rBST: Should we care?


By Sara | 08/15/08 - 7:55am | Comments (2)

As a local foodie, small producer and farmer’s market vendor, I found myself in an odd position in my last post; defending Monsanto. Although I think Monsanto has a less-than-great track record in the PR department, as a scientist, it was relatively easy to post on the facts. As I cruised the internet looking for blogs, articles and op-ed pieces on rBST, most of what I read about why we should oppose the use of rBST was scientifically unfounded and sometimes completely at odds with reality. There are some legitimate concerns about the use of the product, and (believe it or not), there are also some legitimate reasons to support its continued availability.

So, here’s some issues to think about:

Is it ethical to remove from the marketplace a product that is scientifically safe, but has significant public opposition, if its removal raises the prices of a basic foodstuff? Remember that those most adversely affected are likely to be the least vocal and least politically represented. If rBST is withdrawn from the market place, will it also have a corresponding increase in milk prices?

Who bears the cost when farmers use lower efficiency production methods in favor of other factors such as sustainability, animal welfare, or organic? Dairy farmers use rBST because it lowers their cost of production per gallon of milk. I suspect that the first “rBST-free” brands may have paid a premium to farmers for foregoing the use of the product. But, as major processors became “rBST-free”, they simply imposed a restriction on the product’s use without any change in compensation to the producer.

What is the meaning behind the “rBST-free labels“? Last time I researched it, many claims such as “our milk is produced from cows not treated with rBST” had minimal checks to make sure the producers were not using the product. Milk bearing the label is very likely produced on large-scale dairy farms, and no more likely to be organic, pastured, or local than non-labelled milk. And finally, it has been shown to have no less “hormones” than non-labelled milk.

Optimal versus maximal production: Whether it be through the administration of rBST or traditional selection for extreme milk production, there is no doubt that the extra production comes as some costs. Productive life of dairy cattle (the length of time they remain in the milking herd before they become salvage beef) has decreased dramatically as pounds of milk produced per cow have increased. rBST increases production, as does selective breeding. What is optimum? Is it the same as maximum?

So, before you make your purchasing decision based on that “rBST-free” label, or demand that Monsanto pull the product from the market, make sure that your reasons are sound and you are getting what you pay for.

Monsanto divests of Posilac (rBST)-some science


By Sara | 08/12/08 - 1:52pm | Comments (2)

Monsanto recently issued a press release announcing they are divesting of the rBST product. Monsanto states they are not removing the product from the market, but rather looking to offload the business to a different company. In this first of several posts on rBST, I’ll try to provide some scientific background.

rBST or recombinant bovine somatotropin is a synthetically produced hormone that is identical to a hormone produced in the pituitary gland of cattle. In cattle, BST is present in milk at about 10 parts per billion, whether they receive rBST or not. BST is broken down by the digestive tract when milk is consumed. Even when injected directly into pituitary glands in humans, the BST hormone has no effect (this was tried when BST was first discovered, thinking it might be a way to treat growth hormone deficiency in humans).

The FDA’s review of the product, including levels of IGF-1 and BST in the milk concluded that rBST was safe and that milk from rBST-treated cows was indistinguishable from non-treated animals. Much of the original data submitted to the FDA has been subsequently validated in other research.

The recent JADA paper we discussed here also found no biologically meaningful differences in rBST-free, traditional and organic milk. In fact, the few statistical differences were often in a direction counter to what opponents of rBST would have us believe.

A study at Cornell University concluded that the use of rBST reduced the carbon footprint of milk production. It does this through increasing the efficiency with which cows convert feed to milk. Less feed per gallon = less poop, less greenhouse gas and less cows needed per gallon.

Given all the “rBST-free” labels appearing on the shelves though, there is obviously some controversy here: Wikipedia presents a reasonable summary of the rBST issues. The use of rBST does increase mastitis (inflammation of the udder), although this is similar to what is seen in high-producing dairy cows that are not treated with rBST. So, the question is more of how high the production rate is, than of rBST.

Scientifically, I don’t believe there is any food safety reason to base your milk choices on rBST status of the cows that produce it.

Food Choices in the Real World


By Sara | 07/30/08 - 12:50pm | Comments (2)

There’s an interesting discussion going on at one of the leading feminist blogs. It’s about one woman’s frustrations surrounding food choices and feeding her family. In one single post, she touches on enough topics to fill this blog for the next six months: How do you feed your family healthy, tasty, economical and appealing meals that you can afford financially and time-wise? Add to that a desire to make your food choices reflect your values and other concerns such as the desire to eat local, support sustainability and ethical accountability, and it’s enough to make any Mom pull out their hair!

I share these frustrations about food choices. It seems like we have more information at our fingertips than we can process. Add to that the fact that much “information” is actually propaganda and it’s even harder to make intelligent food choices.

I get PO’d by label claims that are confusing, relatively meaningless and designed to take advantage of people’s concerns for their health and desire to be environmentally or socially responsible.

I get frustrated when I talk to my farmer’s market customers who think “eggs from vegetarian fed chickens” means the chickens led a life of total freedom(chickens aren’t vegetarians). I find it equally dismaying to hear people blaming beef or milk for early onset of puberty (studies show the leading causes have nothing to do with either).

Then there’s the whole local versus industrial and traditional versus organic thing. To paraphrase one particularly well-written comment:

In practice, there are some things it is nearly impossible for industrial agriculture to do particularly well. Others fare better. Localizing food production more solves some problems, introduces others; it’s not a panacea. Over all of this also hangs the spectre of energy policy; some of the most productive (at least in some sense) industrial techniques are deeply coupled to assumptions about cheap fossil fuel availability. … local’ is no more a magic word than so-called `organic’, but it has a place in the discussion of how to fix some of the more broken parts of our current agricultural system.

