Trader Joe’s Black Truffle Flavored Extra Virgin Olive Oil
May 2017: A class-action lawsuit was filed against Trader Joe’s for allegedly falsely advertising its Black Truffle Flavored Extra Virgin Olive Oil as being flavored with black truffles when, according to plaintiffs, it is flavored with a synthetic and chemical ingredient (specifically, a perfume called 2,4-dithiapentane or formaldehyde dimethyl mercaptal). (Plaintiffs filed an amended complaint in September 2017.) (Brumfield et al v. Trader Joe’s Company, Case No. 17-cv-3239, S. D. NY.)
