Mothers, Farmers and Chefs Against Antibiotic Misuse

May 15, 2012 By Maryn Leave a Comment

If you’ve been reading me for a while, you may remember Everly Macario and her son Simon Sparrow: I told their story in my 2010 book Superbug and blogged about them in 2011. Everly is a public health researcher in Chicago and the sister and daughter of physicians. Yet despite all her own knowledge, and all the knowledge resident in her family, she was unable to protect 17-month-old Simon from the MRSA infection that killed him in 24 hours in 2004.

Simon, as I wrote about him last year, was:

[A] big, sturdy child with no health problems except a touch of asthma. The day before he died, he woke up feverish and disoriented, startling his parents with a cry unlike anything they had heard from him before. It was a busy morning — his older sister had a stomach virus — but they got him to the pediatric ER, got him checked, and brought him home when doctors found nothing unusual going on.

A few hours later, Everly was working at home, watching both kids, and Simon’s breathing changed. Her husband James, a history professor, had driven a few hours away to give a speech. She called a friend who is a pediatrician, held the phone up to Simon’s nose and mouth so she could hear, and then got back on the line.

“Hang up,” her friend said. “Call 911.”

She did, and then she called her husband, who reversed course and began tearing back to the city. At the hospital, Simon failed rapidly: His heart raced, his blood pressure crashed, his lungs filled with fluid. His skin darkened with pinpoint hemorrhages. He died the following morning.

Antibiotics in Ethanol Grains: Glass Half-Empty or Half-Full?

April 10, 2012 By Maryn Leave a Comment

So hi. Apologies to disappear, constant readers — I was mired in the last revise of a big magazine story (which will be out in two months and will be very exciting). Back now, and catching up. Here’s something that caught my eye yesterday, on a topic that I haven’t looked at since this blog was at its former home: the issue of ethanol-manufacturing leftovers, and whether they contribute to antibiotic resistance in the animals they are fed to.

Quick background: Making ethanol is a lot like brewing beer. You take a starchy carbohydrate, wet it down to make a mash, warm it up, add yeast, and wait. To fuel its reproduction, the yeast digests the carbohydrate; as waste products, it respires carbon dioxide and produces alcohol. (So basically beer is yeast pee, but let’s not get off track.)

Does Foodborne Illness Trigger Lifelong Health Problems?

March 30, 2012 By Maryn Leave a Comment

I have a new column up at Scientific American about a health issue that is really just starting to be discussed: Whether foodborne illness causes long-term health problems, and therefore whether it should be a higher medical and public-health priority than it is now.

Quick summary: The few studies that have followed victims of foodborne illness for years afterward show that later in life, they suffer higher-than-usual rates not only of digestive trouble, but of arthritis and kidney problems, as well as greater risk of heart attack and stroke.

More On Court Ordering FDA Hearings on Farm Antibiotics

March 23, 2012 By Maryn Leave a Comment

Since I posted last night on the judge’s order that the Food and Drug Administration examine the safety of farm antibiotics — via hearings that the Food and Drug Administration scheduled, but never held, back in 1977 — a lot has happened. Here’s a round-up.

The Natural Resources Defense Council, lead plaintiffs in the suit (with the Center for Science in the Public Interest, Food Animal Concerns Trust, Public Citizen and Union of Concerned Scientists) has put up a press release/explainer, accompanied by a blog post written by ~~lead~~ attorney Avinash Kar. (Correction: The lead attorney is Jen Sorenson.) Key quote from Kar:

The judge’s opinion makes it clear that FDA’s voluntary approach—letting the industry police itself—does not satisfy its legal obligations. FDA must schedule hearings to let drug manufacturers make their case, and if the drug manufacturers cannot prove that the use of antibiotics in animal feed is safe, FDA must withdraw approval for those drug uses.

Kar’s comment to me: “We think this is a great step forward for public health. For 35 years, FDA has basically sat on the sidelines, mostly letting the industry police itself. In that time we have seen a massive rise in the occurrence of antibiotic-resistant bacteria. This means we now will ensure that we preserve these lifesaving medicines for those who need them most.”

