The arrival of gene editing tools has led the world to a point in time when dozens if not hundreds of new food products will soon be available. They will be added to products already out there which are genetically modified.


In 2020 in the U.S., ‘GalSafe’ pigs joined salmon as the only GMOs approved for human consumption. The US Food and Drug Administration (FDA) approved the use of these pigs in the production of drugs, to provide organs and tissues for human transplant, and to produce meat for people with meat allergies.


Avoiding castration


Gene editing also provides a way to avoid castration, an animal welfare issue that has received a large amount of attention in recent years.


Consumer study


A new study from Iowa State University (ISU) has been released, the first to gauge public acceptance in that country of gene edited foods using a nationally representative sample of 2,000 US residents. It is part of the Gene Edited Foods Project, which is currently working on a set of recommendations for governance tools and strategies to address gaps in public trust.


As described in the news release, the survey will be repeated every 2 years for the next decade to track how public attitudes on gene edited foods shift as more products come onto the market.


  “Our study shows that when you have a new technology that people are not familiar with, other factors play a much bigger role, especially people’s social and ethical values, and whether they trust government and industry to protect them.”
