Book Description
A chronological review of the history of significant research contributing to the development of current bacteriological criteria and standards for shellfish waters is described beginning with Prescott, Winslow, and Eijkman in 1904 and culminating in a proposal for a fecal coliform standard in 1974. Coliform and fecal coliform standards are defined, and the significance of the presence of these organisms in shellfish waters is discussed. The National Shellfish Sanitation Program presumes that both coliform and fecal coliform standards represent equivalent degrees of pollution and resultant health hazard when measuring levels of diluted sewage related to point sources of pollution in shellfish growing area waters. These two indicator groups are used in conjunction with sanitary surveys for the classification of shellfish growing areas and interpreted according to the limitations of the groups.

Book Description
The abundant shellfish populations of the rich brackish waters of the coastal areas have been an important source of food from prehistoric times. Productive shellfish-harvesting waters have been decreasing at an alarming rate in recent times. Currently, of the fifteen million acres of national estuarine waters available for shellfish harvesting, only 64% are classified as approved and the amount of acreage available is decreasing annUally. The remaining areas are classified as prohibited, conditionally approved or restricted. Despite the growing problems, the shellfish industry is of vital importance to the economy of many coastal areas. The safety of molluscan shellfish has been brought into question. The executive summary of the National Academy of Sciences, Institute of Medicine's Report on Seafood Safety, states that "available data from CDC and the Northeast Technical Services Unit (NETSU) of the Food and Drug Administration for 1978-87, as well as literature reports, suggest that the greatest number of seafood associated illnesses are from raw molluscan shellfish harvested in waters contami nated with raw or poorly treated human sewage. The majority of these illnesses have unknown etiologies suggestive of Norwalk or Norwalk-like agents that cause human viral gastroenteritis". In addition, there have been numerous reports on safety problems of raw molluscan shellfish. The safety of raw molluscan shellfish is determined by using environmental indicators of fecal pollution. With respect to shellfish, the indicator concept evolved early this century.