I asked the press office this morning at the Center for Veterinary Medicine, the FDA division named in the order, if the agency has a response yet. They said: “We are studying the opinion and considering appropriate next steps.”

Breaking News: Judge Orders FDA to Examine Safety of Ag Drugs

March 22, 2012 By Maryn Leave a Comment

Here’s breaking news that I’ve learned about. The significance is going to unfold over the next 24 hours and more, and when it does, I will update. (Update: Overnight, a lot came out about this, so I’ve wrapped it all into a new post here.)

Here are the basics:

A district judge in New York has ruled in favor of a coalition that sued the Food and Drug Administration in order to compel the agency to follow through on its 35-year-old attempt to exert control over antibiotics in animal feed known as “growth promoters” — tiny doses of antibiotics delivered in feed and water that are believed to stimulate the evolution of antibiotic-resistant organisms.

Technically, Magistrate Judge Theodore H. Katz has granted the groups’ motion for summary judgement, and denied the FDA’s request that the suit be dismissed.

The decision, filed this afternoon, does not compel the FDA to ban growth-promoter (or “feed efficiency”) use of antibiotics. What it does appear to do, though, is require the FDA to follow through on a process that it began in 1977, when the agency was so concerned over the safety of using penicillin and tetracycline drugs in livestock feed that it called hearings to examine withdrawing its approval of using the drugs in animals.

Because of pressure, largely from certain Congressmen, those hearings were never held.

Gastroenteritis Deaths, Foodborne Outbreaks Increase (ICEID 3)

March 14, 2012 By Maryn Leave a Comment

Several related pieces of news today from the International Conference on Emerging Infectious Diseases:

The number of people who are dying from illnesses that involve vomiting and diarrhea more than doubled between 1999 and 2007, and most of the increase was due to Clostridium difficile.
Disease outbreaks caused by imported foods are rising, and tainted foods are coming into the United States from a wider array of countries than before.

Staph In Pigs And Pig Farmers: The Latest Reports (ICEID 1)

I’m spending the first part of this week at the International Conference for Emerging Infectious Diseases, a biennial scary-disease nerdgasm that is sponsored by the Centers for Disease Control and Prevention, the American Society for Microbiology and other worthy organizations, and in this iteration has drawn about 1,600 participants from more than 50 countries. (You can see the program here. I had planned to live-blog it, but the hotel was just renovated and apparently they built a Faraday cage into it, since connectivity is a painful trickle.)

On Monday’s agenda, among other intriguing talks: Two updates on MRSA, methicillin-resistant S. aureus, among farmers in two states.

High Levels of Resistant Bacteria on Meat (Again)

March 3, 2012 By Maryn Leave a Comment

A new report is out from the federal collaboration that monitors antibiotic resistance in animals, retail meat and people, and the news is not good.

The full title is the 2010 Retail Meat Report from the National Antimicrobial Resistance Monitoring System. This report is issued by the Food and Drug Administration; the humans one comes from the Centers for Disease Control and Prevention and the animals one from the US Department of Agriculture. It reports the results of testing on 5,280 meat samples collected in 2010 in California, Colorado, Connecticut, Georgia, Maryland, Minnesota, New Mexico, New York, Oregon, Tennessee, and Pennsylvania. (Those are sites of state labs participating in a federal surveillance network, FoodNet, plus one volunteer lab, Maryland.)

The report — which is broken down first by foodborne organism and then by meat type — notes a number of instances where either the percentage of bacteria that are antibiotic resistant, or the complexity of the resistance, is rising. Quoting from the report:

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:

'Pig MRSA' Came From Humans, Evolved Via Farm Drugs

February 23, 2012 By Maryn Leave a Comment

In the summer of 2004, a 6-month-old girl who lived in the southeastern part of the Netherlands — prime, intensive hog-farming country — went in for surgery for a birth defect of her heart. As is routine in the Netherlands, which has excellent hospital infection control, she was checked before surgery for MRSA, the drug-resistant bacterium that can live on the skin without causing infections and can be unwittingly transmitted from one patient to another. The girl was carrying MRSA, which was a surprise — but the bigger surprise was that her MRSA strain did not render any results on the standard identification test, PFGE.

