The Physicians Committee for Responsible Medicine has a message
for all the people going to Superbowl parties today:
More than 1.23 billion chicken wings will be devoured as football fans watch the San Francisco 49ers take on the Baltimore Ravens in the Super Bowl... Just five wings have more calories, fat, and cholesterol than a Big Mac. Sickening, but more nauseating: Most chicken products people eat are tainted with feces.
They go into more detail
A typical large processing plant may slaughter more than a million birds per week. There, chickens are stunned, killed, bled, and sent through scalding tanks, which help remove feathers but also act as reservoirs that transfer feces from one carcass to another. After scalding, feathers and intestines are mechanically removed. Intestinal contents can spill onto machinery and contaminate the muscles and organs of the chicken and those processed afterward.
