Now, I know what you're thinking, "What's the magic number?" Well, it's not 7, but more like 3 to 5 days, as I mentioned earlier. This is because devilled eggs are a high-risk food when it comes to bacterial growth, and you don't want to be scrambling to get to the doctor's office with a bad case of food poisoning.
The reason devilled eggs have a shorter shelf life is that they're made with mayonnaise, which is like a magnet for bacteria. And let's not forget the egg itself, which is a breeding ground for salmonella and other nasty bugs. So, it's essential to store them in a sealed container and keep them chilled at a temperature of 40°F (4°C) or below.
Now, you might be thinking, "But I've had devilled eggs in the fridge for a week and they're still fine!" And to that, I say, "Don't count your chickens just yet!" While it's possible that your devilled eggs might still be safe to eat after 5 days, it's not worth the risk. Remember, it's always better to err on the side of caution when it comes to food safety.
