Does unopened salad dressing with egg whites poppyseed go bad unrefrigerated?

Yes, unopened salad dressing with egg whites and poppyseed will go bad unrefrigerated. Here's why:

* Egg whites: Egg whites are a prime breeding ground for bacteria, especially at room temperature.

* Other ingredients: The other ingredients in the dressing, such as oil, vinegar, and spices, can also spoil or become rancid over time in warm conditions.

* Safety: The risk of bacterial growth in unrefrigerated egg-containing products is high, potentially leading to foodborne illness.

It's crucial to always store salad dressing with egg whites in the refrigerator to keep it safe and fresh.

Here are some additional tips:

* Check the "Best By" or "Use By" date: Even if unopened, salad dressing has a shelf life. Pay attention to these dates.

* Refrigerate after opening: Once opened, salad dressing should be refrigerated and consumed within a few weeks.

For your health and safety, it's best to follow these guidelines.
