Getting More Farm Antibiotics Data: What Will It Take?

By Leave a Comment

Sorry for the radio silence, constant readers: I’m preparing for the big annual conference of the Association of Health Care Journalists, where I am on the board, and the tasks are piling up. Here’s one of the things that happened last week, while I was off getting ready: The Senate committee charged with oversight of agricultural antibiotic use took up re-authorization of the regulation that delivers data on ag drugs, without allowing any testimony about the negative, unintended consequences of misusing and overusing those drugs.

Fortunately, the House of Representatives provided a partial corrective: Members there introduced a bill that would require better data collection. Unfortunately, that bill is a long way from law — and the re-approval of the FDA regulation is close.

"Sh*t, Just Ship It": Felony Prosecution for Salmonella-Peanut Executives

By Leave a Comment

A pretty extraordinary thing happened Thursday, here in Georgia: A district court in the middle part of the state unsealed a 76-count, 52-page indictment of former officials of the Peanut Corporation of America (PCA), charging them with fraud and conspiracy for knowingly distributing peanut products contaminated with Salmonella.

The 2009 outbreak caused by the contaminated peanuts reached, literally, nationwide. Hundreds of products were recalled; 714 people were known to have been made sick by it in 46 states, one-fourth of them were hospitalized, and nine died, according to the Centers for Disease Control and Prevention. (As with other foodborne outbreaks, in which only a fraction of cases are confirmed by lab analysis, the actual number of victims may be much larger.) While that is not the largest outbreak recorded in the United States — the Salmonella in eggs scandal of 2010 sickened almost 2,000 people — it is definitely large: Most of the multi-state foodborne outbreaks analyzed by the CDC involve fewer than 100 known victims.

The PCA outbreak’s size makes it unusual, but so does the decision to press for prosecution: That happens in very few foodborne-illness cases. But if you read the indictment (which I extracted from the federal PACER system and put up at my Scribd account), you’ll see why the Department of Justice decided to prosecute this time. It alleges a trail of not only negligence — unrepaired roof leaks, ignored rodent infestations — but also deliberate deception which ranged from faked origin labeling to falsified lab results.

Project Update: Resistance (The Film) Has A Kickstarter

By Leave a Comment

About a year ago, I told you about an indie effort to put together a superbug documentary called Resistance. The filmmakers, Ernie Park and Michael Graziano (who made the excellent documentary Lunch Line about school lunch programs), have been traveling around the world since then, meeting victims of antibiotic resistance and talking to health care professionals and researchers about superbugs’ inexorable advance.

And now they are in their last stretch, and — as you do these days — they have a Kickstarter, with 35 days to go.

Antibiotic-Resistant Bacteria Surround Big Swine Farms — In China as Well as the U.S.

By Leave a Comment

I suspect we think of large-scale confinement agriculture as a uniquely American issue. Possibly that’s because growth-promoter antibiotic use, which makes meat-raising efficient, originated in the United States; more likely, it’s because some of the largest firms in that sector — Smithfield and Tyson, for example — are US-based. But public and private research efforts (including the US Department of Agriculture, the United Nations’ Food and Agriculture Organization and the Pew Charitable Trusts) have documented that intensive livestock-raising is increasing in emerging economies such as India and China; as incomes rise, demand for meat does too.

A paper published Monday in the Proceedings of the National Academy of Sciences demonstrates that the unintended consequences of confinement agriculture are occurring in those countries as well. A multi-national team of researchers from Michigan State University and two campuses of the Chinese Academy of Sciences found — well, I can’t put it better than their paper’s title does: “Diverse and abundant antibiotic resistance genes in Chinese swine farms.”

Antibiotics and Antibiotic-Resistant Bacteria in Meat: Not Getting Better

By Leave a Comment

A few days ago, the Food and Drug Administration released two important documents related to antibiotic use in livestock raising, and what the results of that antibiotic use are. I’d say that they released them quietly, except, when it comes to this issue, every release seems to be quiet, never accompanied by the press releases or briefings that other divisions of the FDA use to publicize their news.

