USA – Chicken and Eggs Top List of Causes for Foodborne Outbreaks

Healthline

 

Chicken, eggs, and produce are most likely to carry bacteria responsible for the vast majority of foodborne illness in the United States.

The bacteria most likely to make you sick year after year: Campylobacter and Salmonella. Less common pathogens also include ShigellaCyclospora, and Listeria.

Foodborne illness is still a major health problem in the United States, according to a report released last week from the Centers for Disease Control and Prevention (CDC).

The agency identified more than 25,000 foodborne infections through various surveillance sites in 2018. Nearly 6,000 of those cases resulted in hospitalizations, and 120 people died as a result of foodborne illness.

The report is part of annual surveillance by the CDC that tracks the pathogens responsible for foodborne illness.

Guam – Shigellosis outbreak in Guam: An update

Outbreak News Today

Shigellosis outbreak in Guam: An update

In a follow-up on the outbreak of Shigella infections in Guam, The Department of Public Health and Social Services (DPHSS) reports the outbreak continues to grow.


In 2019, in only four months, Guam has already reached one-half of the total number of cases from all of last year. In 2018, a total of 29 cases of Shigellosis were reported (with 23 cases or 79% confirmed).   So far in 2019, a total of 15 cases have been reported (with 53% confirmed).

Approximately two-thirds (66.6%) of the 2019 cases involved children who have been taken to the emergency rooms for treatment with some being hospitalized.

Five of the 15 cases are children less than five years old; another five cases are among children less than 15 years old and the other five are adults.

The public is asked to be vigilant about hygiene and sanitation, especially for people living in crowded housing situations or housing where there is a lack of indoor plumbing and where contact with faecal matter is possible.

Research – Estimate of the annual burden of foodborne illness in nondeployed active duty US Army Service Members: five major pathogens, 2010–2015

Cambridge.org

In this study, we estimate the burden of foodborne illness (FBI) caused by five major pathogens among nondeployed US Army service members. The US Army is a unique population that is globally distributed, has its own food procurement system and a food protection system dedicated to the prevention of both unintentional and intentional contamination of food. To our knowledge, the burden of FBI caused by specific pathogens among the US Army population has not been determined. We used data from a 2015 US Army population survey, a 2015 US Army laboratory survey and data from FoodNet to create inputs for two model structures. Model type 1 scaled up case counts of Campylobacter jejuniShigella spp., Salmonella enterica non-typhoidal and STEC non-O157 ascertained from the Disease Reporting System internet database from 2010 to 2015. Model type 2 scaled down cases of self-reported acute gastrointestinal illness (AGI) to estimate the annual burden of Norovirus illness. We estimate that these five pathogens caused 45 600 (5%–95% range, 30 300–64 000) annual illnesses among nondeployed active duty US Army Service members. Of these pathogens, Norovirus, Campylobacter jejuni and Salmonella enterica non-typhoidal were responsible for the most illness. There is a tremendous burden of AGI and FBI caused by five major pathogens among US Army Soldiers, which can have a tremendous impact on readiness of the force. The US Army has a robust food protection program in place, but without a specific active FBI surveillance system across the Department of Defence, we will never have the ability to measure the effectiveness of modern, targeted, interventions aimed at the reduction of specific foodborne pathogens.

UK – Scotland – Annual summary of Salmonella infections, 2018

HPS Scotland 

During 2018, the Scottish SalmonellaShigella and Clostridium difficile Reference Laboratory (SSSCDRL) reported 751 cases of human non-typhoidal Salmonella to Health Protection Scotland. This represented a 10% decrease on the 840 cases reported in 2017, and the 839 cases reported in 2016.

