Anybody look on a container of decaf coffee lately? One of the ingredients used in the process, is Methlylene Chloride. See web info below As with all decaffeination processes, the direct method begins with soaking green unroasted beans. The beans are then flushed with methylene chloride (DCM), a solvent that is generally used in direct contact with the beans. As the DCM soaks through all parts of the bean, the caffeine is drawn out. The U.S. Food and Drug Administration (FDA) considers the DCM residual levels in this decaffeination process low enough to be acceptable. The FDA, however, and the National Cancer Institute have both linked DCM to cancer in laboratory animals. In 1989 the FDA banned DCM for use in cosmetics and hair sprays. Who says, not easy to get. No decaf for me. Bill Kasprzak Moog Inc. > -----Original Message----- > From: Larry J.
