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.

A fit and otherwise healthy man in his fifties has been left without sensation on the entire left side of his body after suffering a stroke linked to his daily energy drink habit. Doctors were puzzled at first because his medical history was clear, yet his blood pressure was extremely high. It was only when he admitted to drinking about eight cans a day that they traced the cause of the clot in his brain.
The case has prompted specialists writing in the BMJ Case Reports journal to push for tighter oversight of energy drinks, which are consumed by more than 1.7 million people in the UK. Concerns about their safety have grown in recent years, especially since some contain more caffeine than several shots of espresso.
Reaching for an energy drink may feel like a quick solution when fatigue sets in, but with rising questions about their health impact, experts are asking people to be careful. A December 2025 case report in BMJ Case Reports described how heavy use of energy drinks may raise the risk of heart disease and stroke.
The man in his fifties arrived at the hospital with extremely high blood pressure. He had weakness on the left side of his body, numbness and trouble with balance, walking, swallowing and speech. Tests confirmed a stroke. His blood pressure dropped with treatment, but once he returned home, it rose again despite being on medication.
Further questioning showed he had been drinking roughly eight energy drinks every day. Each one contained around 160 milligrams of caffeine, far above the recommended daily amount. When he stopped drinking them, his blood pressure settled and he no longer needed medication.
Many energy drinks have high levels of caffeine and sugar, both of which can raise health concerns.
“Too much caffeine can disrupt sleep, worsen insomnia and add to mental health strain,” Dr. Frank Hu, a professor of nutrition and epidemiology at Harvard Medicine School of Public Health, told TODAY.com.
The FDA advises that up to 400 milligrams of caffeine a day is safe for most adults. A single energy drink can reach or exceed that range, Hu said. A small energy shot can contain around 230 milligrams of caffeine, an 8.4-ounce drink can have about 80 milligrams and a 20-ounce can may reach 190 milligrams. People react to caffeine differently, the FDA notes.
Katherine Zeratsky, a registered dietitian nutritionist at Mayo Clinic, said that caffeine on its own may be safe for many, but when it is combined with other stimulants commonly found in energy drinks, the total effect may be too strong for the heart and blood vessels.
“The idea is that caffeine mixed with other ingredients creates a stronger stimulant response that affects heart rate, heart rhythm or blood pressure,” Zeratsky told TODAY.com. “That is what can send someone to the emergency department with a cardiac issue.”
Along with caffeine, Hu and Julia Zumpano, a registered dietitian at the Cleveland Clinic’s Center for Human Nutrition, pointed out another problem in many energy drinks: large amounts of sugar.
“Excess sugar contributes to weight gain, obesity and Type 2 diabetes. Because these drinks offer calories without nutrients, it is very easy to take in more than you realise,” Hu said.
Zumpano noted that this sugar load is especially risky for people with diabetes, obesity, heart disease or high triglycerides, which increase the chance of heart attack and stroke. “These drinks can also play a part in developing those conditions,” she said.
If you need an energy boost, the experts encouraged choosing options that are healthier than energy drinks. But if you still decide to buy one, they suggested checking the label closely. Try to avoid caffeine and sugar levels that exceed daily recommendations and stay cautious of long ingredient lists.
Energy drinks often contain caffeine, sugar, added vitamins and amino acids. Common ingredients include ginseng, guarana, L-carnitine and taurine. Zumpano explained that while these may be considered safe on their own, their combined effect is not well understood.
“Some of these ingredients are familiar, and for others we do not have enough strong research, so they are not recommended if you plan to drink them often,” she said. She advised avoiding drinks with ingredients you do not recognise and choosing those with simpler formulations.

