63 sick: Wisconsin band students suffer ‘violent’ illness at Indy championship game

Dozens of University of Wisconsin-Madison band members suffered illnesses during Saturday’s Big Ten Championship football game in Indianapolis, a university spokeswoman said.

wisconsin-barf-bandUW-Madison media relations Director Meredith McGlone told News 3 that just before kickoff Saturday night, some members of the UW Marching Band began experiencing nausea, diarrhea and vomiting. As the game progressed, more members fell ill and were treated by onsite medical personnel. UW Band Director Mike Leckrone said most students started getting sick right before half time.

“Nobody had to run off the field, thankfully,” Leckrone said. “But there were a few that the moment they got off the field, they headed for the garbage can. They probably shouldn’t have gone on, they were feeling a little queasy. But it gets to be the call of the show time, and they wanted to perform.”

 

STEC surveillance: EU edition

On 1 December 2016 the third version of the Epidemic Intelligence Information System for food- and waterborne diseases and zoonoses (EPIS-FWD) was launched. With this development, the European Centre for Disease Prevention and Control (ECDC) moved one step further towards the One Health approach.

In collaboration with the European Food Safety Authority (EFSA), the Molecular Typing Cluster Investigation (MTCI) module was expanded to also allow the assessment of Salmonella, Shiga toxin-producing Escherichia coli (STEC) and Listeria monocytogenes microbiological clusters based on non-human isolates (i.e. food, feed, animal and environmental) and on a mix of non-human and human isolates.

Depending on the type of cluster assessed, the MTCIs are coordinated by ECDC or EFSA or jointly by both agencies together with public health and/or food safety and veterinary experts from the involved European Union (EU) and European Economic Area (EEA) Member States.

ECDC collects human typing data through the European Surveillance System (TESSy) since 2013 [1]. Typing data from non-human isolates can now be submitted by the food and veterinary authorities of the EU/EEA Member States through the EFSA molecular typing data collection system. Furthermore, the joint ECDC-EFSA molecular typing database allows the comparison of the typing data collected by ECDC and EFSA.

First launched in March 2010, the Epidemic Intelligence Information System for food- and waterborne diseases and zoonoses (EPIS-FWD) has become an important tool for assessing on-going public health risks related to FWD events worldwide. Currently, 52 countries from five continents have access to the outbreak alerts in the EPIS-FWD [2].

Since its launch, 305 outbreak alerts have been assessed through the EPIS-FWD; 32 (10%) were from countries outside of the EU/EEA which underlines the global dimension of the system.

The Health Security Committee, a part of the European Commission and the officially nominated public health risk management authority in the EU/EEA, has access to the EPIS-FWD to ensure the link between risk assessment and risk management. The World Health Organisation (WHO), including the International Network of Food Safety Authorities (INFOSAN) managed jointly by the Food and Agriculture Organisation of the United Nations (FAO) and WHO, is invited to contribute to the discussions in the EPIS-FWD when international outbreaks involve non-EU/EEA countries.

Through this new version of EPIS-FWD, ECDC and EFSA are encouraging the sharing of data between sectors and aspire to strengthen the multi-sectorial collaboration at international and national levels.

E. coli O26, HUS and dairy

In their recent article in Eurosurveillance, Germinario et al. describe a community-wide outbreak of Shiga toxin 2-producing Escherichia coli (STEC) O26:H11 infections associated with haemolytic uraemic syndrome (HUS) and involving 20 children between 11 and 78 months of age in southern Italy during the summer 2013 [1]. The investigation identified an association between STEC infection and consumption of dairy products from two local milk-processing establishments. We underline striking similarities to a recent multi-country STEC O26 outbreak in Romania and Italy and discuss the challenges that STEC infections and their surveillance pose at the European level.

e-coli-colbertIn March 2016, Peron et al. published, also in Eurosurveillance, early findings of the investigation of a community-wide STEC infection outbreak in southern Romania [2]. As at 29 February 2016, 15 HUS cases with onset of symptoms after 24 January 2016, all but one in children less than two years of age, had been identified, three of whom had died. Aetiological confirmation was retrospectively performed through serological diagnosis and six cases were confirmed with STEC O26 infection. Shortly after this publication, and following the identification of the first epidemiologically-linked case in central Italy, the European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA) published a joint Rapid Outbreak Assessment [3]. The Italian and Romanian epidemiological, microbiological and environmental investigations implicated products from a milk-processing establishment in southern Romania as a possible source of infection. The dairy plant exported milk products to at least four European Union (EU) countries. The plant was closed in March 2016 and the implicated food products recalled or withdrawn from the retail market.

