Genetically Modified Organisms (GMO's) - an introduction

There has been a general perception in the media and with the public at large that GMO's exist largely in the form of new crops producing Frankenstein Foods. In fact there are many different types of GMO under production, some of which we consume on a regular basis.

This includes organisms designed to manufacture proteins as well as modified crops and farm animals. Broadly we can classify these as Indoor -meaning laboratory based, and Outdoor meaning those found outside of the lab.

The most visible manifestation of these however is GM crops which have attracted much media attention.


statutory controls govern the use of GMO's in the UKAll GMO's are strictly controlled by law. Production and research is subject to inspection by the HSE whilst the release (eg the sale of a GM crop to farmers) is subject to the GMO (Deliberate Release) regulations. Any use of a GMO as a food is controlled by the Novel Food Regulations.
