Determined: No Unique Regulations*

Gene-edited animals that do not contain DNA from another species are regulated as conventional animals, so they don’t face the tighter restrictions of transgenic GMOs.

Gene-edited crops and food are regulated as conventional plants unless they contain foreign DNA, after a dossier is submitted to determine if they are exempt. Changes introduced in January 2018 determined that most NBTs should not be regulated as transgenic GMOs because no genes are inserted from other (e.g. foreign) species. Each product is evaluated on a case-by-case-basis. Regulations focus on the characteristics of the final product, as does the US, rather than the process used to create the product, as is the case in the EU. The government assesses the risk level of each newly developed food or animal, whether new genetic material was introduced and whether the product has already been approved for commercialization in other countries.


  • Hornless cows: In October 2018, the National Technical Biosafety Commission (CTNBio) determined that gene-edited hornless cows (edited using TALENS gene-editing tools) developed in cooperation with the US firm Recombinetics are conventional animals. As of 2019, this project is on hold as researchers develop a new line of hornless cows using CRISPR.
  • Heat tolerant cows: Using TALENS, Minnesota Red Angus cows, whose meat is sold at a premium in Brazil, are being modified to handle the Brazilian heat more easily. Known as Genzel, the cloned cow awaits approval.
  • Tender, marbled cow: Gene sequencing is being used to improve the tenderness and marbling in local Nelore cattle.
  • High-yield tilapia: An application has been submitted to CTNBio for tilapia with higher fillet yield.

Regulatory Timeline

2018: The National Technical Biosafety Commission (CTNBio) released Normative Resolution No. 16, focusing on NBTs. It clarified that many products derived from genetic engineering do not meet the definition of a GMO as defined by the 2005 regulation and determined that NBTs should be regulated on a case-by-case basis.

2018: Brazil and 12 other nations, including Argentina, Australia, Canada and the US, issue a joint statement supporting agricultural applications of precision biotechnology, stating that governments should “avoid arbitrary and unjustifiable distinctions between end products derived from precision biotechnology and similar end products, obtained through other production methods.”

2018: Ministries of Agriculture of the South Agricultural Council (Argentina, Brazil, Chile, Paraguay and Uruguay) publish declaration stating they would avoid arbitrary and unjustifiable distinctions between agricultural products obtained by gene editing and those obtained through other methods, share information about the development of products and regulatory frameworks, explore opportunities for regional and international harmonization, and work together including with other countries to avoid obstacles.

2005: Brazil established the CTNBio under Law No. 11.105 to set rules for laboratories and establish authorization procedures for GMO research, the production and marketing of GMOs, restrictions on their release into the environment, regimes for their cultivation, requirements for reporting their release, inspections and monitoring of GMO research activities and their commercial release, implementing authorities and authorizing procedures for their release, and restrictions on GMOs in foodstuffs. It provided for the punishment of administrative violations and criminal offenses. CTNBio has approved the commercial use of about fifty GMOs, 15 of which are animals.

2003: A decree was issued to regulate the labelling of food and food ingredients intended for human consumption and animal feed when they contain or are produced from GMOs.

1995: Brazil passed Law No. 8.974, which established safety and inspection requirements for genetic engineering in agriculture and humans. The aim of the Act was to protect human, animal and plant health as well as the environment. It established which manipulation methods would be prohibited, including human genetic manipulation.

NGO Reaction

Local farmers and organizations have protested the 2018 CTNBio resolution deciding that NBTs would not be regulated as GMOs. They published an open letter claiming that the resolution would only benefit large agricultural businesses and that it could lead to new transgenic organisms being released, even though it does not include transgenic organisms in the changes.

†Proposed: No Unique Regulations: Decrees under consideration for gene-edited crops that do not incorporate DNA from another species would no require unique regulations beyond current what is imposed on conventional breeding.

Gene editing of plants and food products. Research and development has mostly focused on disease resistance, drought resistance, and increasing yield, but more recent advances have produced low trans-fat oils and high-fiber grains.
Gene editing of animals, not including animal research for human drugs and therapies. Fewer gene edited animals have been developed than gene edited crops, but scientists have developed hornless and heat-tolerant cattle and fast-growing tilapia may soon be the first gene edited animal to be consumed.

Global gene editing regulatory landscape

The regulations on genetically engineered crops and animals are emerging out of the regulatory landscape developed for transgenic GMOs. Regulations across 34 countries where transgenic or gene edited crops and animals are commercially allowed (as of 12/19) are guided in part by two factors:
Whether the country has ratified the international agreement that took effect in 2003 that aims to ensure the safe handling, transport and use of living modified organisms (LMOs) resulting from biotechnology that may impact biological diversity, also taking into account potential risks to human health. It entered into force for those nations that signed it in 2003. It applies the ‘precautionary approach as contained in the Rio Declaration on Environment and Development. The US, Canada, Australia and Chile and the Russian Federation have not signed the treaty.
Whether regulations are based on the genetic process used to create the trait (conventional, mutagenesis, transgenesis, gene editing, etc.) or the final product.Transgenic crops and animals (aka GMOs) are product regulated in many countries including the US and Canada, while the EU, India, China and others regulate based on how the product is made. There is almost an equal number of countries with product- and process-based regulations. It’s not clear how much this distinction matters. It’s somewhat true that countries with product-based regulation have more crops approved and the approval process is more streamlined, but there are contradictions. For example, Brazil and Argentina have emerged as GMO super powers using different regulatory concepts, while there is no GMO commercial cultivation in Japan, North Korea, and the Russian Federation, which employ product-based regulations. How this will effect gene editing regulations is also unclear. For example, Japan, which has no commercialized GMOs, is emerging as a leader in the introduction of gene edited crops.

Gene editing is a set of techniques that can be used to precisely modify the DNA of almost any organism. It is being used for applications in human health, gene drives and agriculture. There are numerous gene-editing tools besides CRISPR-Cas 9, which gets most of the attention because it is a comparatively easy tool to use.

Gene editing does not usually involve transgenics – moving ‘foreign’ genes between species. It also refers to a specific technique in contrast to the general term GMO, which is scientifically ambiguous, as genetic modification is a process not a product. Most gene editing involves creating new products by deleting very small segments of DNA (sometimes in agriculture called Site-Directed Nuclease 1 or SDN-1 techniques), which can silence a gene or change a gene’s activity. Countries are evaluating whether or not to regulate this type of gene editing, since it is so similar to natural mutations. The GLP’s Gene Editing Index ratings reflect the regulatory status of SDN-1 techniques, which are the most liberally regulated and will generate most products in the near term.

To develop different products, gene editing can change larger segments of DNA or add DNA from other species (a form of transgenics sometimes in agriculture called SDN-2 or SDN-3 techniques). While many countries are not regulating or lightly regulating SDN-1 techniques, most are moving toward tightly regulating or even restricting SDN-2 and SDN-3.
