Why Pasture-Raised Pork Matters: A Farm’s Perspective on Sustainability, Nutrition, and Quality

At Meadowlark Farm, raising our Kunekune pigs on pasture is more than just a method — it’s a commitment to doing what’s right for the environment, the animals, and the people who enjoy our pork. In today’s world, where much of the pork supply comes from large-scale Concentrated Animal Feeding Operations (CAFOs), it’s essential to understand why pasture-raised pork matters — and how it makes a difference in so many ways.
The Real Costs of CAFO Pork: Health and Environmental Harm You Can’t Ignore
Concentrated Animal Feeding Operations (CAFOs), where thousands of pigs are confined indoors with little room to move, might seem efficient and cost-effective on paper. But behind the scenes, these operations create serious harm — not only to the animals but to workers, neighbors, and the environment.
Water Pollution:
CAFOs produce massive amounts of manure that can contaminate nearby water sources through nutrient runoff, especially nitrogen and phosphorus, which cause harmful algal blooms and oxygen-depleted “dead zones.” Manure also carries pathogens and pharmaceutical residues, including antibiotics, which pose risks to human health and contribute to antibiotic resistance in the environment. Effective manure management and stricter regulations are essential to reduce these serious impacts on water quality and public health. Impacts of waste from CAFO’s on water quality
Air Pollution:
Airborne emissions from CAFOs include ammonia, hydrogen sulfide, particulate matter, and a mix of volatile organic compounds (VOCs). These pollutants don’t stay contained — they drift into nearby communities. According to a comprehensive review in International Journal of Environmental Research and Public Health, exposure to these airborne contaminants causes severe, chronic health problems for people living close by, not just mild irritation:
Respiratory diseases: Long-term exposure increases the risk of asthma, chronic bronchitis, and other obstructive pulmonary diseases. These conditions can lead to lifelong lung damage, reduced lung function, and increased mortality.
Neurological and cardiovascular effects: Some airborne compounds from CAFOs are linked to systemic inflammation and cardiovascular stress, worsening overall health.
Mental health impacts: Stress and anxiety related to odors and health fears are also significant issues for residents.
Worker Health Risks:
The people working inside CAFOs face some of the worst exposures. They inhale high levels of dust, gases, and microbial pathogens daily. This is not just temporary discomfort — workers suffer long-term and potentially irreversible damage such as:
Chronic respiratory illnesses, including occupational asthma and chronic bronchitis
Increased risk of zoonotic infections (diseases that jump from animals to humans)
Musculoskeletal injuries due to repetitive and strenuous labor
Psychological stress caused by harsh working conditions
Antibiotic Use and Resistance:
To control disease in such crowded and stressful environments, pigs in CAFOs are routinely given antibiotics, often at sub-therapeutic levels. This practice promotes the development of antibiotic-resistant bacteria that can spread to workers, communities, and consumers through air, water, and food. These resistant infections are harder to treat and represent a growing global health threat.
Soil and Climate Impact:
The CAFO model depends on synthetic fertilizers and monoculture feed crops, which degrade soil biodiversity and organic matter. These systems release significant methane and nitrous oxide — greenhouse gases far more potent than CO₂ — contributing heavily to climate change. In contrast, regenerative grazing builds soil health and helps sequester carbon.
Bottom line: CAFOs don’t just create minor nuisances like headaches or coughs — the science shows they cause serious, long-lasting health problems for workers and communities, contaminate vital water resources, pollute the air, contribute to antibiotic resistance, and accelerate climate change.
In contrast, pasture-raising pigs creates a regenerative cycle. Our Kunekunes roam and forage in rotating pastures, naturally aerating the soil and cycling nutrients. This rotation allows grasses and other plants to recover, builds organic matter, supports beneficial soil microbes, and helps sequester carbon. We deserve better than a system that sacrifices public health and the environment for cheap meat. Regenerative farming offers a path forward — one that respects animal welfare, supports worker and community health, and restores the land.
Nutritional Superiority of Pasture-Raised Pork
Pigs raised on pasture eat a much more diverse diet — grasses, roots, insects, and naturally supplemented feeds — compared to the grain-heavy rations typical of confined animal feeding operations (CAFOs). This diversity directly improves the nutrient profile of their meat and fat:
Higher Omega-3 Fatty Acids:
Pasture-raised pork contains significantly more omega-3s than conventional pork. These essential fats reduce inflammation and support heart and brain health. Yet more than two-thirds of U.S. adults and 95% of children are deficient in omega-3s, a shortfall linked to higher cardiovascular risk and sudden cardiac death (Omega Fatty Acids and Cardiovascular Disease).More Conjugated Linoleic Acid (CLA):
CLA is a naturally occurring fatty acid linked to anti-inflammatory and anti-cancer properties (CLA Effects in Humans). Forage access can dramatically increase CLA content in pork fat compared to grain-fed systems (Grain Vs Forage-Fed Pork).Richer in Fat-Soluble Vitamins:
Outdoor access allows pigs to synthesize high amounts of vitamin D from sunlight, which is stored in their fat and meat — something impossible in windowless CAFO barns. Pasture diets also increase vitamins A and E, antioxidants that support immune function and skin health (Improving Meat by Enhancing Soil & Sun Exposure Increases Nutrition of Pork).
In conventional systems, pigs fed predominantly corn and soy have higher omega-6 fatty acids, which can promote inflammation when consumed by humans.
Taste and Quality That Reflects Care
Beyond health and environment, pasture-raised pork offers a superior culinary experience:
Flavor Depth: The slower growth rate of heritage breeds like Kunekunes and their varied diet produce meat with richer, more complex flavors.
Tenderness and Juiciness: The natural marbling and healthy fat composition contribute to a juicy texture that conventional pork, often produced for speed and uniformity, can’t match.
Clean Eating: Without additives, excessive water retention, or artificial enhancers, pasture-raised pork delivers a pure and satisfying eating experience.

Supporting a Sustainable and Ethical Food System
Choosing pasture-raised pork supports more than just your own health and taste buds — it helps sustain family farms, promotes animal welfare, and encourages environmentally responsible agriculture. Farms like ours invest in soil health, care deeply for our animals, and provide transparency you won’t find in industrial meat production.
In Conclusion
Pasture-raised pork from heritage breeds like Kunekunes is an investment in a healthier planet, a more nutritious diet, and a tastier meal. At Meadowlark Farm, we’re proud to raise pigs with integrity and invite you to taste the difference that care, pasture, and time make.
