One of the top customer questions we get is, “Do you vaccinate your animals?” I wish the answer was simple. I wish it was a direct yes or no, but it’s more complicated than that.

**We have never routinely vaccinated our animals.**

When animals eat a natural diet and live outdoors with plenty of fresh air and sunshine, there is little worry about disease. They are naturally healthy.

But, there have been a couple circumstances that led to our animals getting a vaccine.

This is, of course, not ideal. But, you deserve to know everything about your food so you can make educated decisions about what your family consumes.

1- We bought an animal from another farm. And, the farmer did not know his animals were vaccinated.

Vets will often vaccinate without asking permission. If the farmer doesn’t watch closely and keep his records organized, this can go under the radar. This is especially true when you buy in animals.

We actually had a problem with this in 2019. Farmer Aaron had bought in cows from a local farm years earlier, and one cow was still shedding RB51, the vaccine strain of brucellosis. The issue was completely resolved quickly, and you can learn more about the RB51 situation here.

2- There was a disease in a herd or flock, and we believed that immunization was the only solution to prevent death and suffering.

Listen, we care deeply about our animals and try to raise them as naturally as possible. But, in the rare case that a deadly disease infects our animals, and there is no natural remedy to tackle it, then we will turn to conventional medicine. We want to ensure the best life for our animals.

This happened about a little over a year ago. Farmer Aaron’s brother David started a second dairy farm for us. And, as with any new operation, there were some challenges. One of those challenges was bovine pneumonia. He quickly decided to vaccinate his cows to prevent death and suffering. He didn’t think there was another option.

FYI - The vaccine used on these cows was the Inforce3® Respiratory Vaccine. It’s an “old fashioned” vaccine (NOT mRNA) that’s made with a modified live virus (AKA a GMO virus). It’s an intranasal vaccine; that means it’s NOT injected but put in the cow’s nose. Keep in mind that there is a difference between injection and ingestion (more on that below).

Side note: None of the cows on our main farm are vaccinated. This is where all of our bottled milk comes from.

This is the honest truth. Since this blog post was originally published in November 2022, we got such insightful and passionate feedback from our customers. It really made Farmer Aaron think.

This is our hard stance:

NO MORE VACCINES, and definitely NO mRNA vaccines. We will be 100% vaccine-free by 2025.

A few notes on this:

If bovine pneumonia ever becomes an issue again, we’ll use a radically old fashioned, natural remedy - vinegar and red pepper. It seems to work just as well as the vaccine. The cows don’t “like” it, but I suppose it’s better than pneumonia. They put a mixture of vinegar and red pepper in the infected cow’s mouth. It seems to clear symptoms within a day or two.
Farmer David will slowly sell any cows that received a vaccine, and we will be 100% vaccine free by 2025. We don’t want any animals that have had vaccines. The process has already started, and we should be vaccine free by 2025.
And, along these same lines, we say NO to mRNA vaccines. This stands for ALL the farms we work with. We are a community of natural farms that says no to GMOs (and much more), why would we be ok GMO-ing our animals? mRNA vaccines are a hard no for us.

Let’s put this into perspective. There is a stark difference between what I explained above and the routine immunization practices used on conventional farms, even organic conventional farms.

There’s no pretty chart with a livestock immunization schedule, like the one from the CDC for human children. But, I did a little digging, and here are the vaccines that vets may recommend:

Cattle

Rota-Coronavirus
Bovine Rhinotracheitis (IBR)
Parainfluenza Virus 3 (PI3)
Bovine Viral Diarrhea (BVD)
Bovine Respiratory Syncytial Virus (BRSV)
7 Way Blackleg - 1 dose
Pasturella
Pinkeye
Brucellosis (Bangs)
5 Way Lepto
Camplyobacter

Pigs

Atrophic Rhinitis
Erysipelas
Mycoplasma Pneumonia
Actinobacillus Pleuropneumoniae

Broiler Chickens

Marek’s disease
Newcastle disease
Infectious bronchitis
Infectious Bursal Disease

Laying Hens

Marek’s disease
Newcastle disease
Infectious bronchitis
Infectious Bursal Disease
Encephalomyelitis
Fowlpox
Laryngotracheitis
Mycoplasma gallisepticum

Turkeys

Newcastle disease
Hemorrhagic enteritis
Fowl cholera
Erysipelas

As with childhood vaccines, most livestock immunizations call for many doses within the first year, and then an annual dose each year thereafter.

So, for example, beef cattle could get a specific vaccine 4 times in their first year, and then 1 annual shot, for a total of 5 injections for one disease before harvest. According to my calculations, an average conventional beef cow would get about 30 shots before you eat it.

Really what’s going on here is two different thought processes, two different ways of being and farming.

On the one hand, we have naturally raised animals who rarely get sick. This is because they eat a natural diet and have plenty of exercise and space and fresh air. Animals raised this way do not need routine vaccinations. This is how Miller's does it.

