Research – Outbreak of Clostridium perfringens food poisoning linked to leeks in cheese sauce: an unusual source

Cambridge Uni Press

Between 11–13 December 2018, local public health authorities in the West Midlands, England were alerted to 34 reports of diarrhoea with abdominal cramps. Symptom onset was ~10 h after diners ate Christmas meals at a restaurant between 7–9 December 2018. A retrospective case-control study, environmental and microbiological investigations were undertaken to determine the source and control the outbreak. An analytical study was undertaken with odds ratios (OR) and 95% confidence intervals (CI). Forty persons were recruited to the analytical study (28/40 cases). Multivariable analysis found that leeks in cheese sauce was the only item associated with illness (aOR 51.1; 95% CI 4.13–2492.1). Environmental investigations identified significant lapses in food safety, including lapses in temperature control during cooking and hot holding, likely cross-contamination between raw and cooked foods and the reuse of leftover cheese sauce for the next day’s service. No food samples were taken during the exposure period. Two faecal samples were positive for Clostridium perfringens with one confirming the enterotoxigenic gene. Cheese sauce is an unusual vehicle for the organism and the first time this has been reported in England.

17 March 2020

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.

USA – Outbreak Investigation of E. coli O103: Clover Sprouts (February 2020)

FDA

Recommendation

FDA is recommending that consumers not eat the following sprout-containing items from Chicago Indoor Garden, Chicago, IL, with Best By dates between December 1, 2019 and March 12, 2020: red clover (with and without non-GMO labels), sprout salad, mixed greens, and spring salad. Labels of the products are below.

(PDF: 849 KB)

The FDA’s analysis of a sample of this firm’s product identified the presence of E. coli O103. Whole Genome Sequencing of this bacteria showed that it matches the outbreak strain.

Generally, it is recommended that children, the elderly, pregnant women, and persons with weakened immune systems should avoid eating raw sprouts of any kind.

Background

FDA, along with CDC and state and local partners, are investigating an outbreak of 14 illnesses caused by E. coli O103 in Iowa, Illinois, Missouri, Texas and Utah likely linked to clover sprouts.

As the outbreak investigation progresses, the FDA will continue in its traceback investigation to determine where implicated sprouts have been distributed and will continue monitoring for additional illnesses associated with this outbreak.

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
