Despite rigorous preparations by the organizers in Beijing, some athletes have concerns over the food that will be available to them. Some teams are going as far as brining their own chef to the Olympics.

After spending years of training for the Olympics, a bout of food poisoning could destroy their Olympic dreams.

There’s also the worry that tainted food could lead to a positive drug test. A caterer working for the USOC told the New York Times of finding a half chicken breast measuring 14 inches while shopping in a Chinese supermarket that could have fed a family of eight.

“We had it tested and it was so full of steroids that we never could have given it to athletes,” Frank Puleo told the Times. “They all would have tested positive.”
