Sprouts sicken at least 8 linked to Jimmy John’s: It’s all happening, again

I got invited by one of my former students to give a talk about food safety stuff at an American military base in Germany, about 2012.

This was after 5,500 people became sick and 53 died from E. coli O104 linked to raw sprouts, primarily in Germany.

Met a couple of lifelong friends, continued my work with the U.S. military, because those folks need to eat too, and learned that public bathroom in Germany is an oxymoron and people just piss at the side of the road (Australia has excellent public bathrooms, best I’ve ever seen).

After my presentation, one of my military friends said, guess you’re not a fan of Jimmy John’s.

I said, no, I’m not a fan of bullshit.

Before the U.S. government shut down, the folks at the Centers for Disease Control managed to publish the latest outbreak info of Salmonella linked to raw sprouts in Jimmy Johns subs, the preferred lunch meeting snack for Kansas State University food professors, who know nothing about safety.

To recap:

An outbreak linked to raw sprouts in the U.S. that sickened 140 people occurred between November 2010 into 2011, involving sandwich franchise, Jimmy John’s (CDC, 2011; Illinois Department of Public Health, 2010).

The owner of the Montana Jimmy John’s outlet, Dan Stevens, expressed confidence in his sprouts claiming that because the sprouts were locally grown they would not be contaminated, although the source of the contaminated sprouts had not yet been identified (KRTV, 2010).

By the end of December 2010 a sprout supplier, Tiny Greens Farm, was implicated in the outbreak (Food and Drug Administration, 2010).

Jimmy John’s owner, John Liautaud, responded by stating the sandwich chain would replace alfalfa sprouts with clover sprouts since they were allegedly easier to clean (Associated Press, 2011c). However, a week earlier a separate outbreak had been identified in Washington and Oregon (still miss ya, Bill Keene) in which eight people were infected with Salmonella after eating sandwiches containing clover sprouts from a Jimmy John’s restaurant (Oregon Department of Human Services, 2011; Terry, 2011). This retailer was apparently not aware of the risks associated with sprouts, or even outbreaks associated with his franchisees.

The FDA inspection of the Tiny Greens facility found numerous issues which may have led to pathogen contamination, including “the company grew sprouts in soil from the organic material decomposed outside without using any monitored kill step on it,” mold was found in the mung-bean sprouting room, and the antimicrobial treatment for seeds was not demonstrated to be equivalent to the recommended FDA treatment (Roos, 2011).

Months later, Bill Bagby Jr, owner of Tiny Greens, was quoted as saying “after the changes we made, it’s next to impossible for anything to happen,” hindering communication efforts by being defensive and overconfident (Des Garennes, 2011; Sandman & Lanard, 2011). Bagby also expressed confidence in sprouts following the German outbreak, commenting that for many like him, the nutritional benefits outweigh the risk: “Sprouts are kind of a magical thing. That’s why I would advise people to only buy sprouts from someone who has a (food safety) program in place (that includes outside auditors). We did not have (independent auditors) for about one year, and that was the time the problems happened. The FDA determined that unsanitary conditions could have been a potential source of cross-contamination and so we have made a lot of changes since then.”

In the second week of October, 2013, three Jimmy John’s restaurants in the Denver Metro area reportedly served up sandwiches that sickened eight people with E. coli bacteria.

“We believe that their illness came from a produce item that was on those sandwiches that they ate,” said Alicia Cronquit, epidemiologist with the Colorado Department of Public Health and Environment.

Cronquist said all eight cases were reported between October 18th and 22nd, and all of the people impacted ate at Jimmy John’s between October 7th and 15th.

The Department of Public Health has not closed down the three restaurants, and will not identify their locations because Cronquist says they do not believe the restaurants are at fault.

“Our leading hypothesis for what’s happened is that there was a contaminated produce item that was distributed to the stores,” Cronquist said. “We have not identified any food handling issues at the particular establishments that we think would contribute to illness.”

