Bird flu, bird flu, bird flu. I'm sure you've seen scary headlines like these:

💥 "Deadly flu virus is not just for the birds anymore"
💥 "Bird flu has spread to dairy cows. Is our milk safe?"
💥 "Could Avian Influenza Be The Next Covid-19?"

I mean, how sensational. At this point, you've likely had (at least) a small moment of fear. You maybe have even done an internet search on "bird flu symptoms" (or something like that).

I mean, the government and the media do such a good job of seeding fear about disease. Any fear or anxiety you have about this is not your fault. Gee, just imagine how you'd feel and what the headlines would look like if, instead, the focus switched to spreading hope about natural health! That would be the day.

What's really going on? What do we have evidence of? What questions remain unanswered? Here's a breakdown of it all from my perspective.

Heads up -- it's a loooong post. It needs to be. Instead of fragments of scary information like most media sites put out there, I figure I'd take the time to delve deep and answer the questions that I have (and you might have, too).

*As a disclaimer, I'm not a doctor or a scientist. I'm a passionate real food consumer that loves research and learning new things. Sources are listed at the very bottom.

The truth is that there is zero evidence of viral transmission from milk to humans (even raw milk).

Yes, strains of bird flu were found in US milk (and fragments of these strains were found in pasteurized milk). However, the CDC and USDA reported that the strains lack the genetic markers for viruses adapted to infect humans. You heard that right. Anything that would potentially be in the milk can't infect humans.

The two people infected in this "outbreak" have been farm workers who've had direct contact with infected animals (and, by the way, with one of those cases it's unknown whether the animals were cows or dead birds).

For farm workers, the "WHO assesses the public health risk to the general population posed by this virus to be low and for occupationally exposed persons the risk of infection is considered low-to-moderate." So low risk for everyone, and low-moderate risk for farm works.

Furthermore, the two people infected have NOT transmitted it to another human. Sure, the virus could mutate to spread from human to human, but that's not the current reality.

Raw milk has antiviral properties that can prevent disease.

Science shows that raw milk can inactivate viruses and prevent foodborne illness. Multiple researchers have shown that this is a synergistic effect, meaning that there's not one specific thing in the milk that provides this protection. Rather, it's a combination of many things working together in our complex gut ecosystems that include innate and adaptive immune systems

Beyond the studies, this just makes sense in our gut. Let's take this example. Say a breastfeeding mom gets sick. She should NOT stop breastfeeding. Rather, she should 100% continue because she passes immunity along to protect the baby.

It's my opinion that it's better to improve your immune system than try to avoid a specific handful of the billions of bacteria and viruses around us (terrain theory, not germ theory). With potentially harmful pathogens, it's not an "if" you come in contact, it's a "when" you come in contact. Strengthening your body and immune system is your best defense (rather than avoidance).

There's zero evidence showing spread through eating meat or eggs.

I don't think I need to write more here. The above sentence says it all.

Unanswerable Bird Flu Questions

The hard part about writing about bird flu right now is that I have so many questions that I simply cannot find answers to. How can I have an educated stance when I'm confused, when I don't feel like I have all the info? Here are some questions that I'd love to have answered to help formulate a truly educated opinion.

--> How widespread is bird flu in cows? How many farms have been affected?

Some charts show number of positive tests in animals, some show positive milk tests, and some show it combined. Some show the number of states affected, and some show the number of farms. You need to be diligent when looking at the numbers.

From what I found, as of May 2, it looks like there are 36 herds that have had at least one cow with a positive bird flu test. Since there's about 25,000 dairy herds in the US, about 0.1% of farms that have been affected. If we round, that's 0%.

It's my understanding that these are only farms with a reason to test. How many farms have cows with bird flu and don't know it? Furthermore, how sensitive are the tests? Are we counting tests for the full virus, fragments of the virus, or a specific amount of the virus?

So many unknowns and opportunities to skew data to make a point.

--> Are there any farming practices that make bird flu transmission to cows more or less likely?

When there's a food safety risk, headlines nearly always say things like "Dump milk from This Specific Farm" or "Throw away your lettuce from This Specific Company." They call out the specific farm or company producing the food.

But, with the bird flu thing, it's very vague. The articles say "a farm in Texas" or "a farm in Colorado."

