Potato salad expiration: how long can potato salad really sit out?

Potato salad is a classic summer dish that is perfect for picnics, potlucks, and barbecues. However, one of the most common questions about potato salad is whether or not it can be left out. The answer to this question depends on a number of factors, including the temperature, the ingredients, and how the potato salad is stored.

How Long Can Potato Salad Be Left Out?

The general rule of thumb is that potato salad should not be left out at room temperature for more than two hours. This is because the mayonnaise in the potato salad can start to spoil at room temperature, which can lead to food poisoning.

However, there are a few exceptions to this rule. If the potato salad is made with a vinegar-based dressing instead of mayonnaise, it can be left out at room temperature for up to four hours. Additionally, if the potato salad is stored in a cooler with ice packs, it can be left out for up to six hours.

What Happens if Potato Salad Is Left Out Too Long?

If potato salad is left out at room temperature for too long, the mayonnaise can start to spoil. This can lead to food poisoning, which can cause symptoms such as nausea, vomiting, diarrhea, and abdominal cramps.

In some cases, potato salad that has been left out too long can also develop botulism. Botulism is a serious illness that can be fatal. Symptoms of botulism include double vision, blurred vision, difficulty swallowing, and muscle weakness.

How to Store Potato Salad Safely

To store potato salad safely, it is important to keep it refrigerated at all times. The potato salad should be stored in an airtight container to prevent it from drying out. If the potato salad is made with mayonnaise, it is important to keep it refrigerated for no more than three days.

What to Do if Potato Salad Is Left Out Too Long

If you accidentally leave potato salad out at room temperature for too long, it is important to discard it immediately. Do not eat potato salad that has been left out at room temperature for more than two hours.
