The photo shown below for Costco's Galette Cookies - TAG ON THE GO - Oatmeal (ITM./ART. 323050) <UPC:0-55598-00191-5> clearly says "0 g trans fat per 50 g serving".
Yet, the Nutrition Facts label shows "+ Trans / Trans 0.1 g" on the outside package, and "+ Trans / Trans 0.4 g" on the inside package. This is mathematically impossible (0 g = 0.1 g = 0.4 g), so I consider it false advertisement.
I promptly reported the problem of false advertisement to Costco Wholesale Canada Ltd., and a representative from the manufacturer telephoned to give explanations.
