Science - the basis of CODEX work
The Role of Science in Codex Decision-Making
Key principles Risk analysis guide Codex stds from development to
implementation Codex texts shall be based on science and evidence Food safety risk assessment should be based on
sound data and includes four steps process Functional separation of Risk Assessment & Risk
Management
Science guides the whole process of Codex work
Codex Process: Science-based, Participatory and
Transparent
Scientific advice
Requests for advice, risk assessment CODEX
ALIMENTARIUSCOMMISION
• JECFA (food additives, veterinary drug residues, contaminants in food)
• JMPR (pesticide residues in food)
• JEMRA (microbiological hazards in food)
• ad hoc expert consultations
emerging issues (e.g. Nanotechnologies in agri-food sector)
International Risk Assessment International Risk Management
Criteria for the Establishment of Codex
Work Priorities Contribution to the protection of consumer health Diversification of national legislations and potential
impediment to international trade Product suitability for standardization Existence of duplication with work already undertaken in this
area Volume of production and consumption
Members can request for prioritization of work
• Provide scientific arguments to include topic in the priority list
• Provide data
Sorghum - mycotoxin formation Concerns raised in the Codex
Committee on Contaminants as to human health impact
Important staple food in many African countries
Lack of information on formation and levels of mycotoxins in grain
Science to start work: the case of Sorghum
FAO/WHO are implementing a project with funding from EC in Burkina Faso, Ethiopia, Mali and Sudan to
gather data and knowledge to feed back into the discussion at
international level on options for action
Science to update work: the example of Fumonisins
Fumonisins were previously evaluated by JECFA in 2001 The 3rd Session of the CCCF agreed to initiate work on establishing MLs for fumonisins in
maize and some maize-based products Data were submitted only by Argentina, Australia, China, Japan, Nigeria, EU, the UK and USs
General agreement on the need for MLs but not on the levels The 4th session CCCF agreed to retain the proposed draft MLs at Step 4 until further advice
was provided by JECFA JECFA (June 2011) evaluation concluded
Implementation of the MLs proposed by CCCF could significantly reduce exposure to total fumonisins
the proposed MLs would result in rejection of 2–88% of “Corn/maize grain, unprocessed” and 4–57% of “Corn/maize flour/meal” across the clusters.
submitted data show that the exceedance of the PMTDI occurs only in limited regions presenting high maize consumption levels and highly contaminated maize.
PMTDI for fumonisins was retained
Codex Guidelines on the Application of General Principles of Food Hygiene to the Control of Pathogenic Vibrio Species in Seafood in have been developed in 2010
CCFH requested FAO/ WHO to work on risk assessment tools to facilitate the implementation of Codex guidelines
FAO/ WHO work An expert meeting was organized in Ottawa, Canada on October 17-19, 2011 to:
(a) identify possible end uses of Vibrio methodologies (b) look at the performance characteristics of available methods and provide recommendations on the requirements for different end uses (c) provide recommendations for collection of data to support national/regional risk assessments.
The output of this Expert Meeting and subsequent discussions are being used to develop a “Guidance document” addressing performance characteristics of Vibrio methodology and approaches for data collection.
As a follow up to this, a Regional training Workshop for Asia on Vibrio methodologies is scheduled to be held in Singapore during November 19-23, 2012.
Science to implement work: the case of Vibrio
Conclusions
Science guide Codex working process from stds development to implementation.
It is essential that countries generate science data/information to support their positions at Codex to actively guide the stds development process to ensure global relevance of Codex outputs
