You can freeze salt pork to extend the life of the salt pork and prevent spoilage.
Salt pork can be kept out of the refrigerator at room temperature for up to 2 weeks but if you plan to keep the salt pork longer than 2 weeks the salt pork needs refrigeration.
Refrigerating salt pork makes the salt pork last for up to 3 months.
If you freeze the salt pork you extend the life of the salt pork to 6 months.
Frozen salt pork lasts for up to 6 months before it goes bad.
Salt pork does eventually go bad so you need to use it up within 6 months of freezing it.
It used to be back in the old days that salt pork was cured really good that it would last without any refrigerator and could be taken on very long journeys without the risk of spoilage.
But salt pork made today is not as rigid and cannot last long without refrigeration.
