Mayonnaise is one of those refrigerator staples that seems to last forever.
You open a jar, use a spoonful for sandwiches or potato salad, put it back in the refrigerator, and forget about it. Weeks later, you find yourself staring at the jar and wondering:
“Is this mayo still safe to eat?”
The answer depends on whether the mayonnaise has been opened, how it has been stored, the date on the package, and whether there are any noticeable signs of spoilage.
While mayonnaise can stay fresh for quite a while when properly refrigerated, it isn't immune to spoilage. Knowing what to look for can help you avoid wasting perfectly good food while also knowing when it's smarter to toss the jar.
