When Ben and I first started dating he made a batch of chocolate white chocolate chunk cookies—black and whites he called them. I was having a terrible day at the library, trying to write another section of my master’s thesis. My phone buzzed in my pocket, and I had a text message from Ben.
“I am being domestic and baking cookies. Black and whites. Want to be my guinea pig?”
Sweet! You pretty much can’t find a better excuse to shut down your laptop, pack up your books, and leave the deafening silence of the library—a boy and COOKIES!
Half an hour later I was walking down his hallway. The smell of baking cookies was wafting out of his apartment. He was pulling the first batch out of the oven as I walked in the door.
“Hi! How goes the thesis?”
“Ugh,” I grunted.
“Wanna cookie?”
“Um, yes!”
Delicious. This boy was definitely racking up points on the keep-o-meter.
“So, how much cookie dough did you eat?” I asked, knowing that when I make cookies, I only ever get half the yield because inevitably I eat half the batch in dough form.
“Um, none of it. It has raw eggs. I don’t want to get Salmonella.”
What?! Salmonella is something that I am fully willing to risk for the sheer delight of cookie dough. But that is not the point of my post today.
You see, Ben’s cautionary tactics in avoiding raw eggs are quite common. He was merely following the rules of food safety that we all learned at some point in elementary school. Raw eggs are dangerous. They make you sick. That is what we were brought up to believe.
Now, I am not saying that raw eggs don’t pass on salmonella, because they can. But it is not the egg’s fault. It’s our fault. Well, rather it is the fault of dirty, crowded, and substandard egg farms and packing plants. It is the same with raw milk. Raw milk does not make you sick itself. Careless processing and handling causes it to be contaminated, and only then does it make you sick. But as a society, we are terrified of microbes in dairy, and we think that these bad microbes are inherent in dairy products. I am not sure why dairy has such a bad rap, because clearly, raw dairy is not the only thing that can make us sick.
Peanuts can kill us too. Apparently.
I hate to admit that I am not surprised. It’s tragic that individuals had to die in order for other people to wake up and take a look at some of the gross problems with our industrial food system. I’ve
written before on disease and contamination in industrial processed food, and I mentioned that the need to seriously re-vamp the way our food system works is not only an issue of public health, but it is also one of national security (as argued by
Michael Pollan).
However, I am not going to talk about the peanut recall today, nor about food and national security. Rather I want to go back to cheese and point out a certain irony: the FDA does not allow the sale of un-aged raw milk cheese in the United States because it is a potential bio hazard. But in the past year, how many people in our country have died from tainted spinach, tomatoes, and now peanut butter?
Yes, of course raw milk cheese can carry deadly pathogens, but so can peanut butter, clearly. So why outlaw raw cheese and not peanut butter?
Heather Paxson, a brilliant anthropologist at MIT, calls this type of query an issue of “microbiopolitics”—a term she coined to “call attention to the fact that dissent over how to live with microorganisms reflects disagreement about how humans ought to live with one another.” In other words, how the politics of dealing with microbial health standards reflects the politics of our society in general.
This post, however, is about cheese, not peanut butter. Even if we just stay in the realm of dairy there are plenty of microbiopolitical issues to discuss. First off, pasteurization.
The claim: Pasteurization stops and kills the undesired spread of milk-borne pathogens, pathogens that used to kill thousands of people. Now, people don’t get sick from milk or dairy products because of the modern marvel of pasteurization.
Counterclaim: Pasteurization destroys nutritional value and makes milk taste bad.
The truth: Both of these claims have some truth and some, um, questionable assumptions.
First of all, pasteurization does not necessarily destroy nutritional value. Milk still contains a great deal protein, and pasteurization does nothing to change that. However, there are also many types of bacteria in milk that may actually be good for you, and when you pasteurize, you kill all the bacteria and microorganisms, good and bad. This is means that you do not get the health benefits of what good bacteria may be there. I have even heard that some people who are generally lactose intolerant can drink raw milk. Scientists think that the beneficial bacteria aids in the breaking down of lactose. That is only speculative, but still interesting. Nonetheless, pasteurization does not make milk non-nutritive, but it does kill off some possibly potential health benefits.
Second, the flavor factor may not have to do with pasteurization, per say. Rather, the flavor of the milk depends first and foremost on the quality of the milk. That being said, all types of pasteurization are not created equal. In my previous post on the
politics of pasteurization I explained the difference between “good” pasteurization and “bad” pasteurization. Basically, “good” pasteurization is trickier and more time consuming, but results in killing any unwanted germs while not “cooking” the milk. “Bad” pasteurization basically blast heats the milk super fast, and then cools it down supper fast, so that you kill all the little nasties, but basically cook the milk, which completely alters the flavor.
