Ditto. And look for bubbles or dried bits of food on the sides of the jar or near the lid.Farmfresh said:Just be sure the jar is kept dry and has no rust on the lid. When you open the can make sure the seal was tight and you get a good pop as air goes in. Then check the contents by smelling. It should smell like what it is (chicken smells like chicken etc..) Finally be sure to heat the meat or broth for at least 20 minutes at a boil before using to be double sure of safety.
