Denmark: Three Deaths from Drug-Resistant "Pig MRSA"

A troubling and also kind of odd story came out of Denmark this weekend. In a court proceeding, a microbiologist has disclosed that three residents of the country who had no known connection to farming died of MRSA infections caused by ST398, the livestock-associated strain of drug-resistant staph that first appeared among pig farmers in the Netherlands in 2004 and has since moved through Europe, Canada and the United States.

If the report is correct — and sources have told me it is, but I’ve seen no data to confirm it — it reinforces the concern that bacteria which become resistant because of antibiotic use on farms can move off farms and affect the health of people who have no connection to farming.

Livestock MRSA has always one of the best cases for establishing that, because the drug to which it showed the greatest resistance, tetracycline, wasn’t used against human MRSA in the Netherlands, but was used routinely on farms — so the only place the strain could have picked up its unique resistance pattern was in pigs. (Here’s my long archive of posts on pig MRSA, dating back to my book Superbug where the story was told for the first time.)

News Round-Up: Meat, Superbugs, Denmark And Big Food

July 2, 2012 By Maryn Leave a Comment

I was off-line for a week with family issues, and while I was gone, news broke out. (It senses your absence, news does. This is the real reason why coups and major foodborne outbreaks happen in August.)

So while I dive into the bigger stories that seem to be happening — and get some fun summer stuff lined up — here’s a quick recap of things worth noticing:

Alarm over "pig MRSA" — but not in the US

October 30, 2010 By Maryn Leave a Comment

There’s some new news out — along with a fair amount of public reaction — regarding “pig MRSA” or, to use the technical term, MRSA ST398, the “third epidemic” strain that emerged in pigs in the Netherlands in 2004 and has since appeared, in animals, retail meat, and humans, across the European Union, in Canada, and in the United States. (My last post on it is here, and a long archive of my posts on it starts here.)

I wish I could say the attention to ST398 was being paid in the United States, where there is almost certainly more MRSA in livestock than has been recorded, given that the only published surveillance, from 2009, covered only Iowa and Illinois. Unfortunately, there is still no indication that federal agencies have any intention to test for the presence of the organism in animals or in meat. In fact, the major surveillance mechanism for drug-resistant organisms in meat animals, retail meat and meat-eaters in the US, the National Antimicrobial Resistance Monitoring System or NARMS, doesn’t test for MRSA at all; it handles only enteric or gut-borne bacteria such as Salmonella and Campylobacter. (NARMS IS shared among three agencies: the CDC handles drug-resistant foodborne bacteria in humans, the FDA looks for the same bacteria in food, and the USDA looks for those bacteria being carried by livestock.)

Instead, as so often seems to happen with antibiotic resistance, the country paying attention is in Scandinavia — in this case, Denmark. The annual report from Denmark’s surveillance scheme, DANMAP (Danish Integrated Antimicrobial Resistance Monitoring and Research Programme) is out. Denmark does surveil for MRSA, and here’s what they found: 13% of pigs, at slaughter, were positive for MRSA ST398.

Antibiotic resistance: Scandinavia gets it

September 8, 2010 By Maryn Leave a Comment

Odd but interesting fact: Scandinavia takes antibiotic resistance incredibly seriously. Denmark has one of the most thorough programs for preventing antibiotic misuse in agriculture; Norway has very tough regulations regarding antibiotic stewardship in hospitals (as captured in this AP story last year). Sweden has pressed the issue as well; drug resistance was a major issue for the Swedish Presidency of the European Union in the last half of 2009 and led to a major conference there on creating incentives to bring antibiotic manufacturers back into the market.

The presidency has since been relinquished to more southern countries (Spain in the first half of this year and now Belgium) but the Swedish focus on resistance persists, pushed along by the nonprofit organization ReAct, based at Uppsala University. Earlier this week, ReAct hosted a three-day international conference on antibiotic resistance in Uppsala. They haven’t posted the full conference report yet, but they have come out with a closing press release, which says some interesting things (emphases mine):

At a historic three day conference at Uppsala University, Sweden,
190 delegates representing 45 countries and many leading stake holders – civil society, academia, industry, governments, authorities, supranational organizations – agreed on Wednesday to turn a new page and move towards concerted action on antibiotic resistance…
The new signals from the Uppsala meeting include:
– A shared conviction that antibiotic resistance is a universal problem.
Like global warming, it requires joint action, not least by governmental alliances.
– A clear signal from the pharmaceutical industry that
return of investment on research and development of new antibiotics and diagnostic tools will have to be de-linked from market sales in order to boost necessary innovation while yet limiting the use of antibiotics. This requires a new business model where private and public sectors cooperate.
– A strong recommendation to all stakeholders to
speed up the efforts to limit unnecessary use of antibiotics, while at the same time making the medicines affordable and accessible in developing countries.
– A commitment to
improve the monitoring of antibiotic resistance across the world, through shared data and increased efforts. A global network of surveillance will require common methods, and is crucial for both prudent use and needs driven development of new agents.

The release also mentions some promising events coming next year:

– A final report from TATFAR, The Transatlantic Task Force on Antibiotic Resistance.
– A policy meeting on antibiotic resistance in Delhi, India.
– A WHO Action Plan on Antibiotic Resistance.
– A number of regional initiatives, including in Southeast Asia, Africa and The Middle East.

(Hmm. Surely it is time for me to go back to India…)

People who’ve worked in this field for a long time will know, of course, that up-front commitments are easy to make; it’s downstream action, carried out over the long term, that makes a difference. But this looks like a promising start: Even just stimulating international recognition of the program is an encouraging beginning.

Until the final conference report is posted, you can see video of the opening and final sessions here.

"Pig MRSA" causing human infections

March 4, 2010 By Maryn Leave a Comment

Hi, everyone. Apologies for dropping out of sight! As SUPERBUG’s publication draws closer (and it’s very close now), I keep finding new tasks that I have do to. Last week’s was to go to New York to shoot a video for the Simon & Schuster website — and while there, I got caught in Snowpocalypse, got delayed coming home, and picked up a nasty cold. So I’m a bit behind.

But there’s exciting news tonight to start us up again: “pig MRSA,” ST398, causing human infections in Canada and Denmark.

“Infections” is important, because up til now, most evidence for  the spread of MRSA ST398 in humans has been through detection of colonization, the symptomless carriage of MRSA on the skin and in the nostrils. The first finding of ST398 in the Netherlands was via colonization; so was its first identification in humans in Canada, and also in the United States just about a year ago.
