In the search for the swine flu outbreak’s “ground zero,” blogs have called upon mainstream media to investigate the potential role of large factory farms in breeding and spreading the virus.
Major news outlets have tentatively begun to do just that over the last two days. Reports have focused on the town of La Gloria, Mexico, where the first known victim was identified. (He has since recovered.) La Gloria is located close to a million-pig farm, Granjas Carroll, which is partly owned by Smithfield Foods, an American company that is the world’s largest producer and processor of pork products.
So far, however, there is no evidence of a direct connection between the farm and the swine flu virus. But there are reasons to both suspect and doubt that such a connection exists, and this has led to sporadic arguments among reporters covering the outbreak about the line between asking tough questions and jumping to conclusions.
The first blogger to implicate industrial hog farms was Grist’s food editor, Tom Philpott, in a Saturday post headlined, “Swine-flu outbreak could be linked to Smithfield factory farms.” Philpott cited a swine-flu timeline posted by the blog Biosurveillance, as well as articles in the Mexican newspapers La Marcha and La Jornada, which had reported that residents of La Gloria suspected the Granjas Carroll farm of spreading sickness via “clouds of flies” that travelled between the two. Philpott’s assessment was that:
[T]he possible link to Smithfield has not been reported in the U.S. press. Searches of Google News and the websites of the New York Times, Washington Post, and Wall Street Journal all came up empty. … I’ll be in touch with contacts in Mexico as this story develops —and I’ll be curious to see whether the U.S. media explores the link with Smithfield’s Mexico operation.
At The Huffington Post on Sunday, freelance reporter David Kirby commented on the recent spread of industrial-scale hog farms, or confined animal feeding operations (CAFOs), in Mexico, suggesting that:
U.S. and Mexican epidemiologists and veterinarians will surely want to take swine samples from Mexican CAFOs and examine them for the newly discovered influenza strain (No one knows exactly how long it has been in circulation). And though it is too early to know if this new virus mutated and incubated on Mexican hog CAFOs, the industrialized facilities unquestionably belong on the list of suspects.
“This should be one of the big second-day stories of this remarkable news event,” argued Tom Yulsman at the Center for Environmental Journalism on Tuesday, in a blog post headlined, “What mainstream media aren’t telling you about the swine flu outbreak.” Yulsman pointed to a recent report from the Pew Charitable Trusts and Johns Hopkins Bloomberg School of Public Health, which found that “Animals in such close confinement, along with some of the feed and animal management methods employed in the system, increase pathogen risks and magnify opportunities for transmission from animals to humans.”
Mainstream media granted Philpott and Yulsman’s wish for more coverage almost as soon as they’d made it. Major outlets have been far more skeptical and restrained in their reporting about the CAFO hypothesis, however. The reason is that, so far, authorities have yet to find an infected pig in Mexico, let alone at the Granjas Carroll farm. None of the pig farm’s workers appears to be sick, either.
The result is that most mainstream news articles—such as those in The New York Times, The Washington Post, and The Wall Street Journal—have included only a paragraph or two about Granjas Carroll in larger stories about La Gloria being a prime candidate for the flu outbreak’s origin. The Associated Press and CNN’s Sanjay Gupta visited Granjas Carroll, but only the former got in.
These reports could do little more than state the facts, however. For now, the only people who are “convinced” that the CAFO is at fault are the residents of La Gloria. Most articles printed the canned statement from Smithfield and the Mexican government, saying that they have “found no clinical signs or symptoms of the presence of swine influenza in its herd or its employees working at its joint ventures anywhere in Mexico.” That statement, of course, belies the fact that it is unclear whether or not anybody has actually tested the pigs and workers at Granjas Carroll. At CNN, Gupta reported that Smithfield and the Mexican Department of Agriculture told him they had, in fact, done testing, which had come back negative. Even if they have tested, however, it is clear that independent verification is needed. The United Nations’ Food and Agriculture Organization has sent an emergency response team to the area, but there is still no word about what it has found.
There have been a few exceptions to the restrained coverage in mainstream news outlets (mostly among British publications, curiously enough). The Times of London and The Independent ran articles that themselves were not substantially different from others. Their respective headlines, however—“Mexico outbreak traced to ‘manure lagoons’ at pig farm” and “For La Gloria, the stench of blame is from pig factories”—were sensationalistic and grossly misleading.
The Guardian has run two op-eds on the subject. One, by a University of California history professor, made the rash statement in its lede that, “The Mexican swine flu, a genetic chimera probably conceived in the faecal mire of an industrial pigsty, suddenly threatens to give the whole world a fever.” The other, by a member of the European Parliament, called for more research and quoted the director of Public Health and Animal Agriculture at the U.S. Humane Society saying that the first triple-hybrid swine flu virus (as the one responsible for the current outbreak appears to be) emerged at a North Carolina factory farm in 1998.

