Final answer:
The EPA recommends avoiding high-mercury fish like swordfish and shark, and instead choosing low-mercury fish like salmon and shrimp. They do not provide an exact number of servings per week, but suggest consuming a variety of seafood.
Step-by-step explanation:
The United States Environmental Protection Agency (EPA) recommends that pregnant women and young children should not consume swordfish, shark, king mackerel, or tilefish due to their high mercury content. These individuals are advised to eat fish low in mercury, such as salmon, tilapia, shrimp, pollock, and catfish. The EPA does not specify an exact number of fish servings per week, but the general guideline is to choose fish low in mercury and consume a variety of seafood.
