Probably not worms.
What you’re describing with salmon is very commonly albumin, a harmless protein that turns white and squeezes out when fish is cooked—especially if it’s cooked at higher heat or a bit too fast.
What albumin looks like
- White, sometimes slightly thick or gooey
- Can “ooze” or form little beads on the surface
- Often shows up when salmon is baked, pan-seared, or grilled
It’s basically just coagulated protein, not a parasite.
What fish worms would look like (for comparison)
Parasitic worms in fish (like anisakis) usually:
- Look like small, thin, string-like worms
- Are often embedded in raw or undercooked flesh
- Don’t “explode out” when cooking
- Are far less common in properly frozen or farmed salmon (freezing kills them)
Why it happens more with salmon
- High heat causes muscle fibers to contract quickly
- That pressure pushes albumin out
- Overcooking makes it more noticeable
When to worry
You’d only really worry if:
- You saw clear, moving, thread-like shapes before cooking
- The fish had a strong, unusual odor before cooking
- It was undercooked and you noticed suspicious structures inside
Otherwise, white stuff = normal cooking reaction.
Quick tip for next time
Cooking salmon more gently (medium heat, or slightly lower oven temp) usually reduces the white “ooze.”
If you want, describe how it looked or how you cooked it and I can tell you exactly why it happened in your case.
