FDA Safety Guidance for Salmon
The U.S. Food and Drug Administration (FDA) Food Code states that fish, including salmon, should be cooked to a minimum internal temperature of 145°F (63°C). This temperature is the reference point used by regulators and many restaurant and retail guidance documents to help ensure safety when pathogens are reduced neither by commercial freezing, curing, or other processes. This guidance is widely adopted in food safety plans across the United States.
How to Measure Salmon Temperature Accurately
For a reliable reading, insert a calibrated digital instant-read thermometer into the thickest part of the fillet or steak, avoiding bone or the pan or grill surface. If your cooking method heats from only one side, check the temperature from the side to reach the center. When measuring multiple pieces, check the last piece that is still cooking rather than only the first one done.
Evergreen Factors That Influence Target Temperature
- Thickness and surface area: Thicker cuts take longer for heat to reach the center.
- Starting temperature: Cold-from-the-refrigeration salmon will add cooking time.
- Rest time: Carryover rise can add 5–15°F (3–8°C) after removal from heat, which matters for lean fish.
- Cooking method: Searing, baking, steaming, and sous vide have different heat transfer rates and carryover profiles.
How Carryover Cooking Works
Carryover cooking occurs because heat moves from the outer layers to the center after removal from heat. For salmon, carryover rise is often modest but real; very thick portions can see a higher rise. If your target is medium doneness, pulling the salmon a few degrees before it reaches 145°F can help you land close to 145°F after resting.
Salmon Doneness Temperatures and Sensory Cues
While safety is the primary driver of the 145°F target, many diners also choose a specific final internal temperature based on texture and moisture preferences. Below is a comparison that maps common culinary targets to approximate sensory outcomes. Any time you cook to a lower internal temperature than 145°F, you introduce a potential safety consideration, but many cooks and diners use cues like color, flakiness, and moisture to judge lower-temperature preparation, especially when consuming shortly after cooking.
| Internal Temperature (°F/°C) | Common Name | Texture & Appearance | Typical Use Case |
|---|---|---|---|
| 115–120°F (46–49°C) | Rare | Very rare in many food-safety guidance; very pink, soft, almost raw center | Sous vide with precise control and rapid service |
| 120–130°F (49–54°C) | Medium-rare to medium | Noticeably pink center; tender and juicy; edges opaque | Restaurant-quality sear with a just-warmed-through center |
| 130–140°F (54–60°C) | Medium | Pink center with more flakiness beginning at the edges; core still glossy | Home cooking balancing juiceness and familiarity |
| 145°F (63°C) | Medium-well to well-done per FDA | Nearly or fully opaque; flakes easily; center is firm and barely pink | Food-safety-focused guidance and many restaurant standards |
Practical Cooking Methods and Indicators
How you cook salmon affects when it is done and how you judge it:
- Pan-sear: Start skin-side down in a hot pan with a thin film of oil; finish flesh-side if you prefer less crisp skin. The surface will turn golden and the sides will turn opaque as the heat moves inward.
- Oven roast: Bake or roast at 400°F (200°C) or similar until the thickest point registers 145°F. This method promotes even cooking and is good for portions of varying thickness.
- Poach and steam: Gently simmering in broth or steaming yields a moist, delicate texture; temperatures of the surrounding liquid are typically near 200–212°F (93–100°C) depending on the method. Use a thermometer to confirm the thickest part of the salmon reaches 145°F.
- Sous vide: Bags held at set temperatures like 120–145°F give precise control of final texture. Final sear after sous vide can add browning; note that a post-cook sear does not raise the interior temperature enough to reach safety if the set temperature was below 145°F.
Differences Between Wild and Farmed Salmon
Wild and farmed salmon differ in fat content and nutrient profile, but both should reach the same FDA minimum internal temperature of 145°F (63°C) for safety. Farmed salmon often has more intramuscular fat, which can carry over a bit more heat and remain moist at a given temperature. Wild salmon may cook slightly faster because it typically has less fat. The differences do not change the safety target, but they can affect how quickly you approach carryover rise and how moist the fillet feels at any given temperature.
Tips for Consistency and Safety
Reduce variability and risk by using a calibrated thermometer, checking the thickest portion of the fish, avoiding touching bone or the pan, and allowing a short rest to let the temperature equalize. If you plan to eat salmon rare or medium-rare, consider the source quality, freshness, and whether the preparation method and serving context minimize other risk factors. When in doubt, reaching 145°F is the straightforward, regulator-endorsed choice for safety.
