Do not eat Shark, Swordfish, King Mackerel, or Tilefish because they contain high levels of mercury. Eat up to 12 ounces (2 average meals) a week of a variety of fish and shellfish that are lower in mercury. Five of the most commonly eaten fish that are low in mercury are shrimp, canned light tuna, salmon, pollock, and catfish. Another commonly eaten fish, albacore ("white") tuna has more mercury than canned light tuna. So, when choosing your two meals of fish and shellfish, you may eat up to 6 ounces (one average meal) of albacore tuna per week. Check local advisories about the safety of fish caught by family and friends in your local lakes, rivers, and coastal areas. If no advice is available, eat up to 6 ounces (one average meal) per week of fish you catch from local waters, but don't consume any other fish during that week.

Counsels on Diet and Foods – Ellen G. White “In many places fish becomes so contaminated by the filth on which they feed as to be a cause of disease this is especially the case where the fish come in contact with the sewage of large cities. The fish that are fed on the contents of the drains may pass into distant waters, and may be caught where the water is pure and fresh. Thus when used as a food they bring disease and death on those who do not suspect the danger.” Pg. 394

May God bless you!
