This rather interesting study tracks the movement and evolution of antibiotic resistance from hog cesspools (lagoons) caused by factory production (hog farming) of pig meat. You see, in order to pack that many hogs together and not cause them to keel over and die from disease, they have to be pumped full of antibiotics. Guess where the antibiotics end up? In their “refuse”.
As always, I leave you with The Meatrix if you want to know more about factory farming.
Antibiotic Resistance Tracked From Hog Farms to Groundwater
The routine use of antibiotics in swine production can have unintended consequences, with antibiotic resistance genes sometimes leaking from waste lagoons into groundwater, according to new research from the University of Illinois.
Researchers report that some genes found in hog waste lagoons are transferred, “like batons,” from one bacterial species to another. This migration across species and into new environments sometimes dilutes, and sometimes amplifies, genes conferring antibiotic resistance, they say.
The new report, in the August issue of “Applied and Environmental Microbiology,” tracks the passage of tetracycline resistance genes from hog waste lagoons into groundwater wells at two Illinois swine facilities.
Tetracycline is widely used in swine production. It is injected into the animals to treat or prevent disease, and is often used as an additive in hog feed to boost the animals’ growth.
Its near-continuous use in some hog farms promotes the evolution of tetracycline-resistant strains in the animals’ digestive tracts and manure.
This is the first study to take a broad sample of tetracycline resistance genes in a landscape dominated by hog farming, said principal investigator R.I. Mackie, a professor in the University of Illinois-Champaign department of animal sciences and an affiliate of the Institute for Genomic Biology.
It’s well known that occupational exposure to various pollutants including pesticides, manufacturing raw materials, and in this case, flavoring agents, is a serious problem affecting millions of factory and farm workers all over the world.
Which is why it is interesting when one case of a man contracting an illness possibly linked to at-home diacetyl exposure makes much more splashy news than the well documented cases of many workers dying of such exposure at work. It is unfortunate, but people working at factories and in farms are somehow expected to handle higher levels of exposure and risk. The assumption is that they are protected by agencies such as OSHA, and that they will provided with protective wear, etc. But, when the agencies drop the ball on protecting workers, it takes an “escape” of the incident into the ambient realm for the news agencies to pick it up as a headline.
I guess the good thing now is that this diacetyl issue is blown open, and should result in reform, because alternatives are available.
Doctor Links a Man’s Illness to a Microwave Popcorn Habit – New York Times
A fondness for microwave buttered popcorn may have led a 53-year-old Colorado man to develop a serious lung condition that until now has been found only in people working in popcorn plants.
Lung specialists and even a top industry official say the case, the first of its kind, raises serious concerns about the safety of microwave butter-flavored popcorn.
“We’ve all been working on the workplace safety side of this, but the potential for consumer exposure is very concerning,” said John B. Hallagan, general counsel for the Flavor and Extract Manufacturers Association of the United States, a trade association of companies that make butter flavorings for popcorn producers. “Are there other cases out there? There could be.”
A spokeswoman for the Food and Drug Administration said that the agency was considering the case as part of a review of the safety of diacetyl, which adds the buttery taste to many microwave popcorns, including Orville Redenbacher and Act II.
Meanwhile, ConAgra, the biggest manufacturer of popcorn, announces plans to drop diacetyl at some undetermined “later date”. Weird, their website’s currently down!
This well designed and well executed study provides rather conclusive proof that High Fructose Corn Syrup, the sweetener most commonly used in North America, makes you gain weight in a way not explained by calories alone. These rats gained more weight on HFCS compared to a sucrose (regular sugar) diet even though they were fed the same calories. The effect was seen in the short term and in the long term, and abdominal fat increased the most. Gut fat, if you did not know is related to the infamous metabolic syndrome, causing diabetes, hypertension, coronary disease, etc.
High-fructose corn syrup (HFCS) accounts for as much as 40% of caloric sweeteners used in the United States. Some studies have shown that short-term access to HFCS can cause increased body weight, but the findings are mixed. The current study examined both short- and long-term effects of HFCS on body weight, body fat, and circulating triglycerides. In Experiment 1, male Sprague–Dawley rats were maintained for short term (8 weeks) on (1) 12 h/day of 8% HFCS, (2) 12 h/day 10% sucrose, (3) 24 h/day HFCS, all with ad libitum rodent chow, or (4) ad libitum chow alone. Rats with 12-h access to HFCS gained significantly more body weight than animals given equal access to 10% sucrose, even though they consumed the same number of total calories, but fewer calories from HFCS than sucrose. In Experiment 2, the long-term effects of HFCS on body weight and obesogenic parameters, as well as gender differences, were explored. Over the course of 6 or 7 months, both male and female rats with access to HFCS gained significantly more body weight than control groups. This increase in body weight with HFCS was accompanied by an increase in adipose fat, notably in the abdominal region, and elevated circulating triglyceride levels. Translated to humans, these results suggest that excessive consumption of HFCS may contribute to the incidence of obesity.
For a more layman friendly summary of the article, read the sciencedaily release.
Do reconsider your food habits to avoid HFCS. Note that this whole corn syrup boondongle is made possible by the US government’s insistence on providing billion dollar subsidies to its farmers to grow corn while imposing tariffs on cane sugar from the tropics to make it less attractive. Free trade, my A$$.

