The most significant risk with eating seafood during pregnancy is that they contain natural pollutants like PCBs (polychlorinated biphenylsiX A group of odorless and colorless synthetic carcinogenic substances ), mercury and dioxins.

5. Do not eat frozen crab meat: Frozen meat should not be consumed as it is prone to bacteria. According to Colorado State University, you can choose crabs stored in a sealed can or a pouch to avoid food-borne illnesses.

6. Handle in a hygienic way: Wash all the cutlery, utensils and food prep area before and after handling the raw crabs. You should use separate knives and cutting boards. Store the leftover food in an airtight container in the freezer. Discard any stale food that has been left out for more than two hours at room temperature.
