Can you used mayonnaise after experation date?

It is not generally recommended to use mayonnaise after its expiration date. Mayonnaise is a perishable food product made with eggs, oil, and vinegar, and it can become contaminated with harmful bacteria over time. Consuming mayonnaise that has passed its expiration date can lead to foodborne illness, which can cause symptoms like vomiting, diarrhea, abdominal pain, and fever.

The expiration date on a mayonnaise jar is a safety guideline set by the manufacturer based on the product's expected shelf life. After this date, the mayonnaise may start to deteriorate in quality and may not taste or smell as good. It may also become more susceptible to bacterial growth, increasing the risk of foodborne illness.

To ensure food safety, it is a good practice to discard mayonnaise after its expiration date. If you are unsure whether mayonnaise is still safe to use, it is best to err on the side of caution and throw it out.
