Raw fish can be stored in the refrigerator for a limited time, and it is generally not recommended to keep it for seven days. The freshness and safety of raw fish can deteriorate quickly, and after a certain point, it may become unsafe to consume.
The recommended storage time for raw fish in the refrigerator is typically between 1 to 2 days. During this time, the fish should be kept at a temperature of 32°F to 38°F (0°C to 3°C) to slow down bacterial growth. However, this time frame can vary depending on the type of fish and its initial freshness.
If you plan to store raw fish for an extended period, it is better to freeze it. When properly frozen at 0°F (-18°C) or below, fish can maintain its quality and safety for several months.
Always use your best judgment and inspect the fish before consuming it. If the fish looks or smells off, or if you have any doubts about its safety, it's better to err on the side of caution and discard it. Consuming spoiled fish can lead to foodborne illnesses, which can be serious.
