From Bird Flu to Big Farms: The Rise of China's Agriculture

February 21, 2014 By Maryn Leave a Comment

In my last post, I talked about the unnerving increase in avian flu H7N9 in China. The novel flu strain, now in its second year, appears to be spreading more rapidly than it did in its first appearance, and also more rapidly than H5N1, the avian flu strain that has caused the most worry internationally.

You can’t have avian flu — or at least, not this avian flu — without birds; most of the people who have been diagnosed with H7N9 had contact with live chickens or visited a market that sold live poultry for slaughter. H7N9 is continuing to spread in China; and so it’s a lucky coincidence that a nonprofit with deep knowledge of Chinese agriculture has just published a series of reports exploring the vast expansion of Chinese production of meat animals, including chickens.

Cast your mind back to about this time a year ago. A novel strain of flu, influenza A (H7N9), had emerged in China, in the provinces around Shanghai. International health authorities were deeply concerned, because any new strain of flu bears careful watching — and also because, on the 10th anniversary of the SARS epidemic, no one knew how candid China would be about its cases.

By the time peak season for flu ended in China, there had been 132 cases and 37 deaths from that newest flu strain. But, confounding expectations, the Chinese government was notably open about the new disease’s occurrence, and scientists worldwide were able to ramp up to study it. Still, no one could say whether that flu would be the one to make the always-feared leap to a pandemic strain that might sweep the globe. As with other, earlier, worrisome strains of flu, science could only wait and see whether it might return.

And now it has.

USDA: Chicken Processed in China Can be Sold in the US Without Labels to Say So

September 4, 2013 By Maryn Leave a Comment

source: nugget photo and poor Photoshop skills by me.

Catching up to this news, which dropped quietly just before the holiday weekend: In a first, the US Department of Agriculture has given permission for chicken products processed in the People’s Republic of China to be sold in the United States without labeling that would indicate where the chicken products came from.

The news was broken by Politico, whose writers obtained USDA documents before the agency released them, and then followed up by the New York Times, with some no-holds-barred analysis by Bloomberg Businessweek.

If you’ve been reading for a while, you’ll know that food safety in China is well below US standards. (See this post for stories of toxic vinegar, glow-in-the-dark pork, and more.) So it may be a surprise to hear that birds grown and slaughtered outside that country, but cooked and made into products in it, would be acceptable for sale here. Especially since the plants that USDA has approved for sales into the US market will not have USDA inspectors on site.

Here is the USDA notice, in the form of an audit issued by the Food Safety and Inspection Service.

The "Road Not (Yet) Taken" On H7N9 Flu — And How Far We've Gotten

June 10, 2013 By Maryn Leave a Comment

Last week’s New England Journal of Medicine included a thoughtful meditation on the possibility that the new bird flu out of China, H7N9, could become a globe-spanning pandemic — and on how much knowledge is needed before we’ll be able to predict whether it will or not. The authors, all from the US National Institutes of Health, know a fair amount about pandemics: Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases; Dr. David Morens, Fauci’s senior advisor and a medical historian; and Dr. Jeffery Taubenberger, a physician and microbiologist who brought back to the world the viral cause of the worst pandemic: the influenza of 1918, which killed 100 million people.

In various combinations over the past 10 or so years, the three have written a number of papers looking back at the record fro 1918, interrogating its impact, and particularly examining the causes of its extraordinary death toll. So they are probably the perfect authors to write about gaps in knowledge about H7N9.

But aside from its useful examination of the virology, what struck me as most interesting about their paper is how soon it is to be able to write something like this. After all, H7N9 only emerged to public knowledge in late February, and so far has caused 132 cases and 37 deaths, all in eastern China. That these authors could write this paper now is yet another marker, I think, of how different this outbreak is from SARS 10 years ago, as well as how rapidly international public health science can move, if everyone cooperates.