Research – Anti-adhesion of probiotic Enterococcus faecium WEFA23 against five pathogens and the beneficial effect of its S-layer proteins against Listeria monocytogenes

Canadian Journal of Microbiology

Enterococcus faecium WEFA23 is a potential probiotic strain isolated from Chinese infant feces. In this study, the antagonistic activity of Efaecium WEFA23 on adhesion to pathogens was investigated. Enterococcus faecium WEFA23 was able to compete, exclude, and displace the adhesion of Escherichia coli O157:H7, Salmonella Typhimurium ATCC 13311, Listeria monocytogenes CMCC54007, Staphylococcus aureus CMCC26003, and Shigella sonnei ATCC 25931 to Caco-2 cells. Among them, Lmonocytogenes achieved the strongest inhibition rate in both competition and displacement assays. Those anti-adhesion capacities were related to the bacterial physicochemical properties (hydrophobicity, auto-aggregation, and co-aggregation) of the bacterial surface. For L. monocytogenes, the anti-adhesion capacity was affected by the heat treatment, cell density, and growth phase of E. faecium WEFA23; 108 colony-forming units of viable cells per millilitre at the stationary phase exhibited the strongest anti-adhesion activity. In addition, removal of S-layer proteins of E. faecium WEFA23 by treatment with 5 mol/L LiCl significantly decreased its adhesion capacity, and those S-layer proteins were able to compete, displace, and exclude L. monocytogenes at different levels. Both cells and S-layer proteins of E. faecium WEFA23 significantly reduced the apoptosis of Caco-2 cells induced by L. monocytogenes, which was mediated by caspase-3 activation. This study might be helpful in understanding the anti-adhesion mechanism of probiotics against pathogens.

UK – Bride ‘left unable to walk after contracting food poisoning’ on 5-star Egypt honeymoon

Cristina Calafateanu, 24, now needs a walking frame to get about after a gastric bug she caught after staying at the Baron Palace Sahl Hasheesh in Hurghada, booked through Thomas Cook, caused her to develop arthritis.

Cristina Calafateanu says she and husband Liviu suffered diarrhoea and severe stomach cramps just three days into their week-long stay in Egypt.

When she returned to the UK she was diagnosed with bacterial infection Shigella – before medics told her the illness had triggered a form of arthritis.

Research -Vermont officials investigate Shigella outbreak at Wake Robin Community

Outbreak News Shigella - kswfoodworld

Vermont health officials are investigating a shigellosis outbreak at the Wake Robin retirement community in Shelburne.

To date, 67 cases have been reported with one third testing positive for the bacterium.

Wake Robin is collecting data to pinpoint the source of the outbreak, and has closed the group dining hall until the outbreak has subsided.

Clinical manifestations of shigellosis range from watery or loose stools with minimal symptoms to more severe illness including high fever, abdominal cramps or tenderness, tenesmus, and mucoid stools with or without blood. Symptoms usually resolve in five to seven days but sometimes last for four or more weeks. Asymptomatic infection is possible.

Research – Traveler’s diarrhoea: Researchers develop 3-in-1 vaccine

Outbreak News Today 

 

A first-ever vaccine designed to deliver a one-two-three punch against the main causes of traveller’s diarrhea worldwide may result from new research published by a University of Guelph chemist.

Prof. Mario Monteiro says his novel three-in-one approach to developing a new vaccine could also save lives in developing countries, where it’s estimated that these three common pathogens kill more than 100,000 children under age five each year.

His research was recently published in the journal Vaccine.

The paper discusses Monteiro’s so-called conjugate vaccine that yokes together proteins from pathogenic E. coli with sugars from Shigella and Campylobacter jejuni. All three bugs are major causes of bacterial diarrhea globally.

Poland – Shigella sonnei outbreak linked to Rainbow Gathering

European health officials are reporting a Shigella sonnei outbreak among participants of a Rainbow Gathering in the south-east of Poland.

Between 5 and 10 August 2018, 45 participants presented with gastroenteritis symptoms, 14 of these tested positive for Shigella sonnei. The event took place between 13 July and 11 August and so it is likely that most participants, which come from many countries within the EU, have now left the area.

Last year, a typhoid outbreak was linked to the European Rainbow gathering that took place in Tramonti di Sopra, Friuli-Venezia Giulia region, Italy.
