Shrimp. In 2012, ABC News reported how shrimp in China and other Asian countries imported to the United States are farmed in cramped and unsanitary conditions. To avoid illness, farmers use antibiotics and chemicals to ensure the shrimp survive. ABC News sent 30 samples of shrimp bought in 30 different grocery stores across the country to the Institute of Environmental and Human Health food lab at Texas Tech University. What they found was antibiotics banned in the United States; enrofloxacin, chloramphenicol, and carcinogen nitrofuranzone.
