HC Deb 16 May 1988 vol 133 cc329-30W
Mr. Allan Roberts

To ask the Secretary of State for the Environment if he will consider restricting approval of release of genetically engineered micro-organisms to products which have a clear benefit to human health or the environment.

Mr. Moynihan

Only a few proposals for planned release have been received so far. These have been on a small scale and have been aimed at gaining knowledge on several aspects of the new technology. Releases have only taken place after a full independent assessment of their safety to man and to the environment. The Government will review the position on restricting planned releases in the light of accumulated experience, and of the advice of the Royal Commission on environmental pollution, which is expected by early next year.

Mr. Allan Roberts

To ask the Secretary of State for the Environment what methods are available for detecting and tracking genetically engineered micro-organisms which are produced without marker genes.

Mr. Moynihan

Genetically engineered microorganisms can be detected and tracked in the environment by a variety of methods besides marker genes. Examples of other methods include gene probes, antibodies and enzyme abundance assays.

Mr. Allan Roberts

To ask the Secretary of State for the Environment if he will consider prohibiting the environmental release of genetically engineered micro-organisms which are marked with antibiotic resistance factors.

Mr. Moynihan

Each proposal for the release of a genetically manipulated micro-organism is examined individually by appropriate expert advisory bodies. Any use of antibiotic resistance markers is one of the aspects which are specifically considered. Although the use of other types of markers is generally recommended, antibiotic resistance factors have been used, but only those which already occur in nature.
