“We can use something that’s not halal if we have to save someone’s life, but the doctor has to decide if the person can be saved any other way," Ahmed Ali, a Sunni imam at the Iqra Masjid in Brooklyn tells The New York Times (NYT). The remarks was on the debate of whether Muslims and Jews are allowed to use pig organs for transplant. For centuries, pigs have been marked as taboo in Judaism and Islam. Both religions describe the animal as unclean and unfit for human consumption. For Jews, pork is treyf—the very opposite of kosher. While pigs have split hooves, they don’t chew cud, disqualifying them under kosher law. For Muslims, pork is haram, forbidden by the Quran alongside carrion and blood, reports NYT.Now, with biotechnology advancing rapidly, genetically modified pigs are being raised to provide organs for human transplantation. This scientific leap promises hope for thousands with organ failure. Yet it also raises a profound question: Can Jews and Muslims accept a pig’s organ to save their lives?Judaism: Preservation of Life Above AllWithin Judaism, the response is surprisingly straightforward. The obligation to save life—pikuach nefesh—overrides nearly every other religious commandment. Scholars and rabbis emphasize that Jewish law allows, and even obligates, using a pig organ if it preserves life.Rabbi Moshe Hauer of the Union of Orthodox Jewish Congregations explains it plainly: “A Jew can do everything from receiving a pig heart valve to playing football with a pigskin.” In other words, the prohibition against pigs applies to eating them, not to life-saving medical use.In this rare case, Jewish opinion is nearly unanimous. While Jews may feel cultural discomfort—the so-called “yuck factor”—the mandate to preserve life leaves little room for debate.Islam: A Higher Bar for AcceptanceIn Islam, the dilemma is more layered. Like Judaism, Islam values the sanctity of life and allows flexibility in dire circumstances. But religious scholars stress two questions: Is there absolute necessity? and Are alternatives available?For kidney failure patients, dialysis exists as an option, though transplants offer better survival and quality of life. This complicates the decision.Islamic bioethicist Dr. Aasim Padela explains that many interpret the Quran to mean the pig itself is corrupt, making its use impermissible unless absolutely necessary. Some Muslim councils have issued fatwas allowing pig organ transplants in life-or-death situations. Still, the hesitation is stronger than in Judaism.The Origins of the Pig TabooWhy pigs? Scholars are still puzzled by the intensity of this prohibition. Archaeological evidence shows pigs were once widely consumed in the Middle East thousands of years ago. But Jewish scriptures in Deuteronomy and Leviticus made the ban absolute, setting Jews apart from neighboring communities.By the first millennium B.C., pork avoidance became a marker of Jewish identity. Later, Islam adopted the same prohibition, reinforcing cultural boundaries. Over centuries, pork avoidance became more than just dietary—it became symbolic, tied to faith, family, and cultural belonging.“Even people who don’t pray or fast avoid pork,” says Rumee Ahmed, an Islamic law professor. “It’s the last frontier.” That ingrained identity makes the thought of a pig organ inside one’s body a deeply unsettling prospect, even if medically permitted.The Emotional and Ethical “Yuck Factor”Beyond doctrine lies the human reaction. A 2023 survey, as reported by the NYT, found that nearly half of Muslim respondents would prefer a transplant from cows or monkeys instead of pigs. Forty percent even said they would rather accept an organ from a dog. Such aversion, experts say, is tied not just to religion but to cultural repugnance.Bioethicist Laurie Zoloth calls it the “moral repugnance factor.” Even when something is legally or religiously allowed, centuries of social conditioning make it feel disturbing. This tension is especially strong for Muslims but present for Jews as well.Personal Struggles with Faith and ScienceFor doctors of faith, the dilemma is personal. Dr. Muhammad Mohiuddin, a Muslim pioneer in xenotransplantation, recalls his father asking him why he chose to work with pigs at all. After years of conversations with Islamic scholars, he concluded pig organs can be used as a last resort, though only after exhausting other medical options.For many believers, the idea of carrying a pig’s heart or kidney inside their body may trigger identity-based unease, even if it means survival.Faith, Flexibility, and the FutureReligions have always adapted when life hangs in the balance. In Judaism, the Sabbath can be broken to save a life, and fasting can be skipped on Yom Kippur if health is at risk. In Islam, exemptions exist for those too ill to fast during Ramadan or pray due to sickness. Both traditions prioritize survival.If clinical trials of pig kidney transplants prove successful, Jewish patients would not only be permitted but obligated to accept them. For Muslims, the acceptance will likely depend on circumstance: a last-resort measure when no alternatives exist.In the end, the dilemma lies less in law and more in emotion. For some, the thought of merging the sacred and the forbidden will always carry discomfort. Yet as medicine advances, faith communities will continue grappling with how ancient taboos fit into the urgent, life-saving choices of modern healthcare.
