Raw milk has been linked to at least 10 illnesses in California, according to the California Department of Public Health. None of the illnesses has been identified as bird flu, the agency said.
“Since announcing multiple recalls of raw milk due to contamination with bird flu,state and local public health experts have received reports of illnesses from 10 individuals who reported drinking raw milk. Initial county and state public health laboratory testing has not identified any positive bird flu infections in these individuals to date,” a spokesperson said Thursday.
Health officials in Northern California are also investigating a possible case of bird flu in a child who became ill after drinking raw milk in November, Marin County Public Health said Tuesday.
The child went to a local emergency department with fever and vomiting after drinking raw milk and tested positive for influenza A, the county said.
Interest in raw milk has surged amid support from some high-profile fans, including Robert F. Kennedy Jr., President-elect Donald Trump’s choice to lead the US Department of Health and Human Services.
Although some fans claim there are nutritional benefits to drinking raw milk, health experts say any purported benefits do not outweigh the associated risks.
Raw milk and some types of raw cheese can be a source of many kinds of germs, and lab tests show that bird flu virus in raw milk can be infectious.
Raw milk and cream products from Fresno-based Raw Farm were recalled and distribution of the products was last month halted after samples tested positive for bird flu. Two possible cases of bird flu were reported in indoor cats who had consumed raw milk from Raw Farm, the Los Angeles County Department of Public health said Thursday.
In response to the increasing presence of the virus,the US Department of Agriculture has announced that it will begin testing raw milk stored in dairy silos across the country.
Raw milk has not undergone pasteurization, the process that removes disease-causing germs, yeasts, molds and other harmful microbes, according to the US Centers for Disease Control and Prevention.
Most milk in the US is pasteurized using High temperature Short Time Pasteurization, wich involves heating it to at least 161 degrees Fahrenheit for a minimum of 15 seconds, according to the International Dairy Foods Association.
The process was named after French chemist and microbiologist Louis Pasteur, who refined the process to use in alcoholic beverages such as beer and wine, later adapting the method to milk as a way to remove bovine tuberculosis in the US and Europe in the early 1900s. Roughly 65,000 people died of the disease after eating and drinking unpasteurized dairy products between 1912 to 1937 in England and wales alone.
Instead of pasteurization, raw milk producers monitor the health of the cow, according to Raw Farm CEO Mark McAfee.
Raw Farm uses smaXtec boluses, capsule sensors swallowed by the cows to measure their body temperature, water consumption, activity and general health. The capsules stay in the same position in the reticulum for the cow’s life, neither digested nor regurgitated.
The devices wirelessly transmit updates every 10 minutes. The data is then sorted by AI to provide information quickly, should a cow become sick, to ensure that the
Despite the hype, the FDA estimates that less than 1% of Americans drink raw milk.
Many fans claim to choose raw over pasteurized milk because they prefer the taste, according to Dr. William Hallman, a professor and psychologist in the Department of Human ecology at Rutgers University.
There are also a variety of psychological reasons,Hallman said. Some people believe it’s healthier than pasteurized milk, while others might want to support local agriculture or choose it because family, friends or neighbors enjoy it. It’s also more expensive, with some gallons of raw milk costing almost twice as much as regular milk at the grocery store.
“Psychologically, it reinforces the idea that it’s a premium product because otherwise they couldn’t charge so much for it,” he said. “There’s kind of this group effect that becomes normalized.”
According to the FDA, many of the claims about raw milk’s health benefits are not true. For example, it doesn’t cure or treat asthma, allergy or lactose intolerance, and it doesn’t have the good gut bacteria that could improve your microbiome.
“Pasteurization is meant to ensure the bad bacteria that can be harmful to people and make them ill are killed,” said Dr. Rabia de Latour, a gastroenterologist at NYU’s Grossman School of Medicine. “There’s been a lot of recent attention being paid to the concept of ‘processed’ foods being bad for your health. [Pasteurization] still provides some protein and aids in bone health by providing calcium and vitamin D to the drinker, but if you’re very concerned about your microbiome, I believe there are safer ways to enhance it.”
Some ways to improve your gut microbiome include consuming high-fiber and fermented foods,fruits,vegetables and extra virgin olive oil.
Raw milk has a neutral pH and ample nutritional and water content, making it an ideal environment for bacteria and other harmful pathogens to grow., research shows.
“Milk has around 87% moisture, and microbes love more moisture,” said Alex O’Brien, the food safety and quality coordinator at the Center for Dairy Research. “The more available water,the easier it is for them to grow.”
The CDC says that drinking or eating products made from raw milk opens the door to several harmful germs, including E. coli, listeria, salmonella and brucella.Another, Cryptosporidium, can lead to very dangerous diarrhea in people who have HIV or AIDS, de Latour says.
These foodborne illnesses can cause symptoms such as diarrhea, stomach cramping and vomiting. In rare cases, they may lead to serious conditions like Guillain-Barré or hemolytic uremic syndrome. The germs are more likely to cause health complications in children under 5, adults over 65, pregnant people and the immunocompromised.
