Meat needs to be tightly wrapped to minimize exposure to air. Styrofoam grocery store packaging is fine to store in the refrigerator, but if you're going to freeze, consider opening and wrapping it more tightly in plastic wrap or freezer paper, then sealing it in a Ziploc bag.
It’s recommended to freeze meat while it is still fresh. The less time meat is frozen, the better it will retain its quality and integrity. But you can store meat in the freezer for up to a year.
Gentle thawing is the best way to avoid compromising the quality of the meat. The most ideal is to plan one day ahead and move the meat from your freezer to your refrigerator or to thaw the meat in a bowl of cold water. Avoid thawing your meat in the microwave as this may impact the texture and quality of the meat.
