Where Raw Fish Should Go in Your Refrigerator—And Why It Matters

Store raw fish on the lowest shelf, in the coldest part of your refrigerator

Raw fish belongs on the bottom shelf of your refrigerator, in a sealed container or wrapped tightly in plastic wrap. The lowest shelf is coldest because cold air sinks, and it keeps raw fish away from other foods that might be contaminated by drips or bacteria. Fish stored this way will stay safe for one to two days before cooking.

The sealed container does two things at once: it prevents fish juices from dripping onto vegetables, cheese, or ready-to-eat foods below, and it keeps the fish itself from drying out or absorbing odors from other foods in your fridge. If you do not have a dedicated container, wrap the fish tightly in plastic wrap, then place it on a plate or shallow dish to catch any liquid that escapes.

Never store raw fish on a shelf above other foods, even if it is in a container. Refrigerator shelves are not sealed, and condensation or small leaks can still reach the food below. The bottom shelf is your safest choice because anything that drips lands on the shelf itself, not on your groceries.

Key Takeaways

• Raw fish must go on the lowest shelf of your refrigerator, where it is coldest and away from other foods.
• Use a sealed container or wrap the fish tightly in plastic wrap to prevent drips and cross-contamination.
• Raw fish stays safe for one to two days in the refrigerator before the texture and flavor begin to decline.
• If you need to store fish longer than two days, freeze it instead—frozen fish will keep for three to six months.
• Keep raw fish away from ready-to-eat foods like deli meat, cheese, and salads to prevent bacteria from spreading.

Why the bottom shelf is the safest location

Temperature matters more for raw fish than for almost any other food in your refrigerator. Fish contains delicate proteins that break down quickly, and bacteria grow faster in fish than in beef or chicken. The bottom shelf is typically 2 to 3 degrees Fahrenheit colder than the middle shelves, which makes a real difference in how long the fish stays safe to cook.

The bottom shelf also protects everything else in your fridge. Raw fish releases liquid as it thaws and sits, and that liquid carries bacteria like Listeria and Vibrio. If this liquid drips onto lettuce, berries, or cooked chicken below, those foods become unsafe to eat. Storing fish on the lowest shelf means any drips land on the shelf itself, where you can wipe them up, not on other groceries.

If your refrigerator has a meat drawer at the bottom, that is an even better choice than a regular shelf—meat drawers are designed to be colder and to contain spills. If you do not have a meat drawer, the lowest regular shelf works just as well.

How to wrap and contain raw fish properly

The goal of wrapping is to create a barrier between the fish and everything else in your fridge. Start by placing the fish on a clean plate or shallow dish—this catches any liquid that escapes from the wrapping. Then wrap the fish tightly in plastic wrap, pressing it against the fish so no air pockets remain. Air pockets allow bacteria to grow faster and the fish to dry out.

If you have a sealed plastic container with a tight-fitting lid, that is better than plastic wrap alone. Place the fish inside, close the lid firmly, and set the whole container on the lowest shelf. Sealed containers keep odors from spreading to other foods and prevent any liquid from escaping.

For whole fish or large fillets, you can also wrap them in butcher paper first, then place the wrapped fish in a plastic bag and seal it. This double layer gives extra protection. Whatever method you choose, label the container or wrap with the date you bought the fish so you know when to cook it.

How long raw fish lasts in the refrigerator

Raw fish stored on the lowest shelf at 40 degrees Fahrenheit or colder will stay safe for one to two days. After two days, bacteria begin to multiply to unsafe levels, and the texture of the fish starts to break down. The flesh becomes mushy, and the smell becomes noticeably fishy—not the fresh ocean smell, but a sour, ammonia-like odor that signals the fish is no longer safe to eat.

The clock starts the moment you bring the fish home, not when you open the package. If the fish has been sitting in a warm car or on a counter for more than two hours, that time counts against the one to two days. If you are not sure how long the fish has been out of cold storage, it is safer to freeze it or throw it away.

Fatty fish like salmon, mackerel, and sardines break down faster than lean fish like cod or halibut. Fatty fish may only last one day in the refrigerator, while lean fish can last closer to two days. If you bought fatty fish and cannot cook it within a day, freeze it right away.

