Risks - the combination of the likelihood that the adverse consequence of a biohazardous activity will occur and the magnitude of such a consequence

Risk Assessment - the process of identifying hazards to human health and the environment that may be caused by any planned release activity, including the process of assigning magnitudes and probabilities of the adverse effects

Objective of Risk Assessment (Cartagena Protocol on Biosafety)

to identify and evaluate the potential adverse effects of LMOs on the conservation and sustainable use of biological diversity in the likely potential receiving environment, taking also into account risks to human health

Components of Risk Assessment:

1. Risk identification – what possible danger is expected if the GM plant is handled, eaten as food or feed or planted as a crop beyond that ordinarily obtained with its traditional counterpart with a history of safe use?

2. Risk evaluation – what is the probability that such danger will occur? How much damage can be expected from such occurrence? How does it compare with alternatives?

3. Risk mitigation – what measures can be adopted to reduce the probability that the danger will occur or to minimize the damage if danger occurs?

Steps in Risk Assessment:

1. “setting the scene” for the risk assessment

2. The actual risk assessment

As a first step in the RA, it is useful to “set the scene” of the assessment by listing on a cover note:

- the applicant

- the recipient organism, including whether the recipient plant can cross fertilize with wild flora and/or with cultivated crops

- the type of application (e.g. contained use, field trials under controlled

conditions or a commercial release)

- the inserted or modified genes or sequences

The actual risk assessment:

1. Identification of potential adverse effects that may arise from modification of the genotypic and/or phenotypic characteristics of LMO and its introduction to a potential receiving environment, taking into account risks to human health

2. An evaluation of the likelihood of these adverse effects being realized, taking into account the level and kind of

exposure of the likely potential receiving environment to the LMO

3. Evaluate the consequences should the identified effects be realized (the risk)

4. Consider appropriate risk management strategies

5. Estimate the overall potential environmental impact, including a consideration of potential impacts that may be beneficial to human health or the environment

5. Estimate the overall potential environmental impact, including a consideration of potential impacts that may be beneficial to human health or the environment

•Upon receipt of proposal, the NCBP will form a working group, members of which may be drawn from the NCBP itself, who will assess the proposal based on the Procedures for Evaluation (Section II, No. 3, PBG, 1991).

•Assessment of Risk will be based on the characteristics of the biological product and on the process by which it was obtained.

The NCBP Procedures for GMOs under Contained use experiment(PBG,1991)

Questions from the Procedure of

Evaluation:

• Characteristics of research

organisms(plants ; microorganisms)

•Degree of genetic manipulation

•Location of experiment

•For experiments involving rDNA plant

- Characteristics of donor DNA

- Construction method of rDNA

•For experiments involving rDNA microorganisms

-characteristics of the recipient organisms

- pathogenicity, active compounds

- characteristics of donor DNA

- characteristics of rDNA organisms

- epidemiological factors

- laboratory environment

The risk assessment should be carried out case by case and on the basis of transformation event

The risk assessment done on the particular GMO will determine the required biosafety level

Containment

Containment describes the safe method for maintaining control over the distribution of GMOs in the laboratory and in the environment

Biological containment - involves the use of

specific combination of vector and host to

reduce the probability of transfer of a

vector to an unintended host and to limit

subsequent survival of the host-vector

combination in the environment.

Physical containment - involves physical

constraints on the movement of GMOs of

uncertain risk or potential hazard. It

involves well qualified and competent

personnel who follow safe, standard

procedures, and a working environment

designed to prevent unintended spread of

GMOs in the environment

Biosafety level 1 – is suitable for work with

strains of viable organisms that are known

not to cause disease in humans, animals,

and plants. Appropriate for undergraduate

and secondary laboratory work

Biosafety level 2 – is suitable for work

involving GMOs with moderate potential

hazards to humans and environment.

Personnel are trained to handle the GMO and

access to the laboratory and containment

facilities are limited

Biosafety level 3 – is suitable for work with

indigenous or exotic agents that may cause

serious or potential lethal disease as a result

of exposure. Requires personnel training,

strict working practices, qualified supervision,

and strict physical containment.

Biosafety level 4 – is suitable for work

involving agents that pose a high individual

risk of life-threatening disease. Requires

personnel training, strict working practices,

qualified supervision, and strict physical

containment.
