I didn’t have the faintest idea.

Tuna salad is a popular and convenient dish that many people enjoy for its taste and nutritional benefits. However, its shelf life can be a point of contention, especially when prepared in large quantities. My sister often makes a huge bowl of tuna salad and keeps it in the fridge for up to a week. While she enjoys it throughout the week, I find myself hesitant to eat it after the third day. This raises an important question: how long is tuna salad actually safe to consume when stored in the refrigerator? Understanding the factors that affect its shelf life can help us make informed decisions about food safety.

Tuna salad typically consists of canned tuna, mayonnaise, and various other ingredients such as celery, onions, and spices. Each of these components has its own shelf life and storage requirements. Canned tuna, once opened, should be consumed within a few days. Mayonnaise, being an emulsion of eggs and oil, is prone to spoilage if not stored properly. Fresh vegetables like celery and onions can also degrade over time, affecting the overall quality of the salad. The combination of these ingredients creates a dish that is both nutritious and perishable.