Eggoz, a premium egg-selling company landed in a controversy after a YouTube video went viral claiming that their sample had tested positive for Nitrofuran. This chemical is a broad-spectrum antibiotic, but is banned due to concerns about potential carcinogenicity and persistent residues. Studies have also shows that nitrofuran and its metabolites could cause cancer.
Trustified, a brand that provides laboratory testing shared a video that claimed to have found genotoxic substances in eggs produced by Eggoz Nutrition. This led to questions which were raised on the nutritional value of the eggs sold by the brand.
Arpit Mangal, who runs the social media channel, said that lab tests on eggs sold under the Eggoz brand showed the presence of AOZ, a marker that can signal past exposure to nitrofuran antibiotics during poultry production. He also shared an Instagram reel titled “Real Egg vs ‘Plastic Egg’ Claims – Lab Test Teaser,” telling viewers, “When was the last time you questioned the quality of your eggs? We took a deep dive into Eggoz, a brand everyone knows, and ran a test that’s never been done before. The results left us shocked.”
Dr Sudhir Kumar, senior consultant Neurologist, Apollo Hospital told Times Now, "As of now, we do not need to get concerned, because it is well within the permissible limits, as with this much minute amount, there is no risk of cancer."
Experts say that while AOZ traces could be alarming, one needs to interpret the findings for scientific clarity.
"Eggs definitely have lots of benefits; they are a good source of protein and have vitamins, including B12. So, as of now, people should consume, but just that they should make sure that, yes, they are from a trusted source, and there should definitely be awareness that even good brands can have chemicals,” he added.
AOZ, or 3-amino-2-oxazolidinone, is a metabolite linked to nitrofurans, a class of antibiotics that should not be used in poultry because of their potential to cause cellular and DNA-related damage when consumed in large or long-term doses. Experts clarify that finding trace amounts of AOZ in an isolated sample does not mean eggs are cancer-causing or unsafe for the public. Instead, its presence signals that the parent drug may have been used at some point.
Specialists explain that AOZ binds tightly to animal tissues and can linger long after the original antibiotic has broken down. This is why regulators consider AOZ a red-flag marker indicating previous exposure to nitrofurans rather than a direct toxin in itself.
Scientific studies have linked nitrofurans and their breakdown products to possible carcinogenic and mutagenic effects in animals. These concerns prompted many countries to introduce strict bans on their use in food-producing animals, including poultry, pigs, shrimp, and aquaculture.
Nitrofurans were once popular in farming because they were inexpensive and worked effectively against a wide range of infections. However, they quickly convert into metabolites such as AOZ, AMOZ, AHD, and SEM, which become bound to tissues and can remain detectable for weeks. This persistence makes it difficult for authorities to monitor and prevent illegal use, and it raises concerns about potential long-term health risks for consumers.
Today, regulators in the European Union and several other regions use highly sensitive laboratory tests designed to detect these metabolites directly in products like meat, eggs, honey, and seafood. These tests help identify residues even when the original drug has vanished, ensuring greater oversight and food safety.

Energy Drinks And Stroke Risk: An absolutely fit and healthy man, 54, a runner too, a non-smoker, non-drinker and off the drugs, suffered a stroke that caused permanent damage to him. This is after he consumed energy drinks. It all started when he suddenly noticed a weakness in his left side of the body. It started with numbness and difficulties with balance, walking, swallowing and speech. This is when his family member rushed him to a nearby stroke clinic.
According to CNN: “His blood pressure was sky high, about 254 over 150 millimeters, yet when you looked at him you’ve never know it, because he looked so well. That’s why we call hypertension the silent killer,” said Dr. Sunil Munshi, a consulting physician at Nottingham University Hospitals NHS Trust in the United Kingdom.
The man was a warehouse worker from Sherwood, Nottingham and the case is published in BMJ Case Reports, with Munshi being the senior author of the paper.
As per Dr Munshi, the patient arrived at the hospital with numbness on his left side. Scans revealed a stroke in the thalamus, a deep part of the brain responsible for balance and coordination.
“His left side was numb, and scans showed he had a stroke in the deeper part of the brain, the thalamus, which explains the unsteadiness,” Dr. Munshi said. The man was admitted, and doctors began aggressive treatment. He required five different medications before his blood pressure fell to 170. Normal adult blood pressure is below 120 over 80 millimeters of mercury. Readings of 180 over 120 or higher qualify as a medical crisis.
Once discharged, the situation worsened. At home, his blood pressure rose again, reaching 220 despite continued treatment. With no clear medical cause, doctors conducted extensive tests. Everything came back negative.
The breakthrough came only when the man casually mentioned his daily habit. To stay alert on long shifts, he drank eight highly potent energy drinks every day, two cans at four separate points. Each can contained about 160 milligrams of caffeine.
Study first author Dr. Martha Coyle noted that some energy drinks contain up to 500 milligrams of caffeine per can. For comparison, tea has about 30 milligrams and coffee about 90. In the United Kingdom, adults are advised to consume no more than 400 milligrams of caffeine a day. This man was taking in more than 1,200 milligrams, about triple the recommended limit. The US Food and Drug Administration gives the same advice.
After he stopped drinking energy beverages entirely, his blood pressure returned to normal within weeks. He is healthy today, but the stroke left lasting effects.
“I obviously wasn’t aware of the dangers,” the man told his doctors. “I have been left with numbness on the left side, in my hand, fingers, foot and toes even after eight years.”
Researchers say the problem extends far beyond caffeine. Many energy drinks contain taurine, an amino acid that can raise blood pressure even more when combined with caffeine. High sugar levels also contribute to blood vessel damage.
“These drinks contain combinations of ingredients that increase blood pressure, affect metabolism and may damage blood vessels,” Dr. Munshi said. The beverages often include ginseng, guarana, theophylline and theobromine, all stimulants that can further strain the cardiovascular system.
Doctors have documented cases of cardiac arrhythmias, hemorrhages and strokes linked to heavy energy drink use. Some young adults combine them with cocaine or methamphetamine, a mix Munshi described as capable of causing “havoc.”
Munshi believes this case should push doctors to ask patients about energy drink use, especially younger individuals presenting with heart issues or stroke-like symptoms. He said the drinks have become more potent over time and may warrant stricter regulation and clearer public warnings.
“We propose increased regulation of energy drink sales and advertising, which are often targeted at younger ages,” he said.