Raw sprouts are the poster child for failures in what academics call risk communication.

About 1999, graduate student Sylvanus Thompson started working with me on risk analysis associated with sprouts. He got his degree and went on to rock-star status in the food safety world with the implementation of the red-yellow-green restaurant inspection disclosure program with Toronto Public Health, but we never published anything.

I remember frantically flying to Kansas City to hang out with this girl in Manhattan (Kansas) I’d met a couple of weeks before, in the midst of the 2005 Ontario raw sprout outbreak that sickened over 700; Jen Tryon, now with Global News, interviewed me at the airport, with me wearing a K-State hockey shirt (that’s the joke; there is no hockey at K-State, and I was still employed by Guelph; and I was going to hang out with this girl).

After the German E. coli O104 outbreak, along with the ridiculous public statements and blatant disregard for public safety taken by sandwich artist Jimmy John’s in the U.S., I figured we really needed to publish something.

The basic conclusions:

  • raw sprouts are a well-documented source of foodborne illness;
  • risk communication about raw sprouts has been inconsistent; and,
  • continued outbreaks question effectiveness of risk management strategies and producer compliance.

We document at least 55 sprout-associated outbreaks occurring worldwide affecting a total of 15,233 people since 1988. A comprehensive table of sprout-related outbreaks can be found here.

Sprouts present a unique food safety challenge compared to other fresh produce, as the sprouting process provides optimal conditions for the growth and proliferation of pathogenic bacteria. The sprout industry, regulatory agencies, and the academic community have been collaborating to improve the microbiological safety of raw sprouts, including the implementation of Good Manufacturing Practices (GMP), establishing guidelines for safe sprout production, and chemical disinfection of seed prior to sprouting. However, guidelines and best practices are only as good as their implementation. The consumption of raw sprouts is considered high-risk, especially for young, elderly and immuno-compromised persons (FDA, 2009).

In late December 2011, less than one year after making the switch to clover sprouts, Jimmy John’s was linked to another sprout related outbreak, this time it was E.coli O26 in clover sprouts. In February 2012, sandwich franchise Jimmy John’s announced they were permanently removing raw clover sprouts from their menus. As of April 2012, the outbreak had affected 29 people across 11 states. Founder and chief executive, John Liautaud, attempted to appease upset customers through Facebook stating, “a lot of folks dig my sprouts, but I will only serve the best of the best. Sprouts were inconsistent and inconsistency does not equal the best.” He also informed them the franchise was testing snow pea shoots in a Campaign, Illinois store, although there is no mention regarding the “consistency” or safety of this choice.

In spite of widespread media coverage of sprout-related outbreaks, improved production guidelines, and public health enforcement actions, awareness of risk remains low. Producers, food service and government agencies need to provide consistent, evidence-based messages and, more importantly, actions. Information regarding sprout-related risks and food safety concerns should be available and accurately presented to producers, retailers and consumers in a manner that relies on scientific data and clear communications.’

On Friday, Jan. 19, 2018, CDC along with public health and regulatory officials in several states, and the U.S. Food and Drug Administration (FDA) announced a multistate outbreak of Salmonella Montevideo infections that has sickened at least eight people.

Illnesses started on dates ranging from December 20, 2017 to January 3, 2018. Ill people range in age from 26 to 50, with a median age of 34. All 8 (100%) are female. No hospitalizations and no deaths have been reported.

Epidemiologic evidence indicates that raw sprouts served at Jimmy John’s restaurants are a likely source of this multistate outbreak.

In interviews, ill people answered questions about the foods they ate and other exposures in the week before they became ill. Seven (88%) of eight people interviewed reported eating at multiple Jimmy John’s restaurant locations. Of these seven people, all seven (100%) reported eating raw sprouts on a sandwich from Jimmy John’s in Illinois and Wisconsin. This proportion is significantly higher than results from a survey[PDF – 29 pages] of healthy people, in which 3% reported eating sprouts on a sandwich in the week before they were interviewed. Two ill people in Wisconsin ate at a single Jimmy John’s location in that state.

