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.

In India, more than one in four people has hypertension, and cumulatively, over 90 per cent of adults with hypertension are either undiagnosed, untreated, or treated but still live with uncontrolled blood pressure. Experts say this growing burden needs urgent attention.
In an interview with HealthandMe on World Hypertension Day 2026, Professor Vivekanand Jha, Executive Director of The George Institute for Global Health, suggested that one practical solution may be as simple as switching to potassium-enriched low-sodium salt substitutes (LSSS).
Current estimates show that Indians consume between 8 and 11 grams of salt (equivalent to 3.2–4.4 grams of sodium) per day — nearly double the World Health Organization recommended limit of 5 grams of salt (2 grams of sodium).
Low-sodium salt substitutes are composed of approximately 70–75 per cent sodium chloride and 25–30 per cent potassium chloride. They reduce sodium intake while increasing potassium consumption, helping lower blood pressure and reduce cardiovascular risk.
In January 2025, the World Health Organization released guidelines recommending potassium-enriched salt substitutes to combat hypertension and related heart risks. The guidelines suggest replacing regular table salt, which is high in sodium, with potassium-enriched alternatives that may help reduce noncommunicable diseases such as cardiovascular disease and chronic kidney disease by lowering blood pressure.
Dr Jha was also part of a consensus statement released by experts in clinical medicine, public health, and nutrition, recommending potassium-enriched low-sodium salt substitutes as an effective intervention to reduce hypertension and cardiovascular disease in India.
Here are excerpts from the interview:
Q. Is asking people to simply switch to a healthier salt more realistic than expecting them to completely change their diets?
Dr Jha: Public health works best when solutions fit naturally into people’s daily lives. Asking families to completely change what they eat is extremely difficult because food habits are emotional, cultural, and built over generations. But asking them to switch the type of salt they use at home is a much simpler and more achievable step. The taste remains familiar, cooking habits do not change, and yet the health benefits can begin immediately.
In a country like India, where a large proportion of sodium intake comes from salt added during cooking, this becomes a very practical intervention. It is not about perfection — it is about finding solutions that ordinary families can realistically adopt and sustain. There are, of course, other dietary factors that also need attention, such as excessive sugar intake, processed foods, and poor fruit consumption.
Q. High blood pressure medicines are often prescribed quickly. Are doctors giving enough importance to simple dietary changes like switching to healthier salt, or is prevention still underestimated?
Dr Jha: The answer is a definite no.
Our healthcare system is designed around managing disease once it appears, rather than reducing people’s need to come to hospitals by preventing disease in the first place.

In a busy clinic, physicians often have only a few minutes with each patient, making detailed dietary counselling difficult. At the same time, advice like “eat less salt” can feel abstract or impractical for many patients. There are also systemic incentives that prioritize medicines over preventive care.
We need much stronger integration of nutrition and prevention into routine medical practice. If we truly want to reduce the burden of hypertension and its complications — including cardiovascular disease, stroke, and chronic kidney disease — prevention cannot remain an afterthought.
Q. Low-sodium salt may not suit some people with kidney disease or those on certain medicines. How can these risks be managed without discouraging the wider population from benefiting?
Dr Jha: This is an important conversation and needs to be handled responsibly and transparently. There is a small group of patients — particularly some people with advanced kidney disease or those on specific medications — for whom excess potassium may not be appropriate.
However, for the vast majority of the population, including many people with early-stage kidney disease, low-sodium salt substitutes are safe and beneficial. We have repeatedly shown this through modelling studies.
The challenge is ensuring that a legitimate caution for one group does not unintentionally discourage everyone else. That is why clear labelling, better awareness among healthcare professionals, and honest public communication are essential. Public health decisions are often about balancing risks and benefits, and in this case, the potential population-level benefits are very significant, including for a large majority of patients with chronic kidney disease.

Q. Emerging evidence suggests increasing potassium may be as important as reducing sodium. Does this change how India should approach hypertension prevention?
Dr Jha: This is a very important point and broadens the conversation in a meaningful way. As it turns out, many physicians are also unaware that potassium intake among Indians is substantially lower than recommended, and that increasing potassium intake can help lower blood pressure and improve cardiovascular health.
What makes low-sodium salt substitutes particularly valuable is that they address both issues together — they reduce sodium while increasing potassium through a product people already use every day. This dual benefit could make a meaningful difference at scale.
It does not replace the need for healthier diets overall, but it does provide a practical and scalable public health tool.

