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.

What Is Raw Milk?

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.

Health Risks of Drinking Raw Milk

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.

Bird Flu Impact on Raw Milk Safety

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.

Legal Status of Unpasteurized Milk

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.

Why Pasteurization Is Important

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.

Myths About Raw Milk Products

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.

Should You Drink Raw Milk?

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.

Studies have found that fermented foods directly increase the diversity of the gut microbiome, improve blood sugar control, and lower systemic inflammation.

From yogurt to sauerkraut to kimchi and kefir, almost every culture on earth has fermented foods in its traditional cuisines. Fermentation originated naturally, long before human civilization, when wild yeasts and bacteria accidentally encountered sugars, spontaneously triggering chemical transformations.

Now, fermented foods are re-emerging as research is demonstrating their nutritional pros. They are preserved using an age-old process that not only boosts the food's shelf life and nutritional value, but can give your body a dose of healthy probiotics, which are live microorganisms crucial to healthy digestion, according to Dr. David S. Ludwig, a professor of nutrition at the Harvard School of Public Health.

Fermented foods are packed with probiotics that serve a plethora of purposes. Other benefits include:

1. Improves immune function
2. Protects against hostile bacteria
3. Improves digestion and absorption of food and nutrients.
4. Produce essential nutrients like vitamins K and B
5. Synthesize short-chain fatty acids
6. Increase bioavailability of iron, zinc, and other minerals

What Are Fermented Foods?

Fermented foods are defined as foods or beverages produced through controlled microbial growth and the conversion of food through enzymatic action. These foods are transformed by microbes intentionally, unlike spoiled foods that are altered unintentionally by microbes.

A lot of fermented foods are produced across the globe, including dairy, vegetables, grains, and legumes. Some of the popular ones that are consumed are sourdough bread, kimchi, curd, miso, etc.

When we eat fermented foods, the bacteria survive the digestion and make their way to the small and large intestines, where they secrete beneficial compounds, inhibit intestinal pathogens, and influence the composition of the gut microbiome.

Not all fermented foods contain live microorganisms. Major examples of this are chocolate and coffee.

1. Chocolate is made by fermenting cacao beans with natural yeasts and bacteria, which are killed off when the beans are heated and roasted.
2. Coffee is considered a fermented food because beans typically undergo a fermentation process. The microbes are destroyed when coffee beans are roasted.

The flavor profiles of both chocolate and coffee are influenced by fermentation, leading to the creation of that unique and rich flavour loved by everyone.

“A big part of the reason that chocolate or coffee tastes different is because of the way that it’s fermented in that region and the microbes that are present in that region,” said Chris Damman, a microbiome and nutrition expert and gastroenterologist at the digestive health center at the University of Washington Medical Center.

How To Eat Fermented Foods

Ideally, one or two servings of fermented food should be eaten daily, and new varieties should be tried to gain the full benefits of consuming different types of polyphenols, probiotics, and their by-products.

Fermented foods like kimchi, pickles, and sauerkraut can be relatively high in sodium, so avoid them when on low-sodium diets or with hypertension. Eating too many fermented foods can create problems for those who have a compromised immune system.

For those who are well, look for ways to incorporate fermented foods in your favorite dishes. Here's how:

• While having a burger or stir fry, add a topping of kimchi;
• While eating salad, top it up with sauerkraut sauce;
• If granola or cereal is being eaten, replace milk with kefir.
• Craving a snack? Have a bowl of plain Greek yogurt topped off with fruits instead of junk items.

How to Add Fermented Foods To Your Daily Meals

1. Add kimchi to everyday meals. Kimchi can be used as a side dish in sandwiches, wraps, burgers, rice bowls, or even on a toast for that spicy probiotic boost.
2. Swap regular yogurt with Greek yogurt. There is a wide variety of yogurt available that can be enjoyed by garnishing with fruits and granola.
3. Instead of sugary soft drinks, drink Kombucha- a fermented tea that offers a tangy flavor and refreshing feel.
4. Incorporate fermented soy products like Tempeh and Miso in stir fries, soups, salads, and gain bowls.

Bonus tip: Start with small portions and gradually increase the intake to allow your digestive system to adapt.

In a bid to strengthen food hygiene and safety standards, the Food Safety and Standards Authority of India (FSSAI) has directed Food Business Operators (FBOs) across the country to ensure that only food-grade, corrosion-resistant knives, blades, and cutting equipment are used in food handling and processing operations.

The directive, issued under Schedule 4 of the Food Safety and Standards (Licensing and Registration of Food Businesses) Regulations, 2011, also requires FBOs to maintain all cutting equipment in a sound and hygienic condition. In addition, the food regulator has asked State Food Safety Commissioners and Regional Directors to maintain strict vigilance and ensure compliance during inspections.

