The National Advertising Division (NAD) has ruled that Mizkan America, Inc. provided a reasonable basis for its advertising claim that “consumers prefer the taste of Ragú Homestyle Traditional over Prego Traditional.” The Campbell Soup Co., which makes Prego, challenged the ad on the grounds that Mizkan’s consumer survey methodology was flawed. Both parties conducted a taste test of the products; the Mizkan test reportedly showed a consumer preference for Ragú while the Campbell test showed no preference. The Mizkan test included testing of all tomato-based sauces, while Campbell limited its test to traditional-style sauces. NAD found the Campbell test “overly restrictive” and that its results were not “stronger or more persuasive” than those of Mizkan.
