Mayo is one of the foods where I would be antsy about dates. That is an extremely common cause of food poisoning

  Source? I mean obviously be careful with homemade mayo made from fresh, uncooked egg, but the store bought stuff is pasteurized and seems pretty stable. https://ask.usda.gov/s/article/Does-mayonnaise-cause-foodborne-illness https://ask.usda.gov/s/article/Does-mayonnaise-cause-foodbor...

  Use by dates are only relevant until the product is opened. They usually then have a "consume within" time which is often relatively short.

  not by itself generally. it's too salty and acidic, and the supermarket stuff is often full of edta to boot, so bacteria can't get iron, magnesium, or calcium. mayo diluted with boiled potato is another story also supermarket mayo is labeled as good for months, but salmonella (the usual culprit) can grow in hours. so the sell-by date wouldn't protect you there
