What I am going to say is people should be able to choose to avoid it if their little hearts desire. According to this article, some people (with ties to the drug's largest producer, oddly enough), are lobbying to stop "hormone-free" labels.
I could understand, if there were local regulations banning the use of an FDA-approved drugs, lobbying to remove those regulations. Trying to create a regulation against a label that says you don't use those drugs? Unnecessary, wasteful, stupid! Allow people the choice. Maybe this means you lose your market, but that's how capitalism works (at least, in theory): informed people choose where to spend their money. If you can't afford to produce rBST-free milk at the price offered and you can't sell non-rBST-free milk, you need to get out of the dairy business.

I was not amused by this article. This is fear-mongering, fueled by the fact that most people don't know their burgers are coming from dairy cows (I've never met a layperson who knew that; they're always a bit shocked). The understanding of epidemiology here is particularly egregious:
One: why mention all these "terrible" diseases if they aren't entering the food chain? Two: hate to say it, but milk is a bigger risk than beef for MAP transmission (MAP is the cause of Johne's disease, and is under debate as a contributing factor in Crohn's disease), so I'd rather have them at the slaughterhouse, where the risk of contamination is minimal, than in the milking parlor.
Dairy cows can also carry some common maladies, including mastitis, a bacterial infection of the udder; foot rot, which they can develop standing for long periods in manure, mud and damp straw; and Johne’s disease.
Scientists believe these diseases are not carried into the human food chain, with one exception: Health and animal scientists are currently debating whether the traits of Johne’s are responsible for Chron’s disease in humans. Chron’s disease is an intestinal disorder that can cause inflammation of the colon, severe abdominal pain, diarrhea and weight loss. Some argue it’s these very problems that prompt farmers to dispatch the cows to the slaughterhouse in the first place.
Lesson: don't get your information about your food from the editorial page!
I was very amused by this article. USDA inspectors may not have been doing their job, but that's really no excuse for the Humane Society avoiding their legal responsibility . . . and why were they contacting local DA, then releasing the video on YouTube with national promotion? Sounds like they wanted to appear to do the legal thing while making the biggest publicity. Shame on HSUS!
WASHINGTON — Congressmen repeatedly questioned a representative of the Humane Society of the United States on Tuesday about why the group did not immediately inform USDA of video evidence workers were abusing downed cattle at Hallmark/Westland Meat Packing Co.
Humane Society grilled on not advising USDA about Hallmark By Janie Gabbett on 2/26/2008 for Meatingplace.com
At a House Energy and Commerce subcommittee hearing on food safety, Michael Greger, HSUS director of public health and animal agriculture, said the San Bernardino District Attorney's office asked the group to hold the information until it completed its own investigation. The congressmen, however, said HSUS could have discretely gone to USDA earlier than it did.
Greger hinted at more HSUS exposes, telling the committee the videographer's identity must be guarded so as not to compromise current and future investigations. The Hallmark/Westland video, which was shown at the hearing, resulted in the nation's largest beef recall. (See Hallmark/Westland recalls 143 million lbs of beef — largest in history on Meatingplace.com, Feb. 18, 2008.)
Hallmark/Westland President Steve Mendell did not attend the hearing, declining the committee's request for him to testify. Committee members said they are looking at compelling him to come before the committee sometime in the future.
Greger told the committee that Hallmark workers said in criminal testimony in California that they were pressured by supervisors to get the cows up and into slaughter. Hallmark slaughtered mostly spent dairy cattle, often fatigued after being trucked in from surrounding states.
Members of the subcommittee, which is chaired by Rep. Bart Stupak (D-Mich.), used the hearing as an opportunity to renew calls for: banning all meat from downer cattle from the food supply, mandatory traceability standards, mandatory recall authority for USDA and the Food and Drug Administration and the creation of a single food safety agency.
William Marler, a Seattle lawyer who represents victims of foodborne illnesses, however, suggested USDA might have actually gone too far with the Hallmark recall.
"Although stunned by the video …I am more stunned that the recall has ballooned to 143 million pounds of meat and is quickly encompassing products that might contain trace amounts of the meat. No people have been sickened. I wonder if resources are better spent elsewhere," he testified before the committee.

