Research – Campylobacteriosis – Annual Epidemiological Report for 2021

ECDC

The notification of campylobacteriosis is mandatory in 22 EU Member States, Iceland, Liechtenstein, and Norway. In five EU Member States (Belgium, France, Greece, Italy, and the Netherlands) notification is voluntary. The surveillance systems for campylobacteriosis have full national coverage in all EU Member States except four (France, Italy, the Netherlands, and Spain). The coverage of the surveillance system in 2021 is estimated to be 20% in France and 64% in the Netherlands. These proportions were used when calculating notification rates for these two EU Member States. No estimate of population coverage in Italy and Spain was provided, so notification rates were not calculated for these two countries. The drop in cases in Luxembourg in 2019 is a surveillance artefact caused by a change to non-culture-based methods (PCR) in private laboratories, resulting in a reduced number of isolates sent to the national reference laboratory. From 2020, laboratory confirmation with PCR is included in the notification system which, along with a new electronic laboratory notification system, is expected to result in an increase in Campylobacter notifications. Greece has reported data on laboratory-confirmed cases collected from public hospitals from 2018 onwards. For 2020 and 2021, Spain has not yet received data from all regions normally reporting and the case numbers are therefore lower than expected. All countries reported case-based data except Belgium, Bulgaria, and Greece, which report aggregated data. Both reporting formats were included to calculate numbers of cases, notification rates, disease trends, and age and gender distributions.

New Zealand – Don’t contaminate your plate this summer – be a Chicken Scene Investigator – Campylobacter

MPI

It would be a crime for your whānau and friends to come down with foodborne illness this festive season – so New Zealand Food Safety and the Chicken Scene Investigators have got your back.

“Each year, over our summer, there is a rise in cases of foodborne illness and hospitalisations,” says New Zealand Food Safety deputy director-general Vincent Arbuckle.

“The most commonly reported illness is campylobacteriosis – caused by Campylobacter bacteria – with our youngest and oldest having the highest rates of infection.

“There were 5,729 confirmed cases of campylobacteriosis in 2021, with 846 people needing hospital treatment, up from 718 in 2020. And 2022 looks set to follow a similar trajectory, with more than 5,300 cases nationally so far.

“The most common source of Campylobacter from food is raw or undercooked chicken.

“So, one big thing you can do this festive season to keep your whānau and friends healthy is to make sure you handle raw chicken safely. Cook it properly and use separate utensils and chopping boards, and, as with all food, don’t leave it out in the heat of the day, both before cooking and after you’ve finished eating.”

To help you with this, New Zealand Food Safety today launches a new food safety campaign. In a series of videos, our 2 Chicken Scene Investigators invite you to join them to spot the chicken-handling crime.

“Campylobacteriosis symptoms are nasty. They include diarrhoea, fever, headache, muscle aches, abdominal pain, and vomiting. It may also develop into more severe illness such as Guillain-Barré Syndrome, a disorder in which the body’s immune system attacks its nerves, sometimes resulting in permanent paralysis,” says Mr Arbuckle.

If you have symptoms, you can call Healthline for free anytime on 0800 61 11 16, or contact your doctor or practice nurse for advice.

“So, wherever you’re gathering – from BBQs to work do, beach parties to kai at the marae, Christmas lunch or potluck dinner – make sure you don’t contaminate your plate this summer.”

Te Whatu Ora medical officer of health Jay Harrower adds: “Every year thousands of people are diagnosed as being infected with Campylobacter, and for some it can be very serious. Across New Zealand Campylobacter cases are spiking once again this summer, but there are simple steps everyone can take to reduce the risk to them and their whānau.”

Chicken Scene Investigator tips to keep your whānau and friends safe:

  • Keep your raw chicken separate from ready-to-eat and fresh foods, using separate chopping boards, plates, and utensils. Alternatively, wash them properly with hot soapy water before using for other foods.
  • Don’t wash the chicken. Rinsing it will just spread the bacteria to other surfaces. Pat it dry with a paper towel instead, if needed.
  • Wash your hands in warm soapy water after handling raw chicken.
  • Make sure the chicken is fully cooked before serving – it can’t be pink and the juices should run clear. Or use a meat thermometer, if you have one, to ensure the chicken is steaming hot (over 75°C) all the way through.
  • Use a different plate for raw and cooked chicken.
  • If in doubt, clean surfaces and utensils some more, cook your chicken some more.

England – Differential impact of the COVID-19 pandemic on laboratory reporting of Norovirus and Campylobacter in England: A modelling approach

PLOS One

CDC Campy

The COVID-19 pandemic has impacted surveillance activities for multiple pathogens. Since March 2020, there was a decline in the number of reports of norovirus and Campylobacter recorded by England’s national laboratory surveillance system. The aim is to estimate and compare the impact of the COVID-19 pandemic on norovirus and Campylobacter surveillance data in England.

EFSA – Campylobacter Dashboard

EFSA

The EFSA dashboard on Campylobacter is a graphical user interface for searching and querying the large amount of data collected each year by EFSA from EU Member States and other reporting countries based on Zoonoses Directive 2003/99/EC. The Campylobacter dashboard shows summary statistics for the monitoring results of the pathogen with regard to major food categories, Campylobacter-positive official samples exceeding the Process Hygiene Criterion limit of 1,000 CFU/g for chilled broiler carcases and the occurrence of Campylobacter in major food categories. The Campylobacter data and related statistics can be displayed interactively using charts, graphs and maps in the online EFSA dashboard. The main statistics can also be viewed and downloaded in tabular format. Detailed information on the use and features of the Campylobacter dashboard can be found in the present user guide that can also be downloaded from the online tool.

