Mayonnaise is one of the most confusing foods during pregnancy. Some sources say it’s perfectly safe. Others say it’s dangerous because of raw eggs.

So what’s the truth? Commercial mayonnaise like Hellmann’s is 100% pregnancy-safe because it is made with pasteurised eggs and has a high-acid recipe that prevents bacteria like Salmonella and Listeria.

But homemade mayo or restaurant-made mayo may contain raw eggs — which can be unsafe in pregnancy. This guide gives you the exact rules to enjoy mayo safely.
