Germany – Survey finds low Campylobacter knowledge in Germany

Food Safety News 

Consumer knowledge in Germany of Toxoplasma was better than that of Campylobacter, according to a recent report on a study.

Researchers surveyed 1,008 consumers in August 2017 in Germany via an online panel on Campylobacter, Salmonella and Toxoplasma and transmissibility via meat. The questionnaire had 43 questions in five sections.

Consumers were most informed about Salmonella and general knowledge of Toxoplasma is better than Campylobacter. Campylobacter, despite its high incidence in Germany, was largely unknown to consumers.

With almost 70,000 confirmed cases in 2017, Campylobacter is the main bacterial infection causing diarrhoeal disease reportable in Germany. Second was salmonellosis with 14,269 confirmed infections. Only seven cases of congenital human toxoplasmosis were confirmed in 2017.

A previous survey by the German Federal Institute for Risk Assessment (BfR) found only 28 percent of people had heard of Campylobacter.

Research – Researchers turn to air sampling to detect Campylobacter in chicken flocks

Food Safety News

 

A project led by the National Food Institute, Technical University of Denmark, has developed a test method to improve the likelihood of identifying Campylobacter-positive chicken flocks.

Being able to identify Campylobacter-positive flocks before they arrive at the slaughterhouse allows them to be slaughtered after the negative flocks to avoid cross-contamination along the production line.

The method was worked on in the EU project, AIR-SAMPLE, which began in January 2018 and runs until June 2020. Other partners are the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise “Giuseppe Caporale” in Italy, Veterinary Research Institute in the Czech Republic, National Veterinary Research Institute in Poland and Norwegian Veterinary Institute.

The aim was to develop and validate air sampling as a low-cost and multi-purpose alternative to fecal droppings or boot swabs for surveillance, monitoring and eradication of Campylobacter in confined and biosecured broiler production operations.

Article: 54/1104

Food Standards Scotland (FSS) has published new research on Campylobacter, the most common cause of bacterial food poisoning in Scotland, which provides evidence concerning those at greater risk of infection and severe illness, and the estimated healthcare cost of infection. Conducted between 2013 and 2019, this research was undertaken by Health Protection Scotland (HPS) and the University of Aberdeen, on behalf of FSS.

The research confirmed that, while a higher number of cases are reported in more affluent areas of Scotland, those living in the most deprived areas are at an increased risk of developing serious illness and being hospitalised.

The results showed that overall, around 14% of Campylobacter cases lead to hospitalisation, with hospital admissions more likely to have one or more of the following risk factors:

  • being 65 years or older
  • having an underlying medical condition
  • being prescribed with proton pump inhibitor to reduce stomach acid production in the 90 days prior to infection

The findings from this research have enabled public health authorities to estimate that, with approximately 6,000 cases reported per year, Scotland’s total annual healthcare cost for Campylobacter infections is approximately three million pounds.

Research – Prevalence of Salmonella spp. and Campylobacter spp. in alternative and conventionally produced chicken in the United States: A systematic review and meta-analysis

JFP

The burden of foodborne illness linked to the consumption of contaminated broiler meat is high in the United States. With the increase in popularity of alternative poultry rearing and production systems, it is important to identify the difference in food safety risks presented by alternative systems when compared to conventional methods. While many studies have been conducted surveying foodborne pathogen prevalence along the broiler supply chain, a systematic overview of all of the available results is lacking. In the current study, a systematic review and meta-analysis was conducted to quantify the differences in Salmonella spp. and Campylobacter spp. prevalence in farming environment, rehang, prechill, postchill, and retail samples between conventional and alternative production systems. A systematic search of Web of Science and PubMed databases was conducted to identify eligible studies. Studies were then evaluated by inclusion criteria, and included studies were qualitatively and quantitatively analyzed. In total, 137 trials from 72 studies were used in the final meta-analysis. Meta-analysis models were individually constructed for subgroups that were determined by sample type, pathogen, and production type. All subgroups possessed high amounts of heterogeneity (I 2 > 75%). For environmental sample subgroups, Campylobacter prevalence was estimated to be 15.8 and 52.8% for conventional and alternative samples, respectively. Similar prevalence estimates for both production types were observed for Salmonella environmental samples and all retail samples. For conventional samples, Campylobacter and Salmonella prevalence was highest in prechill samples, followed by rehang and postchill samples, respectively. The presented results will be of use in future quantitative microbial risk assessments to characterize the differences in foodborne illness risks presented by different broiler production systems.