Because they're not naming names, I can only assume that the farms affected are part of big ag. They likely sell their milk to mega companies, which are lobbying to protect their brand name (and sales). And that means that, most likely, the infected cows live inside, are fed corn and soy, are given drugs, and all that industrial ag stuff.

And, if that's the case, then it means that cows on small natural farms like ours would be much less likely to contract bird flu. The cows are outside as much as possible (at this time of year, it's all day and night), they eat a natural diet of grass, and are drug-free. They're in natural health. The outside thing might be the biggest variable, because just like with COVID (and basically any virus), outdoor viral spread is rare.

But, of course, I have no way to prove this one way or another. Again, they're not naming farms! And, even if they did, big ag will protect its name. Those industrial farming practices are just fine, right? This makes it impossible to draw any conclusions about why transmission to cows happened in the first place.

--> How serious is bird flu in humans?

This should be a simple one, right? Nope. The info out there is quite confusing.

According to the CDC, "The signs and symptoms of bird flu virus infections in humans range from no symptoms or mild illness such as eye redness or mild flu-like upper respiratory symptoms to severe illness such as pneumonia requiring hospitalization." OK, that sounds like a normal flu virus. Symptoms range from mild to severe, and the most vulnerable are probably those who are immunocompromised (sick, elderly, etc).

But then, according to the WHO, the death rate is 56% (other sources cite the fatality rate from 40-60%). Seriously!?!? If that were true for all people, it would be truly terrifying.

Most likely, there should be some disclaimers about the fatality stats. I'd like to know these things. Was the percent based on hospitalized people only? If some people show no symptoms, were they be included in the total count of those infected (of course not)? Where did these deaths happen? How long were people infected before getting treatment? What was the quality of care and resources in those hospitals?

But, let's stop and think. How can anyone put a scary stat about death out there without some serious disclaimers about the data? It's obvious that that stat is for people who are already very sick and hospitalized.

--> How does bird flu get into milk anyway?

Bird flu is a respiratory disease, NOT a blood disease. Why is this important? Because milk is made from blood. If the bird flu virus isn't in blood, then there's no way for it to get into the milk (at last the milk when it's inside a body).

So, how does it get into the milk? Articles online haven't really explained this. They've only cited that fragments of bird flu have been found in pasteurized milk. In the same articles, they tout how amazing our testing capabilities are and how we can detect even the smallest fragments. So how much of the virus is in the milk is unknown, too.

Again, how does the virus get into milk? The only explanation is that it must be from an outside source. Perhaps droplets from an infected cow's saliva, respiratory droplets, urine, or feces. Another theory is that mastitis happens as an inflammatory response, and the infection is spreading to the teats. But again, this is yet to be proven.

In my opinion, it's most likely from respiratory droplets in the air in poorly ventilated milking spaces. But again, I have no way to prove that.

--> Why the hype?

Given the data, bird flu in humans doesn't seem like a big threat. This is especially true when compared to the wars, malnutrition, lack of clean water, and all the other huge issues around the world.

So, why? I mean, it's definitely click bait that gets ratings up. Maybe it's just something to talk about. Maybe it's a distraction from other news. Maybe it's a ploy to promote pasteurized dairy. Or maybe it's to promote a new bird flu vaccine. We may never know!

What is Miller's Bio Farm doing to prevent bird flu?

Well, we're going to continue doing what we normally do. Our cows will live a naturally happy, healthy life. They're outdoors at pasture as much as the weather allows. They eat a natural diet of 100% grass. We have meticulous cleaning and milk safety standards to minimize any potential pathogens getting in the milk. And, as usual, we carefully watch the health of our cows (they rarely fall ill).

We will not be testing for bird flu... unless we're required to. We don't feel it's necessary. Given the current info, we don't view bird flu as a risk. If we see evidence showing otherwise, of course we would take action then.

What do you think about bird flu? Are you nervous, or is it just hype?

Why it's nearly impossible to avoid maltodextrin in fermented dairy.

