The Food and Drug Administration (FDA) has approved genetically modified pigs for use in τρόφιμα and medically products. Τα ζώα αναπτύχθηκαν από την ιατρική εταιρεία Revivicor, και θα μπορούσαν να χρησιμοποιηθούν για την παραγωγή φαρμάκων, για την παροχή οργάνων και ιστών για μεταμοσχεύσεις και για την παραγωγή κρέατος που είναι ασφαλές για κατανάλωση από άτομα με αλλεργίες στο κρέας.
"Today's first approval of an animal bio producttechnology both for food and as a potential source of biomedical use represents a huge milestone for scientific innovation," said FDA Commissioner Stephen M. Hahn in a press release.
Pigs are called GalSafe pigs because they do not have a molecule called alpha-gal sugar, which can cause allergic reactions. Alpha-gal sugar is found in many mammals, but usually not in humans. Alpha-gal syndrome (AGS), which causes severe meat allergies, can occur after being bitten by a deer tick. Although not specifically tested for people with AGS, the FDA has determined that GalSafe pork products are safe for the general population.
In addition to their potential for safer consumption, there are many potential medical uses for GalSafe pigs. They could be used to make drugs such as heparin, a common blood thinner derived from animal tissue. Animals could also be useful in organ transplants, as alpha-gal sugar can cause the body to not accept an organ. The animals have not yet been tested for transplantation, so further research is required.
This is not the first time the FDA has approved genetically modified animals. In 2009, the FDA approved genetically modified goats that produce a drug in their milk to prevent blood clots. Chickens that can produce medicine in their eggs were approved in 2015, the same year salmon became the first genetically modified animal approved for consumption. But GalSafe pigs mark the first time the FDA has approved a genetically modified animal for human consumption but also for medical use.
Any biological programmer wishing to use GalSafe pigs should seek further approval from the FDA.
