4 sick with campy linked to raw milk served at Royal Welsh Show

In 2013, at least 50 people, mainly children, became ill with E coli O157 at the Ekka, Queensland, Australia’s version of the state fair.

It starts again on Friday, and because organizers have done little except to encourage people to wash their hands, we won’t be going.

Handwashing is never enough.

Manure from ruminants is easily aerosolized in these environments, and I’ve been to many human-animal interaction events for research, and there is shit everywhere.

Although ostensibly designed to promote understanding of food production, these agricultural celebrations rarely discuss risk – until an outbreak happens.

The motto seems to be: It’d be better for us if you don’t understand.

Now, four people have been sickened with Campylobacter linked to unpasteurised or raw cow’s milk from Penlan y Môr farm near New Quay, Ceredigion and sold at the Royal Welsh Show.

Public Health Wales says the four cases all consumed or bought the milk at Aberystwyth Farmer’s Market after June 1.

But visitors to the Royal Welsh Show in Builth Wells may also have sampled or bought the milk which was available there on Wednesday, 26 July.

Observation of public health risk behaviors, risk communication and hand hygiene at Kansas and Missouri petting zoos – 2010-2011Outbreaks 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.

Educational events encouraging human–animal interaction include the risk of zoonotic disease transmission. It is estimated that 14% of all disease in the US caused by Campylobacter spp., Cryptosporidium spp., Shiga toxin-producing Escherichia coli (STEC) O157, non-O157 STECs, Listeria monocytogenes, nontyphoidal Salmonella enterica and Yersinia enterocolitica were attributable to animal contact. This article reviews best practices for organizing events where human–animal interactions are encouraged, with the objective of lowering the risk of zoonotic disease transmission.

Going public fail: 14 sick with E. coli linked to raw milk in Virginia, 2016

The general public didn’t have access to the suspect food, so there was no point in unnecessarily alarming the public.

I’ve heard that paternalistic crap for 30 years now, and it never turns out well.

Coral Beach of Food Safety News reports that Virginia officials did not alert the general public to an E. coli outbreak in March 2016 that sickened at least 14 people — a dozen of them children.

This week, 17 months after the outbreak, public health officials expect to complete their report on the incident, according to a spokesman for the Virginia Department of Health. The implicated milk was from Golden Valley Guernseys (free samples delivered for $4) dairy, which sent a letter to members of its herd-share operation alerting them to the illnesses at the time.

Of the 14 confirmed E. coli victims, half had symptoms so severe that they required hospitalization. Three developed hemolytic uremic syndrome.

The state health department’s Rappahannock-Rapidan Health District office did not make a public announcement about the outbreak at the time because the general public did not have access to the milk, District Director Dr. Wade Kartchner told Food Safety News.

“Consideration was given to putting out a broad public notice, but the nature of the herd-share programs are such that we were confident that we would be able to effectively reach those who were truly at risk of illness,” Kartchner said. “… it is not quite the same situation as a restaurant outbreak where the public at large may be exposed.”

This is so wrong.

Others, even mere mortals, learn from outbreaks: How did this happen? How dangerous was the outbreak? And what kind of foods to avoid, like raw fucking milk.

In the absence of public announcements, it also makes it harder for mere scientists to make a case that a certain food may be risky.

Going public is the new normal for foodborne outbreaks, and some day, admin-types may catch up.

Facebook, tweets, calls to lawyers like Marler, going public is any agency’s best defense.

And it’s the right thing to do.

We’ve published about this before, and as I said at the time, I’ve had different versions of this paper running through my head for 25 years.

It started as a rebel-without-a-clue teenager, and led to questions about mad cow disease in 1995 (or earlier) when the UK government knew there were human victims but said nothing until March 1996.

Yet the job of public health, no matter how many political assholes, no matter how many impediments, and no matter how many dog bites you have to investigate, is to protect public health.

If people are barfing, it’s time to go public.

That doesn’t always happen.

Anyone can search barfblog.com under the phrase “going public” and find hundreds of incidents of people acting like shits.

But this is important shit, because credibility depends on transparency and trust and truthiness (at least in my idyllic world-view).

Public health is under siege.

The science is there, the outbreaks are there. Go public.

Or at least explain the process so the rest of us can understand.

Going public: Early disclosure of food risks for the benefit of public health

Often during an outbreak of foodborne illness, there are health officials who have data indicating that there is a risk prior to notifying the public. During the lag period between the first public health signal and some release of public information, there are decision makers who are weighing evidence with the impacts of going public.

Multiple agencies and analysts have lamented that there is not a common playbook or decision tree for how public health agencies determine what information to release and when. Regularly, health authorities suggest that how and when public information is released is evaluated on a case-by-case basis without sharing the steps and criteria used to make decisions. Information provision on its own is not enough.

Risk communication, to be effective and grounded in behavior theory, should provide control measure options for risk management decisions.

There is no indication in the literature that consumers benefit from paternalistic protection decisions to guard against information overload. A review of the risk communication literature related to outbreaks, as well as case studies of actual incidents, are explored and a blueprint for health authorities to follow is provided.

