Genetically altered American meat may become a reality

As the commercialization of gene-edited pork, specifically PRRS-resistant pork, approaches in 2026, the agricultural industry is poised for a significant shift. This new development, made possible by the Nobel Prize-winning technology CRISPR, carries considerable safety, ethical, and consumer acceptance implications.

Safety evaluations are a priority, with gene-edited products undergoing regulatory review, such as the USDA’s conditional licensure process. The precision of gene editing techniques like CRISPR allows for targeted disease resistance traits, like resistance to Porcine Reproductive and Respiratory Syndrome (PRRS). By reducing the need for antibiotics and improving animal welfare, these edits could potentially address a pressing issue in the industry, where efforts to control the spread of PRRS cost the pork industry an estimated $1.2bn (£878m) annually in the US alone.

However, the debate around unintended consequences and long-term ecosystem impacts continues, underscoring the importance of rigorous safety assessments. The changes in genetically enhanced pigs are surprisingly minimal, primarily targeting a small section of pig DNA related to the CD163 protein. The edit removes only a specific bead from the CD163 protein, which doesn't affect its other functions such as helping dispose of damaged red blood cells.

Ethically, gene-edited animals raise questions about animal welfare improvements versus concerns over genetic manipulation, corporate control over livestock genetics, and implications for biodiversity. While editing PRRS resistance could reduce animal suffering caused by disease, critics argue about the moral limits of genetic alteration and call for transparency and strict governance. The ethical discourse also involves consumer rights to know and choose, influencing labeling policies and corporate practices.

Consumer acceptance remains a key hurdle. While some consumers see benefits in sustainability and animal health, others have ethical or safety concerns that reduce their willingness to buy gene-edited meat. Early marketing for PRRS-resistant pork emphasizes improvements to animal welfare, reduced antibiotic use, and positive environmental impacts. Acceptance may improve with transparent communication, labeling, regulatory endorsement, and evidence of tangible benefits for health, environment, and animal welfare.

Interestingly, surveys and industry reports indicate that men, urban dwellers, and those with lower-level educational qualifications are more likely to express intent to purchase CRISPR-edited pork. This finding suggests that targeted marketing strategies could play a crucial role in addressing consumer concerns and driving acceptance.

In the US, the US Food and Drug Administration (FDA) has recently approved the farming of a specific kind of genetically enhanced pig, and the first widely consumed gene-edited animals are expected to be PRRS-resistant pigs. However, currently, gene-edited foods can't be sold in the EU.

The Genetic Technology (Precision Breeding) Act provides a basis for breeding of gene-edited food in England (but not the wider UK). Meanwhile, the FDA has also approved so-called SLICK cattle, cows with an edit based on a natural gene variant for shorter hair and greater heat resilience in 2022.

Dr Katie Sanders notes that there is a greater potential for consumer acceptance of gene-edited food compared to traditionally genetically modified food, due to being considered more natural. As the commercialization of gene-edited PRRS-resistant pork approaches, it is crucial to address safety, ethical, and consumer considerations to ensure a successful market launch.
