Let’s be real for a second. You probably clicked on this because you saw a weird post on social media or stumbled onto a dark corner of a forum claiming that the government allows a "certain percentage" of human remains in your burgers or hot dogs. It sounds like the plot of a bad horror movie.
Honestly? It's a terrifying thought.
But if you’re looking for a number—like 0.1% or some specific "allowable limit"—I’ll give you the short answer right now: Zero. There is absolutely no amount of human meat allowed in food produced for commercial consumption. None. Not in the US, not in the EU, not anywhere with a functioning food safety agency.
The idea that there’s a legal threshold for "human material" is one of those persistent urban legends that refuses to die, mostly because people confuse actual FDA "defect levels" for things like insect fragments with some sort of dystopian allowance for cannibalism. It doesn't work that way.
The FDA "Defect Action Levels" and the Source of the Myth
You’ve probably heard people talk about how many rat hairs are allowed in peanut butter. That part is actually true. The FDA has a document called the Food Defect Levels Handbook. It outlines the maximum levels of "natural or unavoidable defects" in foods that present no health hazards to humans. We’re talking about things like mold, insect parts, or rodent hairs that get swept up during massive industrial harvests.
But here is the thing.
Human DNA or human tissue is never listed. Why? Because human remains are not considered an "unavoidable" byproduct of the harvesting or manufacturing process. If human remains were found in a food processing plant, it wouldn't be a "defect level" issue. It would be a crime scene.
When a worker is unfortunately injured or killed in a manufacturing plant—which does happen in the industrial food world—the protocol isn't to just keep the belt moving. Under OSHA and USDA regulations, the entire production line is halted. Any product that could have potentially been contaminated is destroyed.

The financial loss to the company is massive, but the legal and PR risk of letting contaminated product hit the shelves is even bigger. No corporation is "slipping" human meat into the supply chain to save a buck; the litigation alone would bankrupt them.
Why Human Meat in the Food Supply is a Public Health Nightmare
Forget the ethics for a moment. Let’s look at the biology. From a purely clinical perspective, human meat is incredibly dangerous for other humans to eat.
You’ve likely heard of Mad Cow Disease (BSE). In humans, the equivalent is something called Kuru or Creutzfeldt-Jakob Disease (CJD). These are caused by prions—misfolded proteins that essentially turn your brain into a sponge. Prions aren't like bacteria or viruses; you can't just "cook them out." They are heat-resistant.
Historical studies of the Fore people in Papua New Guinea, conducted by researchers like Michael Alpers and Carleton Gajdusek, showed that funeral cannibalism led to a massive outbreak of Kuru. Because of this, the medical community and global food regulators like the World Health Organization (WHO) view human tissue as a high-risk biohazard.
The Legal Reality of Cannibalism
Is it actually "illegal" to eat human meat? This is where things get kinda weirdly specific.
In the United States, there is actually no federal law specifically banning the act of cannibalism itself. However, nearly every state has laws against the desecration of a corpse. Then you have murder, obviously. You also have laws regarding the necropsy and disposal of human remains.
If you are a commercial food producer, you fall under the Federal Meat Inspection Act (FMIA). The FMIA is incredibly strict about what species can be slaughtered for food. Humans are not on that list. If it’s not on the list, it cannot be sold as food. Period.

What about that "Human Meat Burger" you saw online?
Every few years, a story goes viral about a restaurant serving human flesh. In 2014, a satirical website claimed a "human meat factory" was found in Thailand. In 2017, a fake story about a London restaurant called "The Resurrection Restaurant" made the rounds.
They were all hoaxes.
There was also a famous PR stunt by a vegan brand that created a "human meat burger" made entirely of plant-based ingredients (soy, mushrooms, and wheat gluten) to see if they could replicate the supposed taste and texture. It was a marketing gimmick. No actual humans were harmed.
The Ethical and "Lab-Grown" Loophole
As we move into 2026, the conversation is shifting toward cultivated meat (lab-grown meat). Technically, a scientist could take a biopsy of human cells and grow them in a bioreactor.
In 2020, a group of designers created the Ouroboros Steak, a DIY kit for growing steaks from your own cells. It wasn't a commercial product; it was a "provocative art piece" intended to critique the meat industry.
Even if someone wanted to sell "lab-grown human meat," it would never pass regulatory hurdles. The FDA and USDA have a joint framework for cell-cultured meat, and they require rigorous safety testing. Given the prion risks and the obvious "ick factor" that would lead to massive public outcry, no regulator is going to sign off on that. It’s a non-starter.
Real Examples of Accidental Contamination
While "human meat" isn't an ingredient, DNA contamination is a real thing in the food industry. But we are talking about microscopic levels—like a flake of skin or a hair.

A study published in PLOS ONE by researchers at Clear Labs once analyzed 254 burgers. They found "human DNA" in a small percentage of them.
Does that mean there was human meat in the burger? No.
It means a worker likely handled the sample without gloves, or a hair fell into the grinder. In the world of high-sensitivity genomic testing, you can find human DNA on almost any surface that people touch. It's a far cry from the "Soylent Green" scenarios people worry about.
How to Verify Food Safety for Yourself
If you're genuinely worried about what's in your food, looking for "human meat" is probably the wrong thing to focus on. You should be looking at traceability.
- Check the USDA Establishment Number: Every meat product has a circle with "U.S. Inspected and Passed by Department of Agriculture" and a number. You can look this number up on the USDA website to see the facility's safety record.
- Third-Party Audits: Look for labels like SQF (Safe Quality Food) or BRCGS. These indicate the facility goes above and beyond government baselines.
- Recall Lists: Check FoodSafety.gov regularly. If there is ever a contamination event—biological or otherwise—it’s listed there immediately.
The food supply chain is complicated. It's messy. But it's also governed by a level of bureaucracy that makes the intentional or "allowed" inclusion of human tissue impossible.
The "allowable limit" is zero, and it’s going to stay that way. The next time you see a headline claiming otherwise, remember that clickbait thrives on your disgust, but the law thrives on strict, boring, and very non-human ingredient lists.
Actionable Steps for the Concerned Consumer
- Stop following "shook" content creators who cite the FDA Defect Handbook without actually reading it. The handbook covers bugs and mold, not people.
- Focus on "Whole Muscle" cuts if you are worried about mystery meat. It’s impossible to "hide" anything in a ribeye steak compared to a finely ground hot dog or nugget.
- Support local butchers. If you can see the carcass and the person cutting it, you have 100% transparency into the source.
- Report suspicious labeling. If you ever find something in your food that doesn't belong, don't just throw it away. Save the packaging and the "foreign object" and contact your state's Department of Agriculture or the FDA’s Consumer Complaint Coordinator.
