pesci transgenici: USDI esprime preoccuapzioni
Ancora una volta il messaggio e' lo stesso: c'e' troppa fretta nel
rilascio di organismi transgenici.
Il dipartimento US degli affari interni invita alla cautela
nell'introduzione nell'ambiente di pesci modificati geneticamente.
(Modelli indicano che i salmoni transgenici possono causare l'estinzione
della popolazione selvatica).

William Brown, a science adviser to Interior Secretary Bruce Babbitt,
said the department was concerned that some new genetically altered
organisms could inadvertently harm the environment, much like invasive
plants.
For example, the less than 200 remaining Atlantic salmon living in
Maine
rivers could be quickly wiped out if transgenic fish grown in nearby
aquaculture farms escape their pens, Brown said.
A similar risk is posed by developers of transgenic aquarium fish,
which
are engineered to be bigger, stronger and more colorful than
conventional
varieties.
"Maybe the situation can be managed just fine," Brown told a National
Academy of Sciences committee studying biotech food and
environmental issues. "But I'm worried that some of these species are
falling between the cracks of current regulations."
He urged the committee to take a close look at how federal safeguards
can be developed for organisms that might be a new threat to
endangered species.
U.S. regulations for genetically modified organisms are administered
by
the Food and Drug Administration, the Environmental Protection Agency
and the U.S. Agriculture Department. The FDA handles food safety and
labeling, the EPA monitors crops engineered to repel pests, and the
USDA oversees field testing of transgenic crops.
The Interior Department, which has taken little part in federal
biotech
policies, administers public lands as well as protecting endangered
species.
