New Avenue For MRSA 'Superbug': Pigs 135
smitty777 writes with news that researchers have discovered another way methicillin-resistant Staphylococcus aureus (MRSA) bacteria are developing resistance to antibiotics. According to the study (abstract), the bacteria made the jump to pigs on livestock farms, developed greater resistance through the rounds of antibiotics commonly used to keep the pigs healthy, and then jumped back to humans.
"The important development in the story of ST398 is its move back off the farm into humans, causing first asymptomatic carriage in that original family, and then illnesses in other Dutch residents, and then outbreaks in healthcare settings, and then movement across oceans, and then appearance in retail meat, and then infections in people who had no connection whatsoever to farming—all from an organism with a distinctive agricultural signature. That’s an important evolution, and an illustration once again that, as soon as resistance factors emerge, we really have no idea where they will spread. So it would be a good idea to take actions to keep them from emerging, or at the very least to implement surveillance that would allow us to identify them when they do."

One reason I became a vegetarian was because I learned about all the antibiotics in Pork/Beef/Poultry. I suffered severe Streptococcus infections in the respiratory system. When learning I was effectively on Antibotics, constantly, due to my diet, thus prescription antibiotics were having no observable effect, I realized I was fighting Streptococcus which was already resistant, thus I was getting these painful and long duration infections.
Understand this: Antibiotics are targeted toxins, most likely to have a greater effect upon certain organisims, while there would be some collateral effect upon the host, including degradation of the immune system.
After about 2 years without antibiotic-laden foods I found I stave off these infections more effectively and when I have them the duration is significantly decreased.
Keeping like livestock (or plants) in a dense concentration provides an ideal breeding ground for organisms to prey upon them, further, to mutate as the turnover can be far more rapid than in the wild.

The best way to select for antibiotic resistant bugs (on humans or any other animal) is to continually subject them to an antibiotic-filled environment (hospitals and farms). The story of resistant bacteria jumping from host to host, from farm to people vice versa, across the ocean, etc. doesn't seem particularly surprising. There are plenty of examples of bacteria & viruses moving between species. And, with global trade and travel, it's just a matter of time before diseases spread all over.

Actually there is a mechanism. One of the big companies tried to insert a gene into brazil nuts (either BT or herbicide resistance) and found out that it produced an unexpected immune response because of the way the protein was folded. They abandoned the project, and wrote an article about it in the New England Journal of Medicine, which I read. That's the poster child of the anti-GM movement.
I'm not particularly worried about GM food. I eat GM cornflakes every day (as I found out afterwards). I couldn't avoid GM food if I wanted to. And I do get annoyed when I see the truly stupid arguments against GM food by political science majors who never took a biology course.
But give the critics their due. We in the US turned our entire corn and soybean production into GM crops without notifying consumers about it, and without letting them make their own decisions as consumers who supposedly rule this wonderful free market. There was no labeling and food processors weren't even allowed to sell their food as GM-free for years. Monsanto may believe in a lot of things but they certainly don't believe in a free market.
You can't even get GM-free food in this country any more because the GM strains have contaminated everything else, and when the food companies try to sell grains to Europe, where there are restrictive laws, they're forced to go to the international trade commission and ask (or rather demand) that they be allowed to define food with no more than 1%, or 0.1% (or whatever) GM food as GM-free.
You believe in science? The scientific method says that you have to take your hypotheses and beliefs, and subject them to confirmation in the real world. If you believe that GM food is safe, you have to prove it with data. That's not as easy as you make it out to be. It's not enough to feed a hundred mice for 6 months and see if any of them keels over. It's not even enough to feed 300 million Americans GM corn and soybeans for 20 years and see if any of them keels over, as we did. It is actually impossible to prove generically that GM food is safe. You have to take each specific food.
Let's suppose you're really, really smart and you thought really, really hard, and you couldn't think of a plausible mechanism by which GM food can do harm. That doesn't mean there isn't one. Nobody would have thought that inserting a BT gene into brazil nuts would produce an immune reaction, but it happened.
I don't care how smart you are -- you don't understand the human immune system well enough to predict what can go wrong, because nobody understands the human immune system well enough to predict what can go wrong. That's why that contract lab in England injected a half dozen test subjects with a new drug that caused an unexpected autoimmune reaction and caused one kid to lose his fingers a few years ago. I was taught that proteins were all destroyed in the digestive system, but then I saw in the New Scientist that some of them do survive. What can they do?
I went to a meeting where a scientist from the Natural Resourced Defense Fund made the case that GM foods might cause unexpected immune reactions. I thought it was bullshit.

