Is it good to eat an 100 year old egg?

It is not recommended to consume century/hundred-year-old eggs or pidan that are significantly older than the suggested period. The extended aging process can potentially lead to the accumulation of harmful bacteria or other microorganisms that may pose a risk to your health.

To ensure food safety, it is advisable to adhere to the recommended consumption period for century eggs, which is typically around several weeks to a few months after preparation. If you have concerns or are unsure about the age or safety of a century egg, it is best to discard it to avoid any potential health issues.
