Will marinating beef stew meat help keep it from going bad?

Marinating beef stew meat can enhance its flavor and tenderness, but it doesn't prevent spoilage. Proper refrigeration is crucial to keep the meat safe from bacteria, and marinating should be done within a few hours to a couple of days, depending on the marinade. Always store marinated meat in the refrigerator and consume it within a safe timeframe to avoid foodborne illness.