World Health Organization Annual Meeting: New Flu, Coronavirus Urgent Priorities

May 20, 2013 By Maryn Leave a Comment

In Geneva today, the World Health Assembly — that is, the annual meeting of the 194 governments whose collective commitment support the World Health Organization — opened as traditional, with a speech by the WHO’s director-general, Dr. Margaret Chan. It is a very interesting time, not just for the WHA to be meeting, but for Dr. Chan to be addressing them. That’s because, 10 years ago when SARS exploded into the world from China, she was the director of health for Hong Kong, the city that was hit first and hardest. Ten years later, with H7N9 flu emerging from China, and a viral relative of SARS — the novel coronavirus now being dubbed MERS — bubbling in the Middle East, the questions and lessons of SARS are bizarrely resonant. That has been true for the past several weeks, but is even more so today, with one more case of MERS announced, in one more country: Tunisia, this time.

Here are the opening paragraphs from Chan’s speech (full text online here). To me it’s quite interesting how much she praises China for its transparency in dealing with H7N9 flu — while not extending the same praise to the Kingdom of Saudi Arabia, where MERS is concentrated. In fact, she doesn’t even mention Saudi Arabia by name; whether that is meant to give offense, or to avoid it, other public-health tea-leaf readers can say better than me. Though her closing comment — “the current situation demands collaboration and cooperation from the entire world” — sounds pretty pointed to me.

Transparency Unlocked: More New Saudi Coronavirus Cases Reported Quickly

May 4, 2013 By Maryn Leave a Comment

In my last post 36 hours ago, I raised questions about Saudi Arabia’s apparent delay in reporting new cases of the novel coronavirus that has been causing low-level unease since last summer. (For the full history of that, check these posts.) So it’s only fair to say that, within 24 hours, the Saudi government behaved very differently with a new report.

The bad news is, the new report is about yet more cases of the novel virus. But the good news is, the report of the new cases was quickly shared internationally, by the government’s Deputy Minister for Public Health, via the international disease-alert mailing news ProMED.

New Diseases and National Transparency: Who Is Measuring Up?

May 2, 2013 By Maryn Leave a Comment

I’m still catching up on all the news that happened during the weeks I was away, and I had a food-policy post just about set to go today. And then this happened.

I opened my morning mail to find a note from a private list I subscribe to, published by a company that monitors hazards for businesses with expatriate employees. The note flagged new news from Saudi Arabia:

Saudi Arabia: Seven more case of novel coronavirus reported
Seven people in Al-Ahsa governate in the Eastern province have been confirmed infected with the novel coronavirus. Five have died and the other two are critically ill in intensive care. It is unclear whether there are any links between these cases or whether they are “sporadic” infections. Overall the risk to travellers remains low.

This was odd. You’ll remember the new coronavirus, distantly related to SARS, which surfaced last year in a slow and not well-disclosed manner (for the back story, see these posts from last September, October, November and December). Since the initial reveal last year, there has been very little information released about the virus and whatever illness it might be causing. The World Health Organization has been monitoring the gradual accumulation of cases, but there has been almost nothing published since last fall. In fact, though teams from Columbia University and the Centers for Disease Control and Prevention have been to the Kingdom of Saudi Arabia to help investigate the new illness, neither entity has published anything since those trips were made. And at the point at which I opened my inbox this morning, the WHO’s last update on the new virus had been published on March 26.*

Meanwhile, of course, the infectious disease world has been riveted by the rapid emergence in China of a different virus, the new avian flu H7N9, and many questions have been aimed at whether the Chinese government, which attempted to conceal the emergence of SARS 10 years ago, has learned the lesson of transparency. (I talked about that history, and how the world found out about SARS, in this segment from On the Media a few weeks ago.)

Almost since H7N9 emerged in March, though, the WHO and other bodies have been averring that China is actually doing a good job this time around. And with this overnight news from Saudi, it seems that the questions about disease-outbreak transparency may have been directed at the wrong country.

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

February 12, 2013 By Maryn 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.”

Also Receiving Antibiotics on Factory Farms: Shrimp

February 24, 2012 By Maryn Leave a Comment

Tom Philpott of Mother Jones had a great post earlier this week looking at the vast environmental damage caused by shrimp farming in South and Southeast Asia. He takes off from a presentation at the annual meeting of the American Association for the Advancement of Science by J. Boone Kauffman of Oregon State University, which examined the destruction of coastal mangrove forests that allows shrimp farms to be established and found that shrimp’s carbon footprint is 10 times higher than that of beef cattle. Tom says:
