Has the World Reached Peak Chicken?

On Wednesday, the Northern California animal sanctuary Animal Place will airlift—yes, you read that right: airlift—1,150 elderly laying hens from Hayward, California, to Elmira, New York, in an Embraer 120 turbo-prop.

The pricetag? $50,000.

Right. So obviously, this isn’t the most efficient way to spend your chicken-helping money. It didn’t take me very long to think of some alternatives: For example, you could couple all 1,150 hens off and buy each pair its own home. You could feed 758 chickens fancy organic food for an entire year. You could feed 157 people the very fanciest, most coddled, free-rangest, organic-est eggs ever for a year. You could buy flocks of chicks for 2,500 farmers in the developing world through the charity Heifer International.

Don’t get me wrong—it’s not that I think that these soon-to-be-airborn hens don’t deserve a better life. They come from an undisclosed California battery cage egg operation, and as most people know by now, that is no picnic. Animal Place’s Marji Beach explained to me that once laying hens reach the age of about 18 months, their egg production slows, and it’s no longer economically feasible for egg operations to keep them around. The result is that each plant has to get rid of thousands of “spent” hens every year. What happens to those hens? In most cases, they don’t end up in your chicken soup broth, or even in your cat or dog’s food. That’s because most slaughterhouses don’t accept them—they have too little meat on their bones to turn a profit. Instead, egg producers often kill spent hens with highly concentrated carbon dioxide gas. (That probably costs far less than flying the hens across the country, but it doesn’t appeal to Animal Place, whose website urges visitors over and over again to go vegan.)

When a few other Mother Jones staffers and I heard about all those spent-hens problem, it got us wondering: Has the world reached peak chicken? Considering the fact that Americans eat 79 billion eggs a year, that’s an awful lot of laying hens. And that’s to say nothing of the so-called broiler operations that make chickens for supermarket shelves and fast-food sandwiches and nuggets.

According to UC Davis professor and poultry expert Dr. Rodrigo Gallardo, there are several reasons why the world is eating more chicken than ever these days. “If you think about several years ago, most people at beef or pork because there was more availability and because it was cheaper,” Gallardo says. But chickens have become more attractive as options over time: they’re lean, they’ve been bred over time to produce more meat, and raising them takes up much less land than raising cows or pigs.

That’s not to mention eggs. “If you think about eggs, eggs are cheap, they are easy to consume, they are fun—people can cook them in different ways,” Gallardo explains. “Kids always like them, and they are the cheapest protein you can get from an animal source.”

Exactly how many chickens does the world have these days? we wondered. The answer, we found, is a whole lot—and it’s increasing. Here are a few charts that will give you a sense of the scale of the chicken explosion:

Choosing Green Manicure Options

Photo: Microsoft Office

Manicures are a popular way to treat yourself at the spa or salon, but do you know how to choose a manicure that will be safe for both your body and the environment? A study published in 2012 by the California EPA’s Department of Toxic Substances Control found that many nail polishes still contain potentially harmful chemicals, so it’s important to know what kind of treatment to request from your stylist or what brands to purchase on your own.

At the Salon

Traditional manicures and pedicures use many of the same types of products you might use at home, though brands may vary. Historically, many nail polishes contained chemicals like dibutyl phthalate and toluene, which are developmental toxins, and formaldehyde, which is a carcinogen. These chemicals are often referred to as the “Big 3,” and many brands have eliminated them from their products. Check with your salon to see what kinds of products they use, and if you aren’t satisfied with the ingredients in those products, ask if they would consider switching. You could also bring your own polish with you. Plenty of salons offer eco-friendly services, though, so do some research ahead of time.

Gel and shellac manicures have also become popular recently because they last for two to three weeks without chipping. This type of treatment may be convenient, but it does come with some drawbacks. After the polish is applied to your nails, it’s dried using a UV light, which can cause damage to your skin just like UV rays from the sun. If you do choose this option, be sure to apply sunscreen beforehand.

More Good News on Health Care: Medicare Costs Are Down, Down, Down

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

I’ve written before about my belief that health care costs in the United States have been trending downward for a long time. Not just during the aughts (which everyone seems to agree about), but since the early ’80s. Click here for a refresher.

Last week brought some confirmation of this from the Congressional Budget Office. Michael Levine and Melinda Buntin took a look at Medicare spending per beneficiary over the past three decades and came to a very similar conclusion: “Growth in spending per beneficiary in the fee-for-service portion of Medicare has slowed substantially in recent years. The slowdown has been widespread, extending across all of the major service categories, groups of beneficiaries that receive very different amounts of medical care, and all major regions.”

Their basic chart is below. It starts in 1980, but I think it’s better to omit 1980-82. Inflation was very high in those years, which makes Medicare spending growth look artificially high and the subsequent decline artificially steep. However, consumer inflation has been pretty low and steady since then (at around 2 to 3 percent), so inflation doesn’t muddy the picture much after 1983. I’ve drawn an eyeball regression line starting then and it still tells much the same story:

This is good news, but in fact, it’s even better news than it seems at first glance. There are two reasons for this. First, Medicare plays a big role in setting rates and spending priorities for the entire health care industry. So the fact that Medicare spending growth is slowing down suggests that spending growth in the broad health care industry should slow down too.

The second reason is more intriguing. Levine and Buntin note that there have been two previous major declines in Medicare spending, and in both cases they were driven by legislative changes. But over the past decade, we’ve seen another steady decline with nothing to explain it:

The current slowdown cannot be so easily ascribed to a set of changes in payment policy or program structure. As described above, legislation governing payment rates probably did slightly less to restrain growth in the second part of the decade than it did earlier on.

