If fish is on the menu, you don't have to pass it up entirely to eat safely. New guidelines offer strategies for safe consumption, especially for women who are pregnant or may become pregnant. The F-D-A and E-P-A say more than 90-percent of fish are safe to eat. Elizabeth Southerland with the E-P-A's Office of Water says fish that are safe to eat contain essential nutrients and fatty acids that are beneficial for pregnant women.

"They're a high-quality source of protein, which is especially important for fetal development and for young children. Again, the only concern we have about eating a lot of fish is if you're eating a lot of fish that's high in mercury."

The Michigan Department of Health and Human Services recommends limiting consumption of more than 90 percent of fish caught in Michigan because of mercury contamination.
