Mayonnaise is a staple condiment in many households, adding a rich and creamy texture to various dishes. However, have you ever stopped to think about the safety of that jar of mayonnaise that’s been sitting in your fridge for months? Can outdated mayonnaise make you sick? In this article, we’ll delve into the world of mayonnaise and explore the risks associated with consuming expired or spoiled mayonnaise.
Understanding Mayonnaise and Its Shelf Life
Mayonnaise is a mixture of oil, egg yolks, vinegar or lemon juice, and seasonings. The acidity in mayonnaise, typically from vinegar or lemon juice, acts as a natural preservative, helping to prevent the growth of bacteria and other microorganisms. However, this acidity is not foolproof, and mayonnaise can still spoil if not stored properly or if it’s past its expiration date.
The shelf life of mayonnaise depends on various factors, including the storage conditions, packaging, and ingredients used. Generally, unopened mayonnaise can last for several months to a year when stored in the refrigerator at a temperature of 40°F (4°C) or below. Once opened, mayonnaise typically lasts for 6-9 months in the fridge.
Signs of Spoilage
So, how can you tell if your mayonnaise has gone bad? Here are some signs to look out for:
- Off smell: If your mayonnaise has a strong, unpleasant odor, it’s likely spoiled.
- Slime or mold: Check for any visible signs of slime or mold on the surface or in the jar.
- Slimy texture: If the mayonnaise has a slimy or watery texture, it’s probably gone bad.
- Rancid taste: If the mayonnaise tastes sour or rancid, it’s time to discard it.
The Risks of Consuming Outdated Mayonnaise
Consuming outdated mayonnaise can pose several health risks, including:
Food Poisoning
The most significant risk associated with consuming outdated mayonnaise is food poisoning. Mayonnaise can be contaminated with bacteria like Salmonella, E. coli, and Listeria, which can cause food poisoning. Symptoms of food poisoning include:
- Nausea and vomiting
- Diarrhea or abdominal cramps
- Fever
- Headache
In severe cases, food poisoning can lead to life-threatening complications, especially in vulnerable individuals like the elderly, pregnant women, and people with weakened immune systems.
Allergic Reactions
Some people may be allergic to eggs or other ingredients in mayonnaise. Consuming outdated mayonnaise can trigger an allergic reaction, which can range from mild symptoms like hives and itching to life-threatening anaphylaxis.
Other Health Risks
In addition to food poisoning and allergic reactions, consuming outdated mayonnaise can also lead to other health issues, including:
- Gastrointestinal problems: Consuming spoiled mayonnaise can cause stomach upset, diarrhea, and other gastrointestinal problems.
- Infections: In rare cases, consuming contaminated mayonnaise can lead to infections like botulism or listeriosis.
Preventing Mayonnaise Spoilage
To minimize the risk of mayonnaise spoilage, follow these tips:
Store Mayonnaise Properly
- Store mayonnaise in the refrigerator at a temperature of 40°F (4°C) or below.
- Keep the jar tightly sealed to prevent contamination.
- Avoid storing mayonnaise in direct sunlight or near heat sources.
Check Expiration Dates
- Always check the expiration date on the jar before consuming mayonnaise.

Use Clean Utensils
- Always use clean utensils when handling mayonnaise to prevent cross-contamination.
- Avoid dipping utensils into the jar multiple times, as this can introduce bacteria into the mayonnaise.
Conclusion
While mayonnaise is a delicious and versatile condiment, it’s essential to handle it safely to avoid foodborne illnesses. By understanding the shelf life of mayonnaise, recognizing signs of spoilage, and following proper storage and handling techniques, you can minimize the risk of getting sick from outdated mayonnaise.

What happens if I eat expired mayonnaise?
Eating expired mayonnaise can potentially make you sick, but the severity of the symptoms depends on various factors, such as the storage conditions, handling, and personal tolerance. If the mayonnaise has been stored properly in the refrigerator at a temperature of 40°F (4°C) or below, the risk of foodborne illness is lower.
However, if the mayonnaise has been left at room temperature for an extended period or has been contaminated with bacteria, viruses, or mold, the risk of food poisoning increases. Symptoms of food poisoning from expired mayonnaise can range from mild to severe and may include nausea, vomiting, diarrhea, stomach cramps, and fever.
How long does mayonnaise last after the expiration date?
The shelf life of mayonnaise after the expiration date depends on several factors, including the storage conditions, packaging, and handling. Generally, mayonnaise can last for several months after the expiration date if stored properly in the refrigerator. However, it’s essential to check the mayonnaise for visible signs of spoilage, such as mold, sliminess, or an off smell, before consuming it.
If you notice any of these signs, it’s best to err on the side of caution and discard the mayonnaise. Even if the mayonnaise looks and smells fine, its quality and safety may degrade over time. If you’re unsure whether the mayonnaise is still safe to eat, it’s better to be safe than sorry and discard it.
Can I still use mayonnaise after the “Best By” date?
The “Best By” date on mayonnaise indicates the manufacturer’s recommended date for optimal quality and flavor. While mayonnaise may still be safe to eat after this date, its quality and texture may degrade over time. If you store mayonnaise properly in the refrigerator, it can last for several months after the “Best By” date.
However, if you notice any changes in the mayonnaise’s appearance, smell, or texture, it’s best to discard it. Even if the mayonnaise looks and smells fine, its quality may not be the same as when it was freshly opened. If you’re unsure whether the mayonnaise is still safe to eat, it’s better to err on the side of caution and discard it.
What are the symptoms of food poisoning from mayonnaise?
The symptoms of food poisoning from mayonnaise can range from mild to severe and may include nausea, vomiting, diarrhea, stomach cramps, and fever. In severe cases, food poisoning can lead to dehydration, electrolyte imbalance, and even life-threatening complications.
If you experience any of these symptoms after consuming mayonnaise, it’s essential to seek medical attention immediately. Food poisoning can be treated with rest, hydration, and medication, but in severe cases, hospitalization may be necessary. If you suspect that you have food poisoning from mayonnaise, it’s crucial to report it to the relevant authorities to prevent others from getting sick.
How can I store mayonnaise to extend its shelf life?
To extend the shelf life of mayonnaise, it’s essential to store it properly in the refrigerator at a temperature of 40°F (4°C) or below. Make sure to keep the mayonnaise away from direct sunlight, heat sources, and moisture. Always check the mayonnaise for visible signs of spoilage before consuming it.
When storing mayonnaise, make sure to keep the jar tightly sealed and away from strong-smelling foods, as mayonnaise can absorb odors easily. If you don’t plan to use the mayonnaise within a few months, consider freezing it. Freezing mayonnaise can help extend its shelf life, but it’s essential to follow proper freezing and thawing procedures to maintain its quality and safety.
Can I freeze mayonnaise to extend its shelf life?
