Macaroni salad still good?
I made a macaroni and tuna salad with vegetables and such .. now , I used mayo in the mix like a lot of people do . I had it with my supper , immediately covered it with tinfoil in the big bowl however I fell asleep early and it was out for quite a bit of hours .. like 6 hours covered so I threw it back in the fridge but when I got to thinking about the mayo I thought ... yeah , even though it's lunch time .. maybe I should discard this salad and find something else to eat . What do you think? any links to any sound advice that's not yahoo answers LOL some people say after an hour its garbage and some say commercial mayo has lots of preservatives in it so it's different but I cant decide .
