Is this salmon safe to eat raw?

I bought some salmon from the market about 3days ago, the guy said it was safe to eat raw, 3days later i decided to eat it, i had refridgerated it, cut open the airtight seal and it was really juicy and wet inside, the salmon tasted beautiful, i still have another fillet left, is this safe to eat, what are the chances of tapeworm? its definatly not poor quality salmon, its a nice even color with no breakage or fishy smell
