Mahi Mahi and Mercury Level

Thanks to my sister's friend who lives in Massachusetts, I will stop eating mahi mahi as long as I am nursing DD2. She alerted my sister that mahi mahi contains mercury and my sister told me about it this morning. My mother said that now I can start eating chicken without worrying my wound getting infected, so I've asked husband to get some for me today.

Here is what I found on the American Pregnancy Association web site:

For information regarding other types of fish, the Natural Resources Defense Council (NRDC) has released a list of fish and their mercury levels so that people can be informed on what they are consuming. If you want to get more detailed information about mercury levels and how much you personally are consuming, you can also use the mercury thermometer to calculate your totals.

Consumer Guide to Mercury in Fish

The list below shows the amount of various types of fish that a woman who is pregnant or planning to become pregnant can safely eat, according to the Environmental Protection Agency. People with small children who want to use the list as a guide should reduce portion sizes. Adult men, and women who are not planning to become pregnant, are less at risk from mercury exposure but may wish to refer to the list for low-mercury choices.

Protecting yourself -- and the fish: Certain fish, even some that are low in mercury, make poor choices for other reasons, most often because they have been fished so extensively that their numbers are perilously low. These fish are marked with an asterisk (read more below).

This list applies to fish caught and sold commercially. For information about fish you catch yourself, check for advisories in your state.

* Fish in Trouble! These fish are perilously low in numbers or are caught using environmentally destructive methods. To learn more, see the Monterey Bay Aquarium and the Blue Ocean Institute, both of which provide guides to fish to enjoy or avoid on the basis of environmental factors.

** Farmed Salmon may contain PCB's, chemicals with serious long-term health effects.

Sources for NRDC's guide: The data for this guide to mercury in fish comes from two federal agencies: the Food and Drug Administration, which tests fish for mercury, and the Environmental Protection Agency, which determines mercury levels that it considers safe for women of childbearing age.

About the mercury-level categories: The categories on the list (least mercury to highest mercury) are determined according to the following mercury levels in the flesh of tested fish.

• Least mercury: Less than 0.09 parts per million
  
• Moderate mercury: From 0.09 to 0.29 parts per million
  
• High mercury: From 0.3 to 0.49 parts per million
  
• Highest mercury: More than .5 parts per million