Looking for a source for the mysterious strain, the hospital epidemiologists where the girl was being treated asked to check her family: father, mother, school-age sibling. They were carrying it. They asked to check the family’s social circle; some of them were carrying it too. Then, flailing about for an answer — the Netherlands has such low rates of MRSA that these persistent findings were really rather odd — the epidemiologists asked what the family and their friends all did for a living, and received the answer that they were all pig farmers. So they checked the pigs, and the pigs were carrying the MRSA strain as well. And if a new MRSA strain in humans was odd, then a MRSA strain in pigs was very odd — because swine have their own varieties of staph, and are not supposed to get S. aureus, the usually human strain that accounts for the “SA” in MRSA.

That summer of detective work (which is told in full in my book Superbug) provided the first sighting of what would come to be called MRSA ST398, or in Europe CC398: a strain which was not quite like hospital MRSA, and not quite like community MRSA, and which carried a distinctive signature of resistance to tetracycline, a drug that is not much used for human MRSA but is routinely used in confinement-style farming. From its first identification, ST398 spread rapidly through Europe, and then into Canada, and then to the United States, being found first in pigs and pig-farm workers, and then in retail meat, and then in people with no connection to farming at all.

The only mystery was where it had come from.

Moving Beyond Factory Farms: Pastured Poultry

February 10, 2012 By Maryn Leave a Comment

It’s astonishing what you can not know about the place where you live. Me, for instance: I live mostly in Atlanta. I’ve lived here twice, once for 10 years as a newspaper reporter, and now — after a four-year break — for 15 months so far as a writer (and trailing spouse, which is how I got back here). Between working for one of the (formerly) largest papers in the country, liking long drives, and regularly indulging my ungovernable curiosity, I thought I knew Georgia pretty well.

I was wrong. Here’s what I learned about Georgia on Thursday:

It raises more meat chickens than any other place in the United States, about 1.4 billion of them a year.
That’s 15 percent of all the animals raised in confinement agriculture in the United States. Not just 15 percent of the chickens; 15 percent of everything.
All those chickens produce 2 million tons of poultry manure and litter a year, one-fifth of what the entire U.S. poultry sector produces.
That waste is applied on land — including land where other food crops are grown — from which it can run off and contaminate water supplies.
40 to 80 percent of gut bacteria recovered from confinement chicken-houses are multi-drug resistant.
Caring for foodborne illness from organisms carried on chicken, and making up for lost productivity when people are made sick, costs about $2.4 billion per year.
Chicken catchers, who cage the birds on their way to slaughter, may lift 5,000 pounds in an hour. Slaughterhouse line workers may perform the same repetitive cutting motions 20,000 to 30,000 times in a work shift.
Slaughterhouses in Georgia kill 1 million chickens per week.
Poultry is exempt from humane slaughter regulations.

Drug Resistance in Pork: More Going On Than Appears

January 31, 2012 By Maryn Leave a Comment

A paper released recently, by the University of Iowa team that is the lone US research group tracking “pig MRSA” ST398, caused a ripple. (It came out while I was at ScienceOnline and it’s taken me a while to catch up.) The paper compares the occurrence of MRSA, drug-resistant staph, on various cuts of retail pork from pigs that were raised either conventionally in confinement, with routine use of antibiotics, or in an alternative rearing scheme with no antibiotics. (NB: Not “organic,” despite what some headlines said; that’s a separate issue of USDA licensure.) The team found that both conventionally raised and antibiotic-free meat carried MRSA, both the human-associated kind and the pig-adapted kind.

The TL;DR over the past week has been: There’s just as much resistant bacteria on drug-free meat as there is on conventional meat, so why spend the money — or raise the alarm over farm antibiotic use?

My interpretation is a little more nuanced. But my takeaway is that, in its underlying data, the study proves what campaigners against ag antibiotic use keep saying: that once you use antibiotics indiscriminately and drive the emergence of resistant organisms, you have no way of predicting where that resistance DNA will end up.

Why Is Type 1 Diabetes Rising Worldwide?

January 26, 2012 By Maryn Leave a Comment

We’ve gotten sadly accustomed by now to warnings about obesity and its effect on health: joint damage, heart disease, stroke, diabetes and its complications such as blindness and amputation. We almost take for granted that as obesity increases worldwide, diabetes will also, and it is. That is, type 2 diabetes — the kind that is linked to obesity and used to be called adult-onset diabetes — is rising as obesity does.

