Can I Eat Expired Mayonnaise?
No, it's generally not recommended to eat mayonnaise past its expiration date. While some sources suggest a short grace period, particularly for unopened jars, the risk of foodborne illness increases significantly after the "best by" date.
Mayonnaise, due to its high fat content and acidic nature, is susceptible to bacterial growth. After the expiration date, the likelihood of harmful bacteria multiplying increases dramatically, potentially leading to food poisoning. Symptoms can range from mild upset stomach to severe illness.
-
Spoilage: Expired mayonnaise may exhibit off-putting changes in smell, taste, and texture, indicating spoilage. A vinegary odor is a common sign. Even if the mayonnaise doesn't appear spoiled, unseen bacteria could still be present.
-
Foodborne Illness: Consuming spoiled mayonnaise can cause various illnesses, including nausea, vomiting, diarrhea, and stomach cramps. The severity depends on the type and amount of bacteria ingested.
Safe Handling and Disposal of Mayonnaise
-
Unopened Jars: Discard unopened jars a week after the "best by" date.
-
Opened Jars: Refrigerate opened jars and discard them within one month of the "best by" date.
-
Smell and Appearance: Always check the smell and appearance before consuming. If there's any unusual odor or change in texture, discard it immediately.
-
Err on the Side of Caution: When in doubt, throw it out! Foodborne illnesses can be unpleasant and potentially serious.
Several sources confirm that consuming expired mayonnaise carries risks. While some anecdotal evidence suggests people have survived eating significantly expired mayonnaise, this doesn't negate the potential dangers. The consensus among experts and food safety guidelines strongly advises against it.
