You have options. Pasteurized eggs (the ones in a carton with a label) have already been heated to 140°F for a few minutes—enough to kill salmonella without cooking the egg. You can safely make runny yolks, raw cookie dough, or even aioli with those. But your average farm-fresh egg? Not so much.
If you’re using regular eggs and you absolutely must have that yolk dripping over your toast, you’re gambling. The risk is low—only about 1 in 20,000 eggs is infected—but it’s not zero. Your health, your call. For the rest of us, hitting 160°F is the gold standard.

How To Check (Without Looking Like A Weirdo)
You don’t need a lab coat. Just a good instant-read thermometer. Stick it into the thickest part of the yolk (or the center of a scramble) and wait for the steady beep. 160°F is the target. For baked goods like quiche or frittata, make sure the center reaches that temp, too. And please, don’t just poke a knife in and guess—that’s how you end up with an egg that’s "done" on the outside and raw on the inside.
I’ve learned the hard way that eyeballing a fried egg is like trying to guess the weather in April. One minute it’s perfect, the next it’s a rubber hockey puck. But thermometers don’t lie, and they’ll save your carbonara—and your stomach.
Here’s another twist: the white cooks first because it sets at about 144-149°F. The yolk needs a bit more heat to firm up. So if your egg white is solid but the yolk still jiggles, you’re probably around 150°F. Perfect for a dippy egg, but not quite safe from salmonella’s perspective. See the tension?
The irony is that we’ve been taught to fear raw eggs, yet we blithely eat runny hollandaise, mayonnaise, and tiramisu made with fresh ones. European countries often wash eggs differently than the U.S., so their salmonella risk is actually lower. But you’re reading this in English, so you’re probably dealing with the squeaky-clean (but still risky) American egg system.
So, what’s the bottom line? 160°F kills salmonella in eggs instantly. If you’re cooking them until the white is fully set and the yolk is starting to thicken, you’re likely safe. For runny yolks? Either buy pasteurized eggs or accept the tiny gamble. Me? I now use a thermometer for my carbonara—because a silent, fatal kill-step is better than a loud, regrettable one. Bon appétit, you brave breakfast warrior.