UK – New research shows societal burden of foodborne illness in the UK

FSA

The FSA Board has welcomed a report which presents new comprehensive estimates of the societal burden caused by foodborne illnesses in the UK.

The outcome of an extensive programme of work conducted over a five-year period was scrutinised by Members at the FSA Board Meeting, and provides a more in depth understanding of the wider impacts of foodborne diseases such as norovirus, campylobacter and listeria.

For the first time, the study also incorporates estimates based on the impacts of foodborne illness cases where a specific pathogen is not identified, often as a result of people not seeking medical attention.

The new model which produced the estimates follows an established process used in the UK and internationally to assess the financial impacts and the ‘human costs’ such as pain grief and suffering and changes to quality and length of life.

Estimates for these ‘human costs’ were developed in part by surveying more than 4,000 people to produce monetised values to measure the impact of different foodborne pathogens.

This will allow for these intangible human impacts to be considered alongside financial impacts when decisions relating to foodborne illnesses are made.

The model shows that for 2018:

  • the burden arising from the 13 main foodborne pathogens is around £3bn. Norovirus imposes the greatest burden at an estimated annual cost of £1.68bn followed by Campylobacter spp. (£0.71bn) and Salmonella spp. (non-typhoidal) (£0.21bn).
  • foodborne illness cases where a pathogen was not identified causes an estimated societal burden of around £6bn.
  • Taken together, the two estimates lead to a headline figure of approximately £9bn, as the annual cost burden of foodborne illness in the UK in 2018.
  • cases of Campylobacter, which are more common but generally less severe, impose a burden of £2,380 each while Listeria, the least common of the 13 measured, has a burden equivalent to £230,748 due to a higher proportion of fatalities, resulting in a higher ‘human cost’.

 

The Board welcomed the work and the report’s findings which provides the FSA with a more robust and comprehensive awareness of the impact of all foodborne illnesses and an additional tool to direct future decisions on prevention.

Heather Hancock, Chair of The Food Standards Agency said:

“I welcome this vital new research.  Being able to put a cost on the personal, social and economic burden when someone becomes ill as a result of food, represents a milestone for the FSA.

“We will use this new analysis of the cost of illness, and how it varies between different germs, to help set our priorities for tackling foodborne illness and to focus the FSA’s expertise, money and influence.”

 

Professor Rick Mumford, Head of Science Evidence and Research at the Food Standards Agency said:

“For the first time this model gives the FSA and other partners a much more detailed picture of how foodborne illnesses can impact society.

“We have designed it from the ground up to measure the impacts of specific pathogens as well as for the first time providing an estimate of the majority of cases where no pathogen is attributed.

“As a result, we are now equipped with robust, quantitative evidence on the impact of foodborne disease which significantly strengthens our decision-making ability.”

 

Richard Smith, Deputy Pro Vice Chancellor and Professor of Health Economics at the University of Exeter said:

“Providing an understanding of the impact of foodborne disease on individuals and wider society is a critical building block to understanding where and how to best deal with it.

“The FSA has a rich history of developing such analyses, and this latest work builds on that with significant revisions and updates to provide the most robust values yet of the societal impact of foodborne disease.

“This provides a robust, powerful and flexible tool to assist FSA in determining its priorities for tackling foodborne disease, which remains a serious challenge for our society.”

FSA economists worked with academics from leading UK universities to develop the Cost of Illness (COI) model to identify and measure all the costs of a particular disease.

The model is loosely based on the Health and Safety Executive (HSE)’s Cost to Britain model (Opens in a new window)which estimates the annual cost of workplace fatalities, self-reported injuries and ill health at £15bn.

This new model was quality assured internally and externally by independent experts and represents a significant improvement from the previous, much simpler model used to estimate the burden of foodborne illness. Further work is currently ongoing to apply these methodologies to other areas, including food allergy and hypersensitivity.

Other notes

Comparisons to previous estimates is not possible as this is the first time that the FSA have estimated the total burden of foodborne illness.

