If Egg salad that was made on Wednesday afternoon must be used or discarded by?

It's generally recommended to use egg salad within 3-4 days of making it, and it should be refrigerated at all times.

Here's why:

* Food Safety: Egg salad can harbor bacteria, especially Salmonella, which can cause food poisoning. Refrigerating it slows down bacterial growth, but it doesn't eliminate the risk entirely.

* Quality: After a few days, the egg salad may become dry, crumbly, and less appealing.

To be on the safe side, it's best to err on the side of caution and discard any egg salad that's been sitting in the fridge for more than 3 days.

If you're unsure, it's always best to check for any signs of spoilage:

* Off-smell: An unpleasant odor is a clear sign that the egg salad has gone bad.

* Color change: The egg salad should maintain a consistent color. If it starts to turn green or gray, it's likely spoiled.

* Texture: The egg salad should be smooth and creamy. If it becomes slimy or lumpy, discard it.

Remember, when in doubt, throw it out!
