While much of the debate over
biotech crops has been focused on their approval before they
enter the environment or reach the market, there are significant
issues concerning post-market oversight of these crops that need
to be addressed as this technology continues to grow, according
to a new report released today by the
Pew Initiative on Food and
Biotechnology.
In "Post-Market Oversight of Biotech Foods: Is the System
Prepared?" authors Michael Taylor and Jody Tick of Resources for
the Future find that the current regulatory oversight system for
agricultural biotechnology is focused mainly on pre-market
approval and that there are potential vulnerabilities in the
system due to the relatively low priority and limited resources
for post-market oversight. Post-market oversight is intended to
ensure compliance with restrictions that agencies might impose
as a condition of approval (such as requiring buffer zones
between genetically modified and conventional crops) and to
detect and address any unanticipated health or environmental
problems that could occur after a biotech product is planted in
fields or enters the marketplace.
Although these gaps in post-market oversight have not resulted
in widespread noncompliance with regulatory requirements nor any
known food safety or environmental problems, the real challenge
for the post-market oversight system lies ahead as future
biotech products that cross traditional boundaries, such as
plants that produce pharmaceuticals, may call for tighter
regulatory control.
Two recent experiences have tested and demonstrate the
importance of post-market oversight: StarLink, a variety of
biotech corn approved only for use in animal feed but that
accidentally ended up in the human food supply, triggering
massive recalls; and the ProdiGene incident, where corn that was
engineered to produce a pig vaccine became commingled with
soybeans destined for the human food supply -- but were stopped
in the nick of time.
"Although the agencies with oversight for biotech crops have
shown substantial resilience and capacity to react to
significant problems, as was evidenced by the StarLink and
ProdiGene incidents, there are some serious questions about
whether the current regulatory regime is prepared for what lies
ahead," said Michael Rodemeyer, executive director of the Pew
Initiative. "Plant biotechnology holds promises for products
with strong consumer benefits, such as allergen-free crops or
plant-made drugs that help solve unmet medical needs, but these
new applications also call into question whether the
government's post-market oversight can ensure compliance as well
as maintain consumer confidence, which is essential to the
well-being of this industry."
Crops produced through biotechnology are currently regulated
through a patchwork of laws: the Coordinated Framework for
Regulation of Biotechnology was established in 1986, after it
was decided that no new laws were needed to regulate the
products of agricultural biotechnology. As a result, three
federal agencies (the Food and Drug Administration, the
Department of Agriculture and the Environmental Protection
Agency) use at least ten different laws and numerous agency
regulations and guidelines to address biotechnology products.
Each of the laws currently used was developed before the advent
of biotechnology products and reflects widely different
regulatory approaches and procedures.
The report identifies some gaps and potential vulnerabilities in
the post-market oversight programs established under this
regulatory framework. For example:
- USDA's Animal and Plant Health
Inspection Service (APHIS), which oversees biotech plantings,
does not have the authority under current regulations to
impose conditions on the use of biotech crops once they have
been "deregulated" (approved for large-scale planting) and
cannot require biotech developers to monitor those crops'
impact on the environment post-approval.
- Although the EPA is
responsible for setting standards to manage the environmental
impact of pesticides, including so-called plant-incorporated
protectants (or PIPs, like Bt, a bacterium that is engineered
into the plant so that it produces its own pesticide), farmers
are not legally accountable to EPA for meeting those
standards. EPA now only imposes conditions on the biotech
companies; the companies, in turn, are supposed to monitor how
farmers use their products based on what farmers tell them.
There are no official EPA standards for what constitutes an
adequate degree of compliance or government audits of how well
farmers are complying.
- Currently, the FDA has no
affirmative post-market inspection or compliance program for
biotech foods, such as it has for other categories of food and
drug products it regulates. Should there ever be a question
about whether food has been contaminated with some non-food GM
crop (such as a biopharmed plant), there are questions as to
whether the agency has the detection methods it needs, the
capacity to conduct large-volume sampling and testing, and
adequate legal tools, such as the authority, to examine food
industry records.
These gaps in current post-market
oversight programs raise some significant questions about the
degree of control society wants over the presence of GM traits
in the food supply and the roles of the government and the
private sector in achieving that degree of control. To further
explore what degree of control might be appropriate and
challenges to achieving it, the report analyzes the issues
surrounding how the regulatory system should address
adventitious presence (the low-level, unintended presence of
something other than the specific crop being sold), and the
government's role, if any, in establishing identity preservation
and traceability systems.
"Our report raises questions about the future preparedness of
the post-market oversight program to achieve its traditional
objectives, including the enforcement of regulatory restrictions
and the detection and correction of unanticipated health or
environmental problems," said Michael R. Taylor, the report's
key author and Senior Fellow at Resources for the Future. "There
almost certainly will be a need to
enhance the resources devoted to post-market oversight and to
consider strategies that effectively harness public and private
resources to ensure that consistent and credible compliance with
regulatory requirements is achieved. The time is ripe to address
these issues - before a crisis occurs."
The peer-reviewed report is based on an extensive literature
review and interviews with experts representing regulatory
agencies, various segments of the food and technology sectors
and consumer advocacy groups (from food companies, technology
providers, agricultural producers, grain traders and processors,
consumer and environmental groups, government regulators and
policy officials). A full copy of the paper, as well as the

The Pew Initiative on Food and Biotechnology is a nonprofit,
nonpartisan research project whose goal is to inform the public
and policymakers on issues about genetically modified food and
agricultural biotechnology, including its importance, as well as
concerns about it and its regulation. It is funded by a grant
from The Pew Charitable Trusts to the University of Richmond.