On the other hand, there are conventionally raised animals who are likely to get sick without intervention. This is because they eat an unnatural diet, primarily corn and soy. They live in crowded living spaces, often indoors. They’re not able to exercise or breathe really fresh air. Animals raised this way would not produce food or survive without routine vaccinations and antibiotics.

There’s so much to consider here. These two different ways of farming exist for a reason. The cost of food, varying income levels, profit for big businesses, farmers' contracts with distributors, the cost for farmers to build new facilities or buy land, damage that’s already been done to the soil, etc.

It’s also important to note that there is a difference between injection and ingestion.

Some vaccines for livestock are oral or nasal and some are by injection. First off, with an oral vaccine, the cow has a more natural immune response. And second, no matter what, if you eat (or ingest) food produced from a vaccinated animal, whatever would pass to you is through digestion.

Your body has an amazing and complex system for removing toxins that you drink or eat or breathe in. Most of this work is done by your kidneys, which filter toxins so you can excrete them in urine.

On the other hand, when you inject something into your body, like many vaccines, it goes straight into your bloodstream. Your body is not designed to remove toxins in the bloodstream as well as those in your digestive system.

No matter which way toxins enter, your body can only detox so much. It can only handle a certain amount of toxins. It’s like filling a cup with water. The cup can only hold a certain amount of water. Once the water reaches the brim, it cannot handle any more.

Miller’s Bio Farm aims to provide you with clean foods, and this means limiting toxins as much as possible. But, we are not perfect. That’s why we add honest disclosures to our products.

What do you think about vaccinations in animals? Are you comfortable consuming vaccinated animals? What about if they are minimally vaccinated?

Raw Dairy

Raw milk or fermented dairy and lactose intolerance. Why might it help?

I was misinformed. At some point, I read that raw milk contains lactase. As it turns out, this is not true! It is true that raw milk contains many live enzymes that are inactivated during pasteurization. But, what about lactase? I’ve heard many anecdotal stories from people who are lactose intolerant... but can handle raw milk or fermented dairy. If raw milk, yogurt, kefir, or cheese doesn’t contain lactase, then why is that?

