Radiation exposure in Russia blamed on Fukushima crabs

I’m a sucker for food safety jokes, and the punchline of “it must have been the Fukushima crabs” is a beauty.

According to the Telegraph, doctors in Russia who treated victims of a military test explosion have evidence of being exposed to radioactive materials, with isotopes being found within their muscle tissue.

Officials however are playing the food safety card when trying to explain why cesium-137 is there.

Staff from the Arkhangelsk regional hospital were not informed at first that they were treating irradiated patients, and protective measures were not taken until the next day, they told Russian media this week.

In some cases, staff said they were falsely told patients had been decontaminated.

One doctor was later found to have the isotope Caesium-137 in his muscle tissue. He was told he must have eaten too many “Fukushima crabs” during a trip to Thailand, his colleague told the news outlet Meduza.

In related news, Chernobyl on HBO is excellent.

 

Lost luggage with roasted green chiles leads to a food safety issue

Don and I were part of the latest episode of Underunderstood where we chat about the food safety risks associated with roasted green chiles (that started out frozen, and ended up ‘cool to the touch’) being in lost luggage for a couple of days.

Check out the episode for more details.

Food Safety Talk 187: Must Split and Toast

Don and Ben do their annual live from IAFP show. This year, from the dungeons of the Kentucky International Convention Center, the guys are joined by listeners coming from as far at New Zealand. The show starts with a discussion of IAFP meeting happenings, symposia and back room chatter. The discussion goes to some listener feedback on Chipotle, English muffins, donut walls and ignoring voluntary recall guidance. And papayas.

Petting zoo illnesses make me sad because the food and ag community has failed

I’m a fan of agritourism, whether that’s touring a bunch of backyard chicken coops or learning about animals, I see value in this stuff. It’s not without risk though – and managing that risk is imperative. A while ago someone asked me about the types of food businesses I like to frequent, from a food safety perspective, and I thought about it a while and came up with this: I like to eat food from places where the people involved in making decisions are constantly worried about making people sick. Like it’s their nightmare. Not places that tell me not to worry about stuff.

My petting zoos/animal interaction wants are the same.

A few years ago my friend (and Carolina Hurricane superfan), Dr. Megan Jacob and I took a couple of visits to animal education/interaction sites to get some ideas about what people do (visitors and organizers). From those visits we saw a lot of stuff that made us think we need to take a different approach. Lots of signs saying to wash hands. Don’t bring food around the animals, don’t bring strollers.

And not a lot of people following the messages. I don’t blame the visitors. I blame us (or at least the collective us) for not doing a better job at saying why it’s important, not having enough people there with reminders and actively helping visitors reduce their risks.

A couple of years ago Gonzalo Erdozian esteemed member of the barfblog team, looked at what was available at a bunch of small petting zoo sites/events in Kansas and Missouri – and came up with some great suggestions after finding lots of risky practices (abstract is below). Reducing risks at fairs and petting zoos isn’t a simple thing – it’s a mix of having the tools, people to point patrons to them, and explaining the risks (without being jerks).

Gonzo found that the reminders really worked.

After those visits, Megan and I, with the help from some others put together a workshop for NC folks who run these events and sites. We learned a whole bunch more from the participants – one of the biggest takeaways for me was that organizers were reluctant to engage in these discussions because although they knew that there was a risk, they didn’t want to alert people who were there that it was risky because maybe they wouldn’t come. I’m not sure what the correct word for that is, but it seems paternalistic or something. One philosophy we’ve followed at barfblog is that people can handle risk discussions and we’re kinda responsible to have them. And let the participants choose.

I home almost daily past the Kelley Building, ground zero for an E. coli O157:H7 outbreak in 2011 linked to 25 illnesses at  the NC State Fair. The building wasn’t considered to be an animal contact area – a petting zoo – but was a spot that was a popular cut-through from an entrance gate to the midway area. Organizers of the fair led a commission to look at what happened, and made changes – having more handwashing stations, passive reminders and actively having actual people reminding; further limiting access to non-petting zoo animal buildings; and, increasing cleaning and sanitation.

