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."