FSSAI Flags Use of Unsafe Cutting Equipment

"Schedule 4 of the aforesaid Regulations requires that equipment, utensils and food-contact surfaces used in food handling, preparation, processing, packaging and storage shall be made of food-grade, non-toxic, corrosion-resistant materials and shall be maintained in a hygienic condition so as to prevent contamination of food," FSSAI said in its advisory.

The regulations further require that such equipment and utensils be adequately cleaned and disinfected at appropriate intervals to prevent food contamination.

According to FSSAI, it has come to the regulator's notice that certain food businesses are using rusted, corroded, chipped, painted, damaged, or otherwise unsuitable knives, blades, and cutting equipment during food handling, preparation, processing, cutting, slicing, and packaging operations.

The food regulator noted that the use of rusted, corroded, chipped, painted, damaged, inadequately cleaned, or non-food-grade cutting tools can result in physical, chemical, and microbiological contamination of food.

What Did The FSSAI Advisory Recommend?

FSSAI has directed all Food Business Operators to ensure strict compliance with the following measures:

• Only food-grade, corrosion-resistant knives, blades, and cutting equipment should be used in food handling and processing operations.
• Knives, blades, and cutting equipment must be maintained in a sound and hygienic condition and be free from rust, corrosion, chipping, paint, cracks, breakage, or any other defect that may contaminate food.
• Rusted, corroded, chipped, damaged, or otherwise unsuitable cutting equipment must be immediately removed from use and replaced.
• Adequate cleaning, sanitization, and sterilization procedures, wherever applicable, must be followed at prescribed intervals.

FSSAI warned that any non-compliance observed will attract action under the Food Safety and Standards Act, 2006, and regulations made thereunder.

Unsafe Food A Major Public Health Concern

Unsafe food continues to pose a significant global health challenge. According to a recent World Health Organization (WHO) report, unsafe food causes approximately 866 million illnesses and 1.5 million deaths worldwide every year.

Children under five years of age bear a disproportionate burden, accounting for 29 per cent of the health impact linked to unsafe food. In 2021 alone, unsafe food was associated with an estimated 143,000 deaths among children in this age group.

The WHO also warned that exposure to chemical hazards in food, including methylmercury and lead, can damage the developing brain and result in lifelong neurological and developmental problems in children.

Eggs are a great source of protein. At the same time, they are one of the most common foods that cause allergies in children.

A new study conducted in Australia showed that introducing eggs to children before the age of one may reduce the risk of allergy by 17 per cent. The findings were published in the journal JAMA Pediatrics.

Jennifer Koplin, Associate Professor at the Child Health Research Centre at The University of Queensland, said: “Australia has one of the highest rates of food allergy in the world, with one in 10 infants allergic to one or more foods".

To curb the allergy rates, the Australian infant feeding guidelines, issued by the Australasian Society of Clinical Immunology and Allergy in 2016, revolutionized allergy prevention by advising parents to introduce well-cooked egg and smooth peanut butter soon after starting solid foods, generally around six months of age.

The research, led by a team from UQ and the Murdoch Children's Research Institute, examined 7,200 children in two Australian population-based studies to assess whether egg allergy rates had declined since the introduction of the guidelines. The risk of allergy decreased by 17 per cent among babies who started eating eggs early.

“Most parents followed the guidelines, and these results provide reassurance that this advice will help reduce the chance of their child developing an egg allergy,” Dr Koplin said.

Lesser Allergy In Infants With Eczema

According to Associate Professor Rachel Peters of the Murdoch Children's Research Institute, the reduction in egg allergy was more pronounced in babies with eczema, a known risk factor for food allergies. Among these children, egg allergy rates were reduced from 35 per cent to 22 per cent.

“The introduction of the 2016 guidelines was a major change from most advice given in the 1990s and early 2000s, which recommended parents delay giving eggs and other allergenic foods until 1–3 years of age if there was a strong family history of allergy,” Dr Peters said.

Allergenic Foods Before Age One

Other common allergy-causing foods, such as cow's milk, fish, sesame, wheat, and tree nuts, are also recommended to be included in a child's diet before one year of age. Dr Koplin, however, urged for more research into food allergies.

Common Symptoms of Egg Allergy

According to the Mayo Clinic, egg allergy symptoms usually start a few minutes to a few hours after eating eggs or foods containing eggs. While egg allergies can occur as early as infancy, most children outgrow their egg allergy by age 16.

Egg allergy symptoms can include:

• Skin swelling or itchy bumps called hives — the most common egg allergy reaction.
• Stuffy or runny nose and sneezing, also known as allergic rhinitis.
• Digestive symptoms such as cramps, upset stomach and vomiting.
• Asthma symptoms such as coughing, wheezing, chest tightness or shortness of breath.