Obviously, “bad” or “flash” pasteurization is much easier and more cost effective, so the majority of milk that you will find in the super market is flash pasteurized. However, if you are lucky enough to buy milk at a farmers’ market, or at a grocery story that carries milk from smaller dairy farms, you will find that you milk tastes sweet, as it should. It has an entirely different flavor profile, and while this may have to do with the fact that it is carefully pasteurized as opposed to flash pasteurized, it more likely has to with the fact that the milk comes from happy cows. Seriously.
You see, good milk comes from happy cows. Just as good wine is a snapshot of the weather and soil that the grapes grew in, and just as honey is a freeze-frame of the flowers that the bees feasted upon that season, milk should be a reflection of the different grasses and clovers and flowers that they cow happily munched upon. So it makes sense that the milk from a cow who is out at pasture, dining on sweet clover and green grass, will taste infinitely better than milk from a cow that is squashed in massive corals, knee-deep in its own feces, injected with artificial hormones and anti-biotics, and fed schlep made from corn, soy, and reconstituted waste. The logic is common sense if you stop to think about it. I promise that I am not being overly romantic about happy cows. Not only are happy cows happy (which is very nice), but they also produce tastier and healthier milk.
And how does this translate to cheese? Well, that is quite obvious. Good cheese comes from good milk. So this whole fuss over raw-milk cheese is a little more complicated than just saying that un-pasteurized cheese tastes better. Because, you see, yes, the pasteurization process does affect the flavor of the cheese, but what will more profoundly affect the yumminess of the cheese is the quality of the milk. Higher quality milk, meaning milk from small dairy farms with happy, pasture fed cattle, is either less likely to be pasteurized, or if it is pasteurized, it is done in the careful, “good” way.

So onto the “microbiopolitics” of the matter.
Pasteurization does stop a lot of disease, but it is merely a band-aide for a wound that could be prevented in the first place if we had smaller and cleaner dairy farms that paid more attention to the quality of the milk over the quantity.
This is what is so interesting to me. Even if you pasteurized milk, it can still be contaminated after the pasteurization process, like what happened with the peanut butter. Obviously, we do not pasteurize peanut butter because, well, peanut butter comes from peanuts, and not from a living animal. But still, due to dirty, sub-par processing facilities, the peanuts in that plant in Georgia were contaminated with Salmonella.
The problem with microbes in our dairy is not a problem with the microbes. It is a problem with the care we take in distributing our food. We run into these contamination problems not because of the foods we eat, but because we now heavily rely upon huge, massive, industrial plants that are more concerned with the bottom line—quantity instead of quality. This does not only potentially harm the consumer, but it is obviously harmful to the animals involved as well.
Clearly, pasteurization also is not a magic cure, because why then is un-pasteurized cheese perfectly legal in Europe? In fact, many of the cheese shops that Ben and I visited on this past trip to England did not sell cheese made with pasteurized milk. I must have looked a bit of an idiot as I stood there asking the cheese monger, “And this cheese? Is this made with un-pasteurized milk? And this one? What about this one?”
“They are all made with un-pasteurized milk, dear,” replied the lady at the
Chester Cheese Shop.
Oh. I see. This is not due to any sort of snobbery on the part of the Cheese Shop. No, this is simply because in this small cheese store, the owner only carries cheese made on small farms around the UK, and all of these farms simply don’t pasteurize their milk. And this cheese…this cheese was some of the best cheese I have ever tasted. Was it good because the milk was raw? I don’t know. Maybe. But I think that more likely it was because the milk was just good quality milk from happy cows.
Eating amazing cheese in England made me start to ponder the politics of pasteurization. As I thought more and more about it, I began to see that the politics of pasteurization are wrapped up in so many other political and cultural elements of US society. Once again, I find myself asking somewhat unanswerable questions…all issues of “microbiopolitics.”
If raw milk cheese is perfectly legal under EU regulation, why are we so terrified of it in the United States? And why did dairy get such a bad rap over here? Why are we terrified to eat raw milk cheese, or drink un-pasteurized milk, but we gobble down raw fish in sushi restaurants all over? Why do we assume that products like peanut butter are free of microbes and germs? And if you want to go even deeper, how does our fear of germs and microbes in our food reflect the politics and mindset of our society? Heavy sh*t man…
If you are curious about more issues related to microbiopolitics, I sincerely recommend that you read
Heather Paxson’s work. It is brilliant. Her ethnographic research is absolutely fascinating, as are the conclusions she draws from it.
I could continue to talk about cheese for ages, and there are so many other interesting intricacies and cultural elements to delve into. But I don’t want to bore anyone with too much cheese. As
my brother found out on his last trip to England, too much cheese can be a bad thing…for your digestive system at least.
