Why Does Cryovac Pork Smell Bad?

Cryovac pork smells bad when it defrosts because it is scented with chemicals.

The stink originates in the ingredients used to create the aroma. Raspberry-scented pork is an example of something that smells great when made as an edible product but awful when made as a decorative arrangement.

So, why does cryovac pork smell bad? While it’s great that cryovac pork is safe to eat, it smells bad!

While it may not be dangerous, it can be unpleasant to smell. Since the pork is shrink-wrapped in plastic, it has nowhere to go.

The smell eventually makes its way through the plastic, and it’s enough to cover an entire room. This smell also comes from the pork’s natural juices and fats, which leak out during the freezing process.

While the cryovac method does make shipping cheaper, this smell is one reason people prefer fresh pork to frozen pork.

How Long Does Cryovac Pork Usually Last?

Overall, the shelf life of frozen pork is generally proportional to the shelf life of fresh pork.

If you simply defrost the pig and cook it, you’ll be fine as long as the meat stays at 40 degrees Fahrenheit or lower.

If it becomes warm, bacteria will find its way into the meat and break down the proteins into amino acids and sugars that create ammonia gas, which smells bad.

So, while it doesn’t require refrigeration, you should store your frozen hog as soon as possible or put it in the refrigerator immediately after purchase.

How Long Does Cryovac Pork Last in the Refrigerator?

Cryovac Pork will stay in the fridge for up to a week from the date of packaging as long as it is properly wrapped and stored appropriately.

If the packaging is kept intact and the meat is still cold enough, it can last much longer before it begins to rot or lose flavor.

Storage Time Exceeds Prescribed Limit

Even though Cryovac is compact and easy to carry with you, once thawed and opened at home, the meat needs to be refrigerated within two hours.

If you keep your pork in a plastic bag for longer than that and then place it in the refrigerator, the aromas that escape will permeate your fridge and make it stink.

This deterioration in meat quality is more pronounced when temperatures are high.

As a result, it is essential that you transfer your pig from the plastic bag into a tightly sealed container immediately once it has been opened, or you will risk compromising its quality and taste.

The Presence of the Androstenone Gene in Meat

Some pig species naturally produce an odorous chemical called androgens during their lifetime.

Unfortunately, some of these odors can be released into the air when the meat thaws.

This gene is similar to the gene that produces aroma in beef but has a different effect on a pig’s skin tissue.

When the meat thaws, the gene makes it smell bad, but it doesn’t change how good the meat is overall.

Pork generated from male pigs that carry the Androgen gene releases more of this chemical than female pigs that do not carry it.

Inadequate Cryovac Meat Storage

To keep the freshness of the meat, it must stay below 40 degrees Fahrenheit at all times after thawing.

If this situation is not maintained, there is a high likelihood of the meat going bad due to bacterial contamination.

And, when the pig begins to rot, it releases a pungent smell that makes the entire room stink.

The Package Has Tiny Air Holes

There is a chance that the plastic bag that holds your pork has tiny air holes that can let oxygen in and allow bacteria to grow.

It might occur by chance if the bag was poorly manufactured. However, this also exposes the meat to spoilage more quickly than usual.

Because of these small flaws, air and bacteria are able to get through the packaging and into the pork itself.

This could lead to big problems with smell once the package is opened and the air inside is contaminated.

Pork Meat Nearing Expiration

As previously noted, fresh pork has a shelf life of around four to five days.

If you leave it out at room temperature, there is a high likelihood that it will spoil within a few days and lose most of its flavor.

If you pack this rotting meat, the smell it gives off may be so bad that you have to throw it away before you can eat it.

So, it’s very important to buy your pork from a butcher with a good reputation for selling high-quality meats and who sells their meats in packages that keep air out.

Poor Pork Meat Quality

It’s likely that the original pig was sick and given antibiotics at some point during its life or right before it was killed.

The meat’s quality may consequently be compromised, and it may emit an unpleasant odor when you cook it.

For instance, the animal may have had a parasite in its intestines that made it hard for it to digest.

If and when this occurs, the same faults that lead to the rotten smell occur when the pig is slaughtered.

How to Keep Cryovac Pork From Turning Bad

Fumigate the Storage Areas and Your Refrigerator.

As a last resort, try fumigating your refrigerator with ammonia to get rid of any smells that may have built up over time because of food particles and other organic matter.

This technique will assist you in killing all the germs present in the refrigerator and removing the smell of ammonia from the interior surfaces, including the fridge door seal.

If you can do this before putting your meat away, you greatly reduce the chance that it will go bad or give off a strong smell when you cook it.

Maintain the Proper Temperature and Storage Duration

Obviously, you should learn to cook the meat as soon as you bring it home from the store so that the smelly gases from the rotting flesh don’t get into the air inside your fridge.

I’ve previously said that the pork may stay fresh for around four to five days if you store it properly in the fridge.

The same is true for the freezer. However, you should only freeze your pork for a maximum of two months before throwing it out.

Strengthen the Cryovac Packaging

As was already said, if there are small problems with how the meat is packaged, it may start to smell bad as it ages in the freezer.

So, it’s important to check the package before putting it in the freezer to make sure that the packaging material is still whole and hasn’t been damaged before it was sealed with a vacuum seal machine.

This makes it impossible for oxygen from the outside to get into the package through tiny holes made in the material by rough handling or using too much force when sealing.

Before Storing the Pork, Thoroughly Wash and Dry It.

By thoroughly cleaning and drying the pig before you freeze it, you remove most of the surface bacteria (including the E. coli).

Make sure to remove any blood spots present on the meat as well by wiping them off with a clean cloth after washing them thoroughly with water and a disinfectant solution.

Before Storing the Pork Meat, Inspect It.

The hog should be checked for the first time right after it is bought to make sure it has not been exposed to any diseases or parasites during its life.

Before storing the Cryovac pork in your refrigerator, make sure that you check for signs of spoilage such as mold or discoloration of the meat, as well as the presence of rodent droppings.

Check that it seems fresh and free of maggots or insects as well before you store it in the appliance.

To thoroughly check the package, open it up and remove some of the inner contents of the cryovac bag in order to inspect the contents inside for any visible contamination, leakages, or tears in the material.
