Ground meat turns gray due to a process called oxidation. When meat is exposed to air, the myoglobin in the meat reacts with oxygen, causing it to turn from a bright red color to a grayish-brown color. This process is natural and does not necessarily mean the meat is spoiled. However, if the meat has a strong odor or slimy texture, it may be a sign that it has gone bad and should be discarded. **

Furthermore, the demand for beef is often higher than for pork and chicken, which can also drive up the price. Finally, the processing and distribution of beef may also contribute to its higher cost compared to pork and chicken. **
