These advances will be discussed, how they may identify individuals with genetic defects, how they may lead to cures for these defects and how the future of society may be changed. These are typical examples of real life situations that must be investigated by the field office laboratories of the Food and Drug Administration. The analytical methods used to solve mysteries such as these must be highly reliable. Speed is also essential, because the laboratory findings often dictate the immediate and final course of action taken by the FDA to protest the public.

Many carcinogens are capable of causing gene mutations.
In certain genes, these mutations can cause the deregulation of gene products which normally are under strict control in cells. In addition, mutations can inactivate gene products which serve to control cell growth. It is believed that for a cancer cell to form, a number of genes must be altered in the normal cell making the development of cancer a multistep process. This multistep nature or cancer will be discussed as it relates to the interplay between the various cells. Topics will include the occurrence of microbes in newly emerging diseases, in contamination of hamburger meat, as well as in the cleaning up of our environment.
