Though you might not enjoy the taste, texture, or smell of yogurt that’s past its expiration date, it is unlikely to cause harm. Expiration dates are conservative to ensure food safety.
It’s important to note that expiration dates apply to unopened products. Once a yogurt has been opened, it should be eaten within a week or two. After that time, it is more likely to spoil and can cause gastrointestinal issues.
So, if you’re wondering if you can eat yogurt that’s expired, the answer is probably yes. However, it’s best to use your judgment and discard any yogurt that looks or smells bad.