Pulsed Field Gel Electrophoresis (PFGE) and whole genome sequencing (WGS) analyses did not establish a microbiological link between the Italian (2013) and the Romanian/Italian (2016) outbreaks (personal communication, Stefano Morabito, October 2016). However, the epidemiological similarities between the two community-wide outbreaks associated with HUS and STEC O26 infections, mostly affecting young children and implicating dairy products, are notable. While raw milk and unpasteurised dairy products are well known potential sources of STEC infection, milk products, as highlighted by Germinaro et al. [1], have been rarely implicated in community-wide STEC outbreaks in the past, emphasising an emerging risk of STEC O26 infection associated with milk products.

Reporting of STEC O26 infections has been steadily increasing in the EU since 2007, partly due to improved diagnostics of non-O157 sero-pathotypes [4]. The attention to non-O157 STEC sero-pathotypes rose considerably after the severe STEC O104 outbreak that took place in Germany and France in 2011 during which almost 4,000 cases and more than 50 deaths were reported [5]. In light of the recently published outbreaks related to dairy products and the simultaneous increased reporting of isolations of STEC O26 from milk and milk products in the EU/European Economic Area (EEA) [6], strengthening STEC surveillance in humans and food and enhancing HUS surveillance in children less than five years of age is warranted. Paediatric nephrologists should be sensitised to this effect

Be good at whatever you do: especially preparing food that makes people barf

Amy is away in Adelaide, doing what she is good at: French professoring.

larry-molsonWalking Sorenne to her last day of grade 2 this morning – summer in Australia – she asked me, what should I be when I grow up?

I said, I’ll let you know when I grow up.

We chatted back and forth, and then came the advice I had heard from my father and uncle: I don’t care what you do, but be really good at it.

I told Sorenne mom was really good at the French professoring thing, I was really good at the food safety thing, and she could decide what to be really good at.

My uncle Larry is in this pic (below, left); he worked the railroads and played hockey in the Huntsville-north-of-Toronto-but not-too far-north leagues; settled in Barrie and when I was a kid, about 1970, on those every other weekends we would visit from Brantford, would go watch what I thought were giants of the neighborhood on a sunday morning pick-up, and then watch them drink beers.

I keep this amongst my hockey memorabilia.

In his later years, uncle Larry drove a truck for Molsons brewery out of Barrie.

That plant is long defunct, I don’t know who owns Molsons, but I do know that in 1982, uncle Larry would be delivering a load to Guelph and would honk at me as he passed by.

He also gave me a ridiculous supply of beer returned from the stores.

Larry and aunt  Shirley also let me and my high school girlfriend, Sue, sleep in the same bed.

That was awesome.

larry-hockey-16So when the free beer allotment for Labatt retirees — which was part of the workers’ pension benefit package for more than five decades — will soon go flat, I thought of Larry.

Labatt has announced the long-standing perk will be phased out by Jan.1, 2019 because it’s too expensive. But workers call the cut petty when compared to the company’s ballooning revenues.

Labatt said the allotment for existing retirees would be cut in half in 2018 and cut off completely in 2019.

“I just think it’s nickel-and-diming of our retirees that put in a lot of work for many, many years,” said local union president Jim Stirr. “In the cost of doing business, it’s such a small, small thing.”

Labatt, a formerly Canadian beermaker, is now owned by Belgium-based global super-producer Anheuser-Busch InBev. That’s a publicly traded company that owns more than 400 beer brands worldwide and reported $55 billion in revenue in 2015 alone.

“The reason for the change relates to the rising overall cost of maintaining a full benefits package, including health care coverage for retirees,” Labatt vice-president Lindsay King wrote in a letter to employees dated Oct. 28.

As in hockey, as in life, Some talk, some do, some play hockey.