The two documents are the 2011 Retail Meat Report from the National Antimicrobial Resistance Monitoring System, or NARMS, and the 2011 Summary Report on Antimicrobials Sold or Distributed for Use in Food-Producing Animals, which is known for short as ADUFA, after the 2008 Animal Drug User Fee Act that mandated the data be collected.

These two reports capture almost all the data we receive from the federal government about antibiotic use in livestock production (which is not the same thing as “all the data the federal government possesses” — there is evidence they receive more than they release). So their annual release is an important indicator for whether antibiotic use in meat production, and antibiotic resistance in meat, are trending up or down.

The news does not appear to be good.

On Writing: Culture Looks Down On These Novels, But You Should Read Them Anyway

By Leave a Comment

Excerpted from a “science scribe” live sketch of our Science Online session. c. Perrin Ireland (@experrinment)

Dropping out of scary diseases and scary food for a moment, and into the (more) personal: This past weekend I spoke at Science Online, a fantastic conference in the Triangle area of North Carolina that brings together the different tribes of science communication — journalists, bloggers, scientists, public information officers, museum curators, videographers and audio artists, on and on — for an adrenaline- and coffee-fueled weekend of brainstorming.

SciO, as it’s called, has been going for seven years; I’ve attended for three, speaking each time on some aspect of writing technique. I love going, even though journalists are a minor tribe within the conference’s loose federation, because attending forces me to think not only about why I write, but about how. The process of writing is something I engage with every day, of course, but I’m not often called on to articulate it outside my own head. Prepping presentations for the heterogenous attendees reminds me to examine attitudes and also techniques that I tend to take for granted.

This year, my Wired colleague and friend David Dobbs, from Neuron Culture over there in the right rail, did a storytelling-technique session that turned out to be really well-received, so I thought I’d reproduce it here for wider sharing. We started from this realization: When we learn to write, we’re told to study the greats. But under our noses — sold in airports and drug stores, argued over in blogs and book clubs — there exists a vast and separate world of published writing to which people are passionately attached. That’s genre fiction — mysteries, thrillers, westerns, romances, fantasy and sci-fi — and it keeps its audiences hungering for more via specific techniques that writers can analyze and learn from.

Our session wasn’t recorded (I should really remember to do that when I speak) but you can find the excerpts we discussed on this wiki page. And here’s a recap, via Storify: “What science writing can learn from crap novels.” We say that, of course, with love. [Read more…]

Why We Can't See Inside Poultry Production, and What Might Change if We Could

By Leave a Comment

 

In the past months, there have been several troubling research reports, from different parts of the world, exploring aspects of the same problem: Multi-drug resistant bacteria are present in chicken, apparently because of the use of antibiotics in poultry production, and are passing to people who work with, prepare or eat chicken, at some risk to their health.

Here are a few of the publications:

Fecal Transplants: A Clinical Trial Confirms How Well They Work

By Leave a Comment

A little more than a year ago, I wrote a piece in Scientific American about fecal transplants — replacing the stool in someone’s colon with stool donated by someone else — as a treatment for the pernicious, recurrent diarrhea caused by Clostridium difficile infection.

I have been a journalist for two decades, and some of my stories have won prizes, triggered hearings and legislation, and caused people to change their minds about significant social issues — but I don’t think anything I have written has ever proved as sticky with an audience as that 1,500-word column. In the 60 or so weeks since it was published, I have heard from more than 100 people — yes, that’s more than 1 per week — who are afflicted with C. diff, believe that a transplant could help them, but cannot find a doctor who agrees that the procedure has merit.

A paper published Wednesday evening in the New England Journal of Medicine may give those patients assistance, and change those doctors’ minds. It represents the first report from a completed randomized trial of fecal transplants, and it finds that the treatment worked much better than the powerful antibiotics that are usually given for C. diff infection — so much better, in fact, that the trial was ended early, because the monitoring board supervising the trial’s execution could not ethically justify withholding the transplants from more patients.

