I haven't heard anything about pasta salad, but I understand about getting things out of the deli case at your supermarket...
I used to work in a deli in high school and we were required by law to keep temperature logs of all the food cases as to ensure proper refrigeration so that food didn't start growing bacteria. If we failed a temperature test we had to remove all the items out of the case and discard them. If you are worried, you can ask to see the store's temp logs for peace of mind.
Re: Pasta salad
My favorite is full of mayo, too and I'm gonna eat a bunch on Memorial Day. Hooray for mom's macaroni salad! Store bought mayo is safe.