Prime Minister Narendra Modi has recently urged Indian households to reduce their cooking oil consumption by at least 10 per cent.
While the appeal is part of a broader strategy to decrease India’s heavy reliance on imports, which currently accounts for 65 per cent of its edible oil needs, and comes amid the escalating Iran-US war, health experts said that this should become the norm in the country, burdened with chronic diseases.
High consumption of edible oils, particularly those high in saturated and trans fats like palm oil, is strongly linked to a higher risk of non-communicable diseases (NCDs) such as cardiovascular diseases, obesity, type 2 diabetes, and certain cancers.
These NCDs are also the leading cause of mortality in India, accounting for approximately 63–66 per cent of all deaths.
“Prime Minister Narendra Modi’s appeal to reduce oil consumption is not just a temporary health message, but a lifestyle habit every Indian family should adopt permanently. Excessive oil intake has become one of the major contributors to rising obesity, diabetes, hypertension, and heart disease cases in India, especially among younger populations,” Dr. Arvind Dambalkar, Senior Consultant & Head – Interventional Cardiology, Sarvodaya Hospital, Faridabad, told HealthandMe.
Dr. Madhu Nahar Roy, Director, Internal Medicine - Paras Health Udaipur, added that the message on reducing oil consumption is timely, especially as lifestyle diseases continue to rise across India.
PM Modi first urged Indians to reduce cooking oil consumption by 10 per cent during his 79th Independence Day address, highlighting the need to tackle the rapidly rising burden of obesity and lifestyle diseases in India.
"In the coming years, obesity can become a major challenge for our country," the Prime Minister said. "If every family decides to reduce the use of cooking oil by 10 per cent, it will benefit the health of the nation."

Again, in April, on World Health Day, he reiterated that adopting healthier eating habits, such as reducing oil usage, is “not just a personal decision but a social responsibility”.
He called for immediate action to prevent such a scenario and proposed a simple change: "I want to take a promise from you today that we all should reduce our cooking oil by 10 per cent. This will be a big step towards reducing obesity."
India now ranks second globally in the number of overweight and obese children, according to the World Obesity Atlas.
If current trends continue, nearly 56 million children in the country could be affected by 2040.
As per the International Diabetes Federation’s Diabetes Atlas, India has 89.8 million adults diagnosed with diabetes, with projections suggesting that number will grow to a massive 156.7 million in 2050.
Further, in India, more than 1 in 4 people have hypertension, and cumulatively, more than 90 per cent of adults with hypertension are either undiagnosed, untreated, or treated but live with uncontrolled hypertension.
At the same time, cardiovascular disease (CVD) is the leading cause of mortality in India, accounting for nearly 28 per cent of all deaths and 45 per cent of NCD deaths.

Dr. Arvind noted that fried and processed foods increase unhealthy fat accumulation, disturb cholesterol levels, and put long-term stress on the heart.
“A family of four should limit edible oil consumption to around 3 to 4 liters per month, as recommended by health experts. Choosing balanced, home-cooked meals with controlled oil can significantly improve overall Cardiac Health,” he said.
The expert noted that refined oils are not inherently harmful, but excessive consumption and repeated reheating can increase unhealthy fat intake and inflammation.
“For Indian cooking, mustard oil is beneficial for traditional high-heat cooking due to its good fatty acid profile, olive oil works well for salads and light sautéing, while sunflower oil should be used in moderation and rotated with other oils,” Dr. Madhu told HealthandMe.
The expert also stated that adopting healthier cooking methods, such as air frying, steaming, roasting, and grilling, can help reduce excess calorie and fat consumption significantly.

Dozens of food products, including chocolates, snack mixes, popcorn, chips, and nuts, have been recalled in the US over the risk of salmonella contamination.
The recall is due to a specific ingredient — milk powder supplied by California Dairies — used in several products and snacks, particularly in seasonings.
According to the Food and Drug Administration (FDA), the potentially tainted powdered milk and buttermilk were voluntarily recalled on April 20.

The FDA urges people who purchased the products to throw them away or return them for a refund.
A separate Salmonella recall impacting 12 flavors of the popular chocolate brand Spring & Mulberry was also recently announced by the FDA, but appeared to be linked to a date supplier. It wasn't immediately clear if there was any connection to the California Dairies recall.
Another is a public health alert issued by the US Department of Agriculture’s Food Safety and Inspection Service (FSIS) for headcheese over possible contamination with Listeria monocytogenes (Lm).

As per the US Food and Drug Administration (FDA), Salmonella is a group of bacteria that can cause gastrointestinal illness and fever called salmonellosis. It can be spread by food handlers who do not wash their hands and/or the surfaces and tools they use between food preparation steps. It can also happen when people consume uncooked and raw food. Salmonella can also spread from animals to people.
The FDA notes that people who have direct contact with certain animals, including poultry and reptiles, can spread the bacteria from the animal to food if hand washing hygiene is not practiced.
Pets, too, could spread the bacteria within the home environment if they eat food contaminated with Salmonella.
Common symptoms of Salmonella include
Children younger than 5, adults 65 and older, and people with weakened immune systems are more likely to have severe illness.
