Storing Seafood In The Fridge: Myths and Facts

Clearing up a few myths about storing seafood in the fridge makes it far less intimidating. None of it needs special equipment. Here is a practical look at storing seafood in the fridge for home cooks.

A common myth

It helps to remember that live shellfish need different treatment. Clams, mussels, and oysters must breathe, so they should never be stored in airtight bags or containers or submerged in water. Instead, keep them in a bowl covered with a damp towel. Live lobsters and crabs should be kept cold and damp and cooked the same day.

Small details like salting a few minutes ahead make a visible difference.

What is actually true

Put simply, prevent cross-contamination by keeping raw seafood on a lower shelf, away from ready-to-eat foods, and in sealed packaging so juices do not drip. Before cooking, a quick smell check is useful. Any sour, ammonia-like, or unpleasant odor is a clear sign that the seafood should be thrown away rather than cooked.

It helps to have everything ready before you start, because seafood cooks fast.

Why the myth persists

Seafood is more perishable than most other proteins, so careful storage between the store and the stove makes a real difference in flavor and safety. A few habits keep fish and shellfish in good condition for the short time they spend in the refrigerator.

None of this needs to be exact; thickness and stove heat vary, so trust the visual cues.

A more balanced view

It helps to remember that temperature is the most important factor. Refrigerators should be set at 40°F or below, and the coldest part of the fridge, generally the back of the bottom shelf, is the best place for seafood. Door shelves warm up each time the fridge is opened and are poorly suited for fish.

Small details like salting a few minutes ahead make a visible difference.

What actually helps

Fresh fish fillets and steaks keep best when stored on ice. Place the wrapped fish in a container or zip-top bag and set it on a bed of ice in a shallow dish, replacing the ice as it melts and draining the water. This keeps the fish close to freezing without actually freezing it.

The honest takeaway

On a day-to-day level, as a general guideline, fresh fish should be cooked within one to two days of purchase. Shrimp, scallops, and squid follow a similar timeline. Smoked fish lasts longer, and cooked seafood leftovers are generally best eaten within three to four days.

Practical tips

Some practical points to keep in mind:

• Pull fish off the heat just as it turns opaque.
• Pat fish dry before it goes in the pan.
• Swap fish of similar texture when your first choice is not available.
• Keep a lemon and fresh herbs on hand to finish dishes.

The bottom line

The best seafood dish is the one you feel confident making again. Keep it simple, watch the cues, and do not rush the prep. That is really all it takes.