Federal, state, and local health and regulatory officials are conducting traceback investigations from the six Jimmy John’s locations where ill people ate raw sprouts. These investigations are ongoing to determine where the sprouts were distributed, and to learn more about the potential route of contamination.

The information available to date indicates that raw sprouts served at Jimmy John’s restaurants in Illinois and Wisconsin may be contaminated with Salmonella Montevideo and are not safe to eat. CDC recommends that consumers not eat raw sprouts served at Jimmy John’s restaurants in Illinois and Wisconsin.

Failures in sprouts-related risk communication

Nutritional and perceived health benefits have contributed to the increasing popularity of raw sprouted seed products. In the past two decades, sprouted seeds have been a recurring food safety concern, with at least 55 documented foodborne outbreaks affecting more than 15,000 people. A compilation of selected publications was used to yield an analysis of the evolving safety and risk communication related to raw sprouts, including microbiological safety, efforts to improve production practices, and effectiveness of communication prior to, during, and after sprout-related outbreaks. Scientific investigation and media coverage of sprout-related outbreaks has led to improved production guidelines and public health enforcement actions, yet continued outbreaks call into question the effectiveness of risk management strategies and producer compliance. Raw sprouts remain a high-risk product and avoidance or thorough cooking are the only ways that consumers can reduce risk; even thorough cooking messages fail to acknowledge the risk of cross-contamination. Risk communication messages have been inconsistent over time with Canadian and U.S. governments finally aligning their messages in the past five years, telling consumers to avoid sprouts. Yet consumer and industry awareness of risk remains low. To minimize health risks linked to the consumption of sprout products, local and national public health agencies, restaurants, retailers and producers need validated, consistent and repeated risk messaging through a variety of sources.

 

 

European Food Safety Authority: Update on Salmonella agona outbreak

The withdrawal and/or recall of infant formula produced by a single French processing company will significantly reduce the risk of more infants being infected by Salmonella Agona, say EFSA and ECDC as a result of a rapid outbreak assessment.

An outbreak of S. Agona linked to the consumption of infant formula has been ongoing in France since August 2017. So far the outbreak has affected 37 children under one year of age in France. Whole genome sequencing (WGS) analysis confirmed that a Spanish case is closely related to the outbreak in France. A probable case has been identified in Greece. The last case was notified on 2 December 2017.

EFSA and ECDC recommend that competent authorities in affected Member States keep sharing information on the epidemiological, microbiological and environmental investigations and issue relevant notifications in the Rapid Alert System for Food and Feed (RASFF) and the Early Warning Response System (EWRS).

To prevent infections using infant formulas, both in infants and caregivers, Member States should consider providing advice to the public regarding:

Not to use any of the infant formulas involved in this outbreak;

Hand washing before and after the preparation of the bottle;

Bottles should not be prepared in advance and the contents should be discarded if not consumed within two hours.

What is a rapid outbreak assessment?

In case of multi-country foodborne outbreaks coordination at EU level is important. A Rapid Outbreak Assessment is jointly prepared by EFSA and ECDC in close cooperation with affected countries. The ROA gives an overview of the situation in terms of public health and identifies the contaminated food vehicle that caused the infections. It also includes trace-back and trace-forward investigations to identify the origin of the outbreak and where contaminated products have been distributed. This is crucial to identify the relevant control measures in order to prevent further spread of the outbreak.

An outbreak of Salmonella Agona linked to the consumption of infant formula (powdered milk) has been ongoing in France since August 2017. As of 11 January 2018, the outbreak had affected 39 infants (children <1 year of age): 37 in France, one in Spain confirmed by whole genome sequencing (WGS) and one in Greece, considered to be associated with this event based on the presence of a rare biochemical characteristic of the isolate.

The date of symptom onset for the most recent case was 2 December 2017. Available evidence from epidemiological investigations in humans and traceability investigations in food identified seven different brands of infant formula from a single processing company in France as the vehicles of infection.

