As a salmon lover you’ve likely noticed those thin white lines running through the pink flesh when preparing your fish. The internet is full of conflicting information about what these lines actually are. Some claim they are veins that should be removed. Others insist they are harmless parasites. So what’s the truth about these weird white squiggles in salmon? Let’s explore the facts so you can enjoy salmon with confidence.
Are the White Lines Veins?
Some people firmly believe the white threads in salmon are veins transporting blood However, this is a myth Here’s why
-
Salmon are cold blooded so their blood moves slowly Veins don’t need to be large,
-
Veins contain blood, which would make them appear darker.
-
Veins run internally along bone structures. The lines are visible through the flesh.
-
Fish have a simple circulatory system that doesn’t require extensive veins.
So while salmon do have some blood vessels, the visible white lines are not veins pumping blood.
Are They Parasites?
Many assume the white markings are parasitic worms. This myth likely arose from concerns over salmon parasites like Diphyllobothriumand Anisakis. However, these larger parasites are not the same as the tiny white lines. Here’s why:
-
Parasitic worms would show up as longer, fuller shapes. The lines are very thin and thread-like.
-
True parasites are relatively rare in farmed salmon. The lines show up frequently.
-
Parasites get killed by freezing. The lines persist even in frozen fish.
-
Close inspection shows the lines are part of the fish’s tissue, not separate organisms.
