Call for data for further advice on the implications on animal cloning (SCNT)

29 April 2009

The European Commission has requested EFSA for further advice on the implications on animal cloning (somatic cell nucleus transfer, SCNT). The request is related to the recommendations included in the Opinion of the Scientific Committee of July 2008, in particularly those on the health and welfare aspects of animal clones.

EFSA is asked to consider information from new scientific evidence that could include information from as yet unpublished data which may be available from experts working in the area. In addition EFSA is to provide an update on the extent the current knowledge would apply to cloning of sheep, goats and chicken.

Call for Data
To address the request of the European Commission EFSA is publishing this Call for Data seeking scientific contributions from third parties. Specifically EFSA is seeking information which has become available since January 2008. Such data could refer to new scientific publications, as well as to scientific information which is not yet published.

EFSA encourages submission of peer reviewed data as the most relevant and reliable documents. Non peer reviewed data will be considered if they are based on scientific evidence and if they meet adequate quality standards, e.g. publications “in press”, technical reports or other scientific documents or data.

EFSA would appreciate receiving data, since January 2008, in the following areas:

  • Health and welfare of animal clone during their production life and taking into consideration their natural life span;
  • Information on the causes of pathologies and mortality observed in clones during the gestational and juvenile periods and those observed at a lower frequency in adulthood.

EFSA is also seeking information in relation to the extent the current knowledge would apply to cloning of sheep, goats and chicken. Such information could relate to:

  • Health and welfare of the surrogate mother and the animal clone;
  • What extent epigenetic dysregulation occurring in clones is transmitted to progeny (offspring);
  • Characterization of the genetic make-up of animal clones, considering both intranuclear and extranuclear (mitochondrial) genetic material;
  • Comparative physiology of clones and conventional animals, including reproductive capacity;
  • Safety of consumption of animal clones and their products (meat, milk products, eggs), including compositional and nutritional characteristics.
