Sinopsis:

Unless a food is grossly contaminated, consumers are unable to detect through sight or smell the presence of  low levels of toxic chemicals in their foods.  Furthermore, the toxic effects of exposure to low levels of chemicals are often manifested slowly, sometimes for decades, as in the case of cancer or organ failure. As a result, safeguarding food from such hazards requires the constant monitoring of the food supply using sophisticated laboratory analysis. While the food industry bears the primary responsibility for assuring the safety of its products, the overall protection of people’s diets from chemical hazards must be considered one of the most important public health functions of any government. Unfortunately, many countries do not have sufficient capability and capacity to monitor the exposure of their populations to many potentially toxic chemicals that could be present in food and drinking water. Without such monitoring, public health authorities in many countries are not able to identify and respond to problems posed by toxic chemicals, which may harm their population and undermine consumer confidence  in the safety of the food supply. From a trade perspective, those countries that cannot demonstrate that the food they produce is free of potentially hazardous chemicals will be greatly disadvantaged or even subject to sanctions in the international marketplace.

 

The goal of a total diet study (TDS) is to provide basic information on the levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typical for a country before they are analyzed in order to better represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, mercury, arsenic, cadmium, PCBs, dioxins), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxin, patulin, other mycotoxins) by determining whether dietary exposure to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency and the US Food and Drug Administration  recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investment and study.

 

Total Diet Studies introduces the TDS concept to a wider audience and presents the various steps in the planning and implementation of a TDS. It illustrates how TDSs are being used to protect public health from chemicals in the food supply in many developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.

From the Back Cover:

Total Diet Studies is intended to introduce the total diet study (TDS) concept to those involved in assuring the safety of the food supply from chemical risks (e.g., government agencies and the food industry) as well as to a wider audience of interested parties (e.g., development agencies and consumer organizations). It presents the various steps in the planning and implementation of a TDS and illustrates how TDSs are being used to protect public health from the potential risks posed by chemicals in the food supply in both developed and developing countries. The book also examines some of the applications of TDSs to specific chemicals, including contaminants and nutrients.

The goal of a TDS is to provide baseline information on levels and trends of exposure to chemicals in foods as consumed by the population. In other words, foods are processed and prepared as typically consumed before they are analyzed in order to best represent actual dietary intakes. Total diet studies have been used to assess the safe use of agricultural chemicals (e.g., pesticides, antibiotics), food additives (e.g., preservatives, sweetening agents), environmental contaminants (e.g., lead, arsenic, cadmium, radionuclides), processing contaminants (e.g., acrylamide, polycyclic aromatic hydrocarbons, chloropropanols), and natural contaminants (e.g., aflatoxins) by determining whether dietary exposures to these chemicals are within acceptable limits. Total diet studies can also be applied to certain nutrients where the goal is to assure intakes are not only below safe upper limits, but also above levels deemed necessary to maintain good health. International and national organizations, such as the World Health Organization, the European Food Safety Agency, and the US Food and Drug Administration recognize the TDS approach as one of the most cost-effective means of protecting consumers from chemicals in food, for providing essential information for managing food safety, including food standards, and for setting priorities for further investigation and intervention.

About the Editors

Gerald G. Moy: For over twenty years, Dr. Moy served as a staff scientist with the World Health Organization and was primarily responsible for the exposure assessment of chemical hazards in food, including coordination of total diet studies at the international level.  Although retired, he remains active as a food safety adviser for various national and international organizations.

Richard W. Vannoort: A senior scientist with the Institute of Environmental Science & Research Ltd (ESR), Dr. Vannoort has been the scientific project leader of the last five New Zealand Total Diet Studies. He is an internationally recognized expert on TDSs and has been a technical adviser to many countries, including numerous international and regional TDS training courses sponsored by the World Health Organization.