Keeping raw fish separate from other foods

Cross-contamination is the biggest risk when storing raw fish. Bacteria from raw fish can spread to ready-to-eat foods through direct contact, drips, or even through your hands and utensils. The bottom shelf placement helps, but you also need to be intentional about what you store nearby.

Do not store raw fish on the same shelf as cooked fish, deli meat, cheese, or any food you plan to eat without cooking. If your bottom shelf already holds vegetables or dairy, move those items up one shelf to make room for the fish. The extra effort takes 30 seconds and prevents foodborne illness.

Use a separate cutting board and knife for raw fish, and wash your hands with soap and warm water for at least 20 seconds after handling it. If the cutting board is plastic, wash it in the dishwasher on the hot cycle after use—the heat kills bacteria that survive hand washing. Wood cutting boards should be washed by hand with hot soapy water and allowed to air dry completely.

When to freeze raw fish instead of refrigerating it

If you will not cook the fish within one to two days, freeze it instead. Freezing stops bacterial growth completely and extends the life of the fish to three to six months. Frozen fish will not taste quite as fresh as refrigerated fish when you cook it, but it is still safe and flavorful if you freeze it properly.

To freeze raw fish, wrap it tightly in plastic wrap or place it in a freezer bag, pressing out as much air as possible. Freezer burn—the white, dry patches that form on frozen food—happens when air touches the fish. Removing air slows freezer burn and keeps the fish better. Label the package with the type of fish and the date you froze it.

Thaw frozen fish in the refrigerator overnight, not on the counter. Thawing on the counter allows bacteria to grow in the outer layers while the inside is still frozen. Once thawed, cook the fish within one day. Do not refreeze fish that has been thawed, because thawing allows bacteria to multiply, and refreezing does not kill those bacteria.

Signs that raw fish has gone bad

Trust your senses. Fresh raw fish should smell like the ocean—clean and briny, not sour or ammonia-like. If you open the package and the smell is strong or unpleasant, do not cook it. The smell is a sign that bacteria have multiplied to unsafe levels.

Look at the color and texture. Fresh fish flesh is firm and bounces back when you press it gently with your finger. If the flesh is mushy, dull in color, or has a slimy coating, the fish is no longer safe to eat. Discoloration—dark spots, browning at the edges, or a gray tone—also signals that the fish is past its prime.

If the package is leaking or the wrapping is torn, throw the fish away. Once the seal is broken, bacteria can enter from the outside, and you cannot know how long the fish has been exposed. It is not worth the risk of food poisoning.

Frequently Asked Questions

Can I store raw fish in the refrigerator door?

No. The refrigerator door is the warmest part of your fridge because it is opened frequently and does not have the same insulation as the shelves. Raw fish needs the coldest spot, which is the bottom shelf. The door is fine for condiments and drinks, but not for raw fish.

Is it safe to store raw fish and raw chicken on the same shelf?

It is not ideal, but if both are in sealed containers with tight-fitting lids and the fish is on top of the chicken, the risk is low. However, if you have space, store them on different shelves. If the chicken container leaks, it could contaminate the fish below. Keeping them separate removes that risk entirely.

How do I get rid of the fishy smell in my refrigerator?

Place an open box of baking soda on a shelf away from the fish, or set a small bowl of white vinegar inside. Both absorb odors over a few hours. You can also wipe down the shelves with a cloth dampened in white vinegar after you remove the fish. Storing fish in a sealed container prevents most odors from spreading in the first place.

Can I store raw fish in a regular plastic bag instead of a container?

A regular plastic bag is not ideal because it is not airtight and does not contain spills well. A freezer bag sealed tightly works better than a regular grocery bag. A sealed plastic container with a lid is the best choice because it prevents both drips and odor from spreading.

What should I do if I forgot to refrigerate raw fish for a few hours?

If the fish sat at room temperature for more than two hours, throw it away. Bacteria grow rapidly in raw fish at warm temperatures, and you cannot see or smell the bacteria until it is too late. The cost of the fish is less than the cost of treating food poisoning.
