Tuna Pasta Salad

Normally, the commercially packed tuna pasta salad would have a shelf-life of about 2-3 days in the refrigerator when stored below 40 degrees F, check the 'Use By' date for reference. However, once opened, it should be eaten within 3 hours if left out at room temperature, or within 1-2 days if refrigerated right after opening. A homemade tuna pasta salad also has a refrigerated shelf life of about 3-4 days. As for freezing, it's not generally recommended, since the mayonnaise or other creamy dressings in the salad might separate when thawed, causing a change in texture and taste.

There are a few signs to look out for if you're unsure whether your tuna pasta salad has gone bad. First, check for any strange or off-putting smell. If your salad smells sour, fishy or just not right, better to throw it out. Taste can be another indication; if it tastes bitter or off, don't eat it. Visually, if you notice any change in color or appearance - such as if your salad has turned darker or developed mold - it's a clear sign it's no longer safe to eat.

• Always store your tuna pasta salad in the refrigerator, ideally at a temperature below 40 degrees F. • Store leftovers in an airtight container, which helps preserve its freshness. • If you won't be eating your salad immediately, refrain from adding the dressing until you're ready to eat; this can help prevent the pasta from becoming soggy. • Avoid keeping the salad at room temperature for more than 2 hours, as this can speed up bacterial growth and spoilage. • Consider preparing your salad without mayonnaise or a similar creamy dressing if you anticipate needing a longer shelf-life. Using an oil-based dressing can increase the salad's longevity.
