Mummies,
I've done some google on whether can take sashimi... and got these info:
"Women who are pregnant, need to take extra measures to avoid three fairly widespread substances: listeria, mercury, and toxoplasma. Lack of evidence of some bad effects of certain chemicals like sweeteners makes it hard to classify what foods to avoid during pregnancy. When in question, it is better to avoid the particular food and choose a healthier alternate. Of course, consult your gynaecologist if you have any question during pregnancy.
1. Raw Meats: Raw meats such as sushi, seafood (especially shellfish), rare or uncooked beef or poultry foods should be avoided during pregnancy due to the risk of coliform bacteria, toxoplasmosis and salmonella.
2. Deli meats including hot dogs: These deli meats might be contaminated with listeria bacteria which may result in miscarriage. It's safe to eat deli meats if you reheat them until steaming hot or avoid altogether.
3. Raw eggs: Raw eggs may contain salmonella. Some Caesar salad dressings, mayonnaise, homemade ice cream and custards may be made with raw eggs. In addition, unpasteurized eggnog should be avoided during pregnancy. Definitely one of the top foods to avoid during pregnancy.
4. Fish high in mercury: Another important food you can't eat when pregnant. When you consume large amounts of mercury, your baby may suffer brain damage resulting in developmental delays (for example, delays in learning to walk or talk). Consumption of fish containing high levels of PCBs in their fatty tissues is linked to decreased attention, memory, and IQ in babies.
Fish that contain higher levels of mercury include: Shark, Ray, fresh tuna, Mackerel, Grouper, sea bass Moderate mercury: Eastern oysters. Low mercury: Anchovies, king crab, sanddabs, scallops, Pacific salmon; farmed catfish, clams, striped bass."
