Mayonnaise is safer than many people assume, but it is not as forgiving as a busy kitchen might suggest. Commercial mayonnaise is generally made with pasteurized eggs and acidic ingredients that help slow the growth of harmful bacteria, but those protections don’t replace proper handling. Every time the jar sits on a warm counter or a utensil covered in crumbs goes back into it, the risk can increase.
The problem is that spoiled or contaminated mayonnaise may not always give you an obvious warning before it causes illness. That’s why simple habits matter.
Take out only the amount you need and return the jar to the refrigerator promptly. Always use a clean utensil, keep the container tightly closed, and follow the storage instructions on the label. Homemade mayonnaise deserves extra caution because recipes and preparation methods can vary; when in doubt about its freshness or safety, it’s better to discard it.
These habits may seem small, but they can make a real difference. You’re not just protecting a condiment—you’re helping protect everyone who sits down at your table.
