How Long Does Raw Fish Last in the Refrigerator?

Raw fish can be a delicate affair, and improper storage can lead to significant quality issues or even foodborne illness. It's crucial to understand how long raw fish can safely be stored before it goes bad in the refrigerator. Here, we cover the science behind the storage time of raw fish, tips for proper storage, and how to tell if your fish is off.

Understanding the Perishability of Raw Fish

Raw fish has a shorter shelf life compared to cooked or processed fish due to the presence of bacteria and its high-water content. When stored at cold temperatures, bacteria can still grow, albeit more slowly. To minimize the risk of harmful bacteria and ensure the best flavor and safety, it's essential to understand the recommended storage time for raw fish.

Storage Time for Raw Fish in the Refrigerator

Experts recommend using raw fish as quickly as possible. For the best quality and safety, it should be used no later than the next day after purchase. If the fish is still in good condition, it can be kept for an additional 24 hours. However, it's crucial not to extend this time beyond two days, as risks of bacterial growth increase.

| Raw Fish Type | Recommended Storage Time |
|--------------|--------------------------|
| Fresh Fish   | Within 1 day             |
| Tuna         | 3-4 days                 |
| Salmon       | 2 days                   |
| Cod          | 2 days                   |

Factors Affecting Storage Time

The storage time of raw fish can vary depending on the type of fish, storage conditions, and how it was handled before refrigeration. Some factors that influence this time include:

Initial Quality: Fish that is already past its prime or has visible signs of decomposition will deteriorate faster. Temperature: Maintaining the refrigerator at 40°F (4°C) or below is crucial to slow down bacterial growth. Package Integrity: Fish wrapped in plastic or sealed packaging can maintain quality longer than loose, exposed fish. Handling: Proper refrigeration and timely preparation can significantly extend storage time.

How to Tell if Raw Fish Is Bad

If you're unsure whether your raw fish is still safe to eat, here are some signs to look for:

Odor: Fish with an ammonia or "fishy" smell is typically a sign of spoilage. Color: A dull or discolored appearance can indicate degradation. Sliminess: Fish that feels slimy or sticky is no longer fresh. Firmness: Press the fish; if it squashes easily, it's likely decomposing.

These signs can provide a good indication of the fish's freshness and safety for consumption.

Proper Storage Techniques

To maximize the shelf life of your raw fish, follow these best practices:

Keep It Cold: Store fish in the coldest part of the refrigerator, typically the bottom shelf. Separate It: Wrap fish in plastic wrap or foil to prevent moisture from other foods and place it on a plate to catch any leaks. Handle With Care: Avoid exposing fish to air or letting juices drip onto other foods in the fridge. Use a Freezer: If you won't be using the fish within a few days, consider freezing it to extend its shelf life significantly.

Conclusion

Remember, while it's best to use raw fish as quickly as possible, understanding the recommended storage times and following proper storage techniques can help maintain the quality and safety of your fish. By keeping these tips in mind, you can enjoy fresh, high-quality fish without the risk of spoilage or foodborne illness.