Research – Zoonotic diseases and foodborne outbreaks on the rise, but still below pre-pandemic levels

EFSA

In 2021 there was an overall increase in reported cases of zoonotic diseases and foodborne outbreaks compared to the previous year, but levels are still well below those of the pre-pandemic years, reveals the latest annual EU One Health zoonosis report released by EFSA and ECDC.

The general drop compared to pre-pandemic years in reported cases and outbreaks is probably linked to COVID-19 control measures, which were still in place in 2021. Among the few exceptions are the number of cases for yersiniosis and those of foodborne listeriosis outbreaks, which exceeded pre-pandemic levels.

Most foodborne outbreaks (773) were caused by Salmonella, which accounted for 19.3% of the total. Foodborne outbreaks differ from overall reported disease cases in that they are events in which at least two people contract the same illness from the same contaminated food. The most common sources of salmonellosis outbreaks were eggs, egg products, and “mixed foods”, which are meals composed of various ingredients.

The number of outbreaks caused by Listeria monocytogenes (23) was the highest ever reported. This might be linked to the increased use of whole genome sequencing techniques, which allow scientists to better detect and define outbreaks.

The report also covers overall reported zoonotic disease cases, which are not necessarily linked to outbreaks. Campylobacteriosis remains the most frequently reported zoonosis, with the number of reported cases increasing to 127,840 compared to 120,946 in 2020. Meat from chicken and turkeys was the most common source. Salmonellosis was the second most reported zoonotic disease, affecting 60,050 people compared to 52,702 in 2020. The next commonly reported diseases were yersiniosis (6,789 cases), infections caused by Shigatoxin-producing E. coli (6,084 cases), and listeriosis (2,183 cases).

The report also includes data on Mycobacterium bovis/caprae,BrucellaTrichinellaEchinococcus, Toxoplasma gondii, rabies, Q fever, West Nile virus infections and tularaemia.

Research – One Health Campylobacter Risk Model Could Improve Outbreak Surveillance

Food Safety.Com

Researchers have built a new risk model for possible human Campylobacter outbreaks that leverages data on weather patterns and the presence of Campylobacter on broiler farms. The developers of the model hope to disseminate the information it produces through a website that can generate warnings when appropriate.

The model follows a “One Health” approach, in that data from the animal, human, and environmental sectors were combined to predict human gastrointestinal illness (GI) outbreaks.

Research – Molecular Epidemiological Evidence Implicates Cattle as a Primary Reservoir of Campylobacter jejuni Infecting People via Contaminated Chickens

MDPI

CDC Campy

The study aimed to determine the relative contribution of cattle to the burden of illness in a model agroecosystem with high rates of human campylobacteriosis (≥ 115 cases/100 K), and high densities of cattle, including large numbers of cattle housed in confined feeding operations (i.e., in southwestern Alberta, Canada).
To accomplish this, a large-scale molecular epidemiological analysis of Campylobacter jejuni circulating within the study location was completed. In excess of 8000 isolates of C. jejuni from people (n = 2548 isolates), chickens (n = 1849 isolates), cattle (n = 2921 isolates), and water (n = 771 isolates) were subtyped.
In contrast to previous studies, the source attribution estimates of clinical cases attributable to cattle vastly exceeded those attributed to chicken (i.e., three- to six-fold). Moreover, cattle were often colonized by C. jejuni (51%) and shed the bacterium in their feces.
A large proportion of study isolates were found in subtypes primarily associated with cattle (46%), including subtypes infecting people and those associated with chickens (19%). The implication of cattle as a primary amplifying reservoir of C. jejuni subtypes in circulation in the study location is supported by the strong cattle association with subtypes that were found in chickens and in people, a lack of evidence indicating the foodborne transmission of C. jejuni from beef and dairy, and the large number of cattle and the substantial quantities of untreated manure containing C. jejuni cells.
Importantly, the evidence implicated cattle as a source of C. jejuni infecting people through a transmission pathway from cattle to people via the consumption of chicken. This has implications for reducing the burden of campylobacteriosis in the study location and elsewhere. View Full-Text

Research team work on a rapid test for foodborne pathogens in poultry

Poultry World

A research team at Michigan State University will use a grant from the USDA to develop a rapid biosensor test for foodborne pathogens. The rapid test will be used onsite at poultry farms and processing facilities to inspect large samples for Salmonella and Campylobacter.

The US$769,000 grant was received from the US Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA), and Professor Evangelyn Alocilja, who is in the MSU Department of Biosystems and Agricultural Engineering, is leading the project. She is an expert in her field and in rapid biosensing diagnostics for infectious and antimicrobial-resistant diseases, having developed such tests for tuberculosis, dengue and Covid-19.

Poultry products are one of the most common sources of infection

Alocilja says that studies have shown poultry products are one of the most common sources of infection due to bacterial contamination from farm production practices and processing equipment. In the US, the economic burden of Salmonella and Campylobacter from all sources exceeded US$6 billion in 2018, according to the USDA Economic Research Service.