After receiving the first notification on 2 December 2017 of an unusual number of S. Agona cases in France, the French authorities carried out investigations at the implicated factory. On 4 December 2017, they notified the Rapid Alert System for Food and Feed (RASFF) after confirming that some of the affected products were exported to other countries. Following investigations at the processing company, all products manufactured since 15 February 2017, including products other than infant formula, have been recalled and/or withdrawn, as a precautionary measure. The French competent authorities are verifying that the measures taken by the processing company in response to this event have been sufficient and appropriate. As of 15 January 2018, recalled products had been distributed to 13 European Union (EU) countries (Belgium, Bulgaria, Cyprus, the Czech Republic, France, Greece, Ireland, the Netherlands, Romania, Slovenia, Slovakia, Spain and the United Kingdom) and to 54 third countries. Most of the batches involved in the investigation have not yet passed their expiry date. However, broad withdrawal and/or recall measures, export bans and a suspension of market distribution of these batches, implemented since the beginning of December 2017 by the French competent authority and processing company A, are likely to significantly reduce the risk of human infection. The possibility remains, however, that new cases may be detected. Third countries, where the recalled products had been distributed, have been notified by RASFF through INFOSAN. ECDC offers WGS services to EU/EEA countries that do not have the capacity for a timely sequencing and analysis as part of this investigation. A multi-country WGS analysis is under way at the Pasteur Institute.

Whole genome sequencing is just a technique, with pros and cons: Australia still has a (raw) egg problem

In Australia, the incidence of Salmonella Typhimurium has increased dramatically over the past decade. Whole-genome sequencing (WGS) is transforming public health microbiology, but poses challenges for surveillance.

To compare WGS-based approaches with conventional typing for Salmonella surveillance, we performed concurrent WGS and multilocus variable-number tandem-repeat analysis (MLVA) of Salmonella Typhimurium isolates from the Australian Capital Territory (ACT) for a period of 5 months. We exchanged data via a central shared virtual machine and performed comparative genomic analyses. Epidemiological evidence was integrated with WGS-derived data to identify related isolates and sources of infection, and we compared WGS data for surveillance with findings from MLVA typing.

We found that WGS data combined with epidemiological data linked an additional 9% of isolates to at least one other isolate in the study in contrast to MLVA and epidemiological data, and 19% more isolates than epidemiological data alone. Analysis of risk factors showed that in one WGS-defined cluster, human cases had higher odds of purchasing a single egg brand. While WGS was more sensitive and specific than conventional typing methods, we identified barriers to uptake of genomic surveillance around complexity of reporting of WGS results, timeliness, acceptability, and stability.

In conclusion, WGS offers higher resolution of Salmonella Typhimurium laboratory surveillance than existing methods and can provide further evidence on sources of infection in case and outbreak investigations for public health action. However, there are several challenges that need to be addressed for effective implementation of genomic surveillance in Australia.

Seek and ye shall find: Citrobacter in pre-cut veggies in a German hospital sickened 76

A foodborne outbreak of VIM carbapenemase-expressing Citrobacter freundii (CPC) occurred between February and June 2016 at a major university hospital in Germany.

An explosive increase of CPC isolated from rectal swabs of patients during weekly routine screening led to the declaration of an outbreak. A hospital-wide prevalence screening was initiated as well as screening of all patients on admission and before transfer to another ward, and canteen staff, patient rooms, medical and kitchen inventory and food. Swabs were streaked out on selective plates. All CPC isolates were analysed by mass spectrometry and selected isolates by whole-genome sequencing.

In total, 76 mostly unrelated cases in different wards were identified. The CPC was isolated from retained samples of prepared vegetable salads and puddings and from a mixing machine used to prepare them only after an overnight culture. The immediate ban on serving potential source food resulted in a sharp decline and finally disappearance of novel cases. Repeated testing of pre-sliced vegetables showed a high degree of contamination with C. freundii without a carbapenemase, indicating a possible source.

