PBB

This week, we’ve told you about efforts to clean up the old Velsicol Chemical plant. There’s a threat to the local drinking water supply after the first attempt to clean up the plant failed. Birds still die from DDT, decades after the plant stopped producing it.

But we haven't told you who's paying to fix it.


Velsicol Chemical operated on the banks of the Pine River in St. Louis, Michigan from 1938 to 1978. It was the site of the infamous PBB mixup. The entire plant was buried in place and now it's leaking.

There are a lot of former industrial sites in Michigan that need to be cleaned up, but the Velsicol Superfund sites in St. Louis, Michigan are unusual in their size and in the amount of nasty chemicals lurking in the ground where people live, work and play.

The company tried to contain the pollution before, but its solution didn’t work. Ask some of the community members about that original plan and they say they could have told you it wasn’t going to work.

About 10 years ago, a weird chemical started showing up in the drinking water in St. Louis, Michigan.

It was a byproduct of DDT. The insecticide is now banned in the U.S., but DDT was manufactured in St. Louis for 20 years.

Now, the city is working to get a new source of drinking water.

It's been over 40 years since the Michigan Chemical Corporation/Velsicol made a catastrophic mistake that affected millions of Michigan residents.

The company from St. Louis, Michigan, shipped a toxic flame retardant chemical to the Farm Bureau Service instead of a nutritional supplement. That chemical was PBB or polybrominated biphenyl.

PBB was mixed into livestock feed, but it took a year to discover the accident. Millions of consumers ate contaminated milk, meat, and eggs during this time.

Jane-Ann Nyerges was one of the farming families whose lives were changed after the PBB contamination.

All this week we're bringing you stories about the chemical company responsible for the PBB tragedy in Michigan. Michigan Chemical accidentally contaminated the state’s food supply in the 1970s, but the legacy of that company is still very much with us today.

Michigan Chemical – which later became Velsicol Chemical – made more than just PBB, and it left these toxic chemicals behind in St. Louis, Michigan.

More than 40 years ago, Michigan’s food supply was contaminated. People’s health is being affected, even now.

All this week, we’re looking at the ripple effects left behind by the company that made that tragic mistake.

In 1973, the Michigan Chemical Corporation shipped a toxic flame retardant chemical to a livestock feed plant instead of a nutritional supplement. The chemical is called polybrominated biphenyl, or PBB. It took about a year to discover the accident.

More than 40 years ago, people in Michigan were poisoned. Researchers are still following those people today.

In 1973, a fire-retardant chemical called PBB, polybrominated biphenyl, accidentally got mixed into livestock feed.  It took a year to discover the accident. 

Studies estimate 70-90% of people in Michigan had some exposure to PBB from eating contaminated milk, meat and eggs. The MDCH says the "overwhelming majority of those who were exposed to PBB received very low levels."

Other people had higher levels of exposure.

Researchers at Emory University in Atlanta are studying the long-term health effects of exposure to PBB. The team was in Michigan this past weekend to continue the study.

Forty years ago a chemical mix-up led to one of Michigan’s worst environmental tragedies, and it’s not over yet.

The mix-up occurred in early 1973 at the former Michigan Chemical Corporation plant (which later became the Velsicol Chemical Corporation) in St. Louis, Mich. The company accidentally shipped flame-retardant chemicals to livestock farms around the state.

Farmers thought they were getting a feed supplement. Instead, they were dosing their animals with the toxic chemical PBB.

The problem wasn’t discovered for another year -- and the chemicals were passed up the food chain to humans.
