If you want to eat the eggs that you dyed for just 1 or 2 hours, make sure to refrigerate them immediately after you remove them from the dye. It’s also a good idea to refrigerate the others when they are not being displayed, because they are hard-boiled. If you’ve let the eggs sit in the dye for more than 2 hours, you probably shouldn’t eat them, as bacteria could have started to develop. If displaying the eggs, you can keep them in the refrigerator until it’s time to display them.
