Does Your Ground Beef Smell Sour? Here’s Why And What To Do

Ground beef is a versatile and delicious ingredient that can be used in a variety of dishes. However, it’s important to be aware of the signs of spoilage to ensure you’re consuming safe meat. One of the most common indicators of spoilage is an off odor, but what does it mean when ground beef smells sour?

What Causes Ground Beef to Smell Sour?

Sour ground beef is typically caused by the growth of lactic acid bacteria (LAB). These bacteria are commonly found on the surface of meat and can multiply rapidly under certain conditions, such as when the meat is not properly refrigerated. As LAB grow, they produce lactic acid, which gives the meat a sour smell and taste.
