Short answer: Eat only fully cooked eggs. Do not eat raw eggs or preparations containing raw eggs.
Eggs are full of protein and calcium and are especially recommended for pregnant women. But raw eggs or any foods that contain raw eggs should be avoided because of the potential exposure to salmonella. Some items like mayonnaise in sandwiches and burgers, some salad dressings like Caesar dressings etc. are made with raw eggs and it’s best to avoid them when you are pregnant.
When you are buying eggs, make sure to check the date on them.