People brought food, strollers, and their hands touched a lot of likely contaminated handles and rails.

Over the weekend news broke of another tragic cluster of illness linked to fair/animal interactions. 

A 2-year-old boy died and three others were sickened upon contracting the E. coli virus after coming into contact with farm animals at the San Diego County Fair, according to authorities.

The child was hospitalized after visiting the county fair two weeks ago, and died Monday after complications stemming from the virus, the San Diego County Health and Human Services Agency confirmed on Friday. The other three children did not need medical attention.

The frustrating nexus of these (and all the other illnesses) is that it’s good for folks to learn about agriculture and farming and food by seeing and interacting – and that very situation is risky.

What doesn’t help is when the agricultural community scoffs at these illnesses (I haven’t heard it on this one, but have in the past) essentially saying that handwashing is common sense, so these illnesses happen because people are ignorant. Except that all falls apart because we (the folks in the know) haven’t done our job telling folks how they can manage some of the risk of getting sick, and how organizers are also trying to reduce the risk to patrons. By missing that, we’re not doing everything we can to ensure that the safe behaviors take place. And that makes me sad.

Erdozain G, Kukanich K, Chapman B, Powell D. 2012. Observation of public health risk behaviours, risk communication and hand hygiene at Kansas and Missouri petting zoos – 2010-2011. Zoonoses Public Health. 2012 Jul 30. doi: 10.1111/j.1863-2378.2012.01531.x. [Epub ahead of print]

Outbreaks of human illness have been linked to visiting settings with animal contact throughout developed countries. This paper details an observational study of hand hygiene tool availability and recommendations; frequency of risky behavior; and, handwashing attempts by visitors in Kansas (9) and Missouri (4), U.S., petting zoos. Handwashing signs and hand hygiene stations were available at the exit of animal-contact areas in 10/13 and 8/13 petting zoos respectively. Risky behaviors were observed being performed at all petting zoos by at least one visitor. Frequently observed behaviors were: children (10/13 petting zoos) and adults (9/13 petting zoos) touching hands to face within animal-contact areas; animals licking children’s and adults’ hands (7/13 and 4/13 petting zoos, respectively); and children and adults drinking within animal-contact areas (5/13 petting zoos each). Of 574 visitors observed for hand hygiene when exiting animal-contact areas, 37% (n=214) of individuals attempted some type of hand hygiene, with male adults, female adults, and children attempting at similar rates (32%, 40%, and 37% respectively). Visitors were 4.8x more likely to wash their hands when a staff member was present within or at the exit to the animal-contact area (136/231, 59%) than when no staff member was present (78/343, 23%; p<0.001, OR=4.863, 95% C.I.=3.380-6.998). Visitors at zoos with a fence as a partial barrier to human-animal contact were 2.3x more likely to wash their hands (188/460, 40.9%) than visitors allowed to enter the animals’ yard for contact (26/114, 22.8%; p<0.001, OR= 2.339, 95% CI= 1.454-3.763). Inconsistencies existed in tool availability, signage, and supervision of animal-contact. Risk communication was poor, with few petting zoos outlining risks associated with animal-contact, or providing recommendations for precautions to be taken to reduce these risks.

 

 

Papayas linked to outbreak of salmonellosis; over 60 ill

I really like fruits and berries. All kinds of fruits are my go-to snacks and over the past few years I’ve discovered how much I like tropical fruits like mango and papaya.

My favs aren’t immune from outbreaks. In 2017, an outbreak of Salmonella Anatum was linked to papaya.

And today CDC and FDA announced another outbreak of Salmonella (this time Uganda) traced to the fruit, causing at least 62 illnesses to date (with 23 hospitalizations).

According to the CDC release, there’s some notable stuff:

  • Of 33 ill people with available information, 22 reported being of Hispanic ethnicity.
  • The hospitalization rate in this outbreak is 66 percent among people with information available. The hospitalization rate in Salmonella outbreaks is usually around 20 percent.
  • Most of the sick people in this outbreak are adults over 60.

5 dead, 9 sick from Listeria in sandwiches to UK hospitals: Going public: Hugh Pennington on the shameful secrecy over the hospital sandwich scandal

I wonder if Dr. Hugh Pennington feels he’s in a Groundhog Day situation.