U.K. 'Horseburger' Scandal: Did the Meat Originate in the U.S.?

By Leave a Comment

There’s a very fast-moving story breaking in the United Kingdom this past 24 hours: Millions of pre-made burgers sold by supermarkets in the United Kingdom and Ireland have been taken off the market after the meat they contain was found to contain DNA from both horses and pigs. More than a third of the products tested contained some DNA not from cows, and in individual burgers, the amounts ranged from very small to one-third. (Here are overnight stories from The Guardian, The Independent, and The Telegraph.)

The adulteration was discovered by Irish food authorities; Ireland’s food-safety rules are so tight that they include DNA testing for meat (as highlighted on Twitter by Irish food journalist Suzanne Campbell). At this point, the adulteration has been traced to three beef-processing plants, two in Ireland called Liffey Meats and Silvercrest Foods, and one in the U.K. called Dalepak Hambleton. Silvercrest, a subsidiary of ABP Foods, has pointed to “two continental European third-party suppliers who are the suspected source of the product in question,” and the Daily Mail says the source may be processors in Spain and the Netherlands that supplied a powdered protein, used to bulk up the burgers,  which was supposed to be beef.

The illegal horsemeat may well be of European origin. But if I were a European journalist following this story, I’d look further afield as well. I’d look at Canada, Mexico and the United States, and I’d ask whether it is possible that the horsemeat originated in North America — and whether its risks include not just the non-disclosure of its presence, but undisclosed drug residues as well.

A Government Takes Ag Antibiotics Seriously — But Not Our Government

By Leave a Comment

Matt Rourke/AP

It’s always fascinating to me to see how seriously other parts of the world take the issue of antibiotic use in agriculture, given the long struggle in the United States to get the Food and Drug Administration to act and to get legislation through Congress. The European Parliament has voted down any prophylactic antibiotic use, and China has banned growth promoters.

And last week, the UK Parliament examined the issue for the first time in more than a decade, in a long debate that featured some stinging language by members of Parliament and, it must be said, some inadequate responses by a government agency.

Almost-Untreatable Gonorrhea: Proof That It's Here

By Leave a Comment

If you’ve been following this blog for a while, you might have noticed a thread on health authorities’ growing concern over gonorrhea not responding to the drugs used against it. (And if you didn’t notice you can find those posts here.) A paper published Wednesday evening shows that worry has not been misplaced.

The concern is this: Treatment of STDs in infected people, and programs that aim to keep STDs from spreading from those people to others, rely on drugs that are inexpensive to buy, simple to administer, and work after a single dose and clinic visit. Since the late 1990s, there have been only two drugs that fulfill those criteria: an oral drug called cefixime and an injectable called ceftriaxone (both belonging to the same broader drug family called third-generation cephalosporins). Since the early 2000s, there have simultaneously been signs that resistance to cefixime has been spreading from the Pacific Rim — Japan and Hawaii — to North America, Europe and the rest of the world.

Polio Eradication: The Bad News Continues

By Leave a Comment

When last we left the long asymptote of polio eradication, nine health workers in Pakistan who had been administering polio vaccine had been murdered, presumably by the Taliban or its sympathizers, because polio eradication has been cast by them as a plot against Islam in the wake of a CIA operation which used vaccinations as an attempt to get close to Osama bin Laden.

(If this story is new to you: Yes, really. For background, start with this post, and then read this, this, and this.)

So it’s discouraging to say that, in the past few weeks, the news hasn’t gotten any better — though some additional voices have joined the debate in an attempt to stress to the world how important this moment is.

2012 In The Rear-View Mirror: What You Liked

By Leave a Comment


Happy New Year, constant readers. For the second year in a row, here’s my list of which of my posts (91 in 2012!) most moved you to react. Last year (find that list here), I counted down based on which posts provoked the most comments. This year, Wired installed a tweet-counter — which registers only if someone clicks through from Twitter, but not if the post’s URL is mentioned or RT’d — so I thought it would be amusing to score posts that way this year.