This estimate is therefore inevitably greater than the estimates for identifiable cases alone for the following reasons:

  • this is the first time we are measuring cases where no specific pathogen is attributed, which account for 60% of cases
  • the estimated number of illnesses cases attributed to foodborne illnesses has increased from 1 million to 2.4 million as announced last month
  • The new model uses a different methodology to calculate the non-financial ‘human costs’, which account for almost 80% of the overall burden

New Zealand – New Zealand Food Safety sets significant new goal to reduce foodborne Campylobacter by 20 per cent by 2025

MPI

Deputy director-general for New Zealand Food Safety Bryan Wilson announced today a new goal to significantly reduce foodborne Campylobacter poisoning by 20% by 2025.

Campylobacter is the most common cause of notifiable foodborne illness in New Zealand. Symptoms can include stomach cramps, nausea, fever and diarrhoea, lasting for about a week.

“Contributing factors are Kiwis’ ever-increasing level of consumption of fresh chicken meat and the way we handle, prepare and cook poultry meat in New Zealand.

“Working with the poultry industry, New Zealand Food Safety’s risk management strategy has achieved more than a 50% reduction in foodborne cases since 2006. This is a substantial reduction and one that we could not have achieved without partnership and support from industry. But, the rate of gastrointestinal illness caused by this bug remains high,” says Mr Wilson.

“New Zealand Food Safety and industry continue to work collaboratively to reduce Campylobacter rates in the country with an updated strategy and action plan that includes enhanced consumer education, better hygiene through the poultry processing and food distribution chain, and improved measures at the poultry farm level,” says Mr Wilson.

New Zealand Food Safety commissioned the study to add a high level of scientific rigour to efforts to reduce foodborne illnesses, and the findings of the study Source assigned campylobacteriosis in New Zealand were also released today.

The results from the study found more than 80% of human foodborne cases are likely due to the consumption of poultry meat.

“The intensive 12-month study included interviews with 666 individuals who’d been infected with the bug.

“As well as identifying the sources of Campylobacter illnesses in humans, the study identified several factors that may increase the likelihood of an individual contracting the disease.

“We’ll continue our work with industry to drive down the level of Campylobacter in poultry by understanding where the bacteria enter the food chain and where cross-contamination is likely happening.

“It’s important consumers know how to prevent Campylobacter in the home by continuing to follow the advice on the New Zealand Food Safety web page Clean, Cook, Chill.

“Cooking chicken properly until the juices run clear and having good hygiene practises at home to prevent cross-contamination will minimise your risk to Campylobacter and other foodborne illnesses,” says Mr Wilson.

Researchers have called for increased awareness to reduce the risk of Campylobacter outbreaks linked to incorrectly cooked chicken liver dishes.

Communication from food safety and public health authorities may be required. Any strategy should ensure the risk profile of poultry liver-containing dishes is raised and availability of evidence-based preventative strategies for food preparation promoted, according to the study published in the journal Epidemiology and Infection.

There were 19 people who got campylobacteriosis linked to an outbreak in England 2016; seven confirmed and 12 probable cases. Chicken liver pâté was most strongly associated with illness. Three cases reported an incubation period of less than 24 hours, consistent with other outbreaks of campylobacteriosis associated with poultry liver.

Diversorium Ltd., the company which owned and operated the Downe Arms, a hotel in Wykeham near Scarborough, was fined £8,000 ($10,300) in November 2017 for two food hygiene related offences related to the outbreak.

Research -Persistent contamination of Salmonella, Campylobacter, Escherichia coli, and Staphylococcus aureus at a broiler farm in New Zealand

Canadian Journal of Microbiology

Intensive poultry production due to public demand raises the risk of contamination, creating potential foodborne hazards to consumers. The prevalence and microbial load of the pathogens CampylobacterSalmonellaStaphylococcus aureus, and Escherichia coli was determined by standard methods at the farm level. After disinfection, swab samples collected from wall crevices, drinkers, and vents were heavily contaminated, as accumulated organic matter and dust likely protected the pathogens from the disinfectants used. The annex floor also showed high microbial concentrations, suggesting the introduction of pathogens from external environments, highlighting the importance of erecting hygiene barriers at the entrance of the main shed. Therefore, pathogen control measures and proper application of disinfectants are recommended as intervention strategies. Additionally, quantitative polymerase chain reaction (qPCR) was evaluated as a quantification tool. qPCR showed limitations with samples containing low microbial counts because of the low detection limit of the method. Thus, bacterial pre-enrichment of test samples may be necessary to improve the detection of pathogens by qPCR.
