Is Raw Milk Worth The Risk? Truth About Raw Milk And Its Potential For Contamination
Raw milk, long debated as healthier and nutritious than pasteurized milk by enthusiasts but strongly cautioned against by health practitioners, is now a hot topic in health and wellness circles with the increasing popularity of "natural" and "unprocessed" foods. The dangers surrounding raw milk have been brought to the forefront with the outbreak of H5N1 bird flu, highlighting the risk of contamination in raw milk supplies. All about raw milk, its risks, and the latest science.
Raw milk is unpasteurized milk taken directly from cows, goats, or other similar animals. Unpasteurized milk does not go through the heat treatment process meant to destroy harmful pathogens and bacteria. Raw milk proponents say that pasteurization kills nutrients and enzymes. And that might be one false claim after another, as science continues to disprove it.
According to Dr. Meghan Davis of Johns Hopkins Bloomberg School of Public Health, pasteurization does not significantly alter the concentration of minerals or the quality of proteins in milk. In fact, it's a critical step to ensure food safety, particularly for animal-derived products prone to contamination.
Wellness influencers have in recent times advocated for raw milk as the "clean" and "natural" alternative to commercial milk distributed in stores, using claims from improved digestion to the stimulation of the immune system. However, these claims are not scientifically proven. Although raw milk contains antibodies, the amounts are too small to be worth anything for health.
Raw milk consumption poses immense risks. It can become contaminated in two major ways:
1. Internal Contamination: Pathogens such as E. coli, Salmonella, and Campylobacter can seep into milk through infected animals.
2. External Contamination: Polluted water, dirt, manure, and contaminated equipment introduce harmful microorganisms.
The infections acquired from raw milk include diarrhea, stomach cramps, nausea, and fever, and severe effects can be experienced by infants, the elderly, pregnant women, and even immunocompromised people. Some other rare but serious diseases like hemolytic uremic syndrome, which may bring about renal failure or stroke, have also been associated with raw milk.
Raw milk has become a focal point of the latest bird flu outbreak as preliminary genetic analysis indicates the H5N1 virus, which causes avian flu, may have begun infecting cattle earlier than thought. And the CDC says viral particles have been found in raw milk, which adds one more risk to consuming unpasteurized dairy.
A notable case was with sick and dead cats on a Texas dairy farm that resulted from ingesting unpasteurized milk from infected cows. This presents how unpasteurized milk can be a vector for transmitting diseases.
To reduce the risk, the FDA prohibited the interstate sale of unpasteurized milk in the United States. Different states, however, have their respective regulations on this matter:
- 20 states completely banned the sale of unpasteurized milk.
- 30 states allow raw milk sales under specified conditions.
Although these laws exist for protection of public health, many consumers are not even aware of the dangers associated with their consumption.
Pasteurization destroys harmful bacteria without affecting the nutritional content of milk. Several studies in *Nutrition Today* report that pasteurization does not change the nutrient profile of milk. Pasteurized milk is free from pathogens and, therefore, also a safer alternative for all consumers, especially vulnerable ones.
It's not just raw milk that's hazardous. Cheese, yogurt, and ice cream with unpasteurized milk carry the same dangers. To anyone tempted by the supposed health value of raw dairy, experts say in one voice: stick to pasteurized, and avoid illnesses like bird flu or salmonella infection.
Health organizations, including the FDA, CDC, and American Academy of Pediatrics, strongly advise against consuming raw milk. Beyond the personal health risks, drinking raw milk can also endanger others by increasing the spread of harmful bacteria and viruses.
The emergence of H5N1 in cattle and its link to raw milk calls the world to wake up to better preparedness. Like COVID-19, bird flu has demonstrated vulnerabilities in our food safety systems. The presence of avian flu in raw milk underscores the imperative for strict rules, public education, and investments in the prevention of these diseases.
Could this outbreak push governments and health organizations to step up surveillance and vaccination efforts against zoonotic diseases? The lessons learned from COVID-19 suggest a coordinated approach is essential to prevent future pandemics.
On the other hand, raw milk is far riskier and has far fewer benefits than its apparent healthy, "natural" choice. From bacterial contamination to the allowance of viruses like H5N1, there is evidence that is clear: pasteurization cannot be wished away. As we face new health challenges, it will be science over trends that safeguard public health.

