Cloning animals means creating animals by using the genetic material from a cell from another animal. It is a form of asexual reproduction performed in a laboratory. The closest natural analogy to a clone is identical twins. As identical twins, clones and cell donor animals share exactly the same genetic information (DNA). Cloning does not involve any genetic modification. In fact, the clone is a near exact genetic copy of the donor animal. Currently, cloning is used for research purposes in the EU.

At present food from clones is regulated and subject to a European Union (EU) authorisation under the Regulation (EC) No 258/97 on Novel Food. According to this regulation, food products from cloned animals have been subject to a pre-market authorisation. Member States report that no cloning is taking place on their territory for food production, so no application has been submitted so far and therefore no authorisation granted.

The Commission adopted a proposal for a new Regulation on novel foods in January 2008 streamlining the approval process of the 1997 Novel Food Regulation. Inter-institutional discussions started in 2009. The European Parliament (EP) adopted amendments on first reading (legislative resolution of 25 March 2009) and on second reading (legislative resolution of 7 July 2010) following the Council’s position at first reading on 15 March 2010. To help to find a balanced solution the Commission adopted an opinion on the EP’s amendments to the Council’s position on 11 October and a report on animal cloning for food production on 19 October 2010. However no agreement could be reached and the conciliation committee failed in March 2011.

Subsequently, the Commission included in its work programme for 2012 new legislative initiatives on cloning which were outlined in its relevant roadmap . As a result of the work programme, the Commission adopted two proposals for directives on cloning of animals on 18 December 2013.

The draft directive on cloning of animals aims to ban temporarily the use of the cloning technique on EU farmed animals (bovine, porcine, ovine, caprine and equine) and the placing on the market of live animal clones and embryo clones. The draft directive on the placing on the market of food from animal clones aims to ban the imports into the EU of food such as meat or milk from animal clones. Cloning will be allowed for purposes such as research, conservation of rare breeds and endangered species or for use in the production of pharmaceuticals and medical devices, where the technique can be justified.

International aspects are also involved. The proposals were notified under the Technical Barriers to Trade Agreement of the Wold Trade Organisation (WTO) and were sent to the Sanitary and Phytosanitary Standards Committee of the WTO for information. Regarding current negotiations on the Transatlantic Trade and Investment Partnership , Members have expressed caution with regard to several sensitive issues, for instance differing perceptions towards Genetically Modified Organisms and cloning and with regard to safety standards, invoked in the EU’s precautionary principle .

The legislative procedures are on-going in the EP. It can be estimated that the draft legislation will enter into force in 2016 at the earliest.

When speaking of cloning of animals some concerns emerge: ethical principles, the conditions such that animals’ health and welfare are guaranteed, the respect of the genetic diversity and the negative perception that EU citizens have of the cloning technique used for food production. This EPRS keysource aims at showing publications on these concerns, views of the new proposals for directives and analysis on cloned animals.


The Commission’s press release , MEMO and citizens’ summary (published on 18 and 19 December 2013), explain the key points of the proposals for directives.

The Foreign Agricultural Service of the United States Mission to the European Union also provides an overview of the new Commission’s proposals on its webpage animal cloning .

Regarding the topic of cloning of animals, the European Food Safety Authority (EFSA) devotes a webpage on FAQ on cloning . EFSA’s role in the area of food and feed safety is to carry out risk assessment and provide objective scientific advice to support such decisions.

In the same way, national food safety authorities, ministries and scientific institutes provide information and FAQs on cloning of animals. For instance:

The Roslin Institute (where Dolly the sheep was created ) devotes a webpage on FAQs of cloning .

The Food Safety Authority of Ireland: FAQs animal cloning . Last reviewed 1 November 2012.

The Food Standard Agency of the UK: Cloned animals .

Some overviews about several aspects of the cloning:

The regulatory challenge of animal cloning for food: the risks of risk regulation in the European Union / Maria Weimer. EJRR 1, 2010. 9 p.
In this article the author describes and analyses the regulatory developments at EU level concerning the marketing of foods produced from cloned animals. As they are on the verge of commercialisation in countries outside the EU, especially in the United States, foods from cloned animals are likely to reach the European consumers in the foreseeable future. By considering the discussion on animal cloning in the broader context of EU’s regulation of genetically modified organisms and of nanotechnology, the author identifies the legal and political problems of current regulatory options.

Welfare of genetically modified and cloned animals used for food / a report by Dr R. D. Kirkden and Professor D. M. Broom. Compassion in World Farming, 2012. 142 p.
Compassion in World Farming has commissioned this report to objectively explain and discuss current knowledge regarding welfare implications for animals, in particular dams and their offspring during cloning and genetic modification. Farm animals are sentient beings with the ability to express positive and negative emotions, such as happiness and fear. The impact on welfare of any emerging technology must therefore be considered. This report summarises recent experiments and current techniques, and addresses welfare issues such as survival rates and any associated abnormalities produced by cloning and genetic modification.

This report provides an overview of the process of animal cloning and reviews the current scientific knowledge pertaining to genetic anomalies and biomarkers that may be characteristic of cloned animals. Such biomarkers, may be applied for detecting food products derived from cloned animals and their offspring in the food chain.

