USA – Señor Moose restaurant in Seattle is again open after Hepatitis A scare

Food Safety News

Since April 15, Public Health for Seattle and King County, WA, has learned of three people from three separate meal parties becoming ill with jaundice, abdominal pain, nausea, vomiting, fever, and fatigue after consuming food from the Señor Moose restaurant between Feb. 24 and 26.

There is no indication that any current employees of the restaurant have had illnesses consistent with hepatitis A symptoms. Public Health is also contacting former employees to find out if any of them have been ill.

The restaurant, at 5242 Leary Ave. NW, in Seattle, has a current food safety rating of “Good.”

This outbreak, which involves the hospitalization of one person, is occurring while the Seattle-King County area is experiencing an outbreak of hepatitis A, mostly among the homeless. Washington State last July declared a statewide hepatitis A outbreak among people who are homeless or using drugs.

China – Norovirus outbreak in China linked to delivered food

Food Safety News Norovirus Food Safety kswfoodworld

Norovirus was behind a foodborne outbreak in 2018 caused by eating take-out food in China, according to a study.

The outbreak involved 157 probable cases and 20 people had laboratory-confirmed norovirus infections in two weeks in March 2018.

Food delivery services have become common in China in recent years but the hygienic condition of delivered food is not easy to control. Contamination can occur at any stage, from preparation to distribution, and food handlers must play an important role, said researchers.

The outbreak was managed by restrictions on off-campus dining and implementation of disinfection and case isolation measures.

USA – Norovirus outbreak reported on Royal Caribbean’s Grandeur of the Seas

Outbreak News Today norovirus-1080x655

Federal health officials report investigating a norovirus outbreak onboard Royal Caribbean International vessel, Grandeur of the Seas.

The outbreak on the March 7–March 19, 2020 voyage has sickened 83 passengers and six crew members, who developed symptoms of vomiting and diarrhea.

Specimens have been collected, tested onboard, and found to be positive for norovirus. The specimens will be sent to CDC for genome sequencing.

USA – Blackberries with Norovirus

Food Poison Journal

 

March 13th, 2020, WinCo Foods, LLC. of Boise, ID is recalling frozen Blackberries in a 16 oz. bag and frozen Berry Medley in 16 oz. and 32 oz. bags, manufactured by Rader Farms of Lynden, WA, because both products have the potential to be contaminated with Norovirus. Norovirus is a highly contagious virus. Typical symptoms of norovirus infection are acute onset of vomiting, watery, non-bloody diarrhea with abdominal cramps, and nausea. Systemic manifestations include, fever, myalgia and malaise, anorexia, and headache. Although most symptoms end within 48 hours, the elderly, young children and immunocompromised persons may develop prolonged or more severe symptoms.

WinCo Foods has removed the recalled products from store shelves.

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
