In China's Troubled Food, Chicken Butt, Feathers Lurk 'Guardian' rounds up some pretty disgusting ingredients By Rob Quinn, Newser Staff Posted Oct 14, 2013 3:23 AM CDT Updated Oct 14, 2013 7:28 AM CDT 27 comments Comments Feathers and fox hair? (AP Photo) (Newser) – Despite occasional attempts to crack down, food scandals in China are a persistent—and gross—problem, the Guardian finds in a round-up of the country's recent food scandals. In Jiangsu province, 16 men have been handed hefty prison sentences for making and selling "poisonous and harmful" cooking oil made from ingredients including chicken and duck anus, pig offal, feathers, and even fox hair. In Fujian province, investigators discovered that almost all of the beef jerky on sale was made from pork processed with illegal chemicals. And passengers on the national airline aren't immune: At least 30 people on an Air China flight from Xinjiang province to Beijing became ill with stomach cramps and diarrhea after being served a beef-based inflight snack. A passenger reported finding two expiration dates on the package, the more recent of which was four days before the flight. After an outcry on social media, the airline acknowledged the incident and blamed it on a packaging mix-up.
