Can pregnant women eat crab legs and clams/muscles?

Well...: Avoid any shellfish that are raw or undercooked. Do not eat any shellfish harvested during a red tide or when there are similar algae problems. Avoid any fish or shellfish that are obtained from areas near industrial pollution. Avoid smoked seafood. Avoid mecury. Fish with very high potential mercury levels: shark, swordfish, marlin & king mackerel, big eye & ahi tuna & orange roughy. & tilefish.

The new FDA and EPA: guidelines published in 2014 say it is ok. Scavengers like crab and lobtster actually have low levels.Only the predators at the top of the fish-eat-fish food chain concentrate methyl-mercury (from our coal-burning power plants) to dangerous levels. Recent data is best, as we continue to contaminate. Several have a max/wk. http://www.fda.gov/Food/FoodborneIllnessContaminants/Metals/ucm393070.htm