But here’s a puzzle: Type 1 diabetes — the autoimmune disease that begins in childhood and used to be called juvenile-onset diabetes — is rising too, around the globe, at 3 percent to 5 percent per year. And at this point, no one can quite say why.

More News: FDA Curbs One Class of Farm Drugs

January 4, 2012 By Maryn Leave a Comment

Here’s a bookend to the Food and Drug Administration’s disappointing Christmas Eve notice that it will cease trying to regulate the largest classes of growth-promoter antibiotics. Today, the agency announced that it is forbidding certain uses of a different class of drugs, cephalosporins.

To those who are concerned about antibiotic overuse in agriculture, though, this is good news — though it may be more good news-bad news-bad news-good news.

The dialectic looks like this:

FDA Documents Show Agency Once Strongly Opposed Farm Antibiotic Overuse

December 29, 2011 By Maryn Leave a Comment

The use of antibiotics and sulfonamide drugs, especially in growth promotant and subtherapeutic amounts, favors the selection and development of single and multiple antibiotic-resistant and R-plasmid-bearing bacteria.

Animals that have received either subtherapeutic and/or therapeutic amounts of antibiotic and sulfonamide drugs in feeds may serve as a reservoir of antibiotic resistant pathogens and non-pathogens. These reservoirs of pathogens can produce human infections.

The prevalence of multi-resistant R-plasmid-bearing pathogenic and nonpathogenic bacteria in animals has increased and has been related to the use of antibiotics and sulfonamide drugs.

Organisms resistant to antibacterial agents have been found on meat and meat products.

If you give the text above a close read, you might think it was written by Mark Bittman or Tom Philpott or Tom Laskawy, or me — or any of the small number of journalists who focus on the safety and policy perils of giving scarce antibiotics to confinement-raised farm animals. After all, what it says is what any of us would say: Routine administration of antibiotics to livestock spurs the emergence of drug-resistant bacteria that move through the food chain, threaten human health, and lend their DNA to yet other bacteria, increasing the reservoir of resistance in a dangerous and untracked manner.

As it happens, though, the text above wasn’t written by any of us. It was written by the Food and Drug Administration, the FDA.

Yes, the FDA — the federal agency that, as I wrote last Friday, has just backed off a 34-year attempt to assert regulatory control over “growth promoter” antibiotic use, opting instead for voluntary self-policing by the agricultural and pharmaceutical industries.

News: FDA Won't Act Against Ag Antibiotic Use

December 23, 2011 By Maryn Leave a Comment

With no notice other than a holiday-eve posting in the Federal Register, the US Food and Drug Administration has reneged on its long-stated intention to compel large-scale agriculture to curb over-use of agricultural antibiotics, which it had planned to do by reversing its approval for putting penicillin and tetracyclines in feed.

How long-stated? The FDA first announced its intention to withdraw those approvals in 1977.

From the official posting:

The Food and Drug Administration (FDA or the Agency) is withdrawing two 1977 notices of opportunity for a hearing (NOOH), which proposed to withdraw certain approved uses of penicillin and tetracyclines intended for use in feeds for food-producing animals based in part on microbial food safety concerns.¹ … (¹FDA’s approval to withdraw the approved uses of the drugs was based on three statutory grounds: (1) The drugs are not shown to be safe (21 U.S.C. 360b(e)(1)(B)); (2) lack of substantial evidence of effectiveness (21 U.S.C. 360b(e)(1)(C)); and (3) failure to submit required reports (21 U.S.C. 360b(e)(2)(A)).)

There is a lot of background to this, but here is the takeaway: For 34 years, the FDA has been contending that administering small doses of antibiotics to healthy animals is an inappropriate use of increasingly scarce drugs — a position in which it is supported by organizations as mainstream as the American Medical Association. With this withdrawal, it backs away from the actions it took to support that assertion — which may indicate there will be no further government action on the issue until after the 2012 election.

Antibiotics: Connected to Obesity, Diabetes and Stroke?

