Can I Eat Expired Mayonnaise Commercially Packaged Unopened?

Mayonnaise typically has a 'best by' date for quality purposes rather than a strict expiration date for safety. Over time, mayonnaise can separate, become watery, or develop off-flavors. While expired mayonnaise may not cause immediate harm, its quality deteriorates, affecting taste and texture. It's generally safe to consume slightly expired mayonnaise if stored correctly, but it's best to discard it if there are signs of spoilage.

To determine if commercially packaged unopened mayonnaise has gone bad, check for any visible signs of mold or discoloration. Give it a sniff to see if there is any sour or off-putting odor. Lastly, feel the texture - if it appears watery or separated, it may be best to discard it.

Mayonnaise can pose a risk of foodborne illnesses if not stored properly. The main pathogens of concern are Salmonella and Listeria. To prevent contamination, always refrigerate mayonnaise, avoid cross-contamination with raw foods, and never leave it at room temperature for extended periods, especially in hot weather. High-risk scenarios include using contaminated utensils or jars, consuming expired mayonnaise, or leaving it out in warm conditions.

For optimal storage and freshness, always refrigerate mayonnaise after opening, even if it's commercially packaged and unopened. Store it in the main part of the refrigerator, not in the door where temperatures fluctuate. Keep the lid tightly sealed to prevent air exposure and contamination. If the mayonnaise separates, stir it well to reincorporate the ingredients. Avoid using wet utensils in the jar to prevent bacterial growth.
