Commentary:    I found this article to be very appropriate for my obstetrical patients and those who want to be pregnant someday.  This topic covers a issue which comes up in my OB practice several times a week.  Are fish safe to eat during pregnancy?  Better question after reading this article would be.   Should I be aware of certain fish consumption before I get pregnant as well as after I’m pregnant?  According to this article from the F.D.A., the answer would be yes.  After reading this article, I was impressed with the data presented on the mercury levels that were present in different fish.      Doc’s take on this article is that it does clear up some previous concerns about mercury and fish.  One minor deficiency with this article was that it does not include all specific deep-water fish that people eat.  Is a Chilean sea bass safe to eat?  I just love that fish.  Is that the same as saltwater bass?  I also concluded from this article that the longer the fish lives the more dangerous it is to eat.  Those fish have more years to accumulate this methyl mercury in their systems.  I also concluded that a shark, which is a predator, feeds on other fish.  These fish that are eaten have had time to accumulate their share of methyl mercury.  The shark builds up the methyl mercury exponentially because of their feeding habits.    In conclusion, avoid consumption of shark, swordfish, king mackerel and tilefish.   I’ll continue to eat my sea bass.  Doc
