TRANSCRIPT
It is understood by genetically modified organism (GMO) any organism which
genetic material, by biotechnology techniques, was altered to encourage some
characteristic desired, so it does not occurs naturally.
Desired objectives with the GOM
Possibility to control:
The introduced genes;
The form of expression of genes;
Assign a form or a desired feature.
Action Insecticide
Herbicide Resistance
Pigmentation changes
Improvement of Quality Protein
Increased Productivity
Characteristics mostly desired to obtain

Most genetically modified organisms are transgenic food, however, these two concepts
are not synonymous.

Labelling
In order to be marketed, the GOM should be, initially, subjected to a very rigorous
evaluation process and then, labeled, respecting the rules on labeling and traceability of
products.
All food products containing more
than 0.9 percent of GMOs in its
composition, must include this
information on the label.

Areas of Cultivation of
GMOs in Portugal
Portugal is at position 22 in countries with transgenic crops in 2012,
with 5 million ha planted.
In Portugal the cultivation of GMOs are only of transgenic corn.
The corn crops have a transformation named as: MON810
Genetically modified with a gene to survive pests.
The main reason for the cultivation of transgenic corn by portuguese farmers are resistance to
attack by the borer, a pest that can reach serious proportions, affecting crops.

The Portuguese Environment Agency is the
competent authority in Portugal, this theme.
In order to ensure the process sustainable and
safe use of GMOs, the European Union has
established a regulatory framework.
The basic legislation is
Directive 2001/18 / EC
of 12 March, which
entered into force on 17
October 2002.
Portugal
transposed
Directive through
Decree. No.
72/2003 of 10
April.
Legislation
It is essential increase the information available on this topic and transmit it to society to understand what GMOs are, and so express your freedom to choose, even though many technical aspects are complex, one has to know!
Thank you for your attention!
