For example, signs and placards displayed in Panera’s retail outlets contain statements such as “Food should be clean. No artificial colors, preservatives, sweeteners, flavors, or anything else you wouldn’t want to serve your family.” And bags include statements like “100% clean food: No artificial flavors, sweeteners, preservatives/No colors from artificial sources.”

The national chain is attempting to jump on the clean-eating bandwagon but misrepresents its products (including sandwiches, baked goods and other prepared foods) in the process, Tabler alleged, as they contain the same synthetic biocide residue found in Monsanto’s Roundup weed killer.

“There is a growing desire among consumers to purchase and consume ‘clean’ foods, which consumers understand to be foods free of artificial ingredients, especially pesticides,” according to the complaint. “Panera is deceiving consumers into believing that [its] products are of a higher quality, free from synthetic chemicals, or free from chemical residues from the production process when they are not.”

Tabler purchased a whole-grain bagel on multiple occasions from Panera stores, relying on the “clean” and “100% clean” representations, she told the court.

The putative class action alleges violations of the state’s Unfair Competition Law, False Advertising Law and Consumer Legal Remedies Act, seeking monetary damages as well as a halt to the allegedly deceptive advertising.

Why it matters: The challenge to Panera’s “eat clean” and “100% clean” claims brings to mind the continuing class actions over “all natural” advertising claims, which have targeted everything from chips and dip to sunscreen.