Animal cloning and transgenesis / Louis-Marie Houdebine, in OECD, Challenges for Agricultural Research , OECD 2011. 28 p.
Two techniques, cloning and transgenesis, offer new possibilities to improve the exploitation of farm animal genomes. Cloning is a way to generate genitors having the same genome as that of their genetic parents. This allows the prolonged use of genitors having a high value genome validated by the properties of their offspring born after sexual reproduction. Transgenesis is a way to introduce known new traits into genitors in only one generation. This implies foreign gene addition to a genome or specific inactivation of endogenous genes. Cloning and transgenesis are thus opposite but complementary techniques.


Ethical aspects of animal cloning for food supply / European Group on Ethics in Science and New Technologies, January 2008. 56 p.
The European Group on Ethics in Science and New Technologies (EGE) expressed doubts that animal cloning for food production purposes can be justified considering the current level of suffering and health problems of surrogate dams and animal clones. The EGE does not see convincing arguments to justify the production of food from clones and their offspring. If in the future food products derived from cloned animals were to be introduced to the European market, the EGE recommends that the requirements in the following topics: food safety, animal welfare and health, traceability and global trade.

European Institutions and other bodies

European Food Safety Authority

EFSA provides scientific advice in order to evaluate the impact of the animal cloning on food safety, animal health and welfare and the environment. EFSA adopted several scientific opinions and statements.

The first scientific opinion was adopted on 15 July 2008: Food Safety, Animal Health and Welfare and Environmental Impact of Animals derived from Cloning by Somatic Cell Nucleus Transfer (SCNT) and their Offspring and Products Obtained from those Animals . EFSA identified animal health and welfare as the main concern arising from animal cloning by cell nucleus transfer (SCNT) technique. EFSA also stated that there are meaningful animal health and welfare troubles for surrogate mothers and clones, than can be more prevalent and serious for conventionally bred animals. To the contrary, EFSA was unable to identify any risk respecting food safety and the environment.

EFSA’s second statement was published on 23 June 2009: Further Advice on the Implications of Animal Cloning (SCNT) . Although this statement included new publications on SCNT, EFSA confirmed that the conclusions and recommendations of the 2008 opinion are still valid. This statement was updated on 17 September 2010: Update on the state of play of animal cloning . The Scientific Committee concluded that, based on a peer reviewed scientific literature available, the conclusions and recommendations of its scientific opinion and statement were still valid.

The latest EFSA’s statement was published on 5 July 2012: Update on the state of play of Animal Health and Welfare and Environmental Impact of Animals derived from SCNT Cloning and their Offspring, and Food Safety of Products Obtained from those Animals . This statement was based on peer reviewed scientific literature published since the EFSA 2010 Statement, information made available to EFSA following a call for data, and discussions with experts in the field of animal cloning. EFSA concluded that no new information has become available “that would lead, at this point in time, to a reconsideration of the conclusions and recommendations related to the food safety, animal health and welfare aspects, and environmental aspects of animal cloning of the 2008 Scientific Opinion and the 2009 and 2010 Statements of EFSA”

Stakeholder views


Compassion in World Farming (UK) “believes the Commission’s proposals need to be supported by all European Governments and should also include a ban on the use of the offspring of clones, and on meat and milk from these animals. Failure to do this risks perpetuating the cruelty of animal cloning”.

Much awaited draft legislation on cloning: too weak to protect consumers and animals . Eurogroup for Animals, 18 December 2013. 2 p.
In this position paper, Eurogroup for Animals welcomes these long awaited proposals which call for a ban on cloning, however as the legislation stands, there are too many gaps which will allow cloning to continue unchecked against the wishes of Europe’s citizens and which will result in cloning physically taking place in the European Union.

EU consumers have little appetite for cloning: BEUC Position Paper / The European Consumer Organisation (BEUC), October 2014. 11 p.
The European Consumer Organisation considers the new Commission’s proposals fall short of EU consumers’ expectations. Whereas the vast majority of Europeans have little appetite for food produced with the use of cloning and would overwhelmingly want food from the offspring of clones to be labelled (83%), the Commission proposals merely suggest a (temporary) ban on the cloning of animals for food supply and on the sale of food from clones in the EU. They do not say a word about food from cloned animals’ offspring and descendants.

Food and the Transatlantic Trade & Investment Partnership (TTIP): BEUC position / BEUC, May 2014. 13 p.

Europeans’ attitudes towards animal cloning: analytical report. Flash Eurobarometer 238 / conducted by the Gallup Organization, upon the request of Directorate General Health and Consumers. Directorate General Communication, October 2008. 105 p. Summary of the report (17 p.)
Some findings. A large majority of EU citizens (81%) said they knew the term animal cloning, and answered correctly that “cloning is making an identical copy of an existing animal” (80%). Faced with several statements regarding the ethics of animal cloning, the vast majority of EU citizens agreed that: the long-term effects of animal cloning on nature were unknown (84%), animal cloning might lead to human cloning (77%), animal cloning was morally wrong (61%) and cloning might decrease the genetic diversity within livestock populations (63%). Eight out of 10 EU citizens (83%) said that special labelling should be required if food products from the offspring of cloned animals become available in the shops.

