The EFSA 2008 scientific opinion concluded that epigenetic dysregulation is considered to be the main source of adverse effects that may affect clones and result in developmental abnormalities. The health and welfare of a significant proportion of clones, mainly within the juvenile period for bovines and perinatal period for pigs, have been found to be adversely affected, often severely and with a fatal outcome. The use of cloning by SCNT (Somatic Cell Nuclear Transfer) in cattle and pigs, has also produced healthy clones and healthy offspring that are similar to their conventional counterparts based on parameters such as physiological characteristics, demeanour and clinical status. In relation to food safety, there is no indication that differences exist for meat and milk of clones and their progeny compared with those from conventionally bred animals. The EFSA 2009 statement confirmed that the conclusions and recommendations of the EFSA 2008 scientific opinion were still valid.
