European Union environmental officials have determined that two kinds of
genetically modified corn could harm butterflies, affect food chains and disturb
life in rivers and streams, and they have proposed a ban on the sale of the
seeds, which are made by DuPont Pioneer, Dow Agrosciences and Syngenta. The
preliminary decisions are circulating within the European Commission, which has
the final say. Some officials there are skeptical of a ban that would upset the
powerful biotechnology industry and could exacerbate tensions with important
trading partners like the United States. The seeds are not available on the
European market for cultivation.
In the decisions, the environment commissioner, Stavros Dimas, contends
that the genetically modified corn, or maize could affect certain butterfly
species, specifically the monarch, and other beneficial insects. For instance,
research this year indicates that larvae of the monarch butterfly exposed to the
genetically modified corn ’’behave differently than other larvae.’’ In the
decision concerning the corn seeds produced by Dow and Pioneer, Mr. Dimas calls
’’potential damage on the environment irreversible.’’ In the decision on
Syngenta’s corn, he says that ’’the level of risk generated by the cultivation
of this product for the environment is unacceptable.’’
A decision by the European Union to bar cultivation of the genetically
modified crops would be the first of its kind in the trade bloc, and would
intensify the continuing battle over genetically modified corn. Banning the
applications for corn crops also would mark a bold new step for European
environmental authorities, who are already aggressively pursuing regulations on
emissions from cars and aircraft, setting it at odds with the United States and
angering industries.
’’These products have been grown in the U.S. and other countries for
years,’’ said Stephen Norton, a spokesman for the United States trade
representative. ’’We are not aware of any other case when a product has been
rejected after having been reviewed and determined safe’’ by European food
safety authorities, he said.
Barbara Helfferich, a spokeswoman for Mr. Dimas, declined to comment on the
specifics of the procedure because commissioners had not yet made a final
decision. But she said that the European Union was within its rights to make
decisions based on the ’’precautionary principle’’ even when scientists had
found no definitive evidence proving products can cause harm. She said that the
decisions by Mr. Dimas could go before the commission within a few weeks, but
she said that no date had been set. In the decisions, Mr. Dimas cited recent
research showing that consumption of genetically modified ’’corn byproducts
reduced growth and increased mortality of nontarget stream insects’’ and that
these insects ’’are important prey for aquatic and riparian predators’’ and that
this could have ’’unexpected ecosystem-scale consequences.’’
Although still preliminary, his decisions could drastically tilt the policy
against future approvals of genetically modified crops, said Nathalie Moll, a
spokeswoman for Europabio, an industry group with 80 members including Syngenta,
Pioneer and Dow. Europabio says that the crops grown using the genetically
modified corn are already imported into several European countries, including
France and Germany, where they are used to feed animals like cows and
chickens.
Rob Gianfranceschi, spokesman at the United States mission to the European
Union in Brussels, said it was too early to comment on a decision that had not
yet been formalized. But he made clear that the United States remained
frustrated with European policies on genetically modified crops.
