Iconic foods have been a part of our culture for so long that multiple generations are able to recognize brands decades old. Spam is an example of a pantry staple that is consumed in both lean and rich times.

Preppers and survivalists include Spam into their food supplies as a shelf stable, long-lasting source of protein that can be eaten raw or cooked.

Some people have cracked open and eaten a can of Spam long past its due date with no ill effects. We know a sealed can of Spam can last up to 5 years on the shelf, but how long does it last when opened?

Spam should last at least 7-10 days with refrigeration, though according to the manufacturer, Spam should be eaten within 2-3 days after being open (fridge or no fridge).

Now, you might have jumped to the conclusion that Spam might be unhealthy for you due to the preservatives in it, which is fair.

Although, you should probably keep reading to learn a little bit more about this product and how it might not be so bad for you after all.

What is Spam?

Spam is synonymous with meat in a can. It is as recognizable as corned beef or deviled ham. Preppers call it the ultimate survival food while campers call it a delicacy over the fire.

However, you view spam is part of the collective picture the blue can has implanted in our minds.

Health nuts may call Spam a chemical nightmare; others say it’s not even real meat.

You’d be surprised to learn that it’s actually just meat in a can that’s been preserved really well. It’s the process that gives it the manufactured look and texture, but in the end it is just meat.

What Ingredients Are In Spam?

There are few ingredients inside a can of Spam with the majority of them used in traditional methods of preserving meat. The ingredients according to the manufacturer are:

• Pork
• Ham
• Salt
• Sugar
• Water
• Potato Starch
• Sodium Nitrite

The important ingredients to watch are salt and sodium nitrite. Both are great preservatives for long-term storage. They could have just used salt on its own but the sodium nitrite preserves the texture and taste.

Sodium nitrite prevents the fats from oxidizing which stops the bacteria from getting into the meat and spoiling it.

This pretty much makes it never have an expiry date. You don’t want to wait too long before eating it because the taste and texture are going to change the more it ages.

Afterwards the can is vacuum sealed and cooked off so that there is no chance of any bacteria causing issues with the product.

This combination of ingredients and manufacturing processes is what ensures the long shelf-life of Spam.

How Long is Spam Good For After Opening?

You can expect to get at least a week out of a can of opened Spam. This will be based on where you store the can.

The refrigerator will be the best place to put it since it will take longer for bacteria to start to grow.

If you are going to leave it out on the counter then you’ll want to consume it within a day as the meat will start to spoil quicker.

A lot of campers will take Spam on their fall and winter trips since the opened can will hold longer if they can’t eat it right away.

How Long is it Good For Unopened?

An unopened can of Spam can last up to 5 years on the shelf. There is a best before date that the manufacturer recommends you eat the food by.

The salt and sodium nitrite alone would be enough to preserve the meat for an extended period of time.

Add in the cooking and vacuum sealing processes and you have a rock solid survival food for your pantry.

What Does Spoiled Spam Look Like?

Old Spam is still fine to eat, however, spoiled spam can cause serious health problems if it is consumed. Spam that has gone bad when you start to smell a rotting smell from the can.

Safety Precautions When Eating Spam

As with all canned products, any kind of malformation on the can may break the seal and allow bacteria to start breeding inside the can.
