A recently unearthed study has set off a tidal wave of outrage after scientists claimed it was 'morally' justifiable to infect people with a virus making them allergic to meat. Researchers Parker Crutchfield and Blake Hereth from Western Michigan University published an inflammatory paper in 2025, making the case that society had a moral 'duty' to spread ticks that were infected with or engineered to carry alpha-gal syndrome (AGS). AGS is a real medical condition transmitted to humans through tick bites, causing victims to suffer allergic reactions when eating red meat, including beef, pork and lamb, dairy and other products derived from mammals.

A recently unearthed study has set off a tidal wave of outrage after scientists claimed it was 'morally' justifiable to infect people with a virus making them allergic to meat.

Researchers Parker Crutchfield and Blake Hereth from Western Michigan University published an inflammatory paper in 2025, making the case that society had a moral 'duty' to spread ticks that were infected with or engineered to carry alpha-gal syndrome (AGS). AGS is a real medical condition transmitted to humans through tick bites, causing victims to suffer allergic reactions when eating red meat, including beef, pork and lamb, dairy and other products derived from mammals.

The symptoms can range from a mild case of hives or stomach pain to severe and even life-threatening cases of anaphylaxis - where blood pressure suddenly drops and the person becomes unable to breathe as their airways swell up. Crutchfield and Hereth claimed that it was morally wrong to eat meat because of the suffering animals endure and the environmental damage that the meat industry allegedly causes.

They argued that the only reason society should not be spreading ticks to infect people with AGS today is that scientists do not currently have an easy and effective way to do it on a large scale. However, they added: 'But it is feasible to genetically edit the disease-carrying capacity of ticks. If we are right, then today we have the obligation to research and develop the capacity to proliferate tickborne AGS and, tomorrow, carry out that proliferation.

' One critic of the study replied: 'Isn't this biological terrorism? Shouldn't they be thrown in jail?

' Scientists argued that the only reason society should not be spreading ticks to infect people with AGS today is that scientists do not currently have an easy and effective way to do it on a large scale Alpha-gal syndrome is a real medical condition transmitted to humans through tick bites, causing victims to suffer allergic reactions when eating red meat, including beef, pork and lamb, dairy and other products derived from mammals. The study authors did not conduct any medical experiments or new research to back up their claims, calling their paper a work of philosophy, using ethical reasoning from different moral theories and assuming that meat-eating is bad.

Their main findings were that promoting genetically modified ticks to spread AGS would make the world better and help people become more 'virtuous' by avoiding meat. They also claimed that this process would not violate anyone's rights, despite proposing to intentionally infect the population with a life-threatening infection. AGS is triggered by a bite from the lone star tick, a breed of the parasite found throughout the US from Texas to the East Coast.

When a tick bites someone, it injects alpha-gal sugar into the person's body, causing the immune system to develop antibodies that attack it. Between 2017 and 2022, the CDC reported about 90,000 suspected cases of AGS, and the number of new suspected cases increased by approximately 15,000 each year. The agency has estimated that as many as half a million Americans have AGS. It can also complicate medical treatments involving mammal-based ingredients in certain medications, vaccines or surgical materials.

There is currently no cure, and the tick-transmitted illness requires lifelong avoidance of meat-based products.

'Intentionally inflicting a debilitating disease on people is a horribly vicious crime and should get the strongest possible penalty,' another person added on social media. The Western Michigan University Homer Stryker MD School of Medicine defended the paper, published in the journal Bioethics, calling the researcher's conclusions 'a thought experiment.

' In a statement to the fact-checking website Snopes, the school wrote: 'Thought experiments are a long-established and legitimate philosophical method. ' 'Their purpose is to examine the implications of ethical commitments and to surface hidden assumptions so they can be scrutinized. They are neither policy proposals nor clinical recommendations.

' However, the reaction from the public has been fierce, with critics blasting the authors for claiming that meat eaters should be infected with a disease to prevent them from eating meat. 'Anyone who works to spread alpha-gal should be tried for crimes against humanity,' one commenter on X said
