  • Hello, my name is Claudia, I am a scientist and

  • I work in EFSA, the European Food Safety Authority.

  • I'm here today to talk to you about the work we do

  • on genetically modified organisms, and why we do this work.

  • Let's start from the beginning of the story.

  • What is a genetically modified organism?

  • It is an organism in which the genetic material

  • has been altered or changed in a way that does not occur naturally.

  • And by naturally, we mean, for example in the case of GM plant

  • when we combine a father plant with a mother plant to obtain a new plant.

  • Scientists are developing many different types

  • of GM plants to achieve different objectives.

  • For example, they have developed plants which are called

  • drought-resistant’, meaning that they can

  • survive well also when water availability is quite limited.

  • Other types of plants are calledinsect-resistant’,

  • and this is the example we will be using today to explain a few things.

  • Here you see two drawingswe have the non-GM maize plant

  • and we have the GM maize plant.

  • What's the difference between the two?

  • On the non-GM maize plant we have insects that can feed on iton its leaves

  • whereas these are absent here because this plant is resistant

  • and the insects cannot feed on its leaves.

  • Now what is the job of EFSA?

  • The job of EFSA is to assess whether this plant

  • is as safe as this onethe non-GM counterpart.

  • Now the question is how does EFSA do this assessment?

  • Using a comparative approach, which is basically a comparison between

  • the GM plant and its conventional counterpart.

  • We do that by asking a whole series of questions.

  • For example, is this plant as nutritious as the non-GM counterpart

  • for animal and humans when used in food and feed?

  • Another question: does this plant cause any allergic reaction

  • in humans or animals when used, in comparison to the non-GM counterpart?

  • Or is this plant toxic for animals or humans in comparison to their

  • non-GM counterpart when used?

  • In addition to that, we also ask a whole series of questions

  • to assess whether this plant causes any harm to the environment when cultivated.

  • After we collect all this amount of scientific information,

  • we use it to compile a document which in EFSA we call a scientific opinion,

  • and this scientific opinion is then delivered to policymakers.

  • This document contains all the information

  • and the evaluation of the safety of the GM plant.

  • In such respect, EFSA is not in favour nor against GMOs

  • because it does purely a scientific work,

  • and its opinion is used then by policymakers who are

  • the ones ultimately responsible for the decision-making process

  • and can authorise or not a GM plant on the European market.

  • Thank you.