This report demonstrates that an explosive increase in carbapenemase-expressing Enterobacteriaceae contamination may be caused by a foodborne source, and suggests that pre-sliced vegetables have to be taken into account as a putative pathogen repository. It also underlines the importance of appropriate cooling, transport, re-heating and distribution of meals and indicates that probing of non-organic surfaces is limited by low sensitivity, which may be increased by additional overnight cultivation in appropriate media.

Cilantro has a history of shits: Produce risk modelling in India

This study estimates illness (diarrhea) risks from fecal pathogens that can be transmitted via fecal-contaminated fresh produce. To do this, a quantitative microbial risk assessment (QMRA) framework was developed in National Capital Region, India based on bacterial indicator and pathogen data from fresh produce wash samples collected at local markets.

Produce wash samples were analyzed for fecal indicator bacteria (Escherichia coli, total Bacteroidales) and pathogens (Salmonella, Shiga-toxin producing E. coli (STEC), enterohemorrhagic E. coli (EHEC)). Based on the E. coli data and on literature values for Cryptosporidium and norovirus, the annual mean diarrhea risk posed by ingestion of fresh produce ranged from 18% in cucumbers to 59% in cilantro for E. coli O157:H7, and was <0.0001% for Cryptosporidium; for norovirus the risk was 11% for cucumbers and up to 46% for cilantro. The risks were drastically reduced, from 59% to 4% for E. coli O157:H7, and from 46% to 2% for norovirus for cilantro in post-harvest washing and disinfection scenario.

The present QMRA study revealed the potential hazards of eating raw produce and how post-harvest practices can reduce the risk of illness. The results may lead to better food safety surveillance systems and use of hygienic practices pre- and post-harvest.

Jimmy Johns linked to sprout outbreak again

I can’t remember if this is outbreak number 3 or 4 (oops, it’s number 5 according to the Chicago Tribune) but Jimmy Johns, the sub folks, have been linked to a bunch of salmonellosis illnesses through sprouts again.

I wonder if their PR folks regret this sprout marketing ploy (right, exactly as shown) from a few years ago. Skull. Crossbones. Eat at your own risk. Nudge. Nudge. Say no more.

Yeah. And there are illnesses again.

“Food safety and the welfare of our customers are our top priorities and not negotiable in our business,” said James North, Jimmy John’s President and CEO, in a news release, adding the company is working with the various agencies in the investigation.

Here’s a table of over 75 sprout-related outbreaks going back to 1973. We’ll add this one when there are more details.

Nudge. Nudge.

 

Eating sushi can be risky

I dry heaved when I read this…..

Michelle Robertson of SF Gate reports

A Fresno man with a daily sushi habit had a 5.5-foot tapeworm lodged in his intestines. He pulled it out himself, wrapped it around a cardboard toilet paper tube and carried the creature into Fresno’s Community Regional Medical Center.
Kenny Bahn was the lucky doc on shift at the time. He recounted his experience on a recent episode of the podcast “This Won’t Hurt A Bit.”
Bahn said the patient complained of “bloody diarrhea” and expressed a desire to get treated for tapeworms.
“I get asked this a lot,” the doctor said. “Truthfully, a lot of times I don’t think they have it.”
This man had it, which he proved to Bahn by opening a plastic grocery bag and pulling out the worm-wrapped toilet paper tube.
Bahn then asked some questions, starting with: “That came out of your bottom?”
“Yes.” 
According to the doctor’s retelling, the patient was using the restroom when he noticed what looked like a piece of intestine hanging out of his body.
Doctors in Taiwan extracted an 8-and-a-half foot tapeworm from a girl’s intestine and believe she contracted the parasite through raw, contaminated fish.
“He grabs it, and he pulls on it, and it keeps coming out,” Bahn recounted. He then picks the thing up, “looks at it, and what does it do? It starts moving.” (Note: At this point in the podcast, the hosts audibly gasp.)
That’s when the man realized he had a tapeworm stuck in his insides. He headed to the emergency room shortly thereafter, where Bahn treated him with an anthelmintic, a single-treatment deworming medication used on humans and dogs alike.
Bahn also took it upon himself to measure the specimen on the floor of the hospital. It stretched a whopping 5 feet, 6 inches — “my height,” noted the doctor.
Tapeworms can be contracted in a variety of ways, but Bahn said his patient hadn’t traveled out of the country or engaged in any out-of-the-ordinary behavior. The man also professed his love of sushi, specifically raw salmon sashimi, which he confessed to eating daily.
Fresno is located an ample 150 miles from coastline and is not exactly famed for its sushi. The Centers for Disease Control and Prevention warned last February that the rise in popularity of raw fish consumption has likely spurred a recent increase of tapeworm infections.

