Slide1

Science - the basis of CODEX workSlide2

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 evidenceFood safety risk assessment should be based on sound data and includes four steps processFunctional separation of Risk Assessment & Risk Management

Science guides the whole process of Codex work

Slide3

Codex Process:

Science-based, Participatory and Transparent

Scientific advice

Requests for advice, risk assessment

CODEX

ALIMENTARIUS

COMMISION

JECFA

(food additives, veterinary drug residues, contaminants in food)

JMPR

(pesticide residues in food)

JEMRA (microbiological hazards in food)

ad hoc expert consultationsemerging issues (e.g. Nanotechnologies in agri-food sector)

International Risk Assessment

International

Risk ManagementSlide4

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 standardizationExistence of duplication with work already undertaken in this areaVolume of production and consumptionMembers can request for prioritization of work

Provide

scientific arguments

to include topic in the priority list

Provide

dataSlide5

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 grainScience 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 actionSlide6

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 USsGeneral 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 concludedImplementation 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 retainedSlide7

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 guidelinesFAO/ 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

VibrioSlide8

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 Codexto actively guide the stds development process to ensure global relevance of Codex outputs