Smithfield says manure didn't make the grade for biofuel By Janie Gabbett on 2/13/2008 for Meatingplace.com
Smithfield Foods said it sold its Utah biofuels plant because after three years of trying, it concluded it could not generate enough methane from the animal waste it was using to make Smithfield BioEnergy economically practical.
The company explained what went wrong a day after Beacon Energy Corp. announced it had purchased the plant. (See Smithfield biofuel affiliate sold on Meatingplace.com, February 13, 2008.)
The goal of Smithfield BioEnergy was to capture methane from manure provided by Smithfield's Circle Four Farms swine production operation near Milford, Utah, convert the methane into bio-methanol, and then convert that — along with animal and vegetable fats — into bio-diesel fuel.
"However, we determined that our bio-methanol production plant was not economically feasible — and never would be," the company said in a statement.
The facility was designed using engineering and planning assumptions about the strength of the nutrient content of animal manure taken from government data and technical guidance manuals. Those assumptions proved to be wrong.
The nutrient content of the animal manure produced on Smithfield's farms proved to be more than 50 percent below published data estimates, which the company attributed to such factors as:
"The fact that our Circle Four Farms operation is producing fewer nutrients than had been anticipated is a good thing from an environmental perspective, but the unintended consequence is that we don't have enough methane to make our Smithfield BioEnergy operation economically practical," the company said.
- animal genetic improvement
- improved feed conversion
- reduced water volume used in production systems
- and precisely formulated animal diets
Smithfield is applying what it learned to other facilities around the country to reduce its environmental footprint. For example, projects are in place at facilities in Tar Heel, N.C., Plainwell, Mich., and Green Bay, Wis., to capture and use methane as an alternative and renewable fuel source.
Judge rules poultry are not 'livestock' By Alicia Karapetian on 3/5/2008 for Meatingplace.com A San Francisco judge has ruled that chickens are not "livestock," and, as a result, are not subject to the Humane Methods of Slaughter Act, according to court filings.
A lawsuit brought by the Humane Society of the United States against the Agriculture Department argued that USDA had misinterpreted the 50-year-old act.
"The court finds the legislative history strongly demonstrates unambiguous congressional intent that livestock, as used in the HMSA, does not include poultry," U.S. District Court Judge Marilyn Hall Patel wrote in her opinion.
Judge Patel granted summary judgment in USDA's favor and dismissed the lawsuit.
HSUS's argument was based on a 1958 dictionary definition of livestock that said that the word encompassed "useful" animals on a farm, while USDA said that the term livestock has always internally meant to exclude poultry.
"The plain language of these bills indicates that Congress intended to exclude poultry from the definition of livestock when it enacted H.R. 8308, the bill that eventually became the HMSA," Patel wrote.

The idea is that we, as Americans, eat too much meat. I would have to agree. You could say we're biased, the author and I: he wrote a vegetarian cookbook, I was a vegetarian for a few years. Still, my experience is that little or no meat in my diet makes me healthier. His research shows that Americans are eating twice as much protein (mostly animal-based) as the (high-end) recommendation. I think we have an argument.
The environmental issue is a touchy one, but he makes his point well -- we produce far too much manure in concentrated areas to spread on fields (some dairy farms are now leasing fields just to spread their manure). We use a lot of water and energy growing and transporting grain to feed livestock. It's not true that all meat production should be banned; there are places in this world, as mentioned in the article, where grass-fed livestock is the only agricultural option. I've been to a couple of those places and believe me, you wouldn't want to be a vegetarian there! We shouldn't deny people a chance to raise their own food, no matter what the moral guilt of a rich society tells us we should do.
And that's really the point -- we, as citizens of a rich country with a wide range of food options, shouldn't be eating so much meat. What should we be eating? To quote another NYT columnist, "eat food, not too much, mostly plants."

I'll admit -- I like this idea, in part, because it will drive up the price for internationally sourced foods, much closer to local foods, which might give people another reason to support their local farmers!
It is beyond our imagination to even have a theory for why the food is unsafe.Wow. They can't even imagine a theory. Umm, I don't want the people responsible for protecting our food supply (which mostly consists of imagining threats and counteracting them) unable to imagine a theory here. I can think of a few theories. Not good ones, of course, but he didn't say credible theory -- he said they couldn't imagine a theory.
I hope our FDA guys will start improving their imaginations, fast.
