The FDA's safe minimum internal temperature for salmon is 145°F, held for 15 seconds. In practice, a wide range gets cooked and served, generally between about 120°F and 145°F, depending on whether the goal is maximum safety margin or a specific, more delicate texture. Knowing where each stop on that range actually lands, and which one is a safety recommendation versus a preference, is the useful part.
Salmon is one of the more debated fish when it comes to temperature, mostly because its texture changes so noticeably across a fairly narrow range. A difference of ten degrees can be the gap between silky and dry, which is why "what temperature" gets a more nuanced answer for salmon than it does for a lot of other proteins.
The full range, from rare to well-done
Rare, under 120°F. The center stays translucent and closer to raw in appearance and texture. This is well below the FDA's safe minimum and carries meaningfully more risk than any of the temperatures below it; it's not a general recommendation.
Medium-rare, roughly 125 to 130°F. The exterior is fully cooked while the center holds a distinctly pink color and a moist, almost silky texture. This is a common target for cooks prioritizing texture, and it's still below the FDA's 145°F safe minimum, a deliberate tradeoff rather than an oversight.
Medium, roughly 135 to 140°F. The center lightens to a pale pink, firmer than medium-rare but still noticeably moist. This sits closer to, but still under, the safe minimum.
Well-done, 140 to 145°F and above. The salmon turns a uniform creamy white throughout, fully opaque with no pink remaining. This is the range that reaches and exceeds the FDA's safe minimum without any of the texture tradeoffs debated at lower temperatures.
Why the FDA number and the common cooking range don't match
The FDA's 145°F guidance is a food-safety recommendation, calculated to reliably address bacterial risk in seafood generally. It isn't a texture recommendation, and salmon's texture happens to change enough across the 120 to 145°F range that many cooks make a deliberate choice to finish somewhere below the full safety number, accepting a specific, informed tradeoff rather than being unaware of the guidance.
This tradeoff depends on starting with fresh, properly handled, properly stored salmon, and it's a choice best made by someone who understands what they're accepting, not a default to follow without knowing the reasoning. For anyone serving salmon to a higher-risk group, including young children, pregnant people, older adults, or anyone immunocompromised, cooking fully to 145°F is the more conservative and appropriate choice, not the lower end of the range.
Why salmon's texture is so temperature-sensitive
Salmon is a fattier fish than most other commonly eaten finfish, and that fat content is part of why its texture shifts so much across a fairly narrow temperature range. At lower temperatures, salmon's fat and connective tissue haven't fully rendered, which produces the silkier, more delicate texture associated with medium-rare. Past about 140°F, the proteins have contracted further and more of that fat has cooked out, producing the firmer, sometimes described as drier, texture associated with well-done salmon.
This is a meaningfully different pattern than a lean white fish like cod or tilapia, which doesn't have as much fat to lose and tends to dry out faster once it passes done, rather than gradually firming up the way salmon does across its wider range.
How to actually hit a specific temperature
An instant-read thermometer inserted into the thickest part of the fillet, not near the thin belly edge, is the reliable way to hit a specific target consistently. The thin edge of a salmon fillet cooks faster than the thicker center, so checking there gives a misleadingly high reading before the rest of the fillet has caught up.
Pulling salmon a few degrees before the exact target and letting it rest briefly accounts for carryover cooking, the residual heat that continues raising the internal temperature for a short time after the fish leaves direct heat. This matters more for a thicker fillet than a thin one, since there's more retained heat working its way toward the center in a thicker cut.
Why sushi-grade or previously frozen salmon changes this calculus
The lower end of the temperature range covered above, particularly anything approaching rare or medium-rare, assumes salmon that's fresh, properly handled, and typically previously frozen to specific standards that address parasite risk, since freezing at sufficiently low temperatures for a specified duration is what FDA guidance relies on to make raw or lightly cooked fish safer. Salmon labeled specifically as sushi-grade or previously frozen for raw consumption has generally gone through this process, while ordinary fresh or frozen salmon sold for cooking hasn't necessarily been treated the same way, since it's intended to be cooked through rather than eaten raw or very lightly cooked.
This distinction matters directly for anyone considering the lower end of the doneness range covered above: choosing to cook salmon to a lower, less-done temperature assumes a level of sourcing and handling that ordinary grocery-store salmon intended for full cooking doesn't necessarily guarantee, which is part of why the tradeoff described earlier depends specifically on starting with fish handled to a higher standard, not just any salmon labeled fresh.