Listeria in the news again

 

Food company Ready to Eat has announced a Listeria outbreak in several of their pre-packaged meals.
Ready to Eat, which produces ‘Muscle Fuel’ pre-made meals, said the meals affected are the ‘Vegetarian Chickpea and Pumpkin Rosti on Spinach Salad’ and the ‘Turkish Style Chicken & Rice’ with best before dates of August 4th, August 5th, August 6th, 2017.
Other meals are unaffected, the company says.
Any customers in possession of one of the affected meals are being urged to discard it immediately.
In a statement, Ready to Eat CEO Hamish Coulter said they were horrified when they received the news.
“To learn that one of our trusted produce suppliers has let us down is extremely disappointing.”
The Hamilton-based company was informed on Friday afternoon that its supplier Vegeez had returned a positive result for Listeria in one of its recent batches of cabbage.
On Friday evening the company contacted the 139 customers affected.
Vegeez general manager Glen Reid said it had taken full responsibility for the “very rare” event.
Mr Reid said in total there were 15 companies supplied with the affected cabbage, but all other companies managed to dump the product before using it.
Mr Coulter apologised to the company’s customers and said they were putting in measures to ensure this did not happen again.
The company has discontinued the use of coleslaw for the foreseeable future.
If any customer has consumed what they believe to be a contaminated meal they are advised to seek medical advice.
All customers will be contacted again this week with refunds issued.

I stumbled across an interested paper published in the Journal of Food Protection in February 2017 investigating the fate of Listeria monocytogenes , pathogenic Yersinia enterocolitica , and Escherichia coli O157:H7 gfp+inoculated in low numbers into ready-to-eat baby spinach and mixed-ingredient salad (baby spinach with chicken meat).

A quick synopsis of the study showed that when mixed-ingredient salad was stored at 8°C during shelf life, only L. monocytogenes increased significantly, reaching 3.0 log CFU/g within 3 days. The 8°C reflects maximum refrigerator temperature storage in Sweden.

In plain baby spinach, only pathogenic Y. enterocolitica populations increased significantly during storage for 7 days, and this was exclusively at an abuse temperature (15°C). Thus, mixing ready-to-eat leafy vegetables with chicken meat strongly influenced levels of inoculated strains during storage. 

The authors then translated the numbers into risks of infection. The risk of listeriosis (measured as probability of infection) was 16 times higher when consuming a mixed-ingredient salad stored at 8°C at the end of shelf life, or 200,000 times higher when stored at 15°C, compared with when consuming it on the day of inoculation. They conclude that efforts should focus on preventing temperature abuse during storage to mitigate the risk of listeriosis.

You’d think government could do the same.

At least 5 sick with crypto: Raw milk from Moo View Dairy recalled by South Australian health types

There was this one time, about 1979, when me and my high school buddies fell into some tickets for Can-Am car racing, which none of us cared about.

So we stayed up all night as high school students do, and then I was the designated driver to Mosport, Ontario, a few hours away.

On the way we stopped at a truck stop off the 401 near Bowmanville, Ontario, and my friends, who were quite stoned, couldn’t stop laughing about the moo-moo cow creamer on every table.

It was pasteurized.

The stuff from Willunga Hill’s Moo View Dairy is not, and the dairy will be prohibited from selling and distributing raw cow’s milk after it was linked to at least five cases of gastroenteritis.

Brad Crouch, medical reporter at The Advertiser, writes, SA Health has taken the action under the Food Act 2001 and the South Australian Public Health Act 2011, after the sicknesses were linked to drinking unpasteurised (raw) cow’s milk.

SA Health Director of Public Health Associate Professor Kevin Buckett said the sale of raw cow’s milk for human consumption is illegal in Australia due to its high risk of contamination.

“We’ve confirmed at least five cases where people aged between three and 70 contracted gastrointestinal illness caused by the Cryptosporidium parasite after consuming raw cow’s milk products purchased from Moo View Dairy, and this number is likely to be higher,” he said.

“Luckily, these people did not require hospitalisation, but it is important to remember that raw cow’s milk products should not be consumed as they can contain harmful bacteria such as E.coli, salmonella, campylobacter, and listeria, as well as cryptosporidium.

“In June we noticed higher than expected numbers of cryptosporidiosis cases and following interviews and investigations, we identified Moo View Dairy’s raw cow’s milk as a common factor between five cases,” Assoc Prof Buckett said.

“We’ve also identified another two potential cases that implicate raw cow’s milk as the cause of illness.

And the next year, Mosport had this (and yes, that’s John (J.D.) Roberts doing some of the interviews for Much Music. He can be now found as chief White House correspondent for Fox News (gag me). Oh, and I arranged Teenage Head to play our high school in 1979.

Raw is risky.

Hepatitis E: Raw pork is main cause of infection in EU

Consumption of raw or undercooked pork meat and liver is the most common cause of hepatitis E infection in the EU, said the European Food Safety Authority.

More than 21,000 cases of hepatitis E infections have been reported in humans over the last 10 years, with an overall 10-fold increase in this period.

