According to the FDA and the USDA, eggs must be fully cooked to prevent foodborne illness due to the Salmonella bacteria. This technically means you also shouldn't be consuming runny egg yolks. However, it is thought that only 1 in 20,000 eggs may be contaminated with Salmonella, so even though there is a risk, it is a very small risk. I have been using raw eggs for years and never had an issue. Just make sure to use the freshest eggs possible with clean shells and without any cracks. If you are still concerned, you can look for pasteurized in-shell eggs at the store or pasteurize your eggs at home.
