On his visit to Rothamsted Research in Hertfordshire Mr Paterson visited the field where the active GM crop trial is taking place.
The field, which is surrounded by a high fence, has security guarding it 24 hours a day and signs warn of guard dogs.
Everyone going through the gate next to the field had to sign a book as part of the tight security process - even Mr Paterson.
Before taking the trip out to see the crop trial, Mr Paterson toured the laboratories and had a go at using a particle gun, which is used in the GM process
