I didn't make homemade mayo for a long time because I was worried about the raw egg. But then I discovered that you can buy pasteurized eggs, which are safe to eat raw! If you don't want to spend the money on pasteurized eggs, you can pasteurize them yourself - just google it :) Or you can buy good quality cage-free eggs and wash the eggshell to remove any bacteria that might contaminate the egg when broken. However, it's not guaranteed like pasteurized eggs.
