oxide7 writes "The philosopher Frederick Nietzsche once famously said, 'That which does not kill me, makes me stronger.' That may or may not be true for human beings, but it is certainly true for bacteria. The superbugs are among us and they are not leaving. Indeed, they are growing stronger. 'The problem is that the animal agriculture industry makes massive use of low-dose antibiotics for growth promotion and in place of effective infection prevention methods,' Young said, adding that the farm animal population is much larger than the human population. The low-dose antibiotics do not kill the disease. They make the disease stronger, more resistant to those and other antibiotics. The animals — the cattle, pigs and chickens — thus treated become superbug factories. The diseases stay in them and they wash off them to infect the surrounding environment."

GOOD. I hope banning antibiotics in livestock passes. Also banning ag companies from accusing innocent farmers of stealing their gene-modified corn.
This is a perfect example of unintended consequences, where antibiotics cure human disease, but then the germs "fight back" and revive in a more deadly form which we don't know how to stop. I wouldn't be surprised if the 2100s experiences as much death from disease as people in the 1800s did.

Most of the resistance business is about penicillin derivatives, tetracyclines and vancomycin, all of which come from the 1950s or earlier.
Sure, misuse is making those antibiotics less effective at treating diseases, but the other half of the equation is that they have been so effective for 50 years that it hasn't been particularly worthwhile to pursue drugs that use different mechanisms of attack.
Rapid genome sequencing is changing that, expect all sorts of novel antibiotics over the next 20 years. Also expect to pay for them.

Your conclusion is missing a vital piece of data. Vancomycin is the last line of defense for antibiotic-resistant infections in humans. That is why doctors avoid using it -- because it is vitally important that the bugs never acquire a resistance to it.

It's also a perfect example of stupidity. Human beings haven't really been around that long (in fact, according to some Morm^Hons, I was apparently born before the descent of Man), and evolves comparatively slowly.
Bacteria, on the other hand, can easily pick up scraps of extracellular DNA and incorporate it into their own, driving evolution effectively (i.e. where necessary) within a single generation of 15 minutes under optimal conditions. Bacteria might not be as smart as us (though I sometimes wonder), but their biochemistry can be seriously cool, and giving them the advantage in our food chain is just damn silly.
Incidentally, you mention death from disease in the 1800s: It seems to surprise many to be reminded that the Spanish Influenza pandemic (1918-1920) killed more people than the First ("Great") World War. It killed more people in a single year than the Bubonic Plague did in four, from 1347 to 1351.

2) Some farmers let you just buy a side of a cow (or an entire cow). So for $x00 you can buy an entire cow. The farmer raises it, kills it and you can have a say in how it is butchered. This does require a deep freezer (unless you're going to throw one heck of a braai). Usually ends up cheaper than super market and you know exactly where your meat is coming from.

We are both partially right. From http://www.fao.org/docrep/article/agrippa/555_en.htm [fao.org]
According to the National Office of Animal Health (NOAH, 2001), antibiotic growth promoters are used to "help growing animals digest their food more efficiently, get maximum benefit from it and allow them to develop into strong and healthy individuals". Although the mechanism underpinning their action is unclear, t is believed that the antibiotics suppress sensitive populations of bacteria in the intestines. It has been estimated that as much as 6 per cent of the net energy in the pig diet could be lost due to microbial fermentation in the intestine (Jensen, 1998). If the microbial population could be better controlled, it is possible that the lost energy could be diverted to growth.
Thomke & Elwinger (1998) hypothesize that cytokines released during the immune response may also stimulate the release of catabolic hormones, which would reduce muscle mass. Therefore a reduction in gastrointestinal infections would result in the subsequent increase in muscle weight. Whatever the mechanism of action, the result of the use of growth promoters is an improvement in daily growth rates between 1 and 10 per cent resulting in meat of a better quality, with less fat and increased protein content. There can be no doubt that growth promoters are effective; Prescott & Baggot (1993), however, sho ed that the effects of growth promoters were much more noticeable in sick animals and those housed in cramped, unhygienic conditions.
Currently, there is controversy surrounding the use of growth promoters for animals destined for meat production, as overuse of any antibiotic over a period of time may lead to the local bacterial populations becoming resistant to the antibiotic. This is it not an invariable rule: Streptococcus pyogenes remains sensitive to penicillins after over sixty years of clinical use but such examples are, however, very rare. Undoubtedly, the medical exploitation of antimicrobial chemotherapy, particularly to treat human infections, has imposed an enormous selection pressure on formerly sensitive bacteria to acquire genetic elements that code for resistance to antibiotics.

I liked what the Russians were working on for a while - Phages. More completely, Bacteriophages. Viruses for bacterias.
No chance of the virus crossing over to affect humans, and a bacterial colony already under assault by the human immune system isn't generally going to last long when it's also 'sick' with a virus. As a bonus, immunity doesn't really happen because the virus adapts right along with the bacteria.
The problem with phages is that they're the opposite of broad-spectrum antibiotics. They're very, very, specific. They'll clear a throat infection right up, but first you need a culture to determine which species of bacteria you have(there's millions/billions of them), then find an effective phage against it.
That can take a week, then you gotta get the phage to the clinic, as most don't have the room for the number of phage samples you'd need.

