High meat is raw meat that has been intentionally left to decompose in a sealed container for weeks or months, then eaten. Practitioners claim the rotting process creates beneficial bacteria and produces a feeling of euphoria or mental clarity, which is where the name “high” comes from. The practice exists on the fringes of raw food communities and has no scientific support for its purported benefits. It carries serious, well-documented health risks.
How High Meat Is Made
The basic process involves placing chunks of raw meat (usually beef, bison, or chicken) into a glass jar with a lid. The jar is stored at cool temperatures, sometimes in a refrigerator, sometimes in a cooler. Every few days, the lid is opened briefly to introduce fresh oxygen, then resealed. This “airing” step is considered essential by practitioners, who believe it encourages aerobic bacteria over the anaerobic bacteria responsible for the most dangerous toxins.
The meat sits for anywhere from several weeks to several months. Over time, it changes color, develops a strong odor, and takes on a slimy texture. Practitioners typically consume small portions at a time, often holding their nose due to the smell. The concept was popularized by Aajonus Vonderplanitz, a raw food advocate who promoted the idea that decomposed animal products could restore gut health and improve mood. Vonderplanitz had no medical or scientific credentials supporting these claims.
Why People Claim It Produces a “High”
The most common claim is that bacteria in the decomposing meat produce compounds that affect brain chemistry, leading to euphoria, elevated mood, or a sense of mental sharpness. No controlled study has ever tested this claim or identified a plausible mechanism specific to rotting meat.
What decomposing meat does reliably produce are biogenic amines: chemicals created when bacteria break down amino acids in protein. These include histamine, tyramine, putrescine, cadaverine, and phenylethylamine. Putrescine and cadaverine accumulate as meat spoils and are actually used as scientific indicators of spoilage. Phenylethylamine is structurally related to amphetamine and can raise blood pressure, particularly when combined with tyramine. It’s possible that some of the reported “high” sensation comes from these compounds acting on the nervous system, but this would be a form of mild intoxication, not a health benefit.
The mood effects people describe could also be a placebo response, an adrenaline reaction to eating something the body recognizes as dangerous, or the physiological effects of biogenic amines that happen to feel pleasant before they cause harm.
What Biogenic Amines Actually Do to Your Body
The biogenic amines that build up in decomposing meat are not benign. High exposure is associated with nausea, headaches, heart palpitations, respiratory distress, sweating, diarrhea, and dangerous changes in blood pressure. Histamine in spoiled protein-rich foods causes a condition called scombroid poisoning, typically seen with fish, which produces flushing of the face and neck, oral numbness, hives, and difficulty swallowing. Symptoms usually develop within a few hours of eating.
Tyramine triggers what’s known as the “cheese reaction,” originally identified in aged cheese: migraine, rapid heart rate, elevated blood sugar, and a spike in blood pressure that can be dangerous for people on certain medications. Phenylethylamine, when present alongside tyramine, amplifies migraine risk and blood pressure increases. The body has enzymes that can break down small amounts of these amines, but when the quantity overwhelms that system, food intoxication results.
The Pathogen Problem
Decomposing raw meat is an ideal environment for dangerous bacteria. The pathogens most associated with meat include Salmonella, E. coli, Listeria, Campylobacter, Staphylococcus aureus, Clostridium perfringens, and Clostridium botulinum. Staphylococcus aureus produces heat-stable toxins that cause food poisoning even if food is later cooked. Clostridium species thrive in low-oxygen environments, which is exactly what a sealed jar provides between airings.
Clostridium botulinum is the most concerning. It produces one of the most potent toxins known to science, causing botulism, a potentially fatal illness that paralyzes muscles, including those used for breathing. The USDA’s food safety guidelines for commercially fermented meat products require specific pH levels (at or below 5.3 to control staph growth), precise salt concentrations (10% brine to prevent toxin production), and the use of sodium nitrite or carefully controlled water activity to prevent C. botulinum growth. High meat involves none of these safeguards. There is no starter culture controlling fermentation, no salt cure, no pH monitoring, and no nitrite.
Real-World Cases of Fermented Meat Gone Wrong
Traditional fermented meat practices exist in several cultures, most notably among Inuit communities in the Arctic. These are not the same as high meat, but they illustrate the risks even when a community has generations of experience with the process. Kiviak, a traditional Greenlandic food, involves packing up to 500 whole seabirds into a sewn seal skin, sealing it with rendered fat, burying it under rocks, and fermenting it for three months. The process is highly specific: the seal fat creates an anaerobic seal that repels flies, and the particular bird species matters.
In 2013, several people in Siorapaluk, Greenland, died after eating kiviak made from eider ducks instead of the traditional little auks. The substitution changed the fermentation dynamics, and the consumers developed botulism. The polar explorer Knud Rasmussen’s death has also been attributed to food poisoning from kiviak. In the United States, CDC surveillance data from 2021 recorded botulism outbreaks linked to fermented beluga whale in Alaska (two cases), home-prepared seal oil (two cases), and fermented fish heads buried in the ground (a traditional preparation known as “stink heads”). These outbreaks involved type E botulinum toxin, which is specifically associated with marine and fermented animal products.
These cases involved culturally established methods with some built-in safety knowledge passed down over centuries. High meat, by contrast, is a modern improvisation with no traditional framework and no safety controls.
How Legitimate Meat Fermentation Differs
Safe fermented meat products do exist. Salami, chorizo, and other cured sausages involve controlled fermentation, but the process bears almost no resemblance to high meat. Commercial producers use specific bacterial starter cultures (typically strains of Lactobacillus) that rapidly lower pH, creating an acidic environment hostile to dangerous pathogens. Salt concentrations are carefully calibrated. Sodium nitrite is added at precise levels, around 50 parts per million, specifically to prevent C. botulinum growth. Temperature and humidity are monitored throughout fermentation and drying.
The USDA requires that ready-to-eat fermented meat products achieve at least a 100,000-fold reduction in Salmonella and a 1,000-fold reduction in Listeria. These are rigorous, measurable standards enforced through inspection. The fermentation in these products enhances protein digestibility by breaking polypeptides into amino acids, and the lactic acid bacteria involved have documented probiotic properties. But none of this applies to raw meat left to rot in a jar at home without starter cultures, salt, nitrite, or any form of process control.
The Bottom Line on Safety
High meat is not a fermented food in any meaningful sense. Fermentation implies a controlled microbial process that preserves food and makes it safer. What happens in a jar of high meat is uncontrolled decomposition, where whatever bacteria are present on the raw meat multiply freely. The result is a product loaded with biogenic amines at unpredictable concentrations and potentially harboring some of the most dangerous foodborne pathogens known. The euphoria some people report is not evidence of a health benefit. It is more likely a physiological response to bioactive amines that, at higher doses, cause illness.
