I bought a carton of yogurt but forgot it in the refrigerator. When I took it out later, I noticed it had expired—I’m not sure whether it’s still safe to drink. Doctor, how long after its expiration date is yogurt no longer safe to consume?

Hello, from the perspective of food hygiene, yogurt past its expiration date contains abundant pathogenic microorganisms. Consuming expired yogurt may introduce these pathogens into your body, potentially causing mild symptoms such as abdominal pain, bloating, and diarrhea; in more severe cases, it may lead to serious infectious diseases that endanger your health. We hope this information is helpful to you. Wishing you a pleasant and healthy life!
