The general rule of thumb is that egg salad will keep in the fridge for about 3 to 5 days. But, let's be real, it's all about the storage conditions. If you've got a fridge that's colder than a polar bear's nose, your egg salad might last a bit longer.
Now, you might be wondering what makes egg salad go bad in the first place. Well, it's all about the bacteria and moisture. If you don't store it properly, you'll be inviting all sorts of unwelcome guests to the party. And trust me, you don't want that!
