So What’s Bacon?

​As you probably know, bacon is a side pork. It’s a cured meat from the side or back of the pig. It is the smoked bacon that people usually use to cook at home.


The fat in bacon provides its flavor and texture when cooked. Not only it allows the bacon become more flavorful but also makes it more crispy and tender.

There are 2 different types of bacon: wet curing and dry curing. Firstly, in order to make dry-cured bacon, they tend to rub a mixture of salt and sugar, which works slowly through the meat. As the result, the bacon tends to be drier, reduces moisture and gives the high intensity of flavors.

In contrary, the wet-cured bacon is soaked in special liquid brine (a mixture of salt and water solution) for roughly 2 days before 2 weeks of maturing. This results in a pretty salty flavor, more subtle and distinctively meaty texture in the bacon.

Does Bacon Go Bad? If So, How Long Does Bacon Last?


Without a doubt, bacon has a shelf life and there is no denying to that. Depending on numerous factors such as packaging, storage condition, kinds of cured bacon, the shelf life of bacon tend to vary.

Firstly, an unopened package usually lasts up to 1 – 2 weeks beyond the printed date if it is stored perfectly with proper packaging. You can safely freeze the bacon up to 6 – 8 months. Practicing proper preservation techniques will definitely help you prevent food poisoning.

The freshly opened bacon, however, only lasts 1 week in the fridge after it pasts the “sell by” date with proper packaging and storage condition. Last but certainly not least, the cooked bacon can be safely consumed for 7 – 10 days.

Although, this shelf life information is reliable, there are various factors that can affect your bacon. Please consider our advice as an opinion and eat responsibly.

What Does Use By Date On Bacon Pack Mean


When shopping in grocery store, you probably notice the expiration date (or use by date) printed on the packages.

The date indicates that customers should eat the products within this period of time. Otherwise, the food will go expired and might be bad to consume.

There isn’t “use by date” or “expiration date” on the pork’s meat, so instead, you want to look for the “sell by date” printed on the packages whenever you buy fresh bacon from the store.

Due to its differences, you might safely use the bacon even after its sell by date has lapsed.

How to ​Know if Bacon Has Gone Bad?

It’s very important as it can get you food poisoning. So if you have just a tiny little doubt about how weird it smells, don’t risk eating it at all. It isn’t that worthy of your health.

The other method is to observe those slices of bacon. Fresh and good bacon tends to have bright and pinkish color with pale-yellow fat. If the bacon has green dots or sheen around the meat, then it’s probably bad to use.

You can also feel the bacon to decide whether it’s good to use. Fresh bacon is usually not slimy to touch. If it feels slimy, the bacon has gone bad to use. Make sure to throw it out.
