Overview
Crab is a popular seafood choice that can be part of a healthy pregnancy diet when prepared correctly. According to FDA guidelines, most crab varieties are low in mercury, making them a safer seafood option compared to high-mercury fish like swordfish. ACOG supports moderate seafood consumption for omega-3 benefits that support fetal brain development.
Safety Details
The primary risks with crab include mercury exposure and bacterial contamination such as listeria if the crab is raw or improperly handled. Fully cooked crab poses minimal risk. Studies show that cooked crab contains less than 0.1 ppm mercury on average, well below the FDA's 0.46 ppm action level for vulnerable groups. Always avoid raw crab meat or crab salads from deli counters due to potential listeria, which can cause miscarriage or preterm labor.
Key Data Points
