CDC: Foodborne Illness in the U.S. Not Getting Better

The Centers for Disease Control and Prevention today released their annual survey of foodborne illnesses in the United States, and the news is, well, not great. In the words of the press announcement they sent out to announce the data release: “limited progress.”

The survey — technically the Foodborne Diseases Active Surveillance Network, but usually known as FoodNet — doesn’t cover the entire US; it’s a representative sample drawn from 10 sites in nine states where the CDC already has arrangements with epidemiologists and laboratory personnel. Those 10 sites, most of them at state health departments, cover 48 million people, or about 15 percent of the US population. So among that slice, in 2013, there were:

  • 19,056 lab-confirmed foodborne illnesses,
  • 4,200 of which were severe enough to cause the person to be hospitalized,
  • and 80 of which caused the person’s death.

(For context, the CDC’s extrapolation of foodborne illness nationwide, made in 2011, was 48 million illnesses, 128,000 hospitalizations and 3,000 deaths.)

The agency compared the 2013 numbers against two sets of data, one set taken covering 2010-12 and the other 2006-08. Its summation, from its report in its weekly publication MMWR:

Compared with 2010–2012, the estimated incidence of infection in 2013 was lower for Salmonella, higher for Vibrio, and unchanged overall. Since 2006–2008, the overall incidence has not changed significantly. More needs to be done.

We’re 11 days now into the federal shutdown and four days since the announcement of a major foodborne outbreak in chicken that is challenging the shutdown-limited abilities of the food-safety and disease-detective personnel at the Centers for Disease Control and Prevention, Food and Drug Administration and Department of Agriculture. Here’s an update.

There's a Major Foodborne Illness Outbreak and the Government's Shut Down

Late-breaking news, and I’ll update as I find out more: While the government is shut down, with food-safety personnel and disease detectives sent home and forbidden to work, a major foodborne-illness outbreak has begun. This evening, the Food Safety and Inspection Service of the US Department of Agriculture announced that “an estimated 278 illnesses … reported in 18 states” have been caused by chicken contaminated with Salmonella Heidelberg and possibly produced by the firm Foster Farms.

“FSIS is unable to link the illnesses to a specific product and a specific production period,” the agency said in an emailed alert. “The outbreak is continuing.”

CDC Threat Report: Yes, Agricultural Antibiotics Play a Role in Drug Resistance

By Leave a Comment

The grave assessment on the advance of drug resistance, released Monday by the US Centers for Disease Control and Prevention, contained some important observations about the relationship between antibiotic use in agriculture and resistant infections in humans. Those observations, combined with remarks made yesterday by the director of the CDC and also with testimony given in the past by other CDC personnel, ought to put to rest what seems like a persistent meme: that the CDC has never said, or doesn’t believe, that agricultural antibiotic use plays a role in the advance of resistance.

This is important because it puts the CDC in line with a substantial body of research pointing to agricultural use playing a role in the emergence of resistance outside farm properties. With the CDC agreeing — plus, to some degree, the Food and Drug Administration — surely it’s time to move on to whether there are things that could be done to curb the risks posed by some ag practices, while respecting the role that livestock-raising in particular plays as a substantial economic sector, and as an engine in feeding the world.

News Round-Up: Food, Foodborne Illness, And Antibiotic Resistance In Food

By Leave a Comment

OK, still catching up. Today: food, foodborne illness, and antibiotic use and resistance in food — lots of news in a multi-item rundown. (Under normal circumstances, I’d give each of these items a post of its own; but since they all happened in the past few weeks, it seems better to note them and move on.)

"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.

Becoming Part of the Story (Maybe): The Peanut Butter Recall

By Leave a Comment


Earlier this week, something happened to me that happens to at least 48 million people in the United States every year: I got a foodborne illness. After a completely normal weekend and Monday, I woke in the middle of the night unusually thirsty; I glugged a big glass of water and stumbled back to bed. I got up Tuesday morning still thirsty, feeling kind of chilled and sluggish, and with no appetite. I skipped my usual fruit and yogurt, downed my usual two cups of coffee, skipped my usual hour-long walk and went to my desk.

About two hours later, my abdomen started to cramp.

About 30 minutes after that, I realized it would be a good idea if I went into the bathroom fairly soon.

I was there for a while. [Read more…]

Drug Resistance in Food: Chicken, Shrimp, Even Lettuce (ICAAC 4)

By Leave a Comment

A final post from the ICAAC meeting, which concluded at one end of the Moscone Center in San Francisco Wednesday just as the Apple iPhone 5 launch was beginning at the building’s other end. (Definitely a crossing of geek streams.)

There’s far too much going on at a meeting like this to cover everything. So what emerges, as journalists move around the session rooms and exhibit floors, are stories regarding whatever caught a reporter’s eye based on his or her existing interests and news sense.

What caught my eye was a lot of research into foodborne illness, and particularly into the possibility of food being a reservoir for antibiotic resistance (which, constant readers will know, is something I’m interested in). [Read more…]

Bats, Booze, Bugs, Birds, Blood and Bushmeat (ICEID 4)

By Leave a Comment

Since I started electing to do blog coverage of scientific meetings, I’ve run into an unfortunate reality. On any meeting day, there are one or two presentations that either are strikingly newsworthy or fit into an ongoing topic that I’m already interested in, and that therefore I feel obliged to write about. That means I’m unable to cover dozens, sometimes hundreds, of other interesting papers and posters.

I feel bad about this, especially when authors stop what they are doing to talk to me. So here’s my admittedly insufficient remedy: a quick round-up of a few of the hundreds of intriguing presentations this past week at the biennial International Conference on Emerging Infectious Diseases. (Program here; it’s a pdf, abstracts not individually searchable.) Apologies to everyone whom I didn’t get to.

More News: FDA Curbs One Class of Farm Drugs

By 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:
