Big Pharma gets rich when you get sick. Pfizer, the largest pharmaceutical corporation in the U.S., plead guilty in 2009 to the largest health care fraud in U.S. history, receiving the largest criminal penalty ever for illegally marketing four of its drugs. It was Pfizer’s fourth such case. As if Pfizer’s massive use of animal experimentation wasn’t heart wrenching enough, Pfizer decided to use Nigerian children as guinea pigs. In 1996, Pfizer traveled to Kano, Nigeria to try out an experimental antibiotic on third-world diseases such as measles, cholera, and bacterial meningitis. They gave trovafloxacin to approximately 200 children. Dozens of them died in the experiment, while many others developed mental and physical deformities. According to the EPA, Pfizer can also proudly claim to be among the top ten companies in America causing the most air pollution.
