In this recipe, we are using Raw Egg Whites, just like in traditional French Chocolate Mousse. Raw Egg whites are safe to eat if using Fresh Eggs. That being said, if you do not want to eat raw eggs, you can actually slightly cook them instead. To use pre-cooked Egg Whites, you will need to make an Italian Meringue instead of a French Meringue like here. The difference between the two is that an Italian Meringue is made from a hot sugar syrup poured into egg whites instead of simple caster sugar. Using a hot syrup over the egg whites will not only stabilise them a lot, it will also cook the egg whites. You can read more about Italian meringue here.