However, that cellular mechanism serves a useful function in the cell (usually to bring nutrients into the bacterial cell). When antibiotic resistant bacteria are in an environment without antibiotics they generally die off over a relatively short time-span.

Additionally, as someone with a doctorate in animal science and a researcher in the field, I have to say that the case against animal agriculture is overstated. No one will argue that they don't contribute, but the relative importance of antibiotic use in animals (that less than 1% of the population ever come into contact with while they are alive) relative to that of rampant, large-dose, antibiotic abuses in hospitals (You know where all of those sick people hang out, transferring infections back and forth) has never been ascertained empirically.
First, the vast majority of the bacterial species that live in livestock are not capable of living in people. Therefore, the rate of resistance transfer from animal bacteria to human bacteria is relatively low. Evidence exists that these species can, and do transfer resistance gene between eachother. However, the majority of the evidence is "Resistance gene A is present in pig bacteria and human bacteria, and genes are essentially identical, therefore the gene came from animals!" This of course, completely ignores the possiblity that the gene arose to prominence in the human population and then was transferred to a pig via a farm worker that was a carrier. Talk about placing the cart in front of horse.
Second, low levels of antibiotic use in the swine industry is usually only during the first month after weaning. Pigs are weaned at between 18 and 24 days on most farms in order to prevent the sow (aka "Mom") from transmitting certain diseases to the piglets that have little effect on adult animals, but can kill piglets very easily. At this age the maternal antibodies from the colostrum are starting to wear off, but the piglets own acquired immune system is not completely up to the task. Therefore the antibiotics buy the piglets time by reducing the overall microbial load in the intestine, and coincidentally increasing the efficiency of feed utilization (which is good for the environment). Many farms then discontinue the use of prophylactic, or growth promoting antibiotics because antibiotics cost money and feed costs can account for 60-70% of total production overhead. Expensive feed can drive you out of business in a hurry.
Third, to all those bragging about being from the EU, where there is a total ban on prophylactic antibiotics a word of caution. The total amount of antibiotics used in EU agriculture is not actually lower than it was before the ban. The difference is that instead of giving antibiotics to prevent infection, and improve production they are now given to tread disease outbreaks that wouldn't of otherwise happened and to try and minimize reductions in production. Also, the antibiotics of most relevance to human medicine are not routinely used for growth promotion, but they are used to treat disease outbreaks. So, the total tonnage of antibiotics being administered has not really gone down (it did until they banned them in the nursery which was the last phase of the ban), and the antibiotics being used are MORE likely to also be used in human medicine. Bravo, talk about unintended consequences!
Finally, I fail to see how this made the front page here. It is not the usual fare of geek (no computers anywhere), it is not actually news (this controversy has been around for at least a decade), this article contributed nothing new to the discussion (restates already rampant FUD), and the IBTimes are not exactly the NYTimes or LATimes. The only thing I can see in its favor is that it lets the ignorant "Organic" group say I told you so without any real technical points for those few of us in the field to respond to. The original article is link-bait, plain and simple and

You bring up some valid points and your insight is an appreciated antidote to a poorly executed article.
But (putting GM feed aside), there remains one big aspect about factory farms I cannot get past...
Are the animals experiencing a quality of life which doesn't include standing around in shit?
Then they are no longer animals. They are active meat cultures. They may not be stressed, but I know plenty of fat idiots who are generally not stressed either and their lives are also pathetic compared to free rang

Anyhow, afaik cows and such don't get antibotics for no reason over here in Sweden. Sure if they get sick (I don't know how that affect slaughter though, don't know if you sell the meat if they are on drugs.)
So it's an american (and most likely others) thing.
May be more needed in really small boxes where you can't move at all and everyone is closer to eachother and so on.

Lack of protein and/or necessary combinations of amino acids does that to one's cognitive abilities. Try mixing mushrooms with lima beans. And eat more nuts and sprouts.

What's happened in our country (world...) is pretty simple. Religion and spirituality is a form of science: we observe things, we attribute them to hypothesis. Thus people imagine gods and spirits to control the various functions of the world. Eventually science evolves to explore the physical world as a set of causes and effects, which improves understanding of spiritual issues (meditation etc) and physical issue, but people still

Yeah, here's a little hint: People blindly doing anything without considering the long-term consequences will likely fuck shit up. At least science provides us with the necessary tools to predict and evaluate those consequences.

Yes, in north america and europe but I was in China a few years ago and they sold pretty strong antibiotics OTC. They just recently stopped doing that somewhat; now the person behind the counter has to listen to you list your symptoms first and write a prescription on the spot. Everyone there keeps plenty of antibiotics in stock at home and will take it for a day or two when they have a fever. They're creatin
