Can yogurt be consumed three days past its refrigerated expiration date?

Yogurt is generally not safe to consume if it has been expired for three days, even when refrigerated.

Yogurt is a fermented dairy product typically made from milk. It contains abundant vitamins, beneficial probiotics, and calcium, effectively supplying essential nutrients the body needs. However, once yogurt expires, the activity of its probiotics decreases, and harmful bacteria may multiply rapidly. Consuming such yogurt can easily lead to gastrointestinal discomfort, including abdominal pain and diarrhea. Therefore, yogurt that has been expired for three days—even when kept refrigerated—should not be consumed.

In addition, other foods past their expiration date are also not recommended for consumption, to avoid potential adverse effects on health.
