GalSafe pig is an animal biotechnology product developed for food and biomedical purposes that recently received approval from the US FDA. It was developed by intentional genomic alteration (IGA) i.e. genetic engineering of domestic pigs. The IGA was used to eliminate alpha-gal, a type of sugars found in mammalian cell surfaces, which causes allergic reactions in people with AGS or Alpha-gal Syndrome. �These pigs are to be used for production of heparin, a blood thinning drug.
