Mayonnaise has been wrongly accused for years. At picnics, potlucks, and family barbecues, it’s the first thing people blame when someone gets sick. But what if the real danger isn’t the mayo at all?

Mayonnaise’s bad reputation hides a quieter truth: commercial mayo is built to be safe. Made with pasteurized eggs and enough acidity to fight off many harmful bacteria, it’s not the silent threat many imagine.

Left at room temperature, those bacteria can multiply, even if the mayonnaise still looks and smells fine. Respecting a few simple habits—using clean utensils, refrigerating promptly, sealing the lid, and discarding questionable batches—turns mayonnaise from a suspected enemy into what it really is: a safe ingredient, protected by the care you give it.