The financial crisis and economic downturn … do not appear to explain much of the slowdown. First…from 2000 to 2005, the growth in the average payment rate programwide was similar to growth in the CPI-U. Second, we did not find evidence to suggest that beneficiaries’ considerable loss of wealth and reduced income growth significantly affected their collective demand for care. Third, it is not clear whether the recession played a role in reducing the rate at which providers purchased new, cost-increasing technologies. Finally, and in contrast, some evidence suggests that high unemployment during the recession boosted providers’ incentives to deliver services to Medicare beneficiaries by reducing the demand for care in the private sector, though we could not empirically confirm the mechanisms by which unemployment might have had such an effect.

The lack of a single big legislative explanation suggests that there’s something more organic going on. And with Obamacare’s cost controls set to kick in over the next decade, we could be entering a virtuous circle of reined-in health care spending for years to come.

Levine and Buntin acknowledge that there’s considerable uncertainty in their analysis. There are a lot of moving parts here, and the truth is that a decade isn’t really a very long time frame to hang your hat on. (Remember all those economic models that assumed housing prices could never fall because they were based on the previous decade’s worth of data?) And it’s worth keeping in mind that even if spending per beneficiary stabilizes, Medicare is still going to have a lot more beneficiaries over the next half century as baby boomers retire and our population ages.

Nonetheless, evidence is mounting all over the place that the spiraling growth of health care costs, which has been a serious bogeyman for the past few decades, might finally be receding. Since health care costs are by far the biggest component of future concerns over federal spending and federal deficits, this suggests that our future may be brighter than we think.

Valley Fever, Explained

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Cases of an illness known as valley fever have increased dramatically over the past decade. So what is it exactly? And who’s at risk? We went to California’s Central Valley to find out—watch the video above, then read this handy FAQ.

What is it? Coccidioidomycosis—commonly known as valley fever—is a fungal disease. Its spores live in the soil. If the soil becomes dry and dusty, people and animals can breathe it in, allowing the spores to grow inside their bodies.

What does valley fever feel like? It depends. Some people who get valley fever don’t have any symptoms at all; in others the disease resembles a cold or flu. Some develop a pneumonia-like condition from the fungus in their lungs. In rare cases, the fungus disseminates and can even attack the brain. According to the CDC more than 40 percent of people who become ill from valley fever may require hospital visits; the average cost of that visit is $50,000. Between 1990 and 2008 there were 3,089 reported deaths from valley fever, though some public health experts suspect that it was an underlying cause of many more deaths.

Who’s at risk? People who live in or travel to the southwestern United States—where the disease is endemic—are at risk. Within that area, working outdoors—at construction sites, archaeological digs, and other places that involve undisturbed soil—also seems to be a risk factor (though plenty of people who don’t have outdoor jobs—for example, this little girl—also get valley fever). Prisons have been hard hit; 18 inmates in California’s Central Valley have died of valley fever in the past few years, and many more have become ill. The state of California recently ordered the transfer of 2,500 prisoners out of two Central Valley prisons with high incidence of the disease; many of the prisoners set to transfer are black and Filipino, two ethnic groups that seem to be disproportionately affected by the dangerous disseminated form of valley fever. Women in their third trimester of pregnancy and people with compromised immune systems are also at higher-than-normal risk.

How is valley fever diagnosed? That’s one of the problems: In chest x-rays, valley fever is very hard to distinguish from pneumonia or even lung cancer—the fungal masses in patients’ lungs look almost identical to tumors, says Dr. Michael Peterson, chief of medicine at UCSF-Fresno. If doctors suspect valley fever, they can order a blood or sputum (phlegm) test, but outside of the endemic areas many doctors aren’t familiar with the disease. That makes it particularly hard for people who contract the disease while traveling to the southwest to get appropriate care. One small company manufactures a simple and quick skin test, but it’s not widely available yet since the company says it can’t afford the FDA’s marketing fee; Rep. Kevin McCarthy (R-CA), who recently formed a valley fever task force, says he plans to petition the FDA to waive the fee.

Which states have the most cases of valley fever? In general, southwestern states:

How common is it? Increasingly common:

Why is valley fever increasing so quickly? One theory is that climate change is playing a role: As the weather gets hotter and drier, soil gets dustier—which means it’s easier for people and animals to breathe in the fungus. Some people believe that the rise is related to the population boom in the southwest: The increase in cases has occurred in the last decade, during which time millions of people have flocked to that part of the country. Not only are there more people to get sick, there’s also more construction, meaning that workers are moving around the previously undisturbed soil where valley fever spores seem to thrive. Antje Lauer, a microbiologist at California State University-Bakersfield, theorizes that the spores might do especially well in burrows where rodents have stored seeds.

Basically all of my fruits and vegetables are grown in California’s Central Valley. Am I going to get valley fever from my next salad? Probably not. Valley fever spores seem to prefer soil that hasn’t been cultivated, explains Lauer. She theorizes “that in agricultural soils, where there is a lot of additional organic matter from manure or scientific chemical or fertilizer being put into the soil, that the diversity of microorganisms goes up, because the diversity of certain nutrients goes up, and then valley fever fungus can’t compete any more.”

What can be done to prevent valley fever? The short answer: if you live in the Southwest, not much. People who work outdoors can wear special masks to limit their exposures, but for the rest of the population, it’s hard to avoid. As UCSF’s Peterson put it, “The only thing you can really do is in days where there are windstorms, there’s lots of dust in the air, do not go out and do heavy exertion, those kinds of things. Otherwise, it’s in the air.”

Where can I learn more about valley fever? The Reporting on Health Collaborative has a great valley fever series about the communities that have been hardest hit by the disease; the CDC has up-to-date information on incidence, risk factors, diagnosis, and treatment.
