When it comes to consuming raw salmon, food safety is of the utmost importance. Salmon is a popular choice for sashimi and sushi lovers, but its delicate flavor and texture can quickly turn into a breeding ground for harmful bacteria if not stored and handled properly. So, how can you tell if raw salmon has gone bad?
Understanding the Risks of Spoiled Salmon
Raw salmon is a high-risk food due to its high water content and fatty acid composition. When salmon spoils, it can become a haven for bacteria like Salmonella, Listeria, and E. coli, which can cause serious foodborne illnesses. In fact, the Centers for Disease Control and Prevention (CDC) estimates that every year, 48 million people in the United States get sick from foodborne illnesses, resulting in 128,000 hospitalizations and 3,000 deaths.
Visible Signs of Spoilage
One of the most obvious ways to determine if raw salmon has gone bad is to look for visible signs of spoilage. Check the salmon for the following:
- Slimy or soft texture: Fresh salmon should have a firm, meaty texture. If it feels slimy or soft to the touch, it’s likely gone bad.
- Unpleasant odor: Fresh salmon should have a mild, slightly sweet smell. If it smells strongly of ammonia, fishy, or sour, it’s likely spoiled.
- Discoloration: Fresh salmon should have a bright, vibrant color. If it has turned dull, grayish, or brown, it’s likely gone bad.
- Bloody or rusty spots: If you notice any bloody or rusty spots on the salmon, it may be a sign of spoilage.
Other Signs of Spoilage
In addition to visible signs of spoilage, there are other ways to determine if raw salmon has gone bad. Check the salmon for the following:
- Sour or bitter taste: If the salmon tastes sour or bitter, it’s likely gone bad.
- Slimy or cloudy eyes: Fresh salmon should have clear, bright eyes. If the eyes are slimy or cloudy, it’s likely spoiled.
- Rancid or sour smell: If the salmon smells rancid or sour, it’s likely gone bad.
How to Store Raw Salmon to Prevent Spoilage

What are the signs of spoiled raw salmon?
The signs of spoiled raw salmon can vary, but some common indicators include a slimy or soft texture, an off smell, and visible signs of mold or mildew. Fresh salmon should have a firm, dense texture and a mild, slightly sweet aroma. If the salmon has a strong, fishy smell or visible signs of spoilage, it’s best to err on the side of caution and discard it.
It’s also important to check the salmon’s expiration date, if it’s available, and to only purchase from reputable sources. Fresh salmon should also have a glossy, vibrant color and firm, intact skin. If the skin is dull, slimy, or has visible signs of damage, it may be past its prime. By paying attention to these signs, you can help ensure that you’re getting the freshest, highest-quality salmon possible.
How long does raw salmon last in the fridge?
The shelf life of raw salmon in the fridge depends on several factors, including the freshness of the salmon when it was purchased, how it’s stored, and the temperature of the fridge. Generally, raw salmon can last for up to three days in the fridge, but it’s best to consume it within a day or two for optimal flavor and texture.
It’s also important to store the salmon properly to help extend its shelf life. Make sure it’s wrapped tightly in plastic wrap or aluminum foil and kept at a consistent refrigerator temperature of 40°F (4°C) or below. If you notice any signs of spoilage, such as an off smell or slimy texture, it’s best to discard the salmon immediately, even if it’s within the three-day window.
Can I freeze raw salmon to extend its shelf life?
Yes, freezing is a great way to extend the shelf life of raw salmon. Frozen salmon can last for up to six months when stored properly. When freezing, make sure to wrap the salmon tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. It’s also important to label the bag with the date it was frozen and to store it at a consistent temperature of 0°F (-18°C) or below.
When you’re ready to use the frozen salmon, simply thaw it in the fridge or under cold running water. Once thawed, use it immediately, as frozen salmon can develop an off flavor and texture if thawed and re-frozen.
How do I properly store raw salmon in the fridge?

What happens if I eat spoiled raw salmon?
If you eat spoiled raw salmon, you risk getting food poisoning from harmful bacteria like Salmonella, Listeria, or Clostridium botulinum. These bacteria can cause symptoms like nausea, vomiting, diarrhea, stomach cramps, and fever. In severe cases, food poisoning can lead to hospitalization or even death, especially in vulnerable populations like the elderly, pregnant women, and people with weakened immune systems.
To avoid getting food poisoning, always prioritize food safety and handle raw salmon with care. Make sure to purchase from reputable sources, store it properly, and check it for signs of spoilage before consumption. If in doubt, it’s always better to err on the side of caution and discard the salmon to avoid any potential health risks.
Can I use expired raw salmon?
No, it’s not recommended to use expired raw salmon. The expiration date on the packaging is a guideline for the retailer, indicating when the product should be pulled from the shelf. Consuming expired raw salmon can increase your risk of foodborne illness, as bacteria can multiply rapidly on perishable foods like fish.
Even if the salmon looks and smells fine, the risk of spoilage increases with time, and the quality of the fish decreases. To ensure food safety and quality, always use fresh raw salmon within the recommended time frame and check it for signs of spoilage before consumption.
Can I tell if raw salmon has gone bad by its smell?
Yes, a strong, unpleasant smell is one of the most noticeable signs of spoiled raw salmon. Fresh salmon should have a mild, slightly sweet aroma. If the salmon has a strong, fishy smell, ammonia-like odor, or any other unpleasant smell, it’s likely gone bad and should be discarded.
However, it’s important to note that smell alone may not always be a reliable indicator of spoilage. Some types of salmon, like wild-caught sockeye, may have a naturally stronger flavor and aroma than farmed salmon. If you’re unsure about the smell or freshness of the salmon, it’s always best to check it for other signs of spoilage, such as texture and color, before making a decision.
