When shopping for beef, make sure the meat is bright red. If there is blood pooled in the foam tray, it only means the meat has been prepared the day before. If your looking for something thats just been put out that day, look for something without blood. Now, when it comes to vacuum sealed meats, light brown is not bad! IT is the natural color of beef. It will turn red a few minutes after its been opened. On the other hand, a silvery brown is a sign of deterioration. Keep these tips in mind when shopping for beef.