Because the meaning I was trying to convey was that it's silly to say it can't poison you, unless there's some magic going on that I don't know about, I'm sure it could if genes for belladonna toxin generation were put into a food crop, to give a silly example.

pesticides, GMOs and processed foods
Processed foods I'll give you. People really should move back to whole foods, preferably vegetables, in place of highly processed grains and sugars. Pesticides have their place. There's a lot to be said for moving more toward IPM strategies than we currently have, sure, but they are a necessary evil. Heck, even plants produce their own pesticides. They don't make those secondary metabolites for the fun of it. And it's funny that you mention GE crops as a problem in the same sentence as pesticides, considering the effects [nature.com] they've had on pesticide usage. There's plenty of criticisms to make about how people eat and how food is grown. Processed foods are one. Monoculture & lack of biodiversity, over-fertilization & run-off, water scarcity & depleting aquifers, ect. would be much better practices to gripe about, and issues like peak phosphorus, declining agricultural research, and agriculture in the face of climatic issues are also worth considering. Pesticides and especially biotechnology (in and of themselves anyway) are not...not that pesticide use shouldn't be reduced where possible.

Pesticide we use are far safer the not using pesticides.
I have yet to find some who thing we should stop to have even rudimentary knowledge of things like half-life, dosage, absorption. That is the most BASIC information you should have before forming an opinion.
But , you know, that's hard. SO we will continue to march along with opinion based on books in the 70s that had no science behind them.

Yeah, that's true too. There are bunches of regulations on how long before harvest you can spray for any given pesticide, and by the time you eat it, the amount left over isn't something I'd worry about. When people complain about pesticides, they rarely take that into consideration (and by rarely I mean I haven't actually seen it happen yet). It's always nice to minimize inputs if you can do so while keeping the output constant (especially if you're a farmer and those sprays are coming out of your botto

The GP actually has a point even though he fails horribly to put it forward in any constructive manner. The argument is that keeping animals for food almost inevitably results in them being more likely to contract diseases due to living in closer proximity to one another. Furthermore, because humans handle these animals frequently, the risk that a new and nasty pathogen can jump from animals to humans increases. While excluding animal products from our food chain would not completely eliminate the risk of i

You can actually be a perfectly healthy vegetarian; but you need to be smart and knowledgable about your diet.
Jack la Lane was a vegetarian, and who could probably kick most people ass, and rarely got sick.
He was intelligent about how he ate, and he exercised every day.
Most vegetarians just eat anything as long as it's not meat,and don'r exercise.
Oh, he did start eating meat when he was around 65, or so. There wasn't any other way to get certain fats an elderly person needs. Once again, he was smart about his diet.
I am not a vegetarian, but I would like to see people pull back on meat portions. Cause there is a difference between eating meat, and eating a pound or more of meat a day.

That is an outdated thought process that lost all credibility before bell-bottoms did. Humans can synthesize all of our protein requirements as long as we get the basic amino acids. Tofu and quinoa are both complete proteins, and you'll find that most, if not all, vegetarians eat both of those. With a simple mix of rice, bread, and legumes (which you're eating as a vegetarian) you're going to get all your aminos. You don't have to plan it at all nor do you have to "blend" proteins to get them all in on
