Cannibalism is specifically outlawed in only one U.S. state — Idaho — and there is no federal statute criminalizing the act itself. So is cannibalism illegal in the US as a general matter? Functionally, yes. The acts required to obtain human flesh, from homicide to mutilating a corpse, are serious crimes in every state, which makes the practice effectively illegal nationwide even where no statute names it.
No Federal Law Against Eating Human Flesh
Congress has never passed a law making cannibalism a crime. Federal criminal statutes generally reach conduct that crosses state lines, affects interstate commerce, or occurs on federal property, and the isolated act of eating human flesh doesn’t fit any of those categories.
The federal regulatory system doesn’t contemplate it either. The USDA’s Food Safety and Inspection Service regulates meat from “amenable species” under the Federal Meat Inspection Act — cattle, sheep, swine, goats, and domestic poultry. Human tissue isn’t on that list, and it isn’t on the FDA’s separate list of regulated game meats. No federal agency has a process for approving human flesh as food.1U.S. Food and Drug Administration.

Idaho Is the Only State That Bans Cannibalism by Name
Idaho Code § 18-5003 makes it a felony for anyone to willfully eat the flesh or blood of another human being. The punishment is up to 14 years in state prison.2Idaho State Legislature. Idaho Code Section 18-5003 – Cannibalism Defined — Punishment
The statute carves out one affirmative defense: a person who acted “under extreme life-threatening conditions as the only apparent means of survival.” The burden sits with the accused to prove those conditions at trial. Outside that narrow scenario, any willful consumption of human flesh or blood is a felony, with no other element required.2Idaho State Legislature.

In the other 49 states, no equivalent statute exists. Taken in isolation, the act of eating human flesh is not a criminal offense. But that isolation is almost impossible to achieve in real life.
Why It’s Effectively Illegal in Every Other State
The reason the gap doesn’t matter is that every realistic way of obtaining human flesh is itself a crime. Prosecutors don’t need a cannibalism charge when the surrounding conduct already carries years or decades in prison.
Homicide
Killing a person to eat them is murder. A planned killing for that purpose would meet the definition of premeditated first-degree murder in most states, with penalties up to life imprisonment or death. An unplanned killing falls under second-degree murder or voluntary manslaughter, both of which carry lengthy prison terms.
Consent does not change the result. A person cannot legally consent to being killed in any U.S. jurisdiction. You can agree to some contact — a boxing match, a tattoo — but not to conduct creating a substantial risk of death or serious bodily harm. Someone who kills a willing participant still faces homicide charges.
Assault and Battery
If the person survives, cutting flesh from a living body for consumption is aggravated assault or aggravated battery. Both are serious felonies in every state. The same consent limitation applies: courts have consistently held that a person cannot consent to serious bodily harm, so a victim’s agreement doesn’t shield the person who inflicted it.
Corpse Desecration
Even without a killing or an assault — a body found after a natural death, say — laws on the treatment of human remains block the path. Every state criminalizes abuse, desecration, or improper handling of a corpse in some form. The specifics vary, but mutilating, dismembering, or otherwise mistreating remains is prohibited across the board, and cutting up a body for consumption fits squarely within those statutes.
Penalties range from misdemeanors to felonies, with felony-level violations carrying several years in prison and fines that can reach $10,000 or more. Disturbing a grave or stealing a body is a separate offense, usually a felony. Together these laws close off the scenario where someone might claim to have obtained human flesh without hurting anyone.
Consent and Wills Don’t Create a Loophole
A common follow-up: what if someone donates their body for this purpose in a will? The legal system doesn’t allow it. Courts have long been skeptical of testamentary directions for body disposition that conflict with public policy, and consuming a donated body would still violate corpse desecration statutes regardless of the donor’s wishes.
Anatomical gift laws add their own barrier. Every state has adopted some version of the Uniform Anatomical Gift Act, which limits donations to specific purposes: transplantation, therapy, medical education, and research. Consumption isn’t on that list, and no legitimate donation program would accept or facilitate such a bequest. A will directing that your body be eaten would almost certainly be treated as unenforceable on public policy grounds.
Survival Situations
Idaho’s statute explicitly allows a survival defense. In the other 49 states, the question is different because eating flesh isn’t the thing being prosecuted — the surrounding conduct is.
The leading legal treatment of survival cannibalism is the 1884 English case of Dudley and Stephens, in which two shipwrecked sailors killed and ate a dying cabin boy after weeks adrift. The court convicted them of murder and rejected the necessity defense, establishing a principle still influential in common law countries: necessity does not justify intentional killing, even to prevent starvation.
In practice, prosecutions for survival cannibalism are extraordinarily rare. When the person consumed was already dead and wasn’t killed for that purpose, the calculus shifts considerably. Survivors of the 1972 Andes flight disaster, for example, were never prosecuted. Prosecutors have wide discretion, and charging someone who ate flesh to survive otherwise certain death is a case most offices would decline to bring. Idaho’s statute formalizes what is already the practical reality elsewhere.
Self-Cannibalism Sits in a Legal Void
One genuinely unresolved corner of the law is eating your own tissue. If a surgeon amputates your foot and you take it home, no other person has been harmed and no one else’s remains have been desecrated. In the 49 states without a cannibalism statute, there is no obvious criminal charge to bring. The flesh is yours, you obtained it legally, and corpse desecration statutes don’t apply to living tissue removed from your own body.
Idaho’s statute could in theory reach this conduct, because it prohibits willfully ingesting “the flesh or blood of a human being” without limiting the provision to another person’s flesh. Whether a prosecutor would actually bring such a charge is a different question, and there is no reported case testing it.
How Cannibalism Cases Actually Get Charged
When cannibalism surfaces in the criminal justice system, prosecutors don’t need a cannibalism statute. They stack the charges that fit. Jeffrey Dahmer was convicted of multiple counts of murder and abuse of corpses in Wisconsin and received 16 consecutive life sentences. The cannibalism was part of the factual record and likely influenced sentencing, but it was not a separate charge.
That pattern holds across every known U.S. case. The act of eating flesh is almost always accompanied by far more serious crimes carrying far heavier penalties. Prosecutors charge the homicide, the assault, or the corpse desecration, and the cannibalism becomes an aggravating factor rather than a standalone offense. The absence of a specific cannibalism law in 49 states has never prevented anyone from being prosecuted and imprisoned for conduct that included eating human flesh.
