3 Dietary Exposure Assessment Food Consumption Data Food consumption data is an essential element to conduct dietary exposure assessments: Dietary Exposure = Food Consumption Data x Level of Hazard

6 Exposure Assessment in ASEAN In ASEAN, some countries regularly perform dietary exposure assessments to guide standards setting (e.g. food additives, contaminants, etc.) For chemicals, exposure estimates are compared with health reference values (ADIs, TDIs) set by JECFA to determine if consumption is within safe levels Risk Characterization = EDI / ADI If EDI > ADI = not acceptable (action taken) If EDI < ADI = acceptable (no action taken)

7 Reference: FAO/WHO, EHC 240 Chapter 6 Dietary Exposure Assessment of Chemicals in Food

8 Background ASEAN Project on Food Consumption Data Recognition among food safety authorities in ASEAN of the need to have reliable food consumption data to perform accurate exposure assessments However, existing food consumption data in ASEAN mostly collected for nutrition purposes and not available to risk assessors to do exposure assessments

9 Background ASEAN Project on Food Consumption Data ASEAN Expert Group on Food Safety (AEGFS) Project on Strengthening ASEAN Risk Assessment Capacities: Food Consumption Data proposed in 2010 Technical assistance requested to FAO and ILSI ILSI provided support to the Project through the Platform for International Partnerships (PIP) (at the time, known as the International Organizations Committee or IOC) FAO, WHO and local Malaysian consultants provided technical assistance for Phase 1 of the project ( )

10 Project Phase 1 Survey was conducted among food safety and nutrition agencies within ASEAN to find out: - Which countries have national food consumption data? - At what levels are they collected? (individual vs household) - For which population age groups? (children, adults, etc.) - What is the primary method used for data collection? (FFQ vs 24-hr recall)

11 National Food Consumption Data Individual FCD Household FCD No FCD

12 National Food Consumption Data Adults & Children Adults only

13 National Food Consumption Data 24-hr recall Semi-quantitative FFQ

14 Project Phase 1 ILSI Southeast Asia Region, FAO and Food Safety & Quality Division, Ministry of Health, Malaysia (Project lead country) jointly organized 1 st Workshop on ASEAN Food Consumption Data and Exposure Assessment October 10-13, 2011, Kuala Lumpur, Malaysia Objectives: - Discuss availability of food consumption data in ASEAN - Discuss food consumption survey methods - Identify steps to enable existing food consumption data to be used for dietary exposure assessment purposes among ASEAN countries

15 1 st Workshop Outcomes Work completed and agreements gained at the 1 st Workshop: - ASEAN countries agreed to share food consumption data to be used for dietary exposure assessment purposes - ASEAN countries agreed to compile existing food consumption data will be compiled into a common ASEAN Food Consumption Database - A draft list of harmonized food categories was developed as the basis for a common template to compile the national food consumption data - List of food categories to be further discussed via electronic working group - ASEAN countries would consider future work to harmonize food consumption data collection and reporting within their countries

16 Project Phase 2 Electronic working group was set up to discuss food categories following the 1 st Workshop (led by Malaysia) However, it was felt that a 2 nd workshop was need to finalize the list of food categories and other aspects (e.g. age groups, reported percentiles, etc.) Also needed to do to discuss challenges involved in transferring national consumption data into a harmonized template

17 Project Phase 2 ILSI Southeast Asia Region, FAO and Food Safety & Quality Division, Ministry of Health, Malaysia (Project lead country) again jointly organized 2 nd Workshop on ASEAN Food Consumption Data and Exposure Assessment November 19-21, 2013, Kuala Lumpur, Malaysia Objectives: - Discuss finalization of common food categories for the ASEAN Food Consumption Database - Discuss challenges in transferring national data into the common template

18 2 nd Workshop Outcomes Work done and technical decisions made at the 2 nd Workshop: - Food categories for the ASEAN Food Consumption Database would be harmonized at: Level 1 Food Categories Level 2 Food Sub-categories List of food items included at Level 2 would be reported in the template, to facilitate future discussions on harmonization at Level 3 (Food Items) - To report full set of statistics for all subjects & for eaters only: Mean + SD; 1 st, 2.5 th, 5 th, 10 th, Median, 90 th, 95 th, 97.5 th 99 th percentiles - To include following age groups: Group 1 6 months to 3 years Group 2 3 year to 6 years Group 3 General population (6 years onwards)

