is thoroughly cooked; it should reach an internal temperature of 145°F (63°C).

Cleaning the Crab

After cooking, it’s important to clean the crab before storage. Allow it to cool enough to handle, then remove the shell and any undesirable parts, such as the gills and the viscera. Rinse the crab meat with cold water. If you’re storing cooked crab meat, remove it from the shell and claws using a crab cracker and pick. To keep the crab meat at its freshest, place it in an airtight container or wrap it snugly in plastic wrap to minimize exposure to air.

Storing fresh and cooked crab correctly ensures that the flavor and quality are preserved whether you’re opting for refrigeration or freezing. The key is maintaining the right temperature and using the appropriate containers.

Refrigeration Tips

For fresh crab, keep it in the refrigerator at a consistent temperature, ideally just above 32°F to avoid freezing. Store live crabs in a breathable container, like a cardboard box, with wet newspaper or seaweed to maintain humidity levels.

For cooked crabs and cooked crab meat:

  • Place the crab in airtight containers or sealable plastic bags to prevent air exposure.
  • Consume cooked crab meat within 2-5 days.
  • Keep it at the coldest part of the refrigerator.

Freezing Recommendations

When freezing cooked crab:

  • Wrap the crab meat in aluminum foil or plastic wrap.
  • Then, place it in freezer bags to prevent freezer burn.
  • Label the bags with the date to track how long they’ve been stored.

For long-term storage:

  • Frozen crab can last up to three months in the freezer.
  • Store at 0°F or below to maintain quality.

Remember, when thawing frozen crab, do it in the refrigerator overnight and not at room temperature to minimize the risk of bacterial growth.

Maintaining Quality and Safety

When storing crab, it’s important to focus on methods that prevent contamination and spoilage to preserve the product’s taste, texture, and safety for consumption. By managing temperature and observing visual and olfactory cues, you ensure that the crab remains safe to eat and of the highest quality.

Preventing Contamination

To minimize the risk of cross-contamination and the spread of bacteria, always use clean utensils and containers when handling crab. Strict safety measures include:

  • Washing hands thoroughly before and after handling crab.
  • Using separate cutting boards and knives for raw crab.
  • Storing raw and cooked crab separately in the refrigerator to prevent bacterial exchange.
  • Keeping crab in sealed, airtight containers or resealable plastic bags.

Monitoring for Spoilage

Regular checks for spoilage indicators are crucial. Spoiled crab can lead to foodborne illnesses. Be alert for:

  • Foul odor: A strong, unpleasant smell, similar to ammonia, is a clear sign the crab is no longer safe for consumption.
  • Slimy texture: Fresh crab should have a firm texture; if it feels slimy, it has likely begun to spoil.
  • Temperature: Store crab below 40°F (4°C) to inhibit bacterial growth. Use a refrigerator thermometer to ensure consistent temperature.

By adhering to these guidelines, you help maintain the safety and quality of your crab, protecting its flavor and texture while preventing potential health risks.

Additional Storage Considerations

In managing the freshness and flavor of your crabs, consideration of live crab care and labeling for storage duration are pivotal.

Live Crab Care

To maintain the vitality of live crabs before cooking, ensure a controlled environment. Keep your crabs in a moist and cool setting ideally, but don’t immerse them in freshwater or seawater as this can kill them. Storing crabs under a damp cloth or damp seaweed in a refrigerator is a good practice to provide sufficient moisture without submerging them. Use ice packs or a tray of ice to maintain the cool temperature, but always have a barrier to prevent direct contact with the ice to avoid freshwater accumulation. Proper ventilation is crucial; therefore, opt for a container that allows air circulation. It’s important to check on the crabs regularly to ensure the ice hasn’t melted and that they are still alive.

Storage Duration and Labels

Once your seafood is no longer live and has been cooked, deciding the duration of storage and labeling becomes essential. Generally, cooked crab can last in the refrigerator for 3-5 days, but label and date each container to keep track of its shelf life. If you opt to freeze your crab, ensure it’s packed in an airtight container or freezer bag. Label the content clearly with the type of crab and the date of freezing. Frozen crab maintains its flavor for up to three months. Remember that at room temperature, crabs spoil rapidly, so refrigerate or freeze as soon as possible. Adjust your refrigerator’s humidity settings if available, to sustain appropriate moisture levels for optimal storage conditions.

Storing crab involves not just keeping it cold but also ensuring it remains clean and its quality unchanged. Here’s how you can address common issues like debris, odor, and changes in appearance or texture.

Dealing with Debris and Odor

When storing crabs, debris such as sand, dirt, or seaweed can cling to their shells. Begin by rinsing your crabs in cold water to remove any debris. Store them in clean buckets or containers, preferably made of non-reactive materials like plastic, to avoid metallic taste transfer. If you notice an unpleasant odor:

  • Check each crab to ensure it’s still alive and remove any that are not.
  • Clean the storage container with hot, soapy water before returning the crabs to it.

Addressing Discoloration and Texture Changes

Discoloration and texture changes can be indicative of spoilage, but they can also occur due to improper storage techniques. To prevent these issues:

  • Keep crabs at cold temperatures between 32°F (0°C) and 40°F (4°C).
  • If you’re removing the meat, do so in a timely manner and store it in an airtight container in the fridge or freezer.

When crabs are stored properly, they retain their natural color and firm texture, ensuring a pleasant dining experience with this delectable crustacean.

Specific Considerations for Different Crab Types

Before diving into the specific storage considerations for various types of crabs, it’s important to know that each type has different needs to maintain freshness and quality.

Blue Crab Guidelines

When storing blue crab, keeping them alive until cooking is crucial for freshness. If you must store them, ensure your refrigerator maintains a temperature just above freezing (32°F – 40°F). Place them in an open container lined with wet newspaper or seaweed, and cover the container with a damp cloth. Avoid refrigerating live blue crabs for more than 24 hours to ensure they remain in prime condition.

King Crab Tips

For king crab, the legs can often be purchased pre-cooked and frozen, in which case you should keep them frozen until ready to use. Thawing should be done in the refrigerator, and once thawed, they should be consumed within 2 days. If you have live king crabs, follow a similar approach to blue crabs, with emphasis on keeping the storage time as short as possible.

Soft-Shell Crab Pointers

With soft-shell crabs, which are blue crabs that have molted their hard shell, time is of the essence. Store them in a flat pane between layers of moist paper towels inside a rigid air-tight container. They are especially delicate and should be cooked or prepared within 2 days after purchase. If buying pre-cleaned soft-shell crabs, they can also be stored in the freezer with each crab individually wrapped for optimal quality.
