If you open the package and are met with an unpleasant smell, that’s a sign the meat is beginning to spoil. Fresh ground beef shouldn’t have a noticeable smell, so any off-smelling odors are a cause for concern. When in doubt, it’s best to err on the side of caution, especially if the meat is displaying another indication of spoilage.

Texture

Fresh ground beef should have a relatively firm consistency, and when squeezed, it should naturally break apart. If the ground beef has a slimy or sticky texture, it means it’s going bad. As the USDA explains, a sticky texture could indicate the presence of spoilage bacteria. Ground beef with these textures should not be consumed and should be thrown away.

Conclusion

If the ground beef is gray on the exterior or has another indicator of spoilage, it’s best to discard it. But if your ground beef looks, smells and feels OK, then you’re set to use it.