Rosina Girones, chair of EFSA’s working group on hepatitis E, said: “Even if it is not as widespread as other foodborne diseases, hepatitis E is a growing concern in the EU. In the past, people thought the main source of infection was drinking contaminated water while travelling outside the EU. But now we know the main source of transmission of the disease in Europe is food.”

Domestic pigs are the main carriers of hepatitis E in the EU. Wild boars can also carry the virus, but meat from these animals is less commonly consumed.

Experts from EFSA’s Panel on Biological Hazards recommend that Member States increase awareness of public health risks associated with raw and undercooked pork meat and advise consumers to cook pork meat thoroughly. They also recommend the development of suitable methods for detecting hepatitis E in food.

This scientific advice builds on a previous scientific opinion on the occurrence and control of foodborne viruses published in 2011.

The European Centre for Disease Prevention and Control (ECDC) has today also published a report on hepatitis E in humans which assesses testing, diagnosis and monitoring methods and reviews available epidemiological data.

Hepatitis E is a liver disease caused by the hepatitis E virus (HEV).

Most people who contract hepatitis E display no or mild symptoms. However, in some cases especially for those with liver damage or patients with a weak immune system, it can lead to liver failure – which can be fatal.

21 sick with Salmonella: Australia still has an egg problem, Melbourne fairytale edition

You’ve got to be fucking kidding.

Another day, another outbreak of Salmonella traced to some Master-Chef-inspired raw egg food porn.

Paddy Naughtin of the Whitehorse Leader writes that a bad batch of eggs is being blamed for 21 people being struck down by a Salmonella outbreak believed to have been picked up at a Blackburn restaurant.

The Department of Health and Human Services and Whitehorse Council are still investigating the cause of the outbreak which affected at least 21 people who ate at the Food Republic on Blackburn Rd on March 18.

Food Republic co-owner Vanessa Lekkas said she was “genuinely distraught” for those who had been affected and was “humbled by their understanding” .

“In almost 30 years of working in the industry we’ve never seen this happen,” Ms Lekkas said.

“We get hundreds of boxes delivered each week, and it looks like one of those contained a bad batch of eggs.

“We’ve been fully transparent with the council and health authorities, and they’ve seen our food handling processes are up to scratch.

“We’ve been told the investigation is now looking at the farms where the eggs came from,” Ms Lekkas said.

Ms Lekkas said the Food Republic would no longer be serving food made with raw egg products.

Why the fuck didn’t they stop years ago?

There’s been plenty of outbreaks, plenty of publicity, but, humans being humans, they think it won’t happen to them.

I get that.

So in the interest of public health, Australians, stop serving raw egg dishes.

And food porn chefs who are food safety idiots, fuck off.

Your wellness guidelines are making people sick.

Health-types, up your game.

Fall fairytale: Lawsuit filed after crypto-in-apple-cider sickened more than 100 in 2015

In Oct. 2015, fall festival revellers flocked to the Pike Country Color Drive in Pike County, Illinois, and a bunch of them were soon barfing.

Unpasteurized apple cider – a staple of the northern U.S. and Canadian fall festival circuit was blamed for causing more than 100 people to fall ill with cryptosporidiosis.

Nick Draper of My Journal Courier reports a lawsuit has now been files against several groups, including the Pike County Chamber of Commerce and the Barry Business Association.

Melissa Kinman of Quincy filed the civil action against Steven and Linda Yoder of Yoder Brothers Dairy Farm, the Pike County Chamber of Commerce and the Barry Business Association. In it, she contends the Yoders were selling and offering free samples of unpasteurized cider that was tainted with Cryptosporidium.

The outbreak sickened people ranging in age from less than 1 year old to 89 years old.

Health workers from Pike and Adams counties, the state and the Centers for Disease Control and Prevention began investigating reports of profuse or bloody diarrhea, abdominal cramping and vomiting. Tests done in December 2015 by the CDC confirmed there was cider contaminated with Cryptosporidium.

Cider was not sold at last year’s drive after officials decided to pull the product.

A list of cider and juice-related outbreaks — 84 outbreaks leading to over 3,500 illnesses going back to 1924 – is available here.

11 kids sickened: Campy from a dairy farm visit in Sweden

In April–May 2014, an outbreak of campylobacteriosis occurred after a preschool visit to a dairy farm in the South Western part of Sweden. During the visit, a meal, including unpasteurized milk, was served.

A retrospective cohort study using a web-based questionnaire was performed among the participants (n = 30) of the farm visit. A total of 24 of the 30 (80%) cohort members completed the questionnaire. Eleven cases were identified, and Campylobacter jejuni was isolated from eight of them. Seven of the cases were 2- to 7-year-old children. We found the highest attack rates among those who usually drink milk (45%) and those who consumed unpasteurized milk during the farm visit (42%). No cases were unexposed (risk ratio incalculable).

As result of the farm investigation, Campylobacter was isolated from cattle on the farm. Genotyping with pulsed-field gel electrophoresis and whole genome sequencing confirmed that human and cattle isolates of C. jejuni belonged to one cluster.

Thus, cattle on the farm are considered the source of infection, and the most likely vehicle of transmission was contaminated unpasteurized milk. We recommend consumption of heat-treated milk only and increased awareness of the risk of consuming unpasteurized milk.
