Bologna is a popular meat product that is commonly used in sandwiches and as a snack. It is made from finely ground meat, typically beef, chicken, or pork, and is blended with various spices, seasonings, and additives. While bologna can be a tasty and convenient food, it can also pose health risks if it is consumed after it has gone bad.

In this article, we will discuss the signs that bologna is bad, how to properly store it, and answer some frequently asked questions.

How Long Does Bologna Last

The shelf life of bologna depends on several factors, including whether it is unopened, opened, or sliced. Here are some general guidelines:

1. Unopened Bologna

Unopened bologna, which is still in its original packaging, can last for a certain period if stored correctly.

Factors affecting shelf life:

  • Packaging: The airtight and sealed packaging of unopened bologna helps preserve its freshness and quality.
  • Storage temperature: Keeping the bologna in the refrigerator is crucial. A consistent temperature between 34°F to 40°F (1°C to 4°C) slows down bacterial growth and extends the shelf life.

Typical shelf life: Unopened bologna usually remains safe to eat for about 1 to 2 weeks beyond the “sell-by” or “use-by” date mentioned on the package.

Quality considerations: Although the bologna may still be safe to consume within this timeframe, its taste and texture might deteriorate over time. For the best quality, it’s advisable to consume it before the indicated date.

2. Opened Bologna

Once the package of bologna is opened, its shelf life significantly reduces, and specific precautions should be taken to ensure safety.

Factors affecting shelf life:

  • Exposure to air: When exposed to air, the bologna becomes susceptible to bacterial contamination and spoilage.
  • Refrigeration: Always store opened bologna in the refrigerator to slow down bacterial growth.

Typical shelf life: After opening, bologna should be consumed within 3 to 5 days to ensure its safety and quality.

Safety considerations: It’s essential to inspect the bologna for any signs of spoilage before consuming it. If you notice an off smell, sliminess, unusual texture, or mold, discard the product immediately to prevent foodborne illnesses.

3. Sliced Bologna

Sliced bologna, particularly those purchased from deli counters, has a shorter shelf life compared to unopened or whole bologna.

Factors affecting shelf life:

  • Exposure and handling: Sliced bologna has more surface area exposed to air, which accelerates spoilage.
  • Temperature control: Proper refrigeration is crucial to slow down bacterial growth and maintain the safety of sliced bologna.

Typical shelf life: Sliced bologna should be consumed within 3 to 5 days after purchase to ensure its safety and quality.

Safety considerations: Deli-sliced bologna may have a higher risk of contamination due to the handling process. Make sure to handle and store it carefully to minimize the risk of bacterial growth.

Always follow the storage guidelines and expiration date provided on the bologna packaging. If you have any doubts about the safety or quality of the product, it’s best to err on the side of caution and discard it. Proper storage and handling are essential to enjoying bologna safely and deliciously.

Signs that Bologna is Bad

How To Tell If Bologna Is Bad

Bologna is a type of processed meat that can spoil just like any other food. If you’re unsure about the freshness of your bologna, be sure to check for the following signs:

Off Smell

When bologna is spoiled, it undergoes a process of bacterial or mold growth, causing the breakdown of proteins and fats. This results in the release of volatile compounds that produce a foul or off-putting odor. Trust your sense of smell – if the bologna emits a sour, putrid, or generally unpleasant smell, it’s a clear indication that it has spoiled.

Change in color

One of the most obvious signs that bologna has gone bad is a change in color. Fresh bologna should be a pink or reddish color. However, if the color has changed to gray or greenish, it’s a sign that the bologna is no longer fresh.

Foul odor

Bologna that has gone bad will emit a strong and unpleasant odor. If it smells sour, rancid, or otherwise off-putting, it is likely spoiled. If you’re unsure about the smell, it’s better to err on the side of caution and discard the bologna.

Slimy texture

Bologna that has been stored improperly or for too long will develop a slimy texture. This sliminess is caused by bacterial or mold growth, which produces a sticky film on the meat. This sliminess is a clear indication that the meat has gone bad and should be discarded immediately. Fresh bologna should have a firm texture, so if it feels slimy or sticky to the touch, it is best to avoid consuming it.

Unusual Appearance

Visual cues are essential in determining the freshness of bologna. Inspect the surface of the bologna for any signs of mold growth, discoloration, or dark spots. Mold is a common indicator of spoilage and can appear as fuzzy or discolored patches on the meat. Any unusual or suspicious appearance is a sign that the bologna may be unsafe to eat.

Presence of mold

Mold growth on bologna is a sign that it has gone bad and should not be consumed. Mold can be dangerous if ingested and can cause serious health problems, including allergic reactions and respiratory issues. If you notice any mold on your bologna, discard it immediately.

Expiration date

Another important indicator of bologna freshness is the expiration date. Always check the expiration date on the package before consuming bologna. If the expiration date has passed, it’s better to err on the side of caution and discard the product.

Excessive Moisture

Excess moisture inside the packaging of bologna is a sign of deterioration. Bacteria and other microorganisms thrive in moist environments, leading to the spoilage of the meat. When you observe liquid pooling inside the package, it is best to discard the bologna.

