The legislation to allow gene editing technology to be used commercially in England has passed into law. The Genetic Technology (Precision Breeding) Act received royal assent on 23rd March 2023. This provides for a streamlined regulatory system for precision-breeding techniques. More onerous regulations will remain in place for genetically modified organisms (GMOs). Gene editing ‘switches on and off’ genetic coding which is already present in an organism, whereas GMOs include genetic material introduced from a separate organism.
The new rules will initially apply to plant breeding, before being rolled-out later to farm animals if proved successful. The legislation only applies to England with Scotland, Wales and Northern Ireland still to approve the commercial use of gene editing.
It will be some time before farmers are growing gene-edited crops however. Secondary legislation is needed to implement the new rules, with estimates that this could take two years. Also, the Food Standards Agency (FSA) will need to approve any products produced from gene-edited crops before they can be placed on the market. Defra’s estimate is that it may be five years before crops are ready to be grown commercially.
