The USDA recommends cooking salmon to an internal temperature of 145°F (63°C), which is the official safe minimum for all finfish. At this temperature, the flesh is fully opaque, flakes easily with a fork, and any harmful bacteria like Salmonella have been destroyed. That said, many home cooks and professional kitchens pull salmon off the heat well before 145°F for a more tender, moist result.
The Official Safety Threshold: 145°F
The 145°F guideline from the USDA and FoodSafety.gov applies to all whole fish and fillets, including salmon, tuna, cod, and trout. At this temperature, the proteins in the fish have fully set, making the flesh opaque throughout and easy to separate into flakes. This is the number to follow if you’re cooking for young children, older adults, pregnant women, or anyone with a weakened immune system, since it eliminates the common foodborne pathogens found in raw seafood.
Salmon can carry Salmonella, which is the most frequently reported cause of foodborne illness in the United States. These bacteria will not survive if the fish reaches 145°F internally. The trade-off is texture: salmon cooked to this temperature is firm and fully done, which some people find dry compared to salmon pulled at a lower temperature.
What Chefs Actually Cook Salmon To
Most professional kitchens and recipe developers target a significantly lower range. America’s Test Kitchen recommends cooking farmed Atlantic salmon to 125°F and wild salmon to just 120°F. At these temperatures, the center of the fish is still slightly translucent and silky, what you’d call medium-rare. For medium doneness, the range is 130 to 135°F, where the flesh is pink throughout but mostly set.
The reason for the gap between farmed and wild comes down to fat. Wild salmon is far leaner than farmed salmon and has firmer flesh. That lower fat content means it dries out faster as it cooks, so pulling it at 120°F helps retain moisture. Farmed salmon, with its higher fat marbling, can handle five extra degrees without turning chalky.
Cooking salmon below the USDA guideline does carry a small food safety risk, similar to ordering a medium-rare steak. For healthy adults, this risk is generally low, especially with fresh, high-quality fish. But it’s a personal decision worth making with your eyes open.
How to Check the Temperature
An instant-read thermometer is the most reliable way to know when your salmon is done. Insert it horizontally into the thickest part of the fillet, keeping the probe near the center of the flesh rather than touching the skin or the pan. For thinner tail pieces, angle the probe so it stays within the fish long enough to get a reading.
If you don’t have a thermometer, you can press the top of the fillet gently with a finger or the back of a spoon. At around 125°F, the flesh will give slightly and feel soft. At 145°F, it will feel firm and spring back. You can also slide a thin knife or fork into the thickest part and peek: translucent in the center means it’s in the 120 to 125°F range, while fully opaque and flaky means it’s closer to 145°F.
The White Stuff on Your Salmon
If you’ve ever seen white blobs seeping out of salmon as it cooks, that’s albumin, a protein naturally present in the fish. It gets pushed to the surface as the muscle fibers contract from heat. It’s completely harmless and edible, but it does tell you something useful: the more albumin on the surface, the higher the internal temperature has climbed. A lot of white residue usually means the salmon was cooked at too high a heat or for too long.
You can reduce albumin by cooking salmon at a gentler temperature or by brining the fillets in a simple saltwater solution for about 10 minutes before cooking. The salt partially dissolves the surface proteins, so less squeezes out during cooking.
What About Raw or Sushi-Grade Salmon
If you’re eating salmon raw, as in sushi, sashimi, or poke, the safety concern shifts from bacteria to parasites. Wild salmon can harbor roundworm larvae that are killed by cooking but not by refrigeration alone. The FDA’s solution is freezing: holding fish at -4°F (-20°C) or below for seven days, or at -31°F (-35°C) for 15 hours. Commercial sushi suppliers freeze their fish to these specifications before it ever reaches a restaurant, which is why “sushi-grade” is really a handling designation, not a quality grade.
If you’re preparing raw salmon at home, buy it from a fishmonger who can confirm it was frozen to parasite-killing temperatures. A standard home freezer set to 0°F may not get cold enough to meet the seven-day protocol reliably.
Quick Temperature Reference
- 120°F: Medium-rare, best for wild salmon. Translucent center, very moist.
- 125°F: Medium-rare, best for farmed salmon. Silky with a slightly firmer edge.
- 130–135°F: Medium. Pink throughout, mostly set, still juicy.
- 145°F: USDA recommended safe minimum. Fully opaque, flakes easily, firmest texture.
One practical note: salmon continues cooking after you remove it from the heat. Carryover heat typically raises the internal temperature by 5 to 10 degrees, especially with thicker fillets. If you’re targeting 125°F, pull the fish off at around 120°F and let it rest for a few minutes.
