A retired medical supply manufacturer who considers bisphenol A to be perfectly safe" gave $5 million to the research center headed by the chairman of a Food and Drug Administration panel about to rule on the chemical's safety. The July donation from Charles Gelman is nearly 50 times the annual budget of the University of Michigan Risk Science Center, where Martin Philbert is founder and co-director. Philbert did not disclose the donation to the FDA, and agency officials learned of it when reporters asked about it. Gelman said he considers the chemical, which is used to make baby bottles and aluminum can liners, to be safe. He said he had made his views clear to Philbert in several conversations. Philbert denied that. Philbert's committee is expected to release its opinion this month. The decision of Philbert's committee is expected to have huge implications on the regulation and sale of the chemical in items such as baby bottles, reusable food containers and plastic wraps. Since the late 1990s, studies have linked bisphenol A to cancer, heart disease, obesity, reproductive failures and hyperactivity in laboratory animals. Gelman, a retired manufacturer of syringes and medical filtration devices, has fought against government regulation of pollutants for years. He is an anti-regulation activist and an outspoken supporter of organizations such as JunkScience.com, the Cato Institute and the Competitive Enterprise Institute that attack the credibility of government and academic scientists on such topics as global warming and hazardous chemicals.
