PBB Health concerns? How do I contact the Michigan PBB Registry: The Registry is a partnership between the Pine River Superfund Citizen Task Force and the PBB Citizens Advisory Board, the Mid-Michigan District Health Department, Alma College, Central Michigan University, and Emory University. 

In the 1970’s, the Michigan Chemical Company made two products at the same plant: polybrominated biphenyl (PBB), a fire-retardant chemical used in the manufacture of electrical appliances, and magnesium oxide, a nutritional supplement for livestock feed. In 1973, the company shipped PBB instead of the nutritional supplement to feed mills. The PBB was mixed into livestock feed and consumed by cattle, pigs, and chickens. Contaminated milk, beef, and other farm products were sold throughout the state until the mix-up was discovered about a year later. People across the state of Michigan were exposed to PBB by eating contaminated food. This includes children born years later who may have been exposed in the womb and through breastfeeding. 

To study the possible long-term health effects related to PBB exposure, Michigan residents joined The Michigan PBB Registry established in 1976 by the Michigan Department of Community Health (MDCH). In 2011, MDCH was no longer able to maintain the registry and transferred it to Emory University and is under the direction of Michele Marcus, Ph.D. All original study participants and their children and grandchildren are considered to be members of the registry. Individuals who want to stay in the PBB registry must provide consent to transfer their PBB records from MDCH to Emory University. By transferring your health records to Emory University, you will receive up-to-date information on study findings and will have opportunities to guide future research priorities. To transfer your records, go to the PBB Registry website ( and complete the on-line Consent to Transfer Records Form.

Funding for this research has been provided by the National Institute of Environmental Health Sciences, the Centers for Disease Control and Prevention, and the US Environmental Protection Agency.