November 25, 2011 By Maryn Leave a Comment

In consideration of your glaze-eyed tryptophan coma — at least among those who weren’t frightened off by the MRSA-in-turkey news — today’s post is mostly composed of brightly colored pictures. (Also, speculation. You’ve been warned.)

About a week ago, a nonprofit research group called Extending the Cure published the latest in a fantastic series of maps they have been producing for several years, based on public and privately collected data. Earlier iterations have looked at the incidence of various resistant organisms over time. This time, they decided to look instead at the major drivers of resistance, and focused on national data about antibiotic prescriptions, broken down by drug type and by state between 1999 and 2007.

The graphics they produced document both a troubling growth in the use of some precious (because still effective) antibiotic classes, and also a surprising differential in the amounts of antibiotics prescribed in different parts of the country. The rate of use of antibiotics, measured by outpatient prescriptions per 1,000 inhabitants, varied from a low of 533 in Alaska to a high of 1,214 in West Virginia. [Read more…]

More MRSA Found In U.S. Retail Meat (Turkey, Too)

November 22, 2011 By Maryn Leave a Comment

There are two new studies out that confirm, once again, that drug-resistant staph or MRSA — normally thought of as a problem in hospitals and out in everyday life, in schoolkids, sports teams, jails and gyms — is showing up in animals and in the meat those animals become.

The strain of staph that shows up in farm animals, known as “livestock-associated” MRSA or MRSA ST398, first emerged in pigs in the Netherlands, and has been widely identified in retail meat in Europe. (You can find a long archive of posts on ST398 here, and more here.) But that same strain has been difficult to identify in the United States. That may be due in part to the U.S. having a uniquely massive epidemic of community-associated MRSA, far larger than in any other country, which likely both obscures any animal epidemic from detection, and possibly also fills the ecological niche that livestock-associated staph might otherwise occupy. But, it must be said, there’s also remarkably little political will to look for livestock-associated MRSA (though the U.S. Department of Agriculture has now funded a study).

Nevertheless, individual investigators keep trying, and when they look for the pathogen, they find it, such as in these studies from May and this one from April. Now, two other teams have as well.

EU Parliament Votes To Oppose Most Farm Antibiotic Use

November 7, 2011 By Maryn Leave a Comment

A quick post, because I’m on a ferocious deadline, but still can’t let this news go by. In a vote that’s non-binding but high profile and influential, the European Parliament has resolved to end “prophylactic use” of antibiotics in farming, and to prevent any “last resort” antibiotics from being used in animals, in order to keep resistance from developing so that the drugs will still be effective in human medicine.

This is a significant development. The European Union has already banned “growth promotion,” the use of micro-doses of antibiotics that cause meat animals to fatten more quickly. What the Parliament is doing here is asking the European Commission, the EU’s law-making body, to add “disease prevention” use to the ban. That’s the delivery of treatment-strength doses of antibiotics to all animals on a farm in order to prevent their becoming ill as a result of the confinement conditions in which they are held. It accounts for a substantial portion of the antibiotics used in agriculture, and is a major driver of the emergence of antibiotic-resistant organisms.

Government Health Agency Agrees Mega-Farms Are A Health Risk (In The UK)

November 4, 2011 By Maryn Leave a Comment

It’s very odd sometimes watching how the same issues play out in different parts of the world. The French environment ministry confidently ascribes the growth of seaweed choking its beaches to farm runoff. The European Parliament denounces the establishment of very large-scale “meat factories.” China (China!) enacts a ban on growth-promoting uses of antibiotics in agriculture.

Here in the United States, on the other hand, the government gropes unsuccessfully for a way to put controls on confinement agriculture, despite evidence of its environmental harm, while at the same time those farms grow by an estimated 4,600 hogs and 5,800 broiler chickens per day.

For more of that difference between Europe and the US, look this week to England, where the Health Protection Agency has just rejected the zoning application for a hog farm that was small by US standards, with a plan for only 2,500 sows producing about 20,000 piglets. The HPA said:

… those living up to 150 meters downwind of an intensive swine farming installation could be at risk of adverse human health effects associated with exposure to multi-drug resistant organisms. (this .pdf, p.30 of 44)
