How long does salad dressing keep after date?

It's difficult to give an exact time frame for how long salad dressing keeps after the date on the bottle. Here's why:

* Type of dressing: Some dressings (like oil and vinegar) are naturally more shelf-stable than creamy dressings with dairy or eggs.

* Storage conditions: Refrigeration is key for most salad dressings. Warm temperatures or exposure to sunlight can shorten their lifespan.

* Opening date: Once opened, most dressings have a shorter shelf life.

General Guidelines:

* Refrigerated, Unopened: Most dressings will be safe to eat for several months past the "best by" date if kept refrigerated and unopened.

* Refrigerated, Opened: Opened dressings can last for 1-2 months in the refrigerator, but it's always a good idea to check for any off-odors or changes in texture.

Signs of Spoiled Salad Dressing:

* Off-odor: A sour, rancid, or fermented smell.

* Changes in texture: Separation, thickening, or a watery consistency.

* Mold growth: Visible spots or patches on the surface or inside the dressing.

Best Practices:

* Check the date: Always look for the "best by" date and try to use the dressing before that.

* Refrigerate properly: Keep dressings in the refrigerator, especially after opening.

* Use within 1-2 months after opening: It's a good rule of thumb to toss opened dressings after this time.

* Taste test: Always taste a small amount before consuming to ensure it still tastes fresh and safe.

If you're unsure about the quality of a dressing, it's always best to err on the side of caution and discard it.
