Last week, we had an e. Coli scare. Gasp! Please don’t freak out. It was a false positive, and we kinda knew it would be like that. But, that didn’t mean that our farm world wasn’t turned upside down because of it. Here’s what happened.

Because we’re certified for raw milk for humans in Pennsylvania, the State does periodic third-party testing for SPC (standard plate count), SCC (somatic cell count), TCC (total coliform count), Salmonella, E.coli, Listeria, and Campylobacter. 

The State took a sample of our main farm’s bulk milk tank on Wednesday 8/2. Then, on Monday 8/7, we found out that it came back positive for e. Coli (FYI everything else was negative). 

How did we find out? Well, an Inspector came to the farm and red taped all dairy products that could have been contaminated: all of our raw milk and all of our raw dairy products. They even tried to red tape our pasteurized dairy products, despite the fact that pasteurization kills e. Coli! Ugh. Thankfully, Aaron talked them out of that last one.

And I mean “red tape” in the literal sense. The Inspector literally put red tape over the products on the shelves. And, if we were to sell them, it would be illegal. It’s like caution tape, but red. And even though it’s obviously and easily removable, it feels pretty official and permanent and scary. 

What were we to do? Do we sing from the hilltops, spread fear about this freak positive test, and let customers know what we’re actively doing about it? Or, do we keep our heads on straight, act fast, and figure out a way to get our customers definitely safe dairy? We chose the latter.

First off, we know how vilified raw milk and a handful of potentially harmful pathogens are now (out of the trillion species of microorganisms on Earth). We live in a modern, sanitary, safety conscious culture reliant on avoidance and fear. We didn’t want to perpetuate that fear… at least not prematurely. In my opinion, I think we should focus more on building immunity and resilience within our bodies.

Second, being in this business for a while, we know that the State’s tests are notorious for being ultra sensitive (dare I say faulty) and that, in most cases, the first positive is actually a false positive (I think y’all can commiserate from our collective pandemic experience).

The State doesn’t consider one test alone a definite sign of contamination. You need two positive tests to confirm contamination. And we’ve heard time and again from local farms about contamination scares, but actually getting two positives and actually having a real contamination issue is rare.

On the Monday when the alarming red taping happened, a second sample was taken and sent to the lab. But, it takes time to get the results back. We didn’t find out until Thursday that the second test was negative (which we had to hunt down since the State only has urgency for positive tests). This meant that the first test was a false positive. Again, if there were truly a problem, then both tests would have been positive. 

In between Monday and Thursday, a whole lot of hustling happened to make sure everyone got their milk. 
 

  • Thank goodness Aaron’s brother David runs our second dairy farm now. Aaron was over there multiple nights last week bottling milk. 
  • We needed to move Thursday pickup to Friday. This meant that customers, the staff, the drivers, and everyone needed to rearrange their schedules last minute. 
  • The kitchen team needed to put some raw dairy products out of stock for a few days. We never like doing that, but we simply didn’t have enough definitely safe milk.
  • The customer service team had an overload of emails about the change and all that. 
  • There are a lot more little things, too, but I’ll stop here.


And all this for what? A false positive. There was nothing wrong with any of that milk the whole time. Sadly, we had lots of milk go to waste 😔

Don’t get me wrong. Food safety, especially for our milk, is so important to us. That’s why we go above and beyond with our MILK SAFETY STANDARDS

We do much more than the State requires. That includes testing every batch of raw milk on site for general bacteria counts, which is a great indicator of whether our meticulous cleaning practices are happening and working. For better or worse, that also includes telling you stories like this, so you can know everything about how your food is produced.

This is the kind of story that consumers rarely hear. They only hear it when things go awfully wrong and Food Safety News is blasting out “DUMP YOUR MILK” articles that shame farmers or processors. 

In my opinion, government regulation of food safety is ultimately a good thing, but it’s absolutely not perfect (what government agency is, after all). I mean, why red tape after the first test, knowing that false positives are common? If you red tape, then shouldn’t there be a recall, too? Nope, a recall only happens after a second positive test. And why wait 4 days to find out the results? Can’t there be a rush testing facility somewhere? We really need faster results to provide our customers the safest food experience while also making sure our farmers can stay in business.

What do you think? Is food safety something you worry about? Should we sing from the hilltops after a first positive test? Or, should we wait for the second test to confirm it? Are our milk safety standards up to your standards?

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 negative-ish for heavy metals 🥳 NATURAL AND CLEAN

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 pre-soak with apple cider vinegar and simmer for 48 hours to 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. What I glean from this study is that we need more research. 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 got the test results back. I was super excited. But, I was also confused. At face value, it appeared that our bone broth tested NEGATIVE for arsenic, cadmium, lead, and mercury. You can find the test results right here! You'll notice that, for every sample, the results are "<0.01 mg/kg" and "<0.02 mg/kg".  I asked the lab what the "<" means. They said that it indicates their limit of quantitation (LOQ), the lowest concentration that can be accurately tested using the test procedure in that sample type. So the results simply report that none of the metals tested were found in the sample above the specific reporting LOQs. Whether or not they were present below this LOQ is information that is not provided by the test. When talking to the lab, I told them what we needed and assumed that this test would go below a 1 ppb. So, when the results came in, I assumed that a "mg/kg" was the same as a part per billion (ppb). Ummm... that math wasn't write! A "mg/kg" is actually a part per million (ppm). That means that the test we ran had results saying that the broth had less than 0.02 ppm (or 20 ppb) of arsenic and lead. And, it had less than 0.01 ppm (or 10 ppb) of cadmium and mercury. For some reference, the EPA says that less than 15 ppb of lead is safe in drinking water. Not saying that I agree, but it's a good reference point.  These results are good. It means the broth definitely isn't overloaded with toxic heavy metals. But, it's not good enough!!! We need to test again! We really need to a lower LOQ. We need to know the results with an accuracy of as low as 1 ppb. It looks like the lab we sent the original samples to doesn't have an LOQ that low. So here I am on the hunt for a lab to do it again. As soon as I can, I'll send samples in again and paying for more expensive testing to get the info you deserve. Stay tuned! I hope to have the new results in by the end of April 2025.
