1
Basic framework for risk assessment of transgenic
plants developed by OECDhistory and evolution
of OECDs risk/safety assessment
frameworkHans BergmansNational Institute for
Public Health and the EnvironmentThe Netherlands
2
1983 Biotechnology international trends and
perspectives
Blue Book Recombinant DNA Safety
Considerations, OECD 1986
  • Authors
  • scientists, academia, advisory committees
  • scientists, regulators
  • representatives of governments
  • representatives of industry

3
Blue Book Recombinant DNA Safety
Considerations, OECD 1986
  • Focus on new developments
  • Large scale industrial applications
  • Agricultural and environmental applications
  • Micro-organisms, and plants
  • Input from experience
  • GMOs
  • contained use
  • Non-GMOs
  • large scale industrial applications
  • environmental applications (plant
    protection, breeding)

4
Blue Book Safety considerations
  • Science-based risk assessment
  • Hazards/risks identified on basis of
  • properties of the recipient organism
  • technique of modification
  • properties of the GMO
  • Conjectured hazards vs. evidence for safety
  • change in pathogenic effects e.g. host range
  • toxicity
  • weediness

5
Blue Book Safety considerations
  • Appendices parameters
  • General scientific considerations
    (characterization)
  • Human health considerations
  • Environmental and agronomic considerations
    Ecological Traits Relating to the Donor and
    Recipient
  • Application of the Engineered Organism
    in the Environment
  • Survival, Multiplication and
    Dissemination in the Environment
  • Interactions of Engineered Organism(s)
    with Biological Systems
  • Potential Environmental Impacts
  • Potential risks to humans, plants and animals
    (of microorganisms)

6
Use existing data on environmental and human
health effects of living organisms to guide risk
assessments
Blue Book Recommendations
  • Ensure that recombinant DNA organisms are
    evaluated for potential risk, prior to
    applications in agriculture and the environment
  • by means of an independent review of potential
    risks on a case-by-case basis
  • Conduct the development of rDNA organisms in a
    stepwise fashion
  • Encourage further research to improve the
    prediction, evaluation and monitoring of
    applications of rDNA organisms

Risk/safety assessment frameworkCase-by-caseSt

? scale-upSafety considerations for
biotechnology Scale-up of crop plants (1993)
The concept of Familiarity
  • knowledge and experience that can be used for
  • Risk/safety analysis
  • Applying risk management
  • Indicating where more knowledge is needed

10
Common approach to risk/safety evaluation Preambl
e (1993) in Safety considerations for
biotechnology Scale-up of crop plants
  • Risk/safety analysis
  • hazard identification and, if hazard
    identified
  • risk/safety assessment
  • based on knowledge and experience familiarity
  • familiarity is not the same as safety
  • Based on
  • characteristics of the recipient organism,
  • the introduced trait,
  • the environment into which the organism is
    introduced,
  • the interaction between these, and
  • the intended application

11
Preamble in Safety considerations for
biotechnology Scale-up of crop plants
  • Risk/safety analysis
  • is based on familiarity
  • is typically an ongoing component of research,
  • development and testing of new organisms
  • is a scientific procedure does not imply or
    exclude
  • regulatory oversight
  • Operational principles
  • step-by-step next step is determined by
    risk/safety analysis
  • the steps are not fixed

12
  • Familiarity
  • For risk/safety evaluation baseline information
  • Traditional crop breeding practices (1993)
  • A historical review to serve as a baseline
  • for assessing the role of modern biotechnology
  • Soybean, Wheat, Rice, Cucurbits, Cotton,
  • Tobacco, Sunflower, Maize, Sugar beet, Alfalfa,
  • Oilseed rape, Onion, Cassava, Potato, Prunus

13
  • Working Group for Harmonisation of Biotechnology
  • Consensus Documents
  • Biology documents
  • Crop plants, trees, microorganisms
  • Trait documents
  • Virus resistance, herbicide tolerance
  • Guidance documents
  • Use of bacterial taxonomy in risk assessment

14
  • Consensus Documents
  • snapshots of current information, for use
    during the regulatory assessment of products of
    biotechnology
  • An Introduction to the Biosafety Consensus
    Documents of OECDs Working Group for
    Harmonisation in Biotechnology
  • Points to Consider for Consensus Documents on
    the Biology of Cultivated Plants (2006)