Raw milk can be used to make raw cheese, and fans say it has a better, more complex flavor than pasteurized cheese. Dr. Don Schaffner, a food science professor at rutgers University, said the health risk from raw milk cheeses might potentially be considerably lower, depending on the type of cheese.
Hard aged raw milk cheeses like cheddar, Asiago, Parmesan or Swiss are much less risky than soft raw milk cheese like queso fresco, feta, Camembert or Brie, Schaffner said.
The CDC says that soft cheeses with a high moisture content are more likely to be contaminated with listeria bacteria.
The US Public Health Service created the Standard Milk Ordinance in 1924 to promote pasteurization practices and remove harmful bacteria that could cause typhoid and scarlet fevers and also tuberculosis.
The ordinance, now known as the Pasteurized Milk Ordinance, outlines the requirements for lab testing of milk and dairy products for quality and safety.
Experts estimate that, before the wider adoption of this approach, roughly 25% of all disease outbreaks in the US were milk-borne.
According to the FDA, for every 2 billion servings of pasteurized dairy products consumed in the US, about one person becomes ill.
Pasteurization “has been incredibly effective at reducing the incidents of milk-borne disease,” Schaffner said. “Any biological organism has optimal conditions that it prefers, and if those deviate, organisms are inactivated.Heat is a very straightforward technology that is easy to apply with precision, and its effect on pathogenic microorganisms is well known.”
Some health experts believe that people may continue to consume raw milk despite the health risks as they believe that the overall chance of illness is low.
“some people are extremely optimistic, and they believe that if there are risks, they are more likely to be much more likely to apply to other people,” Hallman said. “In this case, they may be focusing primarily on the health benefits and ignoring the risks because it’s more convenient to do that. They underplay the risks by overemphasizing the benefits to justify the choice they’ve made.”
Raw milk has become a notably hot topic as of Kennedy’s vocal support as well as endorsements from social media influencers and the “gwyneth Paltrows of the world,” Hallman said. Paltrow has said she drinks raw cream in her coffee.
“The evidence for these health benefits is certainly not definitive, whereas the risks certainly are definitive,” he said. “Having worked on a farm and been around cattle, I can pretty much assure you that everything is not sterile around those animals. There’s this romanticized view of this, which is not entirely realistic.”
The credibility and position of those endorsing the product, like Kennedy, who said in a social media post in October that raw milk was among a long list of items that faced “aggressive suppression,” also seems to play a role in raw milk’s recent attention.
“There’s nothing more American than the freedom to choose what kind of food you eat,” he wrote. “Raw milk isn’t for everyone, but that doesn’t meen it shouldn’t be available. Just as we shouldn’t force people to consume something they don’t want, the government should allow people the right to choose what is best for their personal nutrition.”
“Kind of perversely, some people drink raw milk because they don’t want the government telling them what they should do,” he said. “They support drinking raw milk because they want to maintain their ability, their freedom of choice.”
This bird flu virus has caused “widespread” illness in a multistate outbreak among US poultry and cows, according to the CDC.
When cows are infected with this strain of bird flu, Schaffner said, the concentration of the virus shed in milk can be quite high. “Eventually, cows become sick and either stop producing milk or produce poor-quality milk,” he said.
The CDC has reported 58 human cases of bird flu this year, 32 of them in California, where raw milk is legal to drink and sell.Most of the cases are linked to farm workers who have been in contact with sick animals.
Bird flu symptoms in humans include flu-like symptoms like eye redness, sore throat, runny nose, cough, diarrhea, vomiting, body aches, fatigue, trouble swallowing or fever.Health experts encourage anyone who has consumed raw milk and notices symptoms to alert their health-care providers or local health departments.
“We’ve seen the flu move from birds to cow,” de Latour said. “If you were to drink raw milk of a sick animal shedding this virus, theoretically, yes, maybe you could possibly contract bird flu, but we haven’t seen that happen yet.… The ultimate big fear here is human-to-human transmission, which we have not yet seen.”
How do consumer perceptions of raw milk influence their purchasing decisions despite safety concerns?
Might prioritize perceived taste preferences adn perceived health benefits over safety. The psychological and social factors behind this choice can be quite strong, leading consumers to partake in raw milk despite the risk of foodborne illness.
Moreover, the novelty of raw milk and it’s positioning as a “premium” product could create a sense of exclusivity and appeal among certain consumers who associate it with higher quality, local production, and traditional farming methods. This aligns with the modern consumer trend leaning towards organic and locally-sourced foods, where the narrative of “real” or “natural” resonates more with buyers.
Researchers and health professionals continue to promote that while the taste may differ, the safety and health implications of consuming pasteurized milk far outweigh the benefits of raw milk. Continuous public health campaigns aim to educate consumers about the risks associated with raw dairy products and encourage them to consider safer alternatives for their dietary needs.
the debate surrounding raw versus pasteurized milk underscores broader themes in public health, consumer behavior, and food safety, emphasizing the need for awareness regarding food choices and their consequences.