 

Foodborne disease outbreaks in the United States: A historical overview

Understanding the epidemiology of foodborne disease outbreaks (FBDOs) is important for informing investigation, control, and prevention methods.

We examined annual summary FBDO data in the United States from 1938 to 2015, to help understand the epidemiology of outbreaks over time. Due to changes in reporting procedures, before 1998, the mean number of annual outbreaks was 378, and after that, it was 1062.

A mean of 42% had a known etiology during 1961–1998; since then the etiology has been identified in ∼65%, with a marked increase in the number of norovirus outbreaks. From 1967 to 1997, a mean of 41% of FBDOs occurred in restaurant settings, increasing to 60% in 1998–2015. Concurrently, the proportion of outbreaks occurring at a home decreased from 25% to 8%.

The mean size of outbreaks has decreased over time, and the number of multistate outbreaks has increased. Many social, economic, environmental, technological, and regulatory changes have dramatically affected the epidemiology of foodborne disease over time.

Teens injesting laundry detergent in what’s dubbed the Tide pod challenge

CBS News reports that in this latest social media fad, teenagers are putting detergent pods in their mouths in what’s being called the “Tide Pod Challenge.”

Ingredients in the pods include ethanol, hydrogen peroxide and polymers – a highly-toxic mix of detergent meant to wipe out dirt and grime. Manufacturers have been concerned about toddlers mistakenly ingesting them, but now teens are popping them on purpose and posting videos of the results online, reports CBS News correspondent Anna Werner.

Nineteen-year-old Marc Pagan, who did it on a dare, told CBS News he knew better but did it anyway.

“A lot of people were just saying how stupid I was or how – why would I be willing to do that,” he said. “No one should be putting anything like that in their mouths, you know?”

Ann Marie Buerkle, acting chairman of the Consumer Product Safety Commission, says ingesting any of the liquid carries a deadly risk.

“This is what started out as a joke on the internet and now it’s just gone too far,” Buerkle said.

The pods are bright and colorful and to children they can look like candy. At least 10 deaths have been linked to ingesting these pods. Two were toddlers, eight were seniors with dementia.

Procter & Gamble, the maker of Tide products, told CBS News: “They should not be played with… Even if meant as a joke. Safety is no laughing matter.”

More than 62,000 children under the age of six were exposed to laundry and dishwasher detergents, between 2013 and 2014.

The next year, Consumer Reports said it would no longer recommend detergent packets, citing “the unique risks” while urging the “adoption of tougher safety measures.”

“Laundry detergent pods are highly concentrated detergent,” says Tammy Noble, a registered nurse and spokeswoman for the Iowa Poison Control Center. “Biting into them can cause diarrhea, some vomiting and sometimes that vomiting can even go on and on, excessive vomiting where we worry about it leading into dehydration.” Even if it’s being done as a joke and the person never intends to swallow the detergent, biting into the pod will likely make it squirt right down their gullet.

“It can cause burns in the mouth, the throat and the stomach,” Noble says. “Or there’s been cases where it accidentally gets into the lungs, where they aspirate it. That can cause significant breathing problems and sometimes that patient needs to be put on a ventilator to help them breathe.”
