The allergy is called alpha-gal syndrome, named for a sugar that’s present in the tissues of nearly all mammals - except for people and some of our primate cousins. It can cause a serious reaction hours after eating beef, pork or any other red meat, or certain mammalian products such as milk or gelatin.David Ayares, president and chief scientific officer of Revivicor, holds a package of frozen meat during an interview at the company’s offices in Blacksburg, Va., on May 30, 2024.

It causes the human immune system to immediately destroy a transplanted organ from an ordinary pig. So the first gene that Revivicor inactivated as it began genetically modifying pigs for animal-to-human transplants was the one that produces alpha-gal.

While xenotransplants still are experimental, Revivicor’swon Food and Drug Administration approval in 2020 to be used as a source of food, and a potential source for human therapeutics. The FDA determined there was no detectable level of alpha-gal across multiple generations of the pigs.

Revivicor, a subsidiary of United Therapeutics, isn’t a food company — it researches xenotransplantation. Nor has it yet found anyone in the agriculture business interested in selling GalSafe pork.

Still, “this is a research pig that FDA approved so let’s get it to the patients,” is how Ayares describes beginning the shipments a few years ago.Experts said getting maternal mortality under control at a national level requires tailoring solutions to individual communities, which is easier when programs are locally run.

New York City has a goal of reducing maternal mortality overall — and specifically achieving a 10% drop in Black maternal mortality by 2030. Statewide, Black residents are about four times more likely to die from pregnancy or childbirth than white residents.Dr. Jacob Lenz performs an ultrasound at the Oklahoma State University obstetrics and gynecology clinic in Tulsa, Okla.

The New Family Home Visits Initiative gives pregnant people and those who’ve given birth visits from professionals such as nurses, midwives, doulas and lactation consultants. Vasan said more than 12,000 families have gotten visits since 2022.
