I didn’t have the faintest idea.

Understanding Tuna Salad Ingredients
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.
The Science Behind Food Spoilage
Food spoilage is primarily caused by the growth of bacteria, yeast, and molds. These microorganisms thrive in environments where moisture and nutrients are present, such as in tuna salad. Temperature plays a critical role in the rate of spoilage; bacteria multiply rapidly between 40°F and 140°F, known as the ‘danger zone.’ Refrigeration slows down bacterial growth, but it does not stop it entirely. Over time, ev
