Government has launched consultation to change current strict EU rules

Gene editing of crops and livestock may soon be permitted in England for the first time under a consultation launched by the government on Thursday.

 

Ministers said changing the current strict rules, which originate from the EU and make gene editing for crops and livestock almost impossible, would bring widespread benefits to consumers and farmers, including healthier food, environmental improvements and better animal welfare.

 

But some environmental and animal welfare groups raised concerns that loosening the rules could lead to lower animal welfare, for instance if the technology was used to promote faster growth over animal health, or to enable livestock to be kept in crowded conditions.

 

Gene editing involves cutting and splicing sections of DNA within a single genome to bring about changes that were previously possible only through lengthy selective breeding of plants and animals. This is a different process from genetic modification, which involves introducing DNA from one species into another, and which will continue to be subject to a near-total ban.

 

George Eustice, the secretary of state for environment, food and rural affairs, said: “Gene editing has the ability to harness the genetic resources that mother nature has provided, in order to tackle the challenges of our age. This includes breeding crops that perform better, reducing costs to farmers and impacts on the environment, and helping us all adapt to the challenges of climate change.”

 

Through gene editing, crops could be developed that require fewer pesticides or fertilisers, or which have enhanced nutritional properties. For instance, tomatoes that can lower blood pressure have recently been licensed for sale in Japan. Animal genes could also be edited in ways that would allow the breeding of livestock that was resistant to key diseases, which would reduce the need for antibiotics and so the likelihood of developing resistant superbugs.

 

However, Peter Stevenson, chief policy adviser at the campaigning group Compassion in World Farming, said the ways in which livestock had been bred for profitable traits in the past suggested the development of gene editing would be harmful to animals. He pointed to genetic selection for broiler chickens, whereby the fast growth rates gave rise to leg abnormalities and lameness, and in laying hens, selecting for high egg production caused osteoporosis, leaving the hens vulnerable to bone fractures.

 

Breeding animals resistant to diseases would only encourage farmers to stock them more intensively, he added, leading to overcrowding and lower animal welfare. “This is pushing us down the industrial farming route,” he warned. “It is entrenching an antiquated system of farming that we would do better to abandon.”
