What does the farmer do to verify his milk is safe?

The farmer is a raw milk farmer, and safety is a top priority.

According to the CDC and FDA, drinking raw milk puts you at risk of exposure to a wide range of bacteria including Brucella, Campylobacter, Tuberculosis, E. coli, Listeria, and Salmonella.

Where would these harmful bacteria come from?


If a cow is sick, those bacteria or viruses can make their way into the milk.

If the milking equipment is not clean, it may harbor harmful microorganisms.

Or, let’s say the farm staff are not careful, the milk can be exposed to dirt or other contaminants.

So, what does the farmer do to verify that his milk is safe?


First, he makes sure his cows are healthy. This means feeding them a natural diet of 100% grass and allowing them to live an active lifestyle at pasture. This also means knowing his cows and caring for them if they become ill.

Second, he makes sure his cows’ teats and udders and the milking equipment are spotlessly clean.

Third, he makes sure his staff are properly trained on safe handling of milk.

Fourth, he is certified by the PA Department of Agriculture for raw milk production and bottling. They are responsible for inspecting his facility and testing his cows and milk bi-annually for harmful bacteria.

But, if you know our farmer, you know he goes above and beyond. This is why he also tests every batch of milk on site.


The farmer invested in on site testing supplies last year. He test every batch of both the bulk tank milk and bottled milk.. This is not required and certainly not the norm for raw milk farmers.

The on site testing measures TCC (total coliform count) and SPC (standard plate count). These tests show the general bacteria count of the milk, not specific pathogens. However, it does give a good measure of how “clean” the milk is.

If a test comes back higher than normal, the farmer can immediately diagnose the issue and resolve it for the following week.

A2 beef vs A2 dairy. What's the difference? One doesn't even exist in the US.

Every once in a while, a customer sees that we offer A2/A2 dairy and asks, "Do you sell A2 beef?" When this happens, I let them know that A2 beef isn't a thing... at least not in the United States. But, A2/A2 dairy is. The dairy vs. beef classifications are based on two completely separate things. One has to do with marbling in meat, and the other has to do with the type of protein in milk. Here's the explanation of both.

What's in our natural egg feed? And why is it in there anyway?

Our egg farmers recently switched to a new, natural, and 100% honest feed supplier. We are thrilled that they'll work with us to create a corn & soy free feed that fits our natural requirements. Here are answers to common questions about the feed as well as the nitty gritty details about the feed ingredients.

Egg yolk changes. We were greenwashed and are furious! Here's the scoop.

If you've followed our blog for some time, then you know that I do a good amount of muckraking on the food industry - conventional, organic, or otherwise. But, this week, I need to rake the muck on us (more specifically on our corn & soy free eggs)! Here's the scoop and everything you need to know about us formulating a new feed with a trusted source.
