How Long Does Pork Fat Last in the Fridge?

Pork fat is a versatile and flavorful cooking ingredient. From raw fatback to rendered lard pork fat adds richness texture and delicious flavor to many dishes. However, like all fats, pork fat can go rancid if not stored properly. So how long does pork fat last in the fridge? Here is a complete guide to maximizing the shelf life of different types of pork fat.

Overview of Pork Fat Types

There are a few main varieties of pork fat

• Raw Fatback – This is the thick, unrendered layer of fat directly under the skin of the pig. It has a short shelf life.

• Lard – Lard is pork fat that has been rendered and clarified. It lasts much longer than raw fat.

• Bacon Grease – The rendered fat leftover from cooking bacon. Its shelf life is similar to lard.

• Salted Pork Fat – Cured pork fat options like salt pork. Lasts longer due to curing.

Each type has different storage methods and shelf lives.

Shelf Life of Raw Fatback

Of all pork fat varieties, raw fatback has the shortest fridge life. According to sources like The Spruce Eats, raw fatback will last:

• 3-7 days in the fridge
• 2-4 weeks in the freezer

Chef’s Resources claims fatback lasts around 3 days refrigerated, while some butchers say up to 1 week if vacuum sealed.

The wide range means refrigerated shelf life depends on preparation method and freshness when purchased. If the fatback is already a few days old before you buy it, expect a shorter fridge life of 3-5 days.

For maximum freshness, store fatback wrapped in plastic to protect it from air exposure. Freezing can extend the shelf life significantly.

How Long Does Lard Last in the Fridge?

Properly stored lard has a much longer shelf life than raw fatback. According to Eat By Date and Food Safety News, lard can last:

• 6-8 months in the refrigerator
• 1-2 years in the freezer

The key is keeping lard in an airtight container in the fridge. Exposure to air can make it spoil faster. Some sources claim refrigerated lard lasts up to a year before going rancid.

Freezing lard extends the shelf life even longer – up to 2-3 years when stored in airtight packaging.

Bacon Grease Refrigerator Life

Bacon grease is the rendered pork fat leftover after cooking bacon. It has a similar storage life to lard:

• 2-3 months in the refrigerator
• 4-6 months in the freezer

Keeping bacon grease covered in the fridge prevents it from absorbing odors and flavors that can cause faster spoilage. For extended freezer storage, grease should be strained and frozen in an airtight container.

Cured Pork Fat Shelf Life

Cured pork fats like salt pork, fatback and salt-cured bacon last longer than fresh varieties due to the preserving effects of salt. Refrigerated, cured pork fat will last:

• 2-4 weeks in the fridge
• 6 months in freezer

The high salt content allows the fat to stay fresher longer when stored properly. Keep cured fat wrapped tightly or in a sealed container.

Signs Pork Fat Has Gone Bad

Watch for these signs that indicate pork fat has spoiled and should be discarded:

• Rancid, unpleasant smell
• Changed texture – slimy or sticky
• Discolored fat – gray, brown or yellow
• Mold growth
• Bitter, off taste when cooked

Trust your senses – rancid pork fat will make itself known through foul odors, visible mold and unappetizing textures or flavors. When in doubt, throw it out.

Storing Pork Fat for Maximum Freshness

Follow these tips to extend the shelf life of pork fat:

• Refrigerate or freeze immediately after rendering or purchasing.

• Keep raw fatback wrapped in plastic wrap or butcher paper.

• Store lard and bacon grease in airtight containers.

• Freeze lard in blocks by pouring into molds before freezing.

• Vacuum seal pork fat blocks for extended freezer shelf life.

• Monitor fridge life closely and watch for signs of spoilage.

Proper, air-tight storage is key to preventing rancidity and extending the usability of your pork fat.