Much of what is in the press or on the web is so slanted toward converting the reader to a point of view, it’s hard to believe anything. And who has the time to do all the research?

My frustrations are exactly why I started blogging here. I find myself on a mission to sort through some of the crap, research and propaganda so other moms, consumers, producers and food industry folks can get a sens of understanding on some very confusing issues.

Big Food vs. Small Food safety


By Sara | 07/28/08 - 3:59pm | Comments (1)

A post comparing airlines and food safety got me to thinking: In general, is large-scale-produced food more safe than smaller-scale production?

One factor that is often not considered when we evaluate small-scale production food safety is “assessment bias”. If Joe’s 2 bushels of homegrown tomatoes from the farmer’s market are tainted with Salmonella, it is likely to go undetected or reported. Even if people got sick and reported the illness it is unlikely his tomatoes would be identified as the source and even less likely it would make national headlines.

I don’t think we have good statistics on real safety measures of small versus large production. Yet, food safety, especially for meat, ranked above quality and price in a survey of local food purchasers in the upper midwest.

There are some things “small food” has going for it with regard to food safety:

  • Accountability. All producers, large and small are accountable. Small producers are usually directly accountable to the consumer. We put our livelihoods on the line each time we sell an inferior or unsafe product.
  • Known source (sometimes). I say sometimes here, because many farmer’s markets sell produce obtained at large terminal produce hubs. Here in Texas, that means that unless you know that your market vendor is growing their own, you may be buying jalapenos and tomatoes from the Rio Grande valley or Mexico (one of the sources for the recent salmonella outbreak).
  • Direct relationship with consumer. Having to look my customers in the eye when they buy my beef or ask me questions about my production, quality and safety practices is more effective than a whole slew of federal regulations.

On the other hand, “big food” is often under more rigorous scrutiny and regulation to ensure food safety. Many types of food have mandatory testing not requred for small and local producers. Many of the regulations and production practices in use were put in place to ensure food safety. Small producers often do not have food safety training or food safety plans.

So, don’t presume that local = safe. Ask questions of your local producer about productions practices, food safety, etc. Ask about sources for produce, handling and refrigeration practices for meat and eggs. When purchasing from a small producer it is up to you to be your own “food safety authority”.

Conventional Vs. Organic Milk: No Meaningful Difference in Hormone Levels


By Down to Earth | 07/24/08 - 1:37pm | Comments (2)

We are pleased to present this guest post from Terry Etherton, who normally blogs here.

In the first peer-reviewed study of its kind, a paper*** published in the July issue of the prestigious Journal of the American Dietetic Association (JADA) reports the results of an in-depth survey study comparing retail milk for quality, nutritional value and levels of different milk hormones, including bovine somatotropin (bST).

Cow2

The study looked specifically at three label claims related to dairy-cow management: conventional milk, recombinant bovine somatotropin (rbST)-free milk and organic milk. The recent trend in misleading food labeling based on agricultural management prompted the study.

While minor differences were observed for the three labels, the differences were not “biologically meaningful.” The authors of the study (including me) concluded that label claims “were not related to any meaningful differences in the milk compositional variables measured.” The only difference among conventional, rbST-free and organic milk is price, according to the study, with milk labeled rbST-free or organic selling for anywhere from $1 to $4 more per gallon than conventional milk.

The study will help food and nutritional professionals respond effectively to consumer questions and perceptions about confusing and deceptive milk-label claims that are designed to differentiate rbST-free and organic milk from conventional milk. The objective of these marketing campaigns it to have consumers pay a whole lot for rbST-free or organic milk when, in fact, they are compositionally the same as conventional milk.

Organic milk less healthy than regular milk?


By Sara | 07/24/08 - 7:43am | Comments (1)

WARNING: Take the headline with a grain of salt.

I came across a blog post claiming organic milk is worse than regular milk, and is in fact dangerous. The blog editor has posted liberally elsewhere about dioxins in organic milk: As background to the quote below, the author states that 80% of organic milk worldwide is Ultra-High Temperature processed.

You get far more dioxins with UHT milk than you do with regular pasteurized milk because more dioxins gets digested instead of being flushed out of the body. This occurs because the micronized fat globules in UHT milk are much smaller. As a result, significantly more dioxins from organic UHT milk get into the bloodstream.

This “news” even made it into the mainstream ag news service to which I subscribe.

BUT-being the skeptic I am, I followed up… The bottom line is that I don’t trust the author. His posts claim milk is responsible for acne, death, global warming and is the biggest cause of illness in the world. He is selling a book called “Organic Milk Myth”, among several other books, all of which seem to be aimed at eliminating milk consumption altogether (to be substituted by the “milks” he’ll gladly sell you the recipes to make). Anyone with that clear an agenda is not going to weigh the often conflicting scientific data. In my book, if you don’t consider the validity of the other side’s viewpoint, your arguments don’t hold much water.

There are some valid points in his posts, however. The main thing of value I see in his writing is a point that I have made here many times. Often people buy organic thinking they are getting something they are not. Most organic milk is produced in very similar ways to regular milk. Many organic milk products are UHT pasteurized where their regular counterparts may not be.

There was a good study published recently in the Journal of the American Dietetic Association (JADA) on nutrient and hormone composition of conventional, rbST-free and organic milk.    More on that soon.