Wild-caught versus farm-raised salmon and temperature
Wild-caught salmon generally has a lower fat content than farm-raised salmon, which affects how it responds across the same temperature range covered above: a leaner wild salmon tends to dry out a bit faster past its ideal point than a fattier farm-raised fillet does, similar in principle to how a lean cut of any protein has less built-in moisture buffer than a fattier one. This doesn't change the FDA's 145°F safe minimum, which applies the same way regardless of whether the salmon was wild-caught or farm-raised, but it's a reasonable factor to account for when choosing where in the texture-preference range to aim for a specific piece of fish.
Knowing which type of salmon you're actually cooking, checked on packaging or by asking a fishmonger directly, helps calibrate expectations for how forgiving a specific fillet will be across the range covered above, rather than assuming every salmon fillet behaves identically regardless of its fat content.
What this looks like on a real menu
Different salmon preparations on a seafood menu often target different points on this range depending on how the dish is built. Atlantic Salmon, served as a standalone entree, is generally cooked closer to the well-done end for a consistent, fully opaque result across a wide range of orders. A dish like Sesame-Soy Salmon built around a bold sauce can sometimes run a touch less done, since the sauce itself adds moisture and flavor that partially offsets a firmer finish. Neither approach is more correct than the other; they reflect different priorities for the specific dish.
For the practical, no-thermometer version of checking salmon doneness by color and texture rather than an exact number, our companion guide on how to know when salmon is done covers those visual cues directly, and our broader breakdown of seafood temperatures generally puts salmon's range in context against other fish and shellfish.
How cooking method interacts with this temperature range
The specific cooking method used to reach a chosen point in this temperature range affects the final result beyond the number alone. Pan-searing and grilling apply direct, intense heat that develops a distinct surface texture and color, browning or char, that a gentler method like poaching or sous-vide doesn't produce, even when both methods are used to hit the identical internal temperature target. This means two pieces of salmon cooked to the exact same internal number, say 130°F for a medium-rare result, can look and taste noticeably different depending on whether that temperature was reached through a hot sear or a gentle poach, since the cooking method shapes the exterior experience even when the interior target is identical.
Choosing a cooking method that matches the desired overall eating experience, not just the target internal temperature, is worth considering alongside the temperature choice itself, since the same internal doneness can be achieved through meaningfully different textural experiences depending on how the heat was actually applied to get there.
Reverse-searing salmon for more control over the final temperature
Reverse-searing, a technique more commonly discussed for steak but equally applicable to salmon, involves cooking the fillet gently at a low oven temperature until it's close to the target internal temperature, then finishing with a very brief, hot sear to develop surface color and texture. This approach offers more precise control over the final internal temperature than a single-stage sear, since the slow initial cooking stage allows for careful, unhurried thermometer checks as the fillet approaches its target, with the final sear serving purely a textural and visual purpose rather than being relied upon to also finish the interior cooking.
This technique is particularly useful for anyone specifically targeting a precise point within the medium-rare-to-medium range covered throughout this guide, since the two-stage process removes much of the guesswork and rushed timing that a single, fast, high-heat method can introduce when trying to hit an exact number.
How salmon's fat distribution varies within a single fillet
Salmon fat isn't distributed perfectly evenly throughout a single fillet, generally concentrated more heavily toward the belly portion and along the fattier streaks visible as lighter-colored lines running through the flesh, compared to the leaner, more uniformly colored sections elsewhere in the same piece. This uneven distribution means a single fillet can actually respond somewhat differently to the same cooking temperature depending on which specific section is being evaluated, with fattier belly sections tending to stay moist and forgiving even as leaner sections of the same fillet begin to firm up and dry at the identical internal temperature.
This is worth knowing specifically for anyone checking doneness at a single point in a larger fillet or a whole side of salmon, since a check taken from a particularly fatty section may not accurately represent how a leaner section of the same piece is actually doing at that same moment.
Salmon color variation between species and how it affects doneness judgment
Different salmon species, king, sockeye, coho, and Atlantic among the most common, naturally carry somewhat different raw color intensities, ranging from a deep, almost red-orange in sockeye to a paler pink in some Atlantic salmon, a natural variation tied to diet and species rather than freshness or quality. This means the specific shade of pink associated with a given doneness level, covered throughout this guide, can look somewhat different depending on which species is being cooked, making the relative color shift, from a wetter, more translucent raw appearance to a drier, more matte cooked one, a more reliable cue across different species than comparing to one fixed reference color regardless of species.
Being aware of this natural species-driven color variation helps avoid a mistaken assumption that a naturally paler salmon species is somehow less fresh or lower quality than a naturally more vividly colored one, when the difference is simply a natural characteristic of the specific species rather than any indicator of freshness or doneness on its own.
The short version: 145°F is the number with no caveats attached. Everything from about 120°F to 145°F shows up in real kitchens as a texture choice, not a mistake, but it's a choice, and it's worth knowing which end of that range you're actually choosing and why.
