The issues are manyfold. Farmed fish, including salmon, and other seafood can contain nematodes that aren't killed by freezing in residential freezers. Your best bet is to source seafood from a reputable market, know where it comes from, and that it's sustainable. Wild caught is usually best, with lower parasite levels. https://www.cdc.gov/parasites/anisakiasis https://www.cdc.gov/parasites/anisakiasis https://scdhec.gov/food-safety-freezing-parasite-destruction https://scdhec.gov/food-safety-freezing-parasite-destruction https://www.seafoodwatch.org https://www.seafoodwatch.org

  My understanding is that wild-caught fish have more parasites, but they're required to be frozen for sufficiently long to kill the parasites, whereas farmed fish are exempt from this requirement: From the 2022 FDA Food Code (https://www.fda.gov/media/164194/download https://www.fda.gov/media/164194/download): 3-402.11 Parasite Destruction. (A) Except as specified in ¶ (B) of this section, before service or sale in READY-TO-EAT form, raw, raw-marinated, partially cooked, or marinated-partially cooked FISH shall be: (1) Frozen and stored at a temperature of -20°C (-4°F) or below for a minimum of 168 hours (7 days) in a freezer; [other temperatures/durations elided] (B) Paragraph (A) of this section does not apply to: [...] (4) Aquacultured fish, such as salmon, that: (a) If raised in open water, are raised in net-pens, or (b) Are raised in land-based operations such as ponds or tanks, and (c) Are fed formulated feed, such as pellets, that contains no live parasites infective to the aquacultured FISH.
