This was a story that began a year and a half before I ever wrote the first word. It was first brought to my attention in July 2011 that Michigan had a toxic history. Nearly 40 years ago, due to human error, cattle feed had been mixed with a flame retardant chemical called PBB.
In 1973, nearly every Michigan resident was exposed to a toxic chemical. As I brought this story out of the shadows and examined the lasting health effects, I had an advantage: the story was heavily archived and documented.
In 1973, it was discovered that Michigan Chemical had accidentally used the flame retardant chemical PBB instead of a vitamin additive for cattle feed.
