NO!

Mayonnaise contains raw egg whites, which will spoil if left as long as overnight. You can leave it out for a max of an hour, but overnight is definitely ruined. If you ate mayonnaise after it is left out and feel queasy, you should consult a doctor.

Hope you didn't... :-)

Food left out of the refrigerator is okay to eat for about 2 hours. If the temperature is under 80 degrees. The longer a food stays in the danger zone the more risk you take eating that food. Foods should either be kept hot or kept cold before eating to be really safe.

"NO! No food can be kept out that should be refrigerated longer then 4 hours. Mayonnaise is one of the worst I wouldn't want to eat it if it had been left out 2 hours. If it is a unopened bottle then yes it can be left out till the best before date but after NO NO NO!"

Actually, if it commercially produced mayonnaise, it may not be as bad as you think. See below, excerpted from the State of Alaska Department of Environmental Health Food Safety and Sanitation Program's website:

Myth #15 - "Mayonnaise is the dangerous ingredient in potato salad."

In reality, it is the potatoes and eggs in potato salad that can cause foodborne illness. The mayonnaise actually acts as a preservative which protects the potato salad. Commercially purchased mayonnaise is pasteurized and has a high acid content that actually slows bacterial growth. Home-made mayonnaise, which is made with raw eggs, is not safe and should be avoided.

To keep your potato salad safe:

  • Start with fully cooked and quickly cooled potatoes and eggs;
  • Use commercially purchased mayonnaise; and

Keep the potato salad cold.

assuming there was a lid on the mayonaisse, it should be fine as long as you put it back in the fridge once you realized it was left out.
