There are a few ways to tell if ground beef has gone bad:
- Look at the ground beef. If it’s dull brown or greyish in color, it’s probably not safe to use and should be discarded.
- Smell the ground beef. If you get a sour or rotten smell when you take a sniff of it, it’s not safe and should not be used. Remember: Always cook your beef thoroughly to destroy any potentially harmful bacteria. See this guide for information on proper and safe temperatures.
- Touch the ground beef. If the ground beef feels slimy or sticky, it’s probably bad. Normal ground beef that hasn’t expired will break apart in your hands but shouldn’t have a sticky or slimy texture.