Sour Taste

When bologna goes bad, it can develop a sour or unpleasant taste. This is due to the production of various compounds during spoilage. If the bologna tastes sour or has an off flavor, it is an indicator that it is no longer safe to consume.

By keeping an eye out for these signs of spoilage, you can ensure that your bologna is always fresh and safe to eat. If you’re ever unsure about the freshness of your bologna, it’s better to discard it and avoid any potential health risks.

How to Properly Store Bologna?

how to properly store bologna

Proper storage is crucial for ensuring that your bologna stays fresh and safe to eat. Follow these tips to keep your bologna fresh for as long as possible:

1. Refrigerate promptly

Once you purchase bologna from the store, it’s crucial to refrigerate it as soon as possible after you return home. Bologna is a perishable product and contains meat, so leaving it at room temperature for extended periods can lead to rapid bacterial growth, increasing the risk of spoilage and potential foodborne illnesses. Prompt refrigeration slows down the growth of harmful bacteria, ensuring the bologna stays safe to eat for a longer period.

2. Store in the refrigerator

Bologna should be stored in the refrigerator, preferably at a temperature below 40°F (4°C). At this temperature, the growth of bacteria and other pathogens is significantly reduced. A refrigerator with a built-in thermometer can help you monitor and maintain the proper temperature. If the fridge is too warm, it can accelerate the spoilage process and reduce the shelf life of the bologna.

3. Follow the “use-by” or “best-by” date

When purchasing bologna, always check the packaging for a “use-by” or “best-by” date. These dates indicate the period during which the manufacturer guarantees the product’s quality and safety if stored properly. Consuming the bologna before this date ensures you enjoy it at its best, with minimal risk of spoilage or off-flavors.

4. Keep it airtight

Once you open a package of bologna or slice it for use, it’s essential to keep it airtight. Exposure to air can cause the bologna to dry out and lose its flavor and texture quickly. Place the sliced bologna in an airtight container or resealable plastic bag and remove as much air as possible before sealing. This prevents the entry of external contaminants and helps maintain the desired moisture level within the packaging.

5. Separate from raw meats

To prevent cross-contamination and the potential spread of harmful bacteria, store bologna separately from raw meats in the refrigerator. Raw meats can carry pathogens that could transfer to other foods, including bologna. Use separate containers or plastic bags to store bologna and raw meats, ensuring there is no contact between them.

6. Avoid storing in the door

Though it might seem convenient, the refrigerator door is the warmest part of the fridge and experiences temperature fluctuations every time you open it. Storing bologna in the main part of the fridge, away from the door, helps maintain a more consistent and cooler temperature, extending the bologna’s shelf life and keeping it safer to eat.

7. Use a deli drawer or meat compartment

If your refrigerator has a dedicated deli drawer or meat compartment, it’s an ideal place to store bologna. These compartments are designed to maintain a slightly lower temperature than the main refrigerator area, which helps preserve the quality and freshness of deli meats, including bologna.

8. Freezing bologna

If you have an unopened package of bologna and don’t plan to consume it before the expiration date, freezing is an option for longer storage. Freezing bologna suspends bacterial activity and helps maintain the product’s quality for an extended period. Before freezing, ensure the package is airtight, and consider double wrapping it with freezer-safe materials to prevent freezer burn.

9. Storage duration

Bologna should be consumed within three to five days of opening the package. If left unopened, it can last up to two weeks in the refrigerator. If you plan on freezing bologna, it should be used within two months of freezing.

10. Thawing frozen bologna

When you want to use frozen bologna, it’s best to thaw it in the refrigerator overnight. Slow thawing in the refrigerator helps retain the quality and texture of the bologna while minimizing the risk of bacterial growth. Avoid thawing bologna at room temperature or using hot water, as these methods can lead to uneven thawing and promote the growth of harmful bacteria.

Frequently Asked Questions (FAQs)

Can you eat bologna after the expiration date?

No, it is not safe to eat bologna that has passed its expiration date. The expiration date is a good indicator of when the bologna is no longer safe to eat.

How long does bologna last in the fridge?

If properly stored in the refrigerator, unopened bologna can last for up to two weeks. Once the package is opened, the bologna should be consumed within three to five days to avoid any spoilage or bacterial growth.

Can you eat bologna that has a white film on it?

If the white film on the bologna is a result of the product being vacuum-sealed, it is safe to eat. However, if the white film appears to be mold, it is best to discard the bologna.

Can you get sick from eating bad bologna?

Yes, eating spoiled bologna can cause food poisoning and may result in symptoms such as vomiting, nausea, diarrhea, and abdominal pain. In severe cases, it can lead to dehydration and other complications.

How to safely dispose of bad bologna?

If you suspect that your bologna has gone bad, it is important to discard it properly to prevent any contamination or illness. Wrap the bologna in plastic wrap or a plastic bag before disposing of it in the trash. This will prevent any bacteria or mold from spreading to other food items.


In summary, bologna can be a delicious and convenient food, but it is important to know when it has gone bad to avoid any potential health risks. Be sure to check for any signs of spoilage, store it properly in the refrigerator or freezer, and always check the expiration date before consuming. By following these guidelines, you can enjoy bologna safely and without any concerns.
