Case overview
What this settlement is about
A new class action lawsuit takes aim at Costco over its Kirkland Signature Five Cheese Tortelloni with Parmigiano Reggiano. According to the complaint, the product's packaging claims it has 'no preservatives' — but the plaintiff points to the ingredient list, which discloses manufactured citric acid. The lawsuit alleges this ingredient actually functions as a preservative, made through industrial fermentation and chemical processing, contradicting the label's claim. No settlement has been reached yet; the case is currently proceeding as a nationwide class action.
