Call for Data on Level of Acrylamide in Food and the
In order to perform a risk assessment of acrylamide in food, the levels
of acrylamide in the total diet are required to provide an exposure assessment
for the general population as well as certain vulnerable groups. This
can be estimated from levels of acrylamide in individual foods or by conducting
total diet studies, such as market basket and duplicate diet studies.
Levels of acrylamide in food can also inform on foods and processing methods
that offer risk management options which may need to be considered. Consequently,
a call for data is being made for representative data on levels of acrylamide
in food and the total diet which is both reliable and comparable at the
international level. Ideally, samples should be representative of the
entire country. Data from developing countries is particularly encouraged.
In addition to researchers and other users, these data will be provided
to the Joint FAO/WHO Expert Committee on Food Additives (JECFA) for its
safety evaluation of acrylamide in food. All data submitted will be provided
to JECFA. Data that is deemed "confidential" by the submitter will be
appropriately protected according to the current JECFA practice. In addition,
limited access to aggregate data, i.e. mean, median, and 90th percentile
levels, for acrylamide in food and food groups and total dietary exposure
data will be made possible through this Web site. Data on individual food
items will not be accessible without the consent of the data submitter.
Submission of Data
Historically, institutions have submitted data on levels of chemicals
in food and the total diet to the WHO Global Environment Monitoring System
/ Food Contamination Monitoring and Assessment Programme (GEMS/Food) using
standardized data forms. In 1996 GEMS/Food started the development of
a new data structure and protocols for the electronic submission of such
data. These protocols involve encoding and formatting of data in a manner
that is compatible with the database maintained at WHO Headquarters in
Geneva. These protocols are also consistent with the database used to
disseminate data through the SIGHT (Summary Information on Global Health
Trends) portal, which provides public access to a number of important
WHO databases. By following the protocols and completing all data fields,
the quality control of electronic data submissions is simplified and improved.
Consequently, data submission should conform to the protocols for individual
and aggregate data on levels of acrylamide in specific food commodities
and levels in the total diet of the general population and selected subgroups.
Data should be submitted using one of the three Excel templates provided.
These templates are identical to those used by GEMS/Food except for additional
fields for the identification of foods. While GEMS/Food has collected
data on contaminants in raw agricultural commodities, acrylamide is most
often associated with processed food. Consequently, several additional
fields have been added to better identify the food and its processing
(see Field 4). To complete these fields, several Excel spreadsheets are
attached to provide appropriate codes. For all other fields, more detailed
descriptions and codes are provided in the GEMS/Food Electronic Reporting
Manual available at the WHO Website - http://www.who.int/foodsafety/publications/chem/en/gemsmanual.pdf.
If data being submitted are intended for evaluation by the Joint FAO/WHO Expert
Committee on Food Additives (JECFA), additional information should be
provided to allow reviewers to independently assess the quality of the
analytical work and the adequacy of the sampling plan. This information
should be provided as a separate submission according to the questionnaire
provided in Appendix 5 of the above mentioned reporting manual. Unless
the questionnaire is completed, the full use of the submitted data may
Follow the steps provided below to submit the data:
Download the following Excel files:
- Acrylamide Templates
- This Excel workbook contains three worksheets to enter information
about individual, aggregate, and total diet data.
- Acrylamide Tables
- This Excel workbook contains supportive information to fill out the
Acrylamide Templates. The five Excel spreadsheets include information on CCFAC Food
Categories, Codex Food Classification Codes, WHO Country Codes, Heating
Codes, and Pretreatment Codes.
Fill out the appropriate Acrylamide Template with the help of supportive
information from the Acrylamide Tables as well as from GEMS/Food Electronic Reporting Manual.
