Short Answer: If you accidentally eat expired mayonnaise, you may have stomach upset or food poisoning, depending on how spoiled the mayonnaise is and how much you eat.
Mayonnaise is a thick, cold, and creamy sauce commonly used on sandwiches, salads, and fries.
It is made of oil, egg yolk, and an acid, such as vinegar or lemon juice, and often has other flavorings and preservatives added to it.
If you accidentally eat expired mayonnaise, you may experience nausea, vomiting, diarrhea, or stomach ache, depending on how spoiled the mayonnaise is and how much you consume.
However, the risk of food poisoning from expired mayonnaise is low, unless it shows signs of spoilage, such as mold, separation, or sour smell.
This is because mayonnaise contains egg yolk, which can harbor harmful bacteria, such as Salmonella, if not pasteurized or refrigerated properly.
Egg yolk can also go rancid over time, affecting the taste and quality of the mayonnaise.
Commercially-prepared mayonnaise is usually sterilized and has preservatives that extend its shelf life, but homemade mayonnaise is more perishable and should be consumed within a few days.
Egg yolk can provide protein, healthy fats, and vitamins, but it can also raise cholesterol levels and cause allergic reactions in some people.
Therefore, it is important to consume mayonnaise in moderation and check the expiration date and quality before eating it.
It is quite uncommon to eat expired mayonnaise, as most people tend to use it up before it goes bad or discard it when it reaches its expiration date.
However, some people may not notice the expiration date or the signs of spoilage, especially if the mayonnaise is stored in a squeeze tube or a container with a tight lid.
You can prevent or treat the symptoms of eating expired mayonnaise by drinking plenty of fluids, taking over-the-counter medications, such as antacids or anti-diarrheals, and resting until you feel better.
If the symptoms are severe or persist for more than 24 hours, you should seek medical attention, as you may have a bacterial infection that requires antibiotics.
To avoid accidental eating of expired mayonnaise, you should always store it in the refrigerator after opening, keep track of the expiration date, and inspect the mayonnaise for any changes in smell, texture, or color before using it.
You should also avoid cross-contamination by using clean utensils and not double-dipping.
If you make your own mayonnaise, you should use pasteurized eggs and consume it within four days.
