The Nanny star, who is a cancer survivor, admits she was stunned to learn that U.S. mums have more flame retardants in their breast milk than any other women on the planet.
She raised the issue during an appearance on Washington, D.C. radio programme The Tommy Show on Monday (24Sep12), and told listeners that some breast milk contains retardants that are stuffed into upholstery.
Drescher explained, "This is something that is not really talked about and yet we're all wondering why all these kids suddenly have all these learning disabilities and attention deficit and autism and there has not been a connection made.
"We're kinda selling these women that breast milk is the second coming (but) do any of these women check for high levels of heavy metals or chemicals? I don't think so."
Drescher is encouraging nursing women to undergo a three-day test which ensures they aren't passing metals to their children, adding, "The doctors can give you a kit to take home."