Case studies and surveys

Public and private preferences for animal cloning policies / Kathleen R. Brooks and Jayson L. Lusk. Journal of Agricultural and Resource Economics 37(3), 2012. 17 p.
Data on individuals’ private shopping choices are often used to draw conclusions about their desires for food policies. The purpose of this paper is to test this often-implicit assumption using data from a nationwide survey about animal cloning. We find that although individuals’ private choices indicate a strong desire to avoid meat and milk from cloned cattle, public choices predict that only 40.29% have a positive WTP for such a ban. The results suggest caution is necessary when inferring public preferences from private choices.

The prospects for acceptance of animal cloning in the European food chain: early insights from an Irish Sentinel Group / Cathal Murphy… (et al.). AgBioForum, 14(2), 2011. 11 p.
The present study canvassed the opinions of expert stakeholders within the Irish arena. Respondents surveyed did not identify animal cloning as an impending food priority issue, and there was little evidence of in-depth awareness regarding the advanced developmental stage of this technology.

Third countries

According to the Commission’s impact assessment and based on the responses received to tue questionnaire on cloning activities, cloning for food production takes place in USA, Canada, Argentina, Brazil and Australia. In Canada the situation on cloning is similar to that in the Union, i.e. food produced from food is considered novel and requires pre-market approval. In the other countries, clones, their progeny and reproductive material are subject to the same regulation as conventional animals regarding the food safety, animal health and welfare. Clones are registered by private companies (USA, Canada and Brazil) but Argentina and Australia report that clones are not registered. The positions of third countries are summarised in Annex III, Paragraph 2 of the impact assessment.


Argentina Biotechnology Annual Report / United States Department of Agriculture, Foreign Agricultural Service, September 2014 2013. 27 p. See chapter 2: Animal Biotechnology (pages 22-27).
Argentina was the first country in Latin America to develop two generations of genetically modified cows capable of producing Human Growth Hormone. The cloned (but also transgenic) calves, Pampa Mansa II, Pampa Mansa III and Pampero, developed by the Biosidus Company, carry a gene that produces human growth hormone in milk. The milk produced by just one cow can meet the demand of the entire country.


Australia Agricultural Biotechnology Annual / United States Department of Agriculture, Foreign Agricultural Service, September 2014. 27 p. See chapter 2: Animal Biotechnology (pages 24-27).
In Australia, the cloning of livestock is currently restricted to small numbers of elite breeding stock, predicted to be less than 100 beef and dairy cattle and a few sheep within a confined research environment. The work is being carried out by public and private research institutions and universities.


Brazil – Agricultural Biotechnology Report / United States Department of Agriculture, Foreign Agricultural Service, November 2014. 18 p. See chapter 2: Animal Biotechnology (pages 14-18).
Brazil has a well developed research system for cloned animals under the national coordination EMBRAPA. Cloning research started in the late 1990s in Brazil, mostly focused on cattle.


Does Internet use affect public perceptions of technologies in livestock production? / Anahita Hosseini Matin, Ellen Goddard. Agricultural and Applied Economics Association Joint Symposium: Social Networks, Social Media and the Economics of Food, May 2014. 33 p.

The U.S. Food and Drug Administration (FDA): Animal cloning and Consumer FAQs .

Animal Biotechnology in the United States: the regulation of animal clones and genetically engineered animals / Larisa Rudenko, in OECD, Challenges for Agricultural Research , OECD 2011. 14 p.
The implementation of genetic engineering in animals is a rapidly developing field. In January 2009, the US FDA issued the final version of its Guidance on the Regulation of Genetically Engineered Animals Containing Heritable Recombinant DNA Constructs. This document clarifies the FDA’s statutory and regulatory authority, and provides recommendations to producers of GE animals to help them meet their obligations and responsibilities under the Federal Food, Drug, and Cosmetic Act.

The US FDA and animal cloning: risk and regulatory approach / Larisa Rudenko, John C. Matheson. Elsevier, Theriogenology 67, 2007. 9 p. This article is available on the website 2WAYS project.
The Food and Drug Administration’s Center for Veterinary Medicine issued a voluntary request to producers of livestock clones not to introduce food from clones or their progeny into commerce until the agency had assessed whether production of cattle, swine, sheep, or goats by somatic cell nuclear transfer posed any unique risks to the animal(s) involved in the process, humans, or other animals by consuming food from those animals, compared with any other assisted reproductive technology currently in use. The article describes the methodology used by the agency to analyse data and draw its conclusions, the plans the agency has proposed to manage any identified risks, and the risk communication approaches the agency has used.

Animal cloning and the FDA: the risk assessment paradigm under public scrutiny / Larisa Rudenko, John C. Matheson and Stephen F. Sundlof. Nature Biotechnology vol. 25, n° 1, 2007. 5 p.
This article shows that the evidence gathered thus far (ultimately to be published in the Draft Risk Assessment on Animal Cloning) indicates that there are no unique risks associated with animal cloning.