The one point you totally skipped in this piece was to state clearly that swine flu can not be transmitted by eating properly cooked pork. It's even on the CDC's fact sheet:

Jake, that is a very good point. To be clear, the worry isn't so much that people in La Gloria or elsewhere would have contracted swine flu from eating pork products from Granjas Carroll. Rather, it is that the disease might have been transmitted by some other vector, such as flies or direct contact with the pigs themselves. But this brings up another very good point about why one should not rush to conclusions about this CAFO. We still don't have any evidence that the flu even started in Mexico, let alone Granjas Carroll. Merritt Clifton, the editor of Animal People news and certainly no friend of factory farming, just posted an excellent argument at Grist for not jumping the smoking gun on this one. There are still competing explanations out there, Clifton writes, including a report of a migrant worker possibly bringing the flu to La Gloria from the U.S. Given viruses' ability to move quickly and globally, hard evidence is key.

Interesting article. Where I'm from people are freaking out about it too, so I created an ebook to help people out. You can download it a www.jamesryanhamilton.com/swineflu

Sometimes if it looks like a duck and walks like a duck, it's a duck. The locus of outbreak and strain for flu both implicate the local CAFO. Common sense and a modicum of deductive reasoning will tell you that animals kept in dirty, crowded conditions under stress will be more susceptible to disease. The only defense of the mega-CAFO is economics. From the standpoint of ethics (treating animals horribly, way worse than kicking a dog) and science (low quality meat, tainted groundwater), they are utterly indefensible.
The swine flu is a crock anyway. More people died from heart attacks in the USA in the past hour than have died globally in the past week from this thing.

Hey all, found this site, it has updates and general info on the swine flu outbreak sorted by country (ie US, Mexico, New Zealand, Europe) seems quite good...

This is a terrific review of how bloggers, including myself, have handled the flu outbreak. I accept both the praise and the criticism, which I think is fair.
For the record, though, let me make it clear that I never made the point that a particular CAFO in Mexico was a likely source of this flu outbreak. Here's what I wrote:
"...it is possible that the virus that has killed 149 people in Mexico jumped from a hog in an industrial operation to a human being. I emphasize the word “may” because no one knows yet whether this is the case, and it may never be known. Even so, credible researchers have raised the alarm, so this story deserves at least some attention."
I called on journalists to shift from reporting on the latest new cluster of cases and start reporting on the broader scientific, historical and social contexts. The broader scientific context is that flu viruses mutate rapidly, which allows them to jump from species to species. And this is made easier when a large number of animals, such as pigs in the extremely tight confines of a CAFO, are in close proximity to people.
As Brainard's excellent review states, it is time for responsible investigation of this angle on the flu outbreak story.

Excellent article. I hope it will be widely read.

This is a very fine review of events, and much appreciated. I also have a couple of comments.
I have been interviewed by mainstream media about this story, and often I am the one who must remind them that there is no proof that this virus originated in Mexico, including an appearance this week on CNBC’s “Power Lunch” www.tinyurl.com/kirbycnbc.
In all of my Huffington Post pieces, I have made it clear that we do not know where this virus originated, as you indicated. Even in my current piece online, I state that it is “entirely possible” the virus did not come from a Mexican CAFO, but it is not a “wild theory” either, as Reuters labeled it in a story yesterday.
That said, I still think there is plenty of evidence to continue investigating Mexico and swine CAFOs (on all continents) because this virus had to have mutated somewhere into its current form – and residents of La Gloria began complaining of strange flu symptoms in February, if not sooner. Only one four-year-old boy’s sample was tested, and it came back positive for the new H1N1 strain. It could be a coincidence that he was the only person in town to get the disease, and stranger things have happened, but it remains suspect.
Meanwhile, testing of pigs may reveal nothing, because the virus may have moved out of the herd by now, or carrier pigs may have died or been killed. I believe that workers should also be tested for low-level, asymptomatic infections, which is more likely to occur among people who are exposed to Zoonotic pathogens on a daily basis and develop some immunity, animal scientists told me.
Which leads me to my final point. You note that bloggers, “did not call experts to test their theories.” I can’t speak for others, but I spent hours interviewing officials from the CDC, USDA and the US Trade Office, as well as Dr. Ellen Silbergeld, professor of environmental health sciences at Johns Hopkins Bloomberg School of Public Health, and a leading researcher of pathogen evolution in CAFOs; Dr. Liz Wagstrom, director of veterinary science at the National Pork Board, Dr. Gregory Gray, a University of Iowa professor of international epidemiology and expert in zoonotic infections, Bob Martin, former executive director of the Pew Commission on Industrial Farm Animal Practices and currently a Senior Officer at the Pew Environmental Group; plus some US hog growers and other people involved in agricultural science.
All of them said the La Gloria connection was a plausible explanation, and some thought it was likely. Thanks again for a nice roundup of events.

Tom & David, thanks for the comments. You both make valid points. I should have included another paragraph about your posts as wells as Tom Philpott’s. Indeed, it is important to emphasize that you were all raising the question, not making an accusation, and that nobody was flying off the cuff in doing so.
