Although
the term "biotechnology" is widely used, there is considerable confusion about
what it means. According to the Canadian Environmental Protection Act (CEPA), the
term refers to the application of science and engineering to the direct use of living
organisms, or parts or products of living organisms, in their natural or modified forms.
The development of new crop varieties by traditional cross-breeding is a biotechnological
process, as is the brewing of beer through fermentation.
RecombinantDNA
technology is the most recent advance in this area. Known as "genetic
engineering," it involves the application of molecular biochemical techniques to
develop new varieties or organisms, including microorganisms, crop plants, and animals.
While traditional cross-breeding techniques allow genetic combinations within the same, or
closely related species, rDNA techniques permit the transfer of genes across species
boundaries, a more controversial adaptation.
The
major federal statutes applicable to products of biotechnology are administered by Health
Canada, Environment Canada and Agriculture and Agri-Food Canada. The Canadian regulatory
system as outlined in the 1993 Regulatory Framework regulates the product not the process;
the risk-based safety assessments apply to all products, regardless of how they were
developed.
Biotechnology
offers enormous advantages in virtually all aspects of crop and animal production in the
Canadian agricultural sector. In August 1996, Agriculture and Agri-Food Canada published
regulations covering the production of new crop varieties created using recombinant-DNA
technology, biofertilizers, biofeeds, and veterinary biologics.
Given
the potential for organisms such as plants to spread and transfer genetic material
inadvertently to non-target species, the regulatory process attempts to assess potential
outcomes carefully before any modified organisms and plants are released into the
environment.
Some
modified organisms or plants have already been approved and made available to consumers;
examples are genetically altered tomatoes, rapeseed and soybeans. It is expected that
cheese, wine and dairy products might soon be produced using genetically engineered
micro-organisms. Although Canada continues to delay introduction of milk produced with
recombinant bovine somatropin (rbST), a growth hormone produced through the genetic
engineering of bacteria, this hormone was approved for use in the U.S. in February 1994.
"Functional
foods," another category of designer foods coming to supermarket shelves, have had
elements added to enhance their ability to fight a specific disease. The products tend to
blur the line between foods and drugs and consequently pose a problem for Health Canada,
which does not allow food products to make medical claims. Health Canada is in the process
of developing policy in this area.
Farmers are
starting to ask about their future role with respect to food, since these new technologies
will be controlled by private companies that determine what crops to grow, how to grow
them and the products that will be applied to them.
