Should i be worried about mercury in fish if feeding my fmaily?

Yes: We should all worry about mercury as it is a toxin. Swordfish and mackerel are two that are known to be pretty high in mercury as is tuna. So the it is best to eat these kinds of fish no more than once a week. Try and get wild caught fish as much as possible. Look for fish that are not known to be high in mercury. Salmon is still a good bet as is sea bass, snapper, trout, grouper.

Mercury in fish: Big eye & ahi tuna should be avoided due to high mercury level. Yellow fin & white albacore tuna intake should be limited. Skipjack & canned chunk light tuna have a lower amount of mercury. **fish with very high potential mercury levels include: shark, swordfish, marlin, king mackerel, big eye & ahi tuna, orange roughy & tilefish. Limit intake of yellow fin and white albacore tuna. Cont'd.
