Some people develop a weird allergy to red meat after being bitten by a lone star tick yet find they can still eat pork from a surprising source - certain pigs originally bred for human organ transplants. So-called GalSafe pigs lack a sugar that would trigger immediate rejection of transplanted organs from ordinary pigs. That sugar is the same culprit that causes the meat allergy. Revivicor Inc. isn't a food company but still owns that herd and shares a small supply of meat, for free, with allergy patients who apply for it.
