Why shouldn't pregnant women eat mayonnaise?

Pregnant women are often advised to avoid mayonnaise made with raw eggs due to the risk of salmonella, which can lead to foodborne illness. Additionally, some commercial mayonnaise may contain unpasteurized ingredients, posing further health risks. However, pasteurized mayonnaise is generally considered safe for pregnant women to consume. It's essential to check labels and choose products that are specifically labeled as pasteurized.
