Title: Regulating GMOs: A Precautionary Approach


1
Regulating GMOs A Precautionary Approach
  • Team SymBiotek
  • Ayat Al-Bassam
  • Darcy Helbig
  • Vraj Rabadia
  • Rob Urbanic

2
What is the future with no regulation?
  • Two genes from daffodil and one from a bacterium
    have been inserted into rice. Golden rice
    produces beta-carotene, which the human body
    converts to vitamin A.
  • Researchers are increasing the anti-oxidant
    properties of tomatoes by engineering them to
    synthesize more lycopene.
  • Hiridin, a human coagulant protein, produced in
    transgenic canola, is available commercially in
    Canada.
  • Corn has been genetically engineered to make an
    antigenic protein from HIV. Tests in animals are
    in progress for immune responses after ingestion
    of the transformed corn.

Regulation of Food Biotechnology Should Occur at
all Levels of the Food Supply Chain
Growth Hormones, Antibiotics
GM Feed
Consumer Products
4
Current Canadian Regulations
  • Regulatory guidelines are broad and loosely
    defined
  • Guidelines are based on substantial equivalence
  • Developer driven - companies responsible for
    providing data
  • No formal criteria or decision making framework
    exists - decisions are made on a case-by-case
    basis

5
Substantial Equivalence
  • Essentially similar to its conventional
    counterparts OECD 1993
  • Lack of specificity, ambiguity and loose format
  • i.e. If it looks like a duck and it quacks like
    a duck, therefore we must assume that it must be
    a duck or at least we will treat it as a duck
  • Not a scientific formulation for assessment it
    is a conceptual tool and it does not specify or
    limit amount of testing needed
  • Biased interpretation can diminish the purpose of
    regulation

6
Regulation of Environmental Issues
  • GM-crops No reduction in chemical use! (Benbrook
    2003)
  • Pre-mature technology Bt-cotton, Rr-canola
  • Development of pest resistance European corn
    borer
  • Effects on non-target organism Monarch Butterfly
  • Superweeds and gene flow Isolation issues
  • Biodiversity Domestication v/s Transformation
  • Need for Long-term Environmental Impact Assessment

7
Risks of GM Foods to Human Health
  • Creation of novel toxicants or increased
    expression of known toxicants
  • Creation of novel allergens
  • Development of new allergies from
    increased total dietary exposure
  • Anti-nutrients
  • Antibiotic resistance genes used as selection
    markers

8
Can the current system accurately predict the
risks?
  • Identifying unintended effects pleiotropy
  • Health Canada assumes substantial equivalence
  • Toxicological testing at a whole food level is
    needed
  • GM products with human food counterparts that
    carry restrictions on their use for non-food
    purposes
  • StarLink

9
Socioeconomic Issues
  • Intellectual property rights
  • Broad patents restrict innovation
  • Monopolistic restrictions
  • Agro corporations have excessive control on
    agricultural practice
  • Licenses, restrictive agreements
  • Farmers traditionally retained seeds for the
    next season (brown bagging)
  • Reduced acreage of GM crops
  • Terminator gene and sterile seeds

Regulation must be based on social justice
10
Labeling
  • Current government policy supports voluntary
    labeling of GM foods
  • Label should include allergens, composition or
    nutrition changes
  • Labeling of GM foods should be mandatory
  • GM foods/feeds
  • Products containing GM ingredients
  • Informed consumer choice
  • Traceability of transgenic source
  • Accountability for adverse events

11
Recommendations
  • Depart from assumptions (substantial equivalence)
    to scientific proof.
  • Approval of novel GMOs should be based on
    rigorous scientific risk assessment conducted by
    open consultation with expert scientific
    community.
  • Establish detailed guidelines describing the
    testing of GMOs for production, marketing and
    after-market surveillance (build databank
    listing).
  • Implement more restrictive guidelines regarding
    the nature of intellectual property.