Our bone broth tested A+++ for heavy metals 🥳 NATURAL AND CLEAN

*Originally published on 3/14/25. Updated on 4/15/25. Over the past few months a bunch of people asked us if we tested our bone broth for toxic heavy metals. When we get the same question a lot, we of course look into it. My first question was --- Is there an issue with toxic metals in bone broth? As it turns out, yes, there "can" be an issue! Heavy metals are naturally present in our environment. We need the "good" heavy metals to thrive: iron, zinc, magnesium, copper, etc. But, we can 100% do without the toxic heavy metals: arsenic, cadmium, lead, mercury, etc. Too many toxic heavy metals can lead to a host of pretty awful issues: nervous system damage, cardiovascular issues, cancer, endocrine disruption, kidney damage, and so on. Our body is designed to excrete heavy metals through urine (and a little bit through sweat, hair, and breastmilk too)... but only so much. There's a limit. If you're overloaded, your body will store those heavy metals in your bones, blood, tissues, and organs. Similarly, if an animal is exposed to heavy metals via food, water, air, dust, or soil, those heavy metals accumulate in the bones. Maybe the farm's soil or air is contaminated from a nearby factory. Maybe the pipes for the water has lead solder connecting them. Maybe the feed a farm is buying was grown on contaminated soil or processed on contaminated equipment. And, of course, a main purpose of bone broth is drawing out as much as possible from the bones. If there are heavy metals in bones, they will make their way into the broth. This is especially true when you use apple cider vinegar to draw everything out and make it thick and gelatinous (like our broth). And that led me to my second question --- Should I be concerned about every bone broth? Where is the fear coming from? Well... it seems it might be a little political. There was a study done in the UK in 2013 that scared a lot of people. It's titled "The Risk of Lead Contamination in Bone Broth Diets". This study found high levels of lead in organic chicken bone broth, which is quite concerning. And, in fact, this one study is still cited in articles written today! Let's dig a little deeper. Let's go farther than the short abstract. Here are the broths tested in the study and their test results for lead: (9.5 parts per billion): Broth made from tap water plus skin and cartilage(7.01 parts per billion): Broth made from tap water plus bones(2.3 parts per billion): Broth made from tap water plus meat(0.89 parts per billion): Tap water alone cooked for the same amount of time as a control. But, they only used organic chicken from one farm. And, there's zero information about that farm, their practices, the feed, and the broth recipe. Did they use vinegar or wine in the broth? Was the chicken's water contaminated with lead? What was the quality of the feed and the soil? Were the chickens raised indoors or outdoors? So many unanswered questions! All we get is that it was one "organic chicken" that created a lead issue with broth. Another curious thing is that the broth with skin and cartilage contained more lead than the broth made with just bones. Bones are where lead is stored, so why wouldn't the broth made with bones only contain more lead? It's an odd result. Moreover, the abstract of the study specifically called out "bone broth diets" like GAPS and paleo. They even go so far as to write, "In view of the dangers of lead consumption to the human body, we recommend that doctors and nutritionists take the risk of lead contamination into consideration when advising patients about bone broth diets." That's quite curious. Why are they worried about these diets? Are the researchers anti healing through food? Who funded the research? Is it political? My opinion? This study is not comprehensive. It does not speak to all bone broths. But it does cover a potential issue if the water or animals are overloaded with heavy metals. And, as we know, our poor planet is becoming more and more contaminated with toxins like these toxic heavy metals 😢 What I glean from this study is that we need more research. We need to stay vigilant and test from time to time. We don't need fear to spread and people to stop drinking broth from this one study. Regardless of whether the fear was fabricated or legit, we tested our bone broth anyway. After all, it's always nice to validate that your food choices are as clean as you think. For Miller's, here were my concerns before testing: What if there's mercury in the fishmeal in our chicken feed?What if the soil that our animals live on is contaminated?What is the well water that the broth is made with is contaminated?What if the Celtic sea salt has lots of heavy metals? We actually tested twice. As it turns out, the first test results from March had too high a LOQ (limit of quantification). So, we sent new products in April for testing at a lower LOQ. The results are in! Our bone broth tested A+++ for arsenic, cadmium, lead, and mercury. You can find the actual Eurofins test results right here! For easy reference, here's a chart summarizing the results: You'll notice that, for every sample, the results are "<1.0 μg/kg" and "<4.0 μg/kg". The "<" indicates the limit of quantification (LOQ), the lowest concentration that can be accurately tested using the test procedure in that sample type. So if a "<" result appears, it means that none of that metal was found in the sample above the specific reporting LOQ. Whether or not they were present below this LOQ is information that's not provided by the test. It's also important to note that a μg/kg is a part per billion (ppb). So, for 1 μg/kg, in every billion grams of that food, there would be one gram (or 0.0000001%) of that particular heavy metal. This small numbers matter when it comes to toxic heavy metals, since it doesn't take all that much for your body to become inundated and start experiencing issues or damage. These results are excellent. It means the broth definitely isn't overloaded with toxic heavy metals and are within safe levels. Our amazing customers mentioned Mike Adams to me numerous times after we released the first set of broth results. Mike Adams is an outspoken consumer health advocate, investigative journalist, activist, and science lab director. It turns out Eurofins, the lab we used, is a lab that he recommends. Moreover, our results land us in his highest rating when it comes to heavy metals! I think we're doing pretty great when it comes to providing clean, natural food. But, the results did make me pause. You might be thinking what I first thought -- "But wait, you got a positive reading for arsenic. Isn't that bad?" Let's dive in -- Where would arsenic in food come from? First off, it's important to note that there are organic forms of arsenic as well as inorganic forms. Our body can handle the organic kind pretty well. But, the inorganic kind is carcinogenic. Our test results show the level of all arsenic, and it doesn't divide inorganic and organic. Second, it was a mystery to me how arsenic had a reading in the ground beef but not the beef bone broth. Thankfully, that has a pretty easy explanation. Whereas lead mainly accumulates in the bones, arsenic accumulates more in the organs and muscles. And, of course, meat is muscle. It was also quite perplexing how arsenic showed in our beef as well as our chicken. You see, our beef and chicken are grown on two separate farms (hours apart) and are processed at two separate processors (also hours apart). They're fed two completely separate diets, too! My only explanation is farmland in general or maybe even our environment in general. Organic arsenic has always been naturally present in the soil and water. It's just there in small amounts. But, levels nowadays are likely higher due to overuse of products laden with inorganic arsenic over time. Starting in the 1940s, conventional farmers would include drugs filled with inorganic arsenic in the feed for pigs and chickens and turkeys to encourage fast growth and prevent disease. Ugh. This actually led to concerns about arsenic poisoning, and that that practice was banned recently, in 2016. It makes me think that all the agri-waste has contaminated our farmland a bit, perhaps in both the soil and water. And then of course there are synthetic pesticides and herbicides and fertilizers that may contain inorganic arsenic. And their use on conventional farms might runoff everywhere else. Now, let's compare our results to food in general. Ours are extremely low. The data below is based on a few scientific studies: Arsenic: Rice contains anywhere from 90-450 ppb (that includes that rice cereal for babies, too). Meat and poultry in general typically contain 100-200 ppb.Cadmium: Spinach contains 1117-222 ppb. Rice contains 6-19 ppb. Meat and poultry in general contain about 10 ppb.Lead: Meat and poultry in general contain about 25 ppb.Mercury: The larger the fish, the more time it has to accumulate mercury. Swordfish and king mackerel can have about 1,000 ppb. Meat and poultry in general contain about 10-50 ppb. Wow! Putting that into perspective, it looks like our broth and meat are quite clean and extremely low in toxic heavy metals! Are you satisfied with our heavy metal results? Do you think we should take further action? Should we test other products? Do you worry about toxic metals (or other junk) in your food? Where have your fears stemmed from? I'd love to hear from you.
