This document provides an overview of transgenic or genetically modified foods. It discusses how genetic engineering is used to introduce new genes into plants, crops, and animals to improve traits like disease resistance, growth rate, and nutritional content. Both advantages and risks of GM foods are outlined, such as increased production but also possible contamination and loss of biodiversity. The situations regarding GM foods in the United States, Europe, Spain, and Catalonia are briefly summarized. The United States largely embraces GM crops while Europe takes a more cautious approach with strict regulations. Spain and Catalonia have significant GM crop cultivation within Europe.

3. What are transgenic
foods?
A transgenic or genetically modified food is that
which, through genetic engineering, has introduced a
gene, called transgene or has been deleted or
changed gene itself.

4. Plants and GM crops.
Genetic modification of plants and crops currently occurs in a
very usual. Thus we attempt to achieve greater productivity
and improved food crops produced. Also used in the
production of medicines, vaccines, etc..

5. Corn
The corn is more
resistant to insect attack
thanks to carrying a gene
from the bacterium
Bacillus thuringiensis.

6. Potatoes
The transgenic potato
containing starch rather
take a golden color and
without much oil when
frying.

7. Rice
The transgenic rice is
capable of producing
vitamin A: required to view,
to prevent vision problems
associated with diets of
the vitamin.

8. The transgenic animals
A genetically modified animal containing one or more
genes that do not belong to the animal is any product
of interest.

9. Salmon
Some fishes, with the idea that they grow faster,
companies make that it workers introduce the
hormone of growing, it's the case of salmon.

10. Animals producers of milk
Companies want that some cows, goats and sheep
produce milk with less lactose, with the idea that
poeple is allergic to it, can drink that.

11. How to have a modified
genetically a animal
1. Create an ADN recombinant
that has the gene of interest
2. Introduce the ADN modified
to mammalian cell
3. Find the proteine of intereste
made

12. Improvements in genetically
modified food
-The maturation is slower.
-Improvement of quality.
-Production of substances.
-Resistance to herbicides and pesticides.

13. Are the MG a danger?
Avantatges:
-Possibility to eat food with a bigger
valor of nutrition and less grase.
-Production of fatty acids for specific
use, nutritional or industrial.
-More time of conservation of the
products.
-More production.
-The plantations give more products.

14. disadvantages:
-Can be hibridation.
The gene can be developed how it wasn't
provided.
-The floor and the water can be
contaminated by the excess of the toxine.
-Can appear virus or weeds more violent.
-The genetically modification is
contagious.
-With that, companies have the power in
food, sometimes the GMO is more
expensive than conventional food.
-The biodiversity is lost.
-They aren't labeled in the trade.

15. Situation in USA
The goods are for USAs farmers
Usa introduced MGs in trade without
announcement
USAs farmers likes MG, so they don't use a lot of
chemics
The little contries that doesn't accep MG, are
threaten by USA
USA forced farmers to use MG
USA companies of food, say that their MG are
healthy
USA says that MG are gonna save world hunger

16. Situation in Europe and the rest of
the world
Europe no recieves good from GM
The movement no-GM started in Germany
Europe attacked hard big companies, and they stop to
sell GM products in Europe
In 2001 Europe aproved GM products with big controls of
them
They say that the nutrition wolrd problem, is a problem
of distribution
The fishes modified genetally are extremly dangerous
We will depend of GM products

17. Situation in Spain
The European Union is against the planting
of transgenic seeds and in general. Spain
is the first country to use the method of
cultivation
Aragon and Catalonia are the regions with
highest number of plantations.
Currently there are more genetically
modified plants animals corn, soybeans
and cotton are major crops modified by
man.

18. Situation in Catalonia
Nowadays Catalonia is the community that
has more transgenic plantations of Spain,
Catalonia is the second European territory
where more GMOs are grown in Europe,
especially corn, with 26,000 hectares.
Currently, a project being proposed against
transgenic foods in Catalonia.
