  1. T.L.B. Work EsaT Project: Transgenic Food

  2. Introduction The objectives of this work are: ► To study the level of knowledge of a population (students of Escola Secundária da Amadora) about transgenic and biological food. It was made an inquiry to 116 elements of our population. ► To inform the students about transgenic and biological products.

  3. 3. Did you ever consume transgenics? 19% Yes 11% No Don’t Know 1.Do you know what transgenic 70% food is? 2.Do you know what biological food is? 43% Yes No 57% 4.Did you ever consume biological products? 0% Yes No 14% 7% Yes No 100% Don’t know 79% The answers to the inquiry were:

  4. After the study of this results we came to the conclusion that almost half of the students asked don’t know what transgenics are. Even those who indeed know, still can’t tell whether they’re consuming them or not. It is certain, however, that these numbers would increase if this questions were applied outdoors. Nevertheless, it seems everyone knows what biological food is. So, we decided to only approach the transgenic theme.

  5. But, after all, what is transgenic food??? ► Trangenics are composed aliments, that contain genetically modified organisms or genes. ► They are organisms made in laboratory with genetic engineering techniques that allow the scientists to isolate a gene from another species that contains the characteristic we want our organism to have and insert it in the plant in study, manipulating its natural structure.

  6. Do they have more advantages or disadvantages? The answer to this questions is very complicated and there is no consent about it yet. Advantages - The aliment can be enriched with a nutritional component. - The aliment will be able to prevent, reduce or avoid disease risks. - The plant can resist to an insect attack, seca or geada. - Increase of agricultural productivity through the development of more productive lavouras..

  7. Disadvantages - Increase of toxic substances - Increase of antibiotic resistance - Risks to the environment - Increase of allergies - There is no knowledge of the GMO’s effects at a long term; they can cause allergies and diseases only identifiable after a long consume.