Know thy water: If it’s dry, I’m gonna water rather than lose a crop

Foodborne disease outbreaks associated with fresh produce irrigated with contaminated water are a constant threat to consumer health. In this study, the impact of irrigation water on product safety from different food production systems (commercial to small-scale faming and homestead gardens) was assessed.

drip-irrigation-carrots-jun-16Hygiene indicators (total coliforms, Escherichia coli), and selected foodborne pathogens (Salmonella spp., Listeria monocytogenes, and Escherichia coli O157:H7) of water and leafy green vegetables were analyzed. Microbiological parameters of all irrigation water (except borehole) exceeded maximum limits set by the Department of Water Affairs for safe irrigation water. Microbial parameters for leafy greens ranged from 2.94 to 4.31 log CFU/g (aerobic plate counts) and 1 to 5.27 log MPN/100g (total coliforms and E. coli). Salmonella and E. coli O157:H7 were not detected in all samples tested but L. monocytogenes was present in irrigation water (commercial and small-scale farm, and homestead gardens).

This study highlights the potential riskiness of using polluted water for crop production in different agricultural settings.

Not: How to talk food safety with customers

Talk with, not to, people.

not-waynes-worldAnd if you’ve invested “tremendous resources in food safety” why not brag about it at retail, rather than in a lame journal no one will read.

FightBac sucks.

Food retailers have invested tremendous resources in food safety over the past two decades. Food safety is the foundation of food retailers’ relationships with their customers—consumers expect the food they purchase is safe. According to US Grocery Shopper Trends 2016 (FMI), nearly nine out of 10 shoppers have confidence in the safety of the food at the grocery store. Also, an increasing number of consumers are taking personal responsibility for food safety compared to just six years ago.

Food retailers are a credible and very accessible source of food safety information for consumers. For this reason, FMI has been a founding member and partner of the Partnership for Food Safety Education (PFSE) since its inception in 1997. PFSE is better known as the FightBac!® campaign which promotes  four core practices for food safety– Clean, Separate, Cook and Chill. The FightBac!® campaign provides food safety education to a variety of audiences through a network of health and food safety educators, called BAC Fighters. The retail food industry is an integral part of the BAC Fighter network.

 Because interacting with customers is essential for doing business, grocers are well positioned to put food safety information at shoppers’ fingertips. Over the years, PFSE has developed campaigns and toolkits for retailers to use in stores to help promote safe food handling at home.

Going public: FDA not liable for $15 million in damages sought by tomato grower for food safety warning error

I remember. I was in Quebec City with a pregnant Amy when all this went down. Doing hour-long iradio interviews where midnight callers asked about aliens and Salmonella.

tomato

Michael Booth of the National Law Journal reports the U.S. Food and Drug Administration cannot be held liable for financial damages suffered by farmers when it issues emergency, but erroneous, food safety warnings, the U.S. Court of Appeals for the Fourth Circuit has ruled.

In its Dec. 2 ruling, the Fourth Circuit refused to allow a South Carolina tomato farmer to seek more than $15 million in damages from the federal government under the Federal Tort Claims Act after the FDA issued a warning that an outbreak of Salmonella Saintpaul was caused by contaminated tomatoes, when it was later determined that the outbreak was caused by contaminated peppers imported from Mexico.

A South Carolina tomato farm, Seaside Farm on St. Helena Island, sued the federal government, claiming that the incorrect warnings issued by the FDA, beginning in May 2008 and later corrected, cost it $15,036,294 in revenue. The Fourth Circuit agreed with a trial court that the FDA was acting within its authority to issue emergency food safety warnings based on preliminary information in order to protect public health.

“We refuse to place FDA between a rock and a hard place,” wrote Judge J. Harvie Wilkinson for the panel, sitting in Richmond.

“One the one hand, if FDA issued a contamination warning that was even arguably overbroad, premature, or of anything less than perfect accuracy, injured companies would plague the agency with lawsuits,” he said.

“On the other hand, delay in issuing a contamination warning would lead to massive tort liability with respect to consumers who suffer serious or even fatal consequences that a timely warning might have averted,” Wilkinson said.

Judges Paul Niemeyer and Dennis Shedd joined in the Dec. 2 ruling.

The medical crisis arose on May 22, 2008, when the New Mexico Department of Health notified the Centers for Disease Control and Prevention (CDC) that a number of residents had been diagnosed as having Salmonella Saintpaul, a strain that causes fever, diarrhea, nausea and, if left untreated, death. Soon after, similar reports came in from Texas.

