In a landmark decision that has sparked both excitement and concern, UK ministers have given the green light for farmers to begin growing gene-edited crops in England and Wales. However, in a surprising twist, they have postponed extending this authorization to the creation of gene-edited animals, a move that has left many scientists feeling frustrated and dismayed.
Gene editing, a cutting-edge technology that allows for precise changes to be made to plant or animal DNA, has been heralded as a game-changer in the world of agriculture. Proponents argue that it could lead to the development of hardier, healthier crops and livestock that are better equipped to withstand the challenges posed by climate change and disease outbreaks.
The Precision Breeding Act: A Step Forward or a Missed Opportunity?
The decision to approve gene editing for crops comes in the wake of the Genetic Technology (Precision Breeding) Act, which was passed by the previous government. However, the implementation of this law required secondary legislation, which was not passed before the general election, leaving the future of gene editing in the UK in limbo.
While the current government has now committed to passing this secondary legislation for plants and derived food and feed products, they have remained silent on the issue of gene-edited animals. This lack of action has drawn sharp criticism from scientists working in the field of animal health and welfare.
“This could have a detrimental impact on the research landscape in this country,” warned Professor John Hammond, director of research at the Pirbright Institute. “In an age of climate change and other threats, we need to be able to make the best use of technologies like gene editing to improve the lives of animals.”

The Looming Threat of Animal Diseases
The urgency of the situation has been underscored by recent outbreaks of devastating animal diseases across the globe. In Spain, a virulent strain of porcine reproductive and respiratory syndrome has been wiping out entire pig herds, while African swine fever continues its relentless march northward through Europe.
Even more alarmingly, bird flu virus has been detected in both dairy cattle and their milk in the United States, raising fears of a potential public health crisis. In light of these mounting threats, many experts believe that every available tool, including precision breeding, must be leveraged to protect the health and welfare of both animals and humans.
“With a virulent strain of porcine reproductive and respiratory syndrome wiping out pig herds in Spain, African swine fever on the march north through Europe, and bird flu virus detected in both dairy cattle and their milk in the US, the importance of enabling all potential solutions as soon as possible, including precision breeding, cannot be overstated.”

Balancing Innovation and Ethics
Despite the potential benefits of gene editing in animals, the decision to delay its implementation has been welcomed by some animal welfare groups. The RSPCA, for example, has argued that pushing animal productivity even further through genetic modification is unethical, given the amount of food waste that already occurs.
While acknowledging that there may be some merit to using gene editing to create disease-resistant animal breeds, the organization maintains that such measures should be seen as a last resort, with a focus instead on improving housing, husbandry, and veterinary care to prevent illness in the first place.
“Directly editing animal genomes should be seen as a last resort. And what happens if a gene edit proves to be unstable? How will this be detected, and how will these animals be safeguarded and brought back into conditions where they can be properly monitored?”

The Future of Gene Editing in the UK
As the debate over gene editing in animals continues to rage, there are concerns that the UK risks falling behind other countries in this critical area of research. Many scientists fear that if British researchers are prevented from developing gene-edited animal breeds, the country could lose valuable expertise, investment, and talent to nations with more permissive regulatory environments.
Despite these challenges, there is cause for optimism in the world of crop gene editing. With the government’s approval, farmers and researchers can now begin exploring the vast potential of this technology to create more resilient, sustainable, and productive plants.
As the UK navigates this complex landscape of innovation, ethics, and public opinion, it will be crucial to strike a balance between harnessing the power of gene editing to address pressing global challenges and ensuring that the welfare of both animals and humans remains at the forefront of the conversation.