And the verdict is: You care enormously about food policy, but you continue to be fascinated by the emergence of scary diseases — and, to my surprise and pleasure, you care about public understanding of science as well.

The Lost History and Unintended Consequences of the Chicken Nugget

By Leave a Comment

A close look at the interior of a McDonald’s McNugget. Bought, sliced open, shot by me. CC 3.0 attrib-noncomm.

There are things in your life that are so ubiquitous, you never stop to consider them. Traffic signals. Magnets. For me, chicken nuggets. They seem to be everywhere: every fast-food chain, every kids’ menu, every supermarket freezer aisle. I don’t particularly care for them, but I never stopped to wonder where they came from. I assumed, as with so much else in our food culture,  McDonald’s was responsible, and other food producers had followed the McNugget’s market-devouring lead.

Well, yes, and no. As part of my reporting on food policy, I’ve been looking into the history of poultry production — and reading up on what drove its vast post-war expansion, I stumbled across the lost history of the nugget. It appears to have been invented — or at least, originally proposed — by a Cornell professor, 17 years before McDonald’s had essentially the same idea.

The Advance of Ticks: New Areas, New Diseases, and a Weird Allergy to Meat

By Leave a Comment

Following up on last week’s post about the advance of dengue: I’ve been keeping track of new news regarding other diseases transmitted by insects and arthropods, but haven’t had a chance to write them up. So here’s an end-of-year round-up. It’s not cheery (are my posts ever cheery?), but maybe it will prompt some New Year’s resolutions to wear repellents and long pants outdoors. These diseases are no fun.

Livestock MRSA Found For First Time In UK Milk

By Leave a Comment

This paper almost slipped by me. It was published quietly a few weeks ago, and it’s a little eyebrow-raising. From EuroSurveillance, the open-access peer-reviewed bulletin of the European Centre for Disease Prevention and Control (Europe’s CDC): The ST398 strain of MRSA, better known as “livestock-associated MRSA” or just “pig MRSA,” has been found for the first time in milk in England. (And therefore probably in cows, or at least on farms.)

Apparently there has been an ongoing study looking for any evidence of MRSA in UK cows, possibly because of this news from last year (of which more in a minute). Between last January and July, the program tested 1,500 samples of milk from farms’ bulk tanks — that’s the cooler in which milk from a number of cows is collected until it can be picked up by a truck for processing — and found seven of the samples were contaminated by MRSA. All seven isolates were MRSA ST398, the livestock-associated strain. Three came from one farm, so five farms had MRSA in their tanks.  According to the paper, this is the first discovery of ST398 in the UK other than one finding in horses in 2009.

An Old Disease Returns: Dengue Is in Florida and May Be Heading North

By Leave a Comment

This month, Slate has been running an intermittent series on pandemics under the guidance of new science editor Laura Helmuth. The latest entry in the series is one that I wrote (my first time writing for Slate, which is exciting). It’s about the under-appreciated threat to the United States of a disease that we barely think about: the mosquito-borne illness called dengue, formerly known as “breakbone fever.”

Dengue was once endemic in the United States. When I started researching it for this piece, I discovered a whole series of historical outbreaks I knew nothing about: Charleston, SC, 1828; Savannah, Ga., 1850; Austin, 1885; Galveston, 1897; most of Louisiana, 1922; Miami, 1934. Dengue was not eliminated here until the government undertook mass mosquito-eradication programs in the 1940s, because mosquito-borne illnesses were making so many military members so sick that the toll was hampering the war effort. (Public-health history buffs: Those were the campaigns that gave rise to the CDC, which grew out of a government agency called the Office of Malaria Control in War Areas.)

One Family's Journey From Foodborne-Illness Victim to "Food Patriots"

By Leave a Comment

A quick post today, because I have deadlines, and because this Kickstarter closes tomorrow and you should take a look at it while you can.

