Why It Is Wrong to Promote Alpha‐Gal Syndrome: A Response to Crutchfield and Hereth

Crutchfield and Hereth have proposed the deliberate promotion of tick-borne alpha-gal syndrome (AGS)-a condition typically causing red meat allergy-as a strategy to reduce meat consumption and hence animal suffering. While we share their concern for the ethical treatment of nonhuman animals, we argue that their proposal is morally indefensible and counterproductive. First, we challenge the empirical assumption that inducing AGS would reduce overall animal suffering. Evidence suggests that most people who avoid red meat increase their intake of poultry and fish, leading to a net increase in animal suffering as well as the number of animals killed. Second, we argue that intentionally infecting humans with AGS would violate fundamental moral rights, particularly the right against bodily interference, and that analogies to vaccination are misleading. Unlike vaccination, AGS confers no health benefit, imposes lifelong risks, and would be introduced through a method that is disproportionally coercive. Third, from a virtue-ethical perspective, the proposal fails to promote good moral character. Avoiding red meat due to fear of allergic reactions reflects self-interest rather than moral virtue and, as an instance of moral paternalism, risks provoking psychological reactance and moral resistance. Consequently, Crutchfield and Hereth's "Convergence Argument" for the claim that promoting AGS is morally obligatory collapses. Efforts to reduce meat-eating must instead rely on education, persuasion, and structural reform that respect human rights while fostering genuine moral virtue.