Amid intensified inspections and market surveillance by the Food Safety and Standards Authority of India (FSSAI) to crack down on counterfeit and substandard dairy products, a new survey has found that 6 in 10 urban Indian households are not fully confident about the purity and quality of the ghee or clarified butter they consume.
The survey, conducted by community social media platform LocalCircles, received over 91,000 responses from more than 18,000 urban consumers across 293 districts, revealing widespread concern over adulteration—particularly in loose and unbranded ghee.
According to the survey:
The findings come amid a series of enforcement actions by FSSAI targeting fake and substandard dairy products across India.

In December 2025, FSSAI directed all States and Union Territories to launch a nationwide enforcement drive against the adulteration and misbranding of milk and milk products, including ghee, paneer and khoya, under the Food Safety and Standards Act, 2006.
Since then, the regulator has significantly expanded inspections and surveillance. Recent enforcement actions include:
FSSAI has also issued notices to quick-commerce platforms over complaints of expired and spoiled food products being delivered to consumers.
Made by clarifying butter obtained from cow's milk, ghee is a staple in Indian kitchens and contains approximately 130 calories and 15 grams of fat per tablespoon. It is also a rich source of vitamins A, D, E and K, along with antioxidants.
However, because ghee is high in saturated fat, excessive consumption may raise LDL ("bad") cholesterol levels in some individuals and increase the risk of cardiovascular disease.

Health experts advise people with certain medical conditions to consume ghee cautiously or avoid it altogether.
These include people with:
Doctors generally recommend limiting intake to no more than two teaspoons a day, unless advised otherwise by a healthcare professional.
Food adulteration involves the deliberate addition of inferior or harmful substances to food products, compromising their quality and safety.
According to a 2024 study published in SAGE Open Medicine, consuming adulterated food may increase the risk of:
The study notes that children, pregnant women and older adults are particularly vulnerable to the harmful effects of adulterated food.

India has approved its first plant-based Vitamin D3 (cholecalciferol) ingredient, a move that could expand options for food fortification and dietary supplements while addressing the country's widespread Vitamin D deficiency.
The Food Safety and Standards Authority of India (FSSAI) has cleared VITADEE Green, developed by Fermenta Biotech,for use in health supplements, nutraceuticals and food products.
The company stated that the ingredient is produced using an India-patented process and offers a sustainable, scalable and vegetarian-friendly source of Vitamin D3.
The approval allows Indian manufacturers to incorporate the ingredient into fortified foods, beverages and dietary supplements.
It is particularly significant for vegetarians and vegans, who have traditionally had limited access to Vitamin D3 because most supplements are derived from lanolin, a by-product of sheep's wool.
The approval also supports India's broader efforts to improve nutrition through food fortification, an area where experts say Vitamin D remains a major gap.
Studies suggest a large proportion of Indians have inadequate Vitamin D levels despite abundant sunlight, largely due to urban lifestyles, limited outdoor exposure and reduced sun exposure.
"Vitamin D deficiency remains a widespread public health concern in India, and the demand for sustainable nutrition continues to grow rapidly. The FSSAI approval allows us to bring VITADEE Green directly to Indian food fortification and nutraceutical manufacturers, helping bridge the nutrition gap for the country's large population," said Prashant Nagre, Managing Director, Fermenta Biotech.
For India's large vegetarian population, the approval also brings a domestically manufactured, regulatory-approved plant-source Vitamin D3 to the market.
Vitamin D3, often called the "sunshine vitamin," is produced by the body when the skin is exposed to sunlight.
It helps the body absorb calcium, maintain healthy bones and teeth, and lowers the risk of fractures. In children, severe deficiency can lead to rickets, while in adults it increases the risk of osteoporosis, muscle weakness and falls.
Beyond bone health, Vitamin D3 also supports immune function. Research suggests low Vitamin D levels may be associated with increased susceptibility to infections and higher levels of inflammation.
Despite abundant sunshine, Vitamin D deficiency is common across India. Experts attribute this to long hours spent indoors, limited outdoor activity, sunscreen use, ageing and diets naturally low in Vitamin D.
Low Vitamin D levels can lead to weak bones, muscle weakness and an increased risk of fractures. In children, severe deficiency can cause rickets, while inadequate levels have also been linked to poorer immune function.
"Vitamin D deficiency remains a widespread public health concern in India, and the demand for sustainable nutrition continues to grow rapidly," said Prashant Nagre, Managing Director of Fermenta Biotech.
Doctors say no—not in terms of effectiveness.
Dr. Murtaza S. Bagwala, Head of Emergency Medical Services at Saifee Hospital, Mumbai, told HealthandMe that current evidence shows plant-based Vitamin D3 raises Vitamin D levels just as effectively as conventional supplements.
"Based on current science, plant-based Vitamin D3 is comparable to conventional Vitamin D3 supplements. For most people, it is a good alternative if they prefer a plant-based product," he said.
Dr. Sudhir Kumar, Neurologist at Apollo Hospitals, Hyderabad, explained that plant-derived Vitamin D3—typically sourced from lichen, algae or newer fermentation technologies—offers an animal-free option without compromising efficacy.
"It is good news for consumers who prefer vegan products, but both forms are equally effective. There is no medical reason for people to switch if they are already taking conventional Vitamin D3," he said in a post on X.
The experts said the key question is whether supplementation is needed, not whether the source is plant- or animal-derived.
"The source matters mainly for ethical, dietary or personal preference—not for efficacy," Dr. Sudhir said.
Dr. Bagwala cautioned against taking high-dose Vitamin D without medical advice, as excessive intake can raise calcium levels and increase the risk of kidney stones and other complications.
Doctors recommend that supplementation should be based on:

