Earlier this month, a committee of the National Ac
ademy of Sciences released a
report that examines the safety of crops made with genetic engineering. The report
is expected to influence the debate in the United States about the products of
genetic engineering. Genetic engineering is the technology of cha
nging the genes
of living things.


The National Academy of Sciences is a private group established by Congress
more than one
-
hundred years ago. Congress directed the Academy to advise
government officials about science and technology.


The new report exa
mines the safety of plants treated with special genes to resist
insects and disease. Last year, farmers planted more than thirty
-
million hectares of
genetically
-
engineered crops in the United States.


The committee that wrote the report said it found no e
vidence suggesting any food
being sold now is unsafe to eat because of genetic changes. However, it urged
American officials responsible for such crops to do more to protect public health
and the environment.


The report notes that few of these crops have

been shown to cause health or
environmental problems. However, it said changes in the treated plants should be
closely watched. And, it called for improved methods for identifying genes that
could cause harmful reactions in humans.


The scientists examin
ed environmental concerns, including the idea that treated
plants could influence other organisms. They proposed more studies to identify
rates at which insect
-
resistant genes might spread and to develop methods to
decrease the spread.


The report also ca
lled for improvements in the way the government supervises
genetic engineering. Committee chairman Perry Adkisson says public acceptance
of genetically
-
engineered foods depends on independent testing and government
rules. He said the testing and rules must

be complete and based on accepted
scientific ideas.


A trade group representing more than nine
-
hundred companies and research
centers praised the findings. A spokesman said the report confirms that
genetically
-
engineered foods are safe. However, environm
ental and other groups
were more critical. They said some of the people who wrote the report have close
ties to the biotechnology industry.
