Can we guarantee the safety of genetically engineered organisms in the environment?

Abstract

Concern about the safety of genetically engineered organisms in the environment arises from the undesirable results of earlier new technologies and introduced organisms. Progress towards safe release is complicated by the varied views of a diverse society, confusion of process and product, problems with existing methods, and the lack of practical experience with real releases. No categorically safe novel organisms exist, but a progressive series of releases should allow risks to be systematically reduced.
