Is Beef Lung Safe for Humans? Regulations, Nutrition, and Culinary Uses
Historically, humans have embraced 'nose-to-tail' eating, utilizing all parts of an animal for nourishment and to prevent waste. Beef lung, or 'lights' as it's sometimes called, falls into this category of organ meats or 'offal'. While its place on the modern dinner table has waned in certain cultures, it remains a traditional food source in many parts of the world. The primary concerns surrounding its safety are often more about historical regulatory decisions and cultural norms than actual toxicity.
The Reason for Bans in Some Countries
In some countries, most notably the United States, the sale of beef lung for human consumption is prohibited, but not the act of eating it itself. This ban is rooted in a 1971 USDA rule (9 CFR 310.16(a)) that designated livestock lungs as 'unfit for human food' based on a 1969 study. The study found contaminants like inhaled dust, pollen, and even some stomach contents within the airways of some lungs. However, this ruling has been criticized by experts, including Dr. Jonathan Reisman, a medical doctor and author who petitioned the USDA to reconsider the ban in 2023. Reisman and others point out that humans ingest similar airborne particles all the time and that the ban was not based on any proven health risk, but rather on what was considered a cosmetic or aesthetic concern at the time.
Nutritional Profile of Beef Lung
For those in regions where it is available, beef lung is a nutritionally dense food. It is a source of high-quality protein and contains a range of vitamins and minerals.
- Protein: Beef lung is exceptionally high in protein, which is vital for building and repairing tissues.
- Iron: It is a potent source of iron, with a significant percentage of the daily value in a single serving.
- Vitamins: Beef lung provides several essential vitamins, including C, B12, and niacin.
- Minerals: It also contains important minerals like selenium, copper, and zinc.
Culinary Applications Around the World
Beef lung's light, spongy texture allows it to absorb flavors exceptionally well, making it a versatile ingredient in many cuisines. Proper cooking, typically braising or slow-cooking, is key to making the texture tender and palatable. Some common dishes include:
- Haggis: The famous Scottish dish traditionally uses the lung, heart, and liver of a sheep, although importing haggis containing lung is restricted in the US.
- Peruvian Chanfanita: A dish featuring diced cow lung, or bofe, cooked with potatoes and a flavorful chili paste.

How to Prepare Beef Lung Safely
If you live in a region where beef lung is legally available for human consumption and have sourced it from a reputable butcher, proper preparation is key to ensuring safety and palatability. Always choose fresh, healthy-looking lungs and cook them thoroughly. Given its spongy texture, thorough rinsing and slow cooking are highly recommended.
- Sourcing: Obtain beef lung from a trusted local butcher who can confirm the animal's health and the sourcing regulations.
- Cleaning: Rinse the lung thoroughly under cold water. Some chefs recommend soaking it in water or a brining solution to help draw out impurities, though its porous nature makes this a challenging process.
- Trimming: Trim away any tough connective tissues or large airways. The texture will be best if the lung is cut into small, even-sized pieces.
- Cooking: Slow-cooking methods like braising or simmering are ideal for tenderizing the meat. Bring the lung to a boil, then reduce the heat and let it simmer for an extended period, similar to cooking other tough cuts of meat.
Conclusion
Ultimately, the question of whether beef lung is safe for humans depends heavily on geographical location and local food safety regulations. While the sale of this organ is restricted in some areas, the reasons are often based on historic aesthetic and handling concerns rather than a legitimate risk of toxicity. Nutritionally, it is a valuable source of protein, vitamins, and minerals. For those with access to it, and with proper preparation, beef lung can be a safe and enriching addition to a culinary tradition of nose-to-tail eating.