19 2 nd Workshop Outcomes - Food categories would also be harmonized with format used by FAO/WHO to collect individual national food consumption data that would be used for international risk assessment activities by JECFA & JMPR

20 Harmonized Food Categories for ASEAN FCD NO. CATEGORY NO. CATEGORY 1 CEREAL & PRODUCTS (4 sub-cat) 2 PULSES, NUTS, SEEDS & PRODUCTS (4 sub-cat) 3 STARCHY ROOTS, TUBERS & PRODUCTS (2 sub-cat) 4 FRUITS & PRODUCTS (9 sub-cat) 5 VEGETABLES & PRODUCTS (13 sub-cat) 6 MEAT & PRODUCTS (7 sub-cat) 7 FISH, SEAFOOD & PRODUCTS (6 sub-cat) 8 EGG & PRODUCTS (2 sub-cat) 9 MILK & PRODUCTS (3 sub-cat) 11 SUGAR, SYRUP & CONFECTIONARY (3 sub-cat) 12 CONDIMENTS, SPICES & SAUCES (4 sub-cat) 13 BEVERAGES: ALCOHOLIC (3 sub-cat) 14 BEVERAGES: NON-ALCOHOLIC (8 sub-cat) 15 SNACKS NOT ELSEWHERE SPECIFIED 16 SWEETENERS & SUGAR SUBSTITUTES 17 FOODS FOR INFANTS & BABY FOODS 18 SPECIAL PURPOSE / FUNCTIONAL FOODS 19 FOOD SUPPLEMENTS & NATURAL EXTRACTS 10 FATS & OILS (3 sub-cat) 20 COMPOSITE FOODS

21 Template for ASEAN Food Consumption Database

22 Potential Uses & Benefits of the ASEAN FCD Could be used to conduct dietary exposure assessment at both the national level and regional level Countries that do not have specific data (e.g. no FCD for children or no data for certain foods) can use data of other countries to calculate exposure estimates (using appropriate assumptions) Countries that do not have any national FCD could use data of other countries in the ASEAN FCD to calculate exposure estimates ( surrogate data especially if dietary patterns considered similar, i.e. Lao & Thai) Could also be used to calculate what are ASEAN exposure estimates to a particular hazard

23 Potential Uses & Benefits of the ASEAN FCD Also relevant to the work of ASEAN WGs such as PFPWG in relation to harmonization of food safety standards, as described in the PFPWG s Decision Tree to Harmonizing Divergence on Food Safety Standards Decision by TF on Harmonization of Standards for Prepared Foodstuff on whether arisk assessment (exposure assessment) is needed on specific FSS at National or ASEAN level Risk assessment (exposure assessment) carried out at National level by AMS in relation to FSS Risk assessment (exposure assessment) carried out at ASEAN levelin relation to FSS Decision by TF on Harmonization of Standards for Prepared Foodstuff on harmonization of FSS based on risk assessment outcomes ASEAN FSS harmonized among AMSs ASEAN Standard adopted by AMSs and could also be proposed to be Codex Standard No consensus on FSS (discontinue work or continue research to re-consider the decision)

24 Next Steps for the Project ASEAN countries will begin to enter their national FCD into the common template Malaysia will continue to lead the project and help to coordinate the data collection for the ASEAN Food Consumption Database Electronic working group will continue to be used to discuss potential challenges and issues in transferring the national data into the common template Once the work is completed, the ASEAN Food Consumption Database will be developed and maintained by the ASEAN Risk Assessment Centre (ARAC) of the AEGFS

25 Future Issues for Discussion on ASEAN FCD Could food consumption survey methodologies be harmonized within ASEAN? (similar activities currently being carried out in EU, i.e. MENU Project) Could reported national data on composite foods in the ASEAN FCD be further disaggregated into food components so that accuracy of exposure estimates can be improved?

26 Scientific Cooperation Full participation by all 10 ASEAN Member States in the project Also highlights the role of ILSI in serving as a platform to facilitate scientific and technical cooperation among different stakeholders
