Here's What That Creepy White Stuff Coming Out Of Your Salmon Really Is? ›

The white stuff on salmon is called albumin. Albumin is a protein that exists in the fish in liquid form when it's raw, but coagulates and becomes semi-solid when you subject the salmon to heat, whether that's in the oven, on the stove, or on the grill.

The white stuff that oozes out of salmon is called albumin, a type of protein in the fish (other foods with albumin include eggs, beef and milk). You can't see albumin when the fish is raw—it only appears when the salmon is exposed to heat. As salmon cooks, the albumin turns from its liquid state into a semi-solid one.

That white gunk seeping from your salmon is called albumin. It's a protein—not fat—that pushes to the surface of the fish when you heat it. "Once this protein reaches temperatures between 140 and 150 degrees, its moisture is squeezed out, and it congeals and turns white," according to America's Test Kitchen.

Albumin is a flavorless, moisture-rich protein that collects on the surface of salmon as it cooks. It is completely natural and a normal part of the salmon cooking process. Albumin is safe to eat. We can't see albumin in raw salmon, but it becomes visible as the fish is exposed to heat.

That white stuff is called albumin. It's tasteless and totally safe to eat, but it is pretty unsightly.

The white worms we occasionally spot in salmon fillets are parasites called roundworms. Though these worms are more noticeable in salmon due to the contrast in color, they can be found in many white fish too — they're just camouflaged. But we shouldn't be freaking out.

If it's past the date, toss it. Smell: Fresh salmon should have a neutral or mild smell. If the salmon smells fishy, sour or ammonia-like, then it's gone bad. Appearance: Fresh salmon fillets should be bright pink or orange with no discoloration, darkening or drying around the edges.

If you see any type of slimy film developing on your salmon, toss it out.

Tapioca disease, seen here in tiny white cysts in the flesh of a filleted salmon, is a relatively common condition found in salmon. It's neither harmful to the fish nor humans, albeit unsightly.

Compared with farmed salmon and even red king salmon, which tend to be oily and fishy tasting, white king salmon's delicacy is incomparable. ''It's very fine, very delicate,'' said Alain Ducasse.

What is the white slime coming out of my fish? ›

Slime Parasites give your fish a coating of grey/white mucus over the body, the eyes can appear cloudy. It may shimmy, scratch, jump and flick against objects in the aquarium – like it's trying to have a really good itch.

In the cleaning and dressing of fish, surface slime is removed and scales are loosened by submerging fish in a treatment bath of an aqueous solution of common apple cider vinegar, preferably in a concentration of approximately one percent (1%), for a treatment period of five to fifteen minutes, the fish slime being ...

It's called albumin. And it lives in your salmon whether it's cooked or not, no matter where it's from, how it's raised, or how much you paid for it. Albumin is a liquid protein that solidifies when the fish is cooked, seeping out as the muscle fibers contract under heat, becoming thick and a bright white.

Firmness: Cooked salmon should be firm but still moist. When you press down gently on the flesh with a fork or your finger, it should feel slightly resistant but still give way easily. If the salmon is still hard or resists your fork, it needs more time to cook. If it is mushy or falls apart, it may be overcooked.

Raw Salmon Risks You Should Know

Raw or undercooked salmon can be contaminated with bacteria, parasites, and other disease-causing agents. For this reason, the US Food & Drug Administration (FDA) recommends cooking all seafood until it reaches an internal temperature of 145°F.

These white cysts are likely Henneguya but they are somewhat larger than the usual pea or tapioca size lesion. Cysts in general are better diagnosed by breaking them open--if a white, milky fluid oozes out (parasite spores), then it is likely Henneguya.

Henneguya zschokkei or Henneguya salminicola is a species of a myxosporean endoparasite. It afflicts several salmon in the genera Oncorhynchus and Salmo. It causes milky flesh or tapioca disease.