If you dove deep on our website and clicked on a product to get all the nitty gritty details, you may have noticed the "Honest Disclosure" section. That's right. We believe you deserve to know everything about your food - the big, the small, the good... and even the bad. On most of our fermented dairy (cheese, yogurt, kefir, cottage cheese, etc), you may have noticed a message saying that the freeze dried culture contains a trace amount of maltodextrin 😱 And you may have thought, "What!? I thought they made the most natural food around!" You're right. We do aim to provide you with the most natural foods around, from the farming practices to how they're made in small batches. We want you to have max nutrition and the least toxins possible. And honestly, we're not thrilled to have even a trace of a trace amount of maltodextrin in our fermented dairy. But, sadly, there's simply no way to do that nowadays, especially considering the demand for specific flavors, consistent textures, and a reliable food source. Like seriously, when it comes to maltodextrin, the only difference between Miller's dairy and any other dairy (whether from a supermarket or a farm) is that we did the research and are actually telling you about it. We don't need to. It's not required. But... you deserve to know. So, what's going on with maltodextrin? There's so much more to this story! Keep reading to be a smart natural food shopper and get all the info. What is maltodextrin anyway? Maltodextrin is a sugar, a very simple sugar. Scientifically speaking, it's "short chains of glucose units", a type of "oligosaccharide". Maltodextrin is 100% a lab-produced ingredient. They take a starch (a complex carbohydrate that your body would digest into sugar) and break it down using enzymes or acids. The result is a simple sugar. Labs are basically cutting that long, complex chain that makes up a starch into shorter, simpler segments. Maltodextrin can be made from a bunch of different kinds of starches - corn, wheat, rice, potato, cassava, etc. In the US, it's most commonly made with corn. Depending on what the maltodextrin is derived from and how it's made, it can have different properties and uses. It's most commonly dried into a white powder but can also be found in syrup form. Maltodextrin is used in food as a stabilizer, thickener, anti-caking agent, and bulking agent. I mean, it's in soooo many processed foods. It can also be used in livestock feed or healthcare products as an easily digestible sugar source. Maltodextrin does NOT need to be certified organic in healthcare products (supplements, etc). But, it does need to be certified organic in livestock feed and foods that are certified organic. What would make maltodextrin certified organic? It's how it's broken down. According to OMRI (the Organic Materials Review Institute that approves things for organic use), maltodextrin made with acid is NOT certified organic. Maltodextrin made with enzymes is certified organic. Apparently they believe the enzymatic way is considered "natural". Why would people want to avoid maltodextrin? The FDA classes maltodextrin as a GRAS (generally recognized as safe) food additive. That being said, there are known risks to consuming maltodextrin, especially in larger amounts (which you can absolutely get from processed foods). Here are some potential negative health consequences of overconsumption of maltodextrin: High cholesterolWeight gainType 2 diabetesBlood sugar spikes (particularly in people with diabetes or insulin resistance)Imbalance of gut bacteriaAllergies or intolerances (to corn or wheat) with a range of side effectsExposure to GMOs (when derived from GMO corn) Keep in mind that any of the above side effects typically arise from consuming maltodextrin in large amounts. A trace amount usually won't negatively impact your health unless you have a severe allergy to it (or what it's derived from or made with). What is a freeze dried culture? Freeze dried cultures are surprisingly old. They originated in the late 1800s as a way to preserve the best cheese and dairy cultures and share them over distances. But the technology didn't become really good and reliable until the mid 1900s. That's when they started becoming popular. The process to make them is fairly simple. Like, you can totally do it at home (maybe you've done it with sourdough starter...?). But... for best accuracy and use, freeze dried cultures are best for commercial use and are made in labs nowadays. Here's how it's done: 1- Strains of microorganisms are isolated and grown. The first cultures were made by letting raw milk grow wild. Then, each strain of bacteria, yeast, etc was isolated. This can be done with a particular solution or by putting fermented raw milk on a medium that only supports a specific kind of microorganisms. It's kinda like terrain theory here. Nowadays, labs generally aren't isolating their own cultures much. Instead, they're maintaining cultures separated a longtime ago. It's kind of like culture makers are literal "micro farmers" growing microorganisms. But, instead of planting in the soil, they let each culture grow in pasteurized milk or a specific growing medium (like some kind of something scientific in a petri dish). And, it's 100% in a controlled lab environment. There might be one type of lactic acid bacteria multiplying in one tray and a certain kind of yeast in another. 