Onion is what goes bad in the potatoe salad because it attracks bacteria. If you use mayo that is home made then that can go bad but the commercial mayo has preservatives in it. If you put an onion out on the counter when someone is sick and let it there over night you will see how it attracks the bacteria.
Cinco de Mayo is not bad. People might make bad choices in how they celebrate it, but the day itself is not bad.

Mayo Methot went by Sluggy.
Whitman Mayo went by Grady.
look at the expiration date, if its in the jar in the fridge it should last about 2-3 months. if its on a sandwich it should last a few hours, depending on how cool it is. In my opinion mayo can not go bad in 3 to 4 months because of the vinegar that preserves it
its bad
