Summer School: Introduction to Total Diet Studies for Assessing Exposure

Sunday 7th July-Friday 12th July 2013, INSA, Portugal

Total diet studies complement traditional monitoring and surveillance providing a scientific basis for population dietary exposure to contaminants and nutrients and the potential impact on public health. Food selection is based on (national) consumption data, prepared as eaten, and data from related foods pooled prior to analysis. TDS-Exposure is focussing on exposure to food contaminants including heavy metals, mycotoxins and persistent organic pollutants (POPs, e.g. polychlorinated biphenyls), which pose a risk to human health and the environment, and estimation of chronic exposure to pesticide residues in food as well as food additives intake. However, exposure is based on whole diets, as consumed, rather than contamination of raw commodities as previously measured, resulting in a more realistic measure of exposure to potentially harmful compounds than currently available.

TDS facilitate risk assessment and health monitoring, but some EU Member States and Candidate Countries do not have TDS programmes or use a variety of methods to collect data, and it is not clear whether data are comparable. It is important to harmonise methods for dietary exposure risks worldwide, and TDS-Exposure will standardise methods for food sampling, analyses, exposure assessment calculations and modelling, priority foods, and selection of chemical contaminants. In the process, a variety of approaches and methods for sampling and analyses will be assessed, and best practice defined. Priority contaminants for TDS and foods that contribute most to total exposure in Europe will also be established.

Information about these and existing European TDS will be published to promote better handling of dietary exposure data, and establish a legacy of harmonised methods and science-based recommendations for public health worldwide. In addition, TDS-Exposure is providing training, enabling best practice in the creation and execution of TDS programmes, and ensuring data collected are coherent with others studies globally. This TDS-Exposure Summer School is the first of three introducing key aspects of TDS and contaminant analysis.

1. Programme description

The programme consists of five elements: (1) basic foundations of total diet studies (2) design and planning (3) sample preparation and analysis (4) exposure assessment and publication (5) quality management, each including aspects of theoretical and practical learning. Basic foundations of total diet studies will introduce TDS and planning as well as application of food consumption data in dietary assessment of contaminants; Design and planning will explain development of a food list, criteria for selecting chemical substances and populations of interest, sampling plans and collection of foods for TDS; Sample preparation and analysis will look at the culinary preparation of foods (as eaten) and a range of analytical issues, and how food databases are created and managed, and food information coded accurately; Exposure assessment and publication will explore data management using FoodCASE-Risk, exposure and risk assessment using MCRA, and how data should be processed and used appropriately; and Quality management will examine quality control approaches and documentation standards.

1.2 Educational objectives

The objectives of this Summer School are to introduce total diet studies, generally, and dietary exposure to contaminants, specifically: Explore the scientific and technical knowledge underpinning total diet studies for exposure assessment Provide insight into methods and approaches, and the quality of data Enable students to apply this knowledge in their expert field (e.g. public health, food technology, research).

1.3 Expected learning outcomes

a. Knowledge: account for the design and planning for total diet studies as well as their use in monitoring and surveillance in human health, particularly in respect of dietary contaminants. Describe food sampling, preparation and analysis, data collection and quality control, and identification and selection of relevant chemical substances and populations of interest. Explain the differences between data management and quality control options, and the principles underpinning each. Describe how research and healthcare messages should be formulated based on information from these studies, and maintain knowledge and access appropriate resources.

b. Skills: apply knowledge to carry out independent assessment of food and application of information from TDS/ TDS-Exposure as relevant to their field of expertise. Identify key aspects of TDS-Exposure research, comment on the potential and limitations, especially in exposure analysis. Understand the requirements for selecting foods, populations of interest and chemical contaminants. Use relevant IT-based tools to input and retrieve total diet study and exposure information, document and ensure data quality, and apply outcomes appropriately.

c. Competences: critically evaluate total diet studies information, particularly in reference to exposure to contaminants in specific populations. Demonstrate independent thinking in the application of information from total diet studies including exposure and national consumption patterns, and formulate healthcare messages based on these data. Participate effectively and with confidence in peer-group discussions developing/ applying information from total diet studies. Act autonomously in the creation, management and use of information from total diet studies including exposure assessment, and demonstrate skills relevant for future employment. Use lifelong learning skills for evaluation and critical thinking, and take responsibility for continuing professional development.

1.4 Career outcomes

The modules provide knowledge, skills and competence supporting an independent, professional role within international diet and health research, food manufacturing or aspects of healthcare.

c. Description of exercises

Criteria for selection of chemical substances and population targets (Monday, 8th July 2013 14.00-15.30)
EXERCISE: (part 3 of the lecture) will consist in an application of the prioritization tool. Depending on time, the exercise could be about the definition of the weights allocated to prioritization criteria and/or the evaluation of one or several substances regarding the prioritization tool

Systems for describing food – LanguaL/FoodEx (Wednesday, 10th July 2013 14.00-18.00)
EXERCISE: The intention is to present an overview of the LanguaL and FoodEx tools and try to code some products and discuss the outcomes. Participants are encouraged to bring a few food labels (actual or printed label information) for a range of products from their own country, which they can try to code, either individually or in groups, and see what interesting problems arise. The value of the exercise is in getting an idea of what is involved and the difficulties. The systems are very comprehensive and complex so it will just be a snapshot with (hopefully) some interesting discussion but not necessarily all the answers!

Communication @ Public Health: share, involve and improve! (Wednesday 10th July 2013 20.00-21.30)
EXERCISE: We transfer facts, ideas, emotions, knowledge, attitudes and skills through communication. The aim of this informal session is to show the importance of communication to increase knowledge and awareness of a health issue, problem and its solutions.

Exposure assessment at the international level (Thursday 11th July 2013 11.00-12.30)
EXERCISE: Students will learn how to upload TDS data to the MCRA software and how to perform an exposure assessment with different input data.

Quality Management Principles and Practices suited to TDS (Friday, 11th July 2013 09.00-12.30)
