What is the shelf life of blue cheese dressing?

• A. 120 days
• B. 180 days
• C. 60 days
• D. 90 days

Answer: (A)

The main idea being tested is how long a dairy‑based dressing like blue cheese dressing stays safe and maintains quality when stored properly. For unopened blue cheese dressing kept refrigerated, a common, practical shelf life used in food‑service practice is about four months, or 120 days. This window reflects the balance between preserving flavor, texture, and safety given the dairy and fat content, as long as the product stays cold and unopened.

So 120 days is considered the best fit because it aligns with typical guidelines for this type of dressing under proper refrigeration. Shorter durations (60 or 90 days) would cut the window too much and risk using product that’s past its peak quality, while a much longer duration (180 days) could exceed safe limits for dairy‑based dressings even when unopened.

If the dressing has been opened, the usable period is much shorter, and always follow the label’s directions for opened products.
