Maybe you should do some research when you work at a company where you’ll need to be able to answer customer’s questions.
In 1997, the Vegetarian Resource Group exposed the fact that McDonald’s was secretly spraying their uncooked fries with a beef-based spray so that when they were cooked in “100% vegetable oil” they would still taste like they’d been fried in lard.
This information was then quoted in Eric Schlosser’s “Fast Food Nation”, making the general public more aware of this issue. Also, there was a lawsuit brought by two Hindus and one non-Hindu vegetarian about it (emphasizing the religious issue as well as the lack of truth in advertising, etc).
Because they got caught, they stopped doing it in the last few years (as far as anyone has been able to tell).
