In 2007, in Vancouver, Canada, Max Ipinza got a scare when he bit into his Big Xtra burger and tasted not meat, but peppermint. Immediately realizing that there was chewing gum in what remained of his burger, he spit it out and, by now feeling very sick, went to the hospital to get checked out, worried about the risk of contracting hepatitis. He believes someone intentionally put the gum into his food. McDonald’s Canada said the company had begun an in-depth investigation into Ipinza’s complaint with the co-operation of health officials. Ipinza said he would henceforth be bringing his own packed lunches to work.