As barriers go, it’s unimpressive, a line of railroad timbers cutting across a parking lot off West Franklin Street. But, symbolically, it’s a miniature Mason-Dixon line.On one side is gray-haired Southern land baron P.H. Craig. On the other, Long Island Yankee Spencer Young III.
Young, 51, owns The Courtyard of Chapel Hill, home to the popular Mexican popsicle shop Locopops and restaurants Penang and Bonne Soiree, 3Cups coffee, wine and tea shop and Sandwhich sandwich shop.
Craig, 70, owns most of the parking lot that serves the Courtyard. About six months ago, Craig blocked off his section with railroad ties and gravel piles. The Courtyard’s parking dropped from 79 spaces to 23.
The move, which Young calls “Machiavellian,” has hobbled his tenants, bothered customers and dragged public officials into private matter.
newsobserver.com | Chapel Hill parking lot now no man s land
It’s always interesting and frustrating to me when the property rights of one man triumph over the obvious welfare of the town. The Supreme Court in Kelo v. City of New London did uphold the principle that privately owned property could be forcibly sold to another private entity if it was part of a “comprehensive redevelopment plan”. Clearly, the town of Chapel Hill is going to do no such thing. Not that a giant open parking lot occupying valuable real estate space is any better, but Chapel Hill downtown seems to be owned by well heeled landed gentry always holding out for more money. If they asked me, I would try to get more people to live there, I would get the university a bigger foothold downtown, as my planner friend always says, instead of building a giant outpost campus. There’s little to do downtown other than eat, drink, or buy UNC paraphernalia. But who knows, city planning ain’t my area of expertise. But I have lived downtown for the past 5 years and all I ever did in downtown Chapel Hill was drink (lots), eat (occasionally), fix my bike (a couple of times) and buy a T-Shirt (once). So something is not right.
Meanwhile, the reporter tries very hard to re-enact the American civil war, only in the South!
Right, a brawl involving valuable real estate space and business that boils down to cultural differences, not money, sell me something else brother!

NC Warn produces a good cheatsheet on Duke Energy‘s deceptions about the Cliffside coal fired power plant.
For more than a year, Duke Energy has tried to sell the idea that building a large coal-fired power plant near Charlotte would somehow be “good for the environment.” Following the January 29th state approval for construction to begin, the deception increased. By masking the new unit’s pollution behind upgrades already required by state law at an existing Cliffside furnace – and the retirement of four very small units that sit idle most of the time – Duke has misled the public, media and elected leaders into thinking that building a new unit will reduce a range of harmful emissions.
GreenscamAlert-AMythFactHandout
To summarize, CO2 emissions are set to increase significantly (factor of 12) if this plant is approved. So, in my book, this is a loser project that does not deserve even consideration. The facts are simple. This country is less than two years away from putting a price on carbon through some kind of carbon cap-trade scheme. All three major candidates for president support some kind of scheme, though McCain does not seem to know if the legislation he supports has an emissions cap or not (typical of him, he does not have any policy expertise or attention to detail whatsoever). So, the ground rules on what constitutes a cost effective option and what represents a major money making boondoggle are going to change very soon. Our state officials, thanks to the miracle of the internets, have all the knowledge to make a decision based on a reality that is coming soon. So, their reluctance to consider CO2 is puzzlingly short sighted. Duke Energy has some vague promises to sequester the carbon. But the fact of the matter is that the technology does not exist, and there’s no guarantee that it will exist any time soon in any cost effective fashion.
Even if you’re a big believer in the technology advances that will no doubt occur into the future, you have to admit that carbon emissions cannot be free any more. So, unless the federal government puts a price on the carbon, you cannot objectively support a project that will give these emissions away for free. Don’t tell me that Duke Energy will have to pay for the carbon it emits from Cliffside. It may have to, but it will pas all costs along to consumers and win anyway. So the tax payers of North Carolina are stuck with an expensive, dinosaur technology power generating option that is incredibly polluting for years to come. All because the state officials did not have the foresight to wait a year or two.
You can make the same argument for mercury. The current EPA “plan” for mercury is in tatters as it violates the clean air act. A change in administration (no McCain this time, only Clinton or Obama) is no doubt going to cause a tightening of mercury rules, a long overdue prospect. Why would the state approve a plan that would result in an increase in mercury emissions knowing fully well that federal regulation in this matter is unsettled? What ever happened to the conservative wait and watch approach?

It turns out that turning up the heat on popcorn manufacturers to replace diacetyl, the artificial butter flavoring ingredient that kills people exposed to it during manufacturing, has effects. Apparently, there are substitutes that work just as well and can be used without too much trouble.
Popcorn Maker Drops Chemical Linked To Lung Ailment – Local News Story – WRTV Indianapolis
Weaver Popcorn Co., one of the nation’s top microwave popcorn makers, has switched to a new butter flavoring, replacing a chemical linked to a lung ailment in popcorn plant workers.
The Indianapolis-based company began shipping new butter-flavored microwave popcorn a few weeks ago that contain no diacetyl, a chemical undergoing national scrutiny because of cases of bronchiolitis obliterans, a rare life-threatening disease often called popcorn lung.
Company president Mike Weaver said that although his workers have experienced no such cases, the family-owned business wanted to lead the popcorn industry and allay consumer fears by eliminating the chemical from its product line
David Michaels of George Washington University’s Scientific Knowledge and Public Policy Project and writer on one of my favorite blogs, the Pump Handle has been at the forefront of documenting this issue, raising awareness and bringing pressure to bear. I am glad to see that we’re seeing positive change for diacetyl.
Hopefully, you’re going to start seeing “Diacetyl Free!!!!” signs on your microwave popcorn (and other artificially buttered products) real soon.