2- Strains are freeze dried. Each isolated strain is usually freeze dried individually. A freeze dryer is a freezer... but with a vacuum that removes the air. Cool! You could freeze dry anything in a regular freezer, but it would take much much longer. The vacuum element of a freeze dryer makes it so any water turns right into vapor (or dries out) instead of turning to ice. 3- Strains are mixed together to make a specific culture "recipe". It's like a recipe. It might be 3 parts Bifidobacterium lactis, 2 parts Lactobacillus acidophilus, and 1 part Lactobacillus delbrueckii subsp. bulgaricus. The specific strains mixed together are what give each fermented dairy product it's unique texture and flavor. Other ingredients might be added for specific reasons. Sugars (like maltodextrin or sucrose) help keep the culture in good condition and aid it in coming back to life when used. Enzymes (like lipase) might be added to give better flavor. Or colors (like annatto or synthetic dyes) might be added for a desired yellow or orange color. Why is maltodextrin added to freeze dried cultures? In cheese cultures, maltodextrin has a double purpose. It's an anti-caking agent, keeping the culture as a powder... not an unusable clump. It's also a simple sugar that gives the culture something super easy to digest as it comes back to life. Without maltodextrin, freeze dried culture issues would be quite common. They would stop working or have spotty success. How much maltodextrin ends up in the final product? Maltodextrin is used in small amounts in a freeze dried culture. Maybe with some cultures it's more, but with ours, it's less than 1%. Just a little bit is needed. I'm not sure about this with other dairy makers. But, I can tell you how much culture is in Miller's dairy items. For our cheese, about 1/2 tsp of culture is used in 1lb of cheese. For our fresh fermented dairy like yogurt or kefir, about 1 teaspoon of culture is used per quart of milk. There are 96 teaspoons in a pound of cheese and 192 teaspoons in a quart of milk. So, culture alone is 0.5% or less of the final product. And, if maltodextrin is less than 1% of the culture, we're talking less than 0.005% maltodextrin. On top of that, once the culture is added, it eats up that maltodextrin immediately. I mean, that's the whole point. It's a quick simple food to get those freeze dried cultures active again. Let's say that only half of the maltodextrin is eaten by the cultures. Then there would be less than 0.0025% maltodextrin in the final product. Can we round that to zero...? You see where I'm going. This is why we are ok with the level of maltodextrin in our cheese cultures. We absolutely wouldn't choose it as an ingredient. But, as it stands now, the only cultures available have maltodextrin. If you know of one that doesn't, please let me know!!! If I'm NOT shopping at Miller's, how can I find out if maltodextrin is in my food? Maltodextrin is only required on an ingredient list if it's more than 1% of the final product. If it's less than 1%, then it's not required on a food label, because it's considered a "trace amount". 1% and 0.0025% are very different trace amount levels but are treated the same when it comes to labeling. In fact, when shopping for cheese cultures, maltodextrin typically isn't listed as an ingredient. The only way to find out is to look at the Safety Data Sheet or to call the manufacturer and cross your fingers that they'll talk to you. I think that most farms or dairy makers that get this question would simply say, "Nope, there's no maltodextrin." But, that's not the way we roll at Miller's. A few years ago, someone who had a severe allergy reached out about this. It led me down a rabbit hole, talking to the scientists behind our cultures. And now, I'm sharing what I learned with you. Is there a way to make fermented dairy without maltodextrin, like a wild (not freeze dried) culture? Sure, wild cultured dairy is 100% a thing. It's like the sourdough bread of the dairy world. But... as the name implies, the final product can be a bit "wild". This is how we make our bursting kefirs. They're made with real kefir grains (a wild culture) that's been passed down in our community for generations. As this name implies, it can be explosive and super bubbly. It can be quite strong in flavor (not everyone's cup of tea). And it varies a lot from week to week. If we made cheese with culture we saved, it wouldn't turn out the same every time. We wouldn't be able to have a reliable cheddar and gouda and mozzarella... we'd just have one cheese that turns out a little different every time. If we made yogurt with culture we saved, it's a little more reliable. But, it still wouldn't give you the expected texture and flavor of the yogurt you're expecting. And, there would likely be weeks it simply didn't turn out right. Which Miller's dairy products contain trace amounts of maltodextrin and which don't?