One extra serving of leafy greens like kale and spinach may be good for your lungs and help you breathe better, according to a study. The secret? It is the vitamin K1 found in leafy green vegetables.
Researchers from Edith Cowan University (ECU) tracked more than 179,000 adults over a decade and found that people who eat more vitamin K1-rich foods such as leafy green vegetables may lower their risk of chronic lung disease and boost lung function.
“We found that people who ate more vitamin K1-rich green vegetables had better lung function and were less likely to develop COPD,” ECU researcher Chengfeng Li said.
“Just one extra serve of leafy greens like kale, about one and a half to two cups a day, is an achievable way to boost your vitamin K1 intake,” Li added.
The findings suggest that adding more greens to your plate could help keep your lungs in better shape as you age.
The study found that those with the highest intake of vitamin K1 had about a 16 per cent lower risk of COPD compared to those eating the least.
They also had better lung performance, meaning their lungs could hold and move more air, a key sign of good respiratory health.
“Vitamin K likely activates a protein that protects the lungs’ elastic fibers - the tiny structures that let your lungs expand and contract,” Associate Professor Marc Sim said.
“When these fibers break down, breathing becomes harder over time. This nutrient may help keep lung tissue flexible and prevent damage,” Sim added.

The second type, vitamin K2, showed no benefit for COPD risk, though it was linked to somewhat better lung function at moderate intakes.
The researchers think the same protective mechanism probably applies to vitamin K2, but any benefit may be masked by what it's eaten alongside.
K1-rich leafy greens, by contrast, come with their own bonus nutrients like fiber and antioxidants that may boost the effect, while K2's main sources, including processed and red meat, are linked to poorer health outcomes.
The study also found no link between vitamin K and asthma, suggesting vitamin K may be more relevant for long-term lung damage rather than allergic conditions.
While the boost from greens appears favorable, researchers are clear on one thing: it won’t cancel out smoking.
“The biggest thing you can do for your lungs is to quit smoking and reduce your exposure to environmental pollution,” Li said.
“But a healthy diet may still play a supporting role by counteracting some of the damage caused by these harmful factors.”
“Eating more leafy greens is a simple step that could help support lung health over time.”

The World Health Organization data shows that chronic obstructive pulmonary disease (COPD) remains the fourth leading cause of death worldwide. The condition was responsible for an estimated 3.5 million deaths in 2021, according to the latest available global data.
COPD is a common and serious lung disease, and the WHO noted that smoking, indoor and outdoor pollution, and harmful inhalants are among its most significant triggers.
If your breathing feels effortless, steady, and natural, so much so that you barely notice it, your lungs are likely in good shape. To maintain this good lung health, it is essential to:
