Genetically Modified Crops

Are GM crops safe?

When it comes to the issue of GM and safety, there are two quite separate questions that need to be addressed.

The Precautionary Principle

At present, there are very few GM crops grown in Europe, as the EU has applied what is known as the Precautionary Principle to GM crops. This requires that in the face of scientific uncertainty, a country should not take any action that might adversely affect human and animal health or harm the environment.

In practice, this shifts the responsibility on to GM proponents to prove that GM technology poses no risk. However GM supporters have argued that:

  • it is impossible to prove a negative and that
  • all human activity carries risk.  

 Are GM foods safe for people?

GM as a technique Vs Specific uses of GM

GM is a very new technology, so its easy to associate the whole of GM (as a technique) with those specific applications of it that we hear about in the media. Next time you hear about a GM use, ask yourself:
Is this a problem with GM in itself or is this just a good/bad use of the technology?

Activity: Read
these pages on safety of GM crops and then go to the online discussion on GMOs to have your say.
