To preserve foods safely, it is critical that you maintain low temperatures. You can significantly reduce the growth of microorganisms at temperatures of 40°F (4°C) or below. Freezing at 0°F (-17°C) does not kill microorganisms, but stops them from growing. For long-term storage, always freeze perishable foods that have been vacuum packaged.
It is important to note that vacuum packaging is not a substitute for canning and it cannot reverse the deterioration of foods. It can only slow down the changes in quality. It is difficult to predict how long foods will retain their top-quality flavor, appearance or texture because it depends on age and condition of the food on the day it was vacuumed packaged.
IMPORTANT:Vacuum packaging is NOT a substitute for refrigeration or freezing. Any perishable foods that require refrigeration must still be refrigerated or frozen after vacuum packaging.