The CDC determined that a “strong statistical” analysis determined that the illnesses were caused by people eating raw tomatoes. By June 1 of that year, CDC was investigating 87 illnesses in nine states.

tomato-irradiationThe FDA then issued a warning to consumers in New Mexico and Texas. By June 6, 2008, however, reported cases grew to 145 incidents in 16 states. In New Jersey, three people were reported to have been diagnosed with the illness. On June 7, the FDA issued a blanket nationwide warning telling consumers that they should be wary of eating raw tomatoes. (New Jersey tomatoes were not implicated, since they do not ripen until later in the season.)

The warning listed a number of countries and states, including South Carolina, that were not included and were not implicated, but those states were not listed in media reports. Eventually, 1,220 people were diagnosed as having Salmonella Saintpaul.

Raw tomatoes were not the cause of the illnesses, however. The contamination was traced to imported jalapeño and serrano peppers imported from Mexico.

Seaside Farm, which had just harvested a large crop of tomatoes, sued in May 2011. The farm claimed the erroneous FDA warning about tomatoes cost it $15 million-plus damages in revenue. 

Barf on the subway: 7 left with breathing issues

Paramedics took seven people to the hospital when they complained of suddenly feeling lightheaded after a stranger vomited at a Harlem subway station early Tuesday, cops said.

santa-barf_sprout_raw_milk7-2The FDNY and police briefly evacuated the E. 125th St. station on the 4, 5 and 6 line about 9:15 a.m.

A police source said someone threw up and the other people became ill from the smell of the vomit.

The victims, who were on multiple trains, complained of having difficulty breathing. They were taken to Harlem Hospital for evaluation as a precaution, officials said.

Trains bypassed the station until about 9:50 a.m. while the NYPD’s Emergency Services Unit conducted air quality tests.

The tests came back negative for toxins, according to the MTA.

Listeria and leafy greens

Internalin A is an essential virulence gene involved in the uptake of the foodborne pathogen Listeria monocytogenes into host cells. It is intact in clinical strains and often truncated due to Premature Stop Codons (PMSCs) in isolates from processed foods and processing facilities. Less information is known about environmental isolates.

listeria4We sequenced the inlA alleles and did Multi Locus Variable Number Tandem Repeat Analysis (MLVA) on 112 L. monocytogenes isolates from a 3-year period from naturally contaminated watersheds near a leafy green growing area in Central California. The collection contained 14 serotype 1/2a, 12 serotype 1/2b, and 86 serotype 4b strains. Twenty-seven different inlA alleles were found. Twenty-three of the alleles are predicted to encode intact copies of InlA, while three contain PMSCs. Another allele has a 9-nucleotide deletion, previously described for a clinical strain, indicating that it is still functional. Intact inlA genes were found in 101 isolates, and 8 isolates contained the allele predicted to contain the 3-amino acid deletion. Both allele types were found throughout the 3-year sampling period. Three strains contained inlA alleles with PMSCs, and these were found only during the first 3 months of the study. SNP analysis of the intact alleles indicated clustering of alleles based on serotype and lineage with serotypes 1/2b and 4b (lineage I strains) clustering together, and serotype 1/2a (lineage II strains) clustering separately. The combination of serotype, MLVA types, and inlA allele types indicate that the 112 isolates reflect at least 49 different strains of L. monocytogenes. The finding that 90% of environmental L. monocytogenes isolates contain intact inlA alleles varies significantly from isolates found in processing plants.

This information is important to public health labs and growers as to the varieties of L. monocytogenes that could potentially contaminate fresh produce in the field by various means.

The majority of genotypes of the virulence gene inlA are intact among natural watershed isolates of Listeria monocytogenes from Central California Coast

Over 250 sick from Norovirus in Montana

 

The Department of Public Health and Human Services (DPHHS) announced Wednesday that in the last three months there have been 12 norovirus outbreaks in Montana that have sickened more than 250 people.

turkey-testicle-festivalThis is three times the number of outbreaks usually reported during this time of year.

Outbreaks have occurred in the counties of Cascade, Flathead, Rosebud, Sanders, Valley and Yellowstone.

“Most of these outbreaks occurred in nursing homes and assisted living facilities, putting our elderly population at risk,” said Dana Fejes of the DPHHS Communicable Disease Epidemiology Section. “Washing your hands thoroughly with soap and water often can protect you and others from norovirus.”
