Globally, GM mammals and birds are being developed for a range of purposes, including use as food, pets or for production of pharmaceuticals. There is a requirement, therefore, for an analysis of the type of expertise and data required to conduct an environmental risk assessment (ERA) of GM mammals and birds to be commercially released into the EU environment.

A searchable database of expertise relevant to an ERA was established – information was collated against scientific disciplines, fields of expertise, research institutes, and academics/experts. A database of GM species and traits where substantial progress has been made towards commercial use was compiled; theoretical case studies were also used to allow the development of a comprehensive list of criteria to be considered in an ERA.

The potential adverse effects of GM mammals and birds on the environment, their consequences and likelihood were identified. Crucial mammal and bird characteristics, baseline information about receiving environments and approaches using modelling and surrogate non-GM species were evaluated for their utility in an ERA.

The identification of the characteristics of GM mammals and birds that influence their potential risk to the environment has a corollary in the evaluation of risk posed by non-native species. It was concluded, therefore, that criteria should be considered at each stage of an invasion process (introduction, establishment and spread) and consider the inherent risk posed by the non-GM parent species and the effect that the genetic modification may have on that inherent risk. Consideration should also be given to any infectious diseases, or agents, that may be carried by the species and how these may be influenced by the genetic modification.