In February of 2006, when he was 16 years old, Sam Spitz went out for lunch with his high school pals. They were athletes, and looking for a big meal, so they went to a pizza-pasta place. Sam, though, had an inkling of healthy eating from his mother, Jennifer Amdur Spitz, who liked to shop at farmers’ markets. He chose a chicken Caesar salad instead.

By the end of the school day, it seemed like a bad choice. He developed diarrhea so severe that Jennifer and his dad, Jeff Spitz, had to tape an adult diaper on him to get him to the emergency room. The ER staff assumed it was a foodborne illness, took a culture, and sent them home with a broad-spectrum antibiotic.

It had no effect. It took weeks, along with visits to specialists and more tests and more drugs and eventually a colonoscopy, before the family discovered that what had felled the strapping young athlete was an antibiotic-resistant foodborne illness: Campylobacter, a bug that frequently travels on chicken.

Sam Spitz was seriously sick for a month and recovering for many more. He was a pitcher, but missed his entire baseball season, along with the chance to be inspected by college recruiters. He was still on restricted activity when the football recruiters came around the following fall. He eventually recovered (and played football for University of Wisconsin) — but his family’s attitude toward food and food safety was forever changed.

The Spitzes, who are award-winning filmmakers, have documented their journey to a better understanding of our food system in a new film that they are now polishing, called “Food Patriots.” In it, they talk not only about their own dawning understanding of how our food is produced, but also about many other people who are trying to get food grown and distributed in a healthier, more equitable way.

“We were really insulated, as a family, from knowing where our food comes from, and from having the awareness that allows you to make healthy choices,” Jennifer told me. “But this film has a much bigger footprint than just our journey. We’re in it to provide a narrative, and some humor — but what we do is look at people who are inspiring us to think about, buy and eat food differently.”

The Spitzes are in their last 24 hours on their Kickstarter. They have made their initial goal, which was to fund post-production — but in the last day, they’ve been offered a match by a major donor. Anything they receive today will be doubled by the donor, and those funds will be spent getting the film out to communities for screenings.

Jennifer described the film to me as “zero-depth” — like the kind of public pool where you can stand at the end with just your toes wet, and move deeper at your own pace. “There have been a lot of scary, hit-you-over-the-head food films already, and people have already responded to that approach,” she said. “We don’t preach. We want to get people into conversation.”

Take a look.

Footnote: If antibiotic-resistant Campylobacter sounds at all familiar, it may be because I wrote about it in my two-year investigation of foodborne illness for SELF Magazine last summer. Here’s that story and my post about it.

Taliban Murders Six Immunizers in Wake of CIA Polio Ruse

By Leave a Comment

(This post has been updated. Read to the end.)

There is news today, confirmed by several media outlets and also by the World Health Organization and UNICEF, that six people working as polio vaccinators were murdered in three separate coordinated attacks in Pakistan. While no one has yet claimed responsibility, it is widely assumed that the attackers have ties to the Taliban, which has opposed the polio-vaccination campaign as a Western plot and accused vaccinators of working as spies for the CIA.

This is grievous and appalling. Infuriatingly, it was also predictable. Constant readers will remember that, back in 2011, the CIA did use a vaccination campaign as a ruse to attempt to to find Osama bin Laden. The unsuccessful attempt was denounced all over the world for putting the polio campaign at risk, and news sources within Pakistan quickly began reporting that vaccinators were feeling threatened. Adding to the sense of threat, a Taliban commander blocked the campaign in one province last June, a United Nations doctor and his driver were fired on in July, and a vaccinator was executed in October by a man who roared up on a motorbike and dashed away.

The FDA Is Holding Back Data on Farm Antibiotics Use — And Plans to Keep Doing So

By Leave a Comment

Tomorrow morning, the US Food and Drug Administration will consider whether to accept reauthorization of legislation that allows us to know a few details about how many antibiotics are sold each year for agricultural use.

The agency probably will accept the reauthorization, and you would think that would be a good thing. But the untold story of the legislation — known as ADUFA for the Animal Drug User Fee Act — is that the FDA is forgoing opportunities to compel companies to disclose data that it would be in the public’s interest to know.
