Is this a parasite?


Saw a bunch of people eating Costco farmed salmon for sashimi, and wanted to try it.
Bought it, portioned it and just to be safe I froze it for more than 10 days (I know it has to be lower than -18c for 7 days, but home freezer definitely can't get that low and just want to be on the safe side)
I took some pieces out, let it thawed and ready to try some. As I was slicing into pieces. I saw a tiny red mark, and I pulled it out. Is this what I think it is? Is this safe to eat?
