How to Check if Your Bacon is Spoiled (And How to Keep it Fresh)

Your mouth is watering at the thought of frying up that bacon in the fridge, but you can’t quite remember how long it’s been there. Days? Weeks? Months? Eating spoiled bacon is a surefire way to spoil the rest of your day, but how do you know if bacon is still good? What are the signs? Before you reach for that package, check out our simple signs that your bacon might be bad, plus our tips on how to refrigerate, freeze, and dispose of bacon.

Things You Should Know

Check the “sell by” or “use by” date on the bacon's packaging, and eat the bacon either before the “use by” date, or no longer than 7 days after the “sell by” date.
Examine the bacon for green, gray, or brown discoloration, mold spots, or slimy texture, all of which indicate spoiled bacon.
Smell your bacon and check for a sour or rotten smell–even just a hint of an unpleasant smell is a sign of bad bacon.
Store your bacon in an airtight container for up to 7 days in the fridge, or up to 4 months in the freezer. Dispose of spoiled bacon in an airtight freezer bag.

Check the expiry date on the bacon packet. Look for either a “sell by” or “use by” date, and compare the indicated with the current calendar date. Don’t eat any bacon that’s past its “use by” date. The “sell by” date is a little different: properly stored bacon can be eaten up to 7 days past its “sell by” date.^{[1]

- Note that properly frozen bacon can last far beyond its "sell by" or "use by" dates.
- Also check to make sure the packaging is still sealed and has no holes or tears, which may expose your bacon to bacteria and cause it to spoil prematurely.
Open up your bacon and give it a good whiff. Spoiled bacon will have a distinct, sour smell. If your bacon smells even a bit rotten or off, it’s best to toss it.^{[2]

Bring the bacon to a well-lit area and remove it from its packaging. Fresh, uncooked bacon is light pink and white in color, while unspoiled precooked bacon has darker red veining. If your bacon matches these descriptions, it’s safe to eat.^{[3]

Touch the bacon and check for a slimy texture. Unspoiled bacon is fairly dry or rough in texture, though it may have some condensation or juices on its surface. Spoiled bacon, on the other hand, often has a distinct slimy, viscous feel. This is because lactic acid bacteria has begun to grow and break down the bacon, lending it that unpleasant, sticky texture.^{[4]

- If the original packaging is still sealed, keep the bacon until 7 days after the indicated “sell-by” date, or until the “use-by” date.
2
Keep cooked bacon fresh in the fridge for an additional 7 days. Extend your bacon’s shelf life by cooking it before its expiration date, and then storing it in the fridge in an airtight, resealable container. In addition, wrap the bacon strips in a paper towel to absorb any excess grease that may make your bacon soggy during its stay in the fridge.
- Bacon will stay fresh for different amounts of time, depending on how it’s been prepared. Cooked bacon in strips lasts for about a week in the fridge, and up to 6 months in the freezer, while bacon bits will last for about 6 weeks in the fridge, and 6 months in the freezer.

But there’s a caveat: though you can freeze bacon and keep it food safe indefinitely, frozen bacon starts deteriorating in quality after about 4 months, so it’s recommended you use it before then.^{[6]

1
Thaw frozen bacon in the refrigerator, cold water, or in the microwave. Avoid defrosting bacon at room temperature. Instead, place frozen bacon in the fridge the night before use, or use the defrosting function on your microwave and enter the approximate weight. Alternatively, place your frozen bacon in a sealed container, and place the container in a cold water bath for a few hours.^{[7]

- Bacon is also perfectly safe to cook straight from the frozen state, if you don’t have time to thaw it.
2
Dispose of bacon that’s been above 40 °F (4 °C) for more than 2 hours. Avoid leaving your bacon out on the counter too long. Bacon exposed to the environment at room temperature may harbor unsafe bacteria. Whenever possible, keep your bacon stored in a cool, airtight space.^{[8]

How should you dispose of bacon?

You don’t want spoiled bacon sitting exposed in your kitchen garbage, rotting and stinking up the place. To properly dispose of spoiled bacon, place the bacon (along with its original packaging) in a freezer bag, and throw it away in an outdoor trash can, if possible. Otherwise, keep the bag in the freezer and throw it out on garbage pickup day.^{[9]

Refrigerate or freeze bacon fat in a sterilized jar. When you cook bacon, avoid pouring the fat down the drain, where it can congeal and clog up your pipes. Instead, strain the leftover fat into a sterilized jar, let it solidify overnight, then keep the jar in the fridge for up to 3 months, or indefinitely in the freezer. Then, use your leftover bacon fat to add flavor to other dishes, like vegetable stir fries or as a tasty substitute for shortening.^{[10]

- If you don’t care to use your leftover bacon fat, let it cool for a couple hours, then pour it into a disposable plastic container, and throw the container out.

Staphylococcus aureus is a common source of food poisoning because it isn't deterred by salty, cured meats, leading some people to a false sense of security thinking that the salt makes the food safe.