I know I often do.

The man who led the investigation into the 2005 E. coli O157 outbreak in the UK that killed Mason Jones and sickened about 160 children wrote in the Daily Mail the other day that,

almost two weeks have passed since news emerged of a listeria outbreak linked to ready-made sandwiches provided to patients in hospitals.

Yet until yesterday we had been told absolutely nothing beyond the names of four hospital trusts where some of the patients died or where others had fallen ill.

Last night, we learned that one of the victims was Ian Hitchcock, 52, a businessman and father of twins, from Crich in Derbyshire.

Our thoughts must go to his grieving family. But as a scientist I also have to ask why it has taken so long for even this sliver of information to be shared?

The health authorities have a duty to ensure no more people are put at risk of death. And to try to ensure that we — as doctors, scientists and indeed the wider public — all need to know more about those who got sick and recovered, or who succumbed to listeriosis, a potentially fatal form of food poisoning. This is not out of prurience, but to better safeguard the health of others.

Listeria can present in various ways — which is why diagnosis is so difficult — but among the complications are sepsis and meningitis, two of the nastiest and hardest illnesses to treat. Anyone at risk should know about it sooner rather than later.

Remarkably, and in my view wrongly, the information needed is largely being denied to us. It is only after pressure from the Daily Mail that any details at all have been released.

Tory MP Nadine Dorries, a former nurse, this week called for ‘full transparency and openness about those who have died’.

She added: ‘I don’t understand why they don’t tell us the age or sex — or what conditions they were in hospital for. All these would be relevant.’

She is right. It is in the public interest that the age, gender and reason why the victims were originally admitted to hospital are released as a matter of urgency.

If, for example, a high percentage of victims in the latest outbreak were aged over 80, then that would be helpful to know, allowing doctors and nurses to pay close attention to that demographic.

If more men than women have died — and listeria infections are generally more common in men — that would be highly relevant, too.

I’m old enough to remember the Aberdeen typhoid outbreak of 1964. In that case the names and addresses of the 400 or so infected people, who had all eaten corned beef from Argentina, were printed in the local paper almost before they’d seen a doctor. Miraculously, none of them died.

I’m not, of course, advocating a return to that level of media scrutiny. But as a bacteriologist who has spent much of his career investigating the medical consequences of poor food hygiene, I do know that — now, and for some time to come — it will be to the wider community’s benefit if there is full disclosure of facts relevant to protecting the public’s health.

In the course of my career, I’ve headed two public inquiries into outbreaks of illness caused by the better-known bacterial infection, E. coli. In both cases the public received far more information than has been released this time. One was an outbreak at schools in South Wales in 2005. This was rapidly traced back to a single butcher.

The other, which turned out to be the deadliest outbreak of this particular form of E. coli in recent British history, hit central Scotland in 1996 and was again linked to one meat supplier. A hospital, an old people’s home and a pub were all affected.

Some 21 people died in that outbreak. Thanks to strategic and considered release of information, however, doctors knew that although some children as young as 10 were infected and became seriously ill, the elderly were at the highest risk of dying. Treatment was adjusted accordingly.

Yet Public Health England (PHE) has restricted itself to a mealy-mouthed statement, saying: ‘We never confirm any information about patients affected unless there is a risk to the public’s health. Confirmation of those details is a matter for families and their doctors.’

But hang on a minute. This is an outbreak of a potentially fatal bacterial disease that has already claimed five lives in hospitals across England. We know the company at the centre of the outbreak, the Good Food Chain, supplied 43 NHS trusts, and other patients have been infected by sandwiches or salads contaminated by listeria. And we know the bacterium has a long incubation period.

So how can PHE be so certain there is no further ‘risk to the public’s health’?

The first inquests into the deaths of victims — Ian Hitchcock, who was treated at the Royal Derby Hospital, and another patient treated at Manchester Royal Infirmary where two other patients died — open tomorrow.

It is likely there will be inquests into the deaths of the other three victims, too.

