I agree - especially with modern mayo using pasteurized eggs..the vinegar acts as a preservative. It's the boiled eggs, meat, and other stuff IN the product that's using the mayo that spoils.
We made our own mayo at Luby's and most of the volume stores never refrigerated the mayo - it stayed in a lexan in the salad department...of course we used gallons and gallons a day with salad dressings and such - and NO we did not have severe outbreaks of food poisoning!
However, some people will NEVER believe this...and that's OK..better to be safe than sorry.
