Learn how to check if unopened milk is bad by inspecting the expiration date, smell, container swelling, and consistency.
Video transcript
To tell if unopened milk is bad, check the expiration date first. If it's past, smell the milk through the container—sour odor is a clear sign. Look for swelling or bloating in the container, indicating gas production from bacterial activity. Shaking the milk can reveal lumps or an unusual consistency. Always discard if you notice these signs.