But if PHE took responsibility for aggregating the information of all those who have died, stripping it of anything that could identify individuals (a particularly rare illness, for example), I believe that would safely balance confidentiality concerns with the very real need for more information.

The fact is that mounting public unease would be hugely reduced if patients, together with their concerned families, knew what the dangers were and their level of risk.

A small minority would then know they had valid concerns and could seek advice from their doctor accordingly.

The sandwiches linked to the outbreak have now been removed from the food chain, but a threat of infection remains — and will continue to do so for a few weeks yet.

We need to know who is at the highest risk — and we need that information now. Without it, there is a real danger that more people will die needlessly as a result of the authorities’ shameful silence.

Food Safety Talk 185: Hot Diapers

Don and Ben are joined by friend, listener and co-host of Do By Friday, Max Temkin. The show starts when Don surprises Ben with our special guest. Max brings the guys a bunch of great food safety questions about tomato paste and the nuances of expiration dates, sous vide, jerky and grinding your own meat. They talk about frozen berries, what triggers recalls and what they look for in a company or industry that is doing good food safety things. The episode ends on a story on how Cards Against Humanity became a food processor (sort of).

Food safety in popular culture: Scripps Spelling Bee edition

Last night I was watching the Toronto Raptors play in their first NBA finals so I missed my annual viewing of the Scripps Spelling Bee. I’ve been hooked on the spelling drama since watching Spellbound in 2002.

Campylobacter was one of the words in this year’s competition. One of my food safety nerd friends sent me the below screenshot from Instagram.

I had campy back in 2009. It sucked.

Beware of the plume: Flour linked E. coli O26 outbreak, Aldi brands recalled

I used to be a lick-the-batter-off-the-spoon kind of guy. I stopped doing that a few years ago. I don’t eat raw cookie dough, or let my kids eat it. I’m probably not the most fun dad, but outbreaks like what is going on right now is why.

According to CDC,

As of May 24, 2019, 17 people infected with the outbreak strain of E. coli O26 have been reported from 8 states. A list of the states and the number of cases in each can be found on the Map of Reported Cases page.

Illnesses started on dates ranging from December 11, 2018 to April 18, 2019. Ill people range in age from 7 to 86 years, with a median age of 23. Sixty-five percent of ill people are female. Of 17 people with information available, 3 have been hospitalized. No deaths have been reported.

Epidemiologic and laboratory evidence indicates that flour is a likely source of this outbreak.

In interviews, ill people answered questions about the foods they ate and other exposures in the week before they became ill. Of seven people who were interviewed, four (57%) reported eating, licking, or tasting raw, homemade dough or batter. Two people with detailed information reported eating raw dough or batter made with flour or baking mixes from ALDI.

Investigators with the Rhode Island Department of Health collected records and flour samples at a bakery where an ill person reported eating raw dough. Records indicated that the bakery used Baker’s Corner All Purpose Flour from ALDI. The outbreak strain was isolated from an unopened bag of Baker’s Corner All Purpose Flour collected at the bakery.

WGS results showed that the E. coli O26 strain identified in the Baker’s Corner All Purpose Flour sample was closely related genetically to the E. coli O26 strain identified in ill people. These results provide additional evidence that people in this outbreak got sick from eating flour.

On May 23, 2019, ADM Milling Co. and Aldi recalled pdf icon[PDF – 142 KB]external icon 5 lb. bags of Baker’s Corner All Purpose Flour sold at retail locations in the following states because they may be contaminated with E. coli: Connecticut, Delaware, Massachussetts, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, and West Virginia

I talked to Korin Miller at whattoexpect.com about this outbreak too, and the hidden risk factor in all of this might be cross-contamination.

It’s a good idea to take care when handling raw flour the same way as you would if you were preparing raw meat. That means washing your hands well after you touch it, sanitizing your countertops after you use it and not eating flour products until they’re thoroughly cooked, Chapman says.

Overall, you should definitely take this seriously. “It’s really, really risky to eat raw flour products,” Chapman says.

And I think about this every time I squeeze and plop down a bag of flour in my kitchen. The pathogens, if they are in there, get spread around like shrapnel.
