UK – Listeriosis associated with pre-prepared sandwich consumption in hospital in England, 2017

Cambridge Org

A case of listeriosis occurred in a hospitalised patient in England in July 2017. Analysis by whole genome sequencing of the Listeria monocytogenes from the patient’s blood culture was identified as clonal complex (CC) 121. This culture was indistinguishable to isolates from sandwiches, salads and the maufacturing environment of Company X which supplied these products widely to the National Health Service. Whilst an inpatient, the case was served sandwiches produced by this company on 12 occasions. No other cases infected by this type were detected in the UK between 2016 and 2020. Between 2016 and 2020, more than 3000 samples of food, food ingredients and environmental swabs from this company were tested. Listeria monocytogenes contamination rates declined after July 2017 from 31% to 0.3% for salads and 3% to 0% for sandwiches. A monophyletic group of 127 L. monocytogenes CC121 isolates was recovered during 2016–2019 and was used to estimate the time of the most recent common ancestor as 2014 (95% CI of between 2012 and 2016). These results represent persistent contamination of equipment, food contact surfaces and foods at a food manufacturer by a single L. monocytogenes strain. Colonisation and persistent contamination of food and production environments are risks for public health.

UK – Report of the Independent Review of NHS Hospital Food

UK Gov

In the summer of 2019, there was an outbreak of listeriosis in which seven patients tragically died after eating hospital sandwiches contaminated with Listeria monocytogenes. Following this, the Health Secretary, Matt Hancock, announced a “root and branch” review of food served and sold in hospitals.
The scope of the review included the safety, nutrition, quality and production methods of food for patients, staff and visitors in NHS hospitals. In 2018 to 2019, the NHS spent £634 million on hospital food, representing approximately 6.7% of the total costs of running the NHS estate [10] or 0.6% of the total £114 billion 2018 to 2019 NHS budget [11]. It is the second biggest provider of meals in the UK public sector, serving 141 million inpatient meals [10] last year alone, to about 125,000 patients a day. This compares to 602 million school lunches [12] and 93 million prison meals [13].
There is a poor public perception of hospital food; and frequent critical press coverage of problems with both food that is on offer in hospitals to patients, staff and visitors, as well as wider concerns regarding food service. However, the evidence suggests that patients in NHS hospitals are satisfied, overall, with the quality of hospital food, with 22% of patients surveyed in 2019 rating the food they received as very good, and 36% rating it as good [14].
This contrasts with 39% of NHS staff, who felt that food and catering facilities offered in their workplaces were poor [15]. There is clearly scope for improvement. With a median spend of £4.56 per patient meal (including labour costs and overheads) [10], exceeding the budget of meals offered by other UK public services, the NHS should be demonstrating best practice in safely delivering nutritious, quality food to patients, and ensuring the least possible impact on our environment with best possible outcomes.
Better hospital food requires both national focus and leadership, but it is hard to deliver from the centre when power is devolved to individual trusts. We also need trusts to lead the change.
This report makes eight recommendations for system-level change. In Chapter 8 we propose that these are taken forward by an expert group with representation from across the sector and government. These apply mainly to government, NHS England and NHS Improvement, and national regulators.

Hospital food review10However, there are also actions that need to be delivered by trusts themselves. We have included a checklist for catering managers and chief executives which contains key principles of providing a good food service. We urge trust executive teams and boards to consider this list and what they can do to take their catering to the next level. We have tried not to be too prescriptive, as trusts are very diverse and what works in one place may not work in another.
However, these core principles are applicable to every type of service and should be carefully considered. Leadership engagement is key – hospital food is something that all boards we’ve engaged with really care about and are committed to. But commitment is not enough on its own – effective change needs two more things: data that gives insight for improvement, and a plan or strategy for getting the improvement done

Research – Healthcare-associated foodborne outbreaks in high-income countries: a literature review and surveillance study, 16 OECD countries, 2001 to 2019

Eurosurveillance

Yearly, 23 million foodborne disease illnesses and 5,000 deaths are estimated in the World Health Organization (WHO) European Region, and 41 foodborne Disability Adjusted Life Years (DALYs) per 100,000 population were estimated for the WHO Sub-Region EUR A in 2010 [1]. In Europe, a total of 5,146 foodborne and waterborne outbreaks, including 48,365 cases of illness and 40 deaths were reported to the European Food Safety Authority (EFSA) in 2018 [2]. Vulnerable populations, including elderly patients, immunocompromised patients, children younger than five years old and pregnant women are more susceptible to foodborne infections and are more prone to develop severe courses of disease compared with healthy people [3]. Therefore, healthcare is a setting where foodborne outbreaks (FBO) can cause considerable morbidity and mortality. In 2020, 20.6% of the European Union (EU) population was aged 65 years and older [4]. As the proportion of elderly people is projected to further increase, the share of the vulnerable population as patients in healthcare facilities (HCF) is likely to increase and thereby the risk associated with healthcare-associated foodborne outbreaks (HA-FBO). Personnel (medical and non-medical staff, food handlers etc) of HCF may also be at risk for HA-FBO and be a source of further spread in healthcare settings and elsewhere. This can cause major disruption of services [5].

So far, literature reviews have covered pathogens responsible for HA-FBO, including  [6],  [79] and norovirus [10,11] and focused on microbiological food safety issues in healthcare settings [5,12]. Between 2014 and 2019, a listeriosis outbreak in Germany affected 13 cases who had an inpatient stay in 12 different HCF during the incubation period [13]. In the United Kingdom (UK) in 2019, nine listeriosis cases of which seven died, had consumed sandwiches in seven HCF during the incubation period [14].

We conducted a literature review to describe the causative agents including bacteria, viruses, parasites and fungi, the incriminated food vehicles and other outbreak characteristics of HA-FBO in 37 countries that are members of the Organisation for Economic Cooperation and Development (OECD) [15]. Furthermore, we analysed German surveillance data and data from the EFSA on HA-FBO. The aim of this article is to describe the current status of HA-FBO in order to improve surveillance and provide public health recommendations for prevention.

USA – Potandon Produce Voluntarily Recalls Select White and Yellow Whole Onions Because of Possible Health Risk – Salmonella

FDA

Potandon Produce L.L.C. of Idaho Falls, Idaho is voluntarily recalling onions supplied from Keeler Family Farms and sold as Green Giant Fresh whole yellow onions in 2 lb. bags, 3 lb. bags, and 5 lb. bags and whole white onions in 2 lb. bags. The affected onions were delivered directly to three UNFI retail distribution centers (DCs) in Fargo, North Dakota; Bismarck, North Dakota and Hopkins, Minnesota between July 15 and July 30, 2021. This recall does not affect any other Green Giant Fresh products or include any Green Giant canned or frozen vegetable products.

The recalled onions are being recalled because they have the potential to be contaminated with Salmonella, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain. In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections (i.e., infected aneurysms), endocarditis and arthritis.

We have notified UNFI about this expanded recall and included the additional items in the product table list at the end of this press release. A cumulative list of all recalled onion items affected from both ProSource Produce and Keeler Family Farms is posted on our website at www.potandon.comExternal Link Disclaimer

Potandon Produce is issuing this press release and keeping the U.S. Food and Drug Administration informed of its recall process to assure that consumers are properly alerted.

The recall was initiated after the company learned it had sold onions supplied and recalled by Keeler Family Farms.

Anyone who has the recalled whole onions in their possession or has used them as an ingredient in a dish should not consume them and should either dispose of the product properly or return it to the place of purchase for a refund. Consumers with questions may contact the company’s recall coordinator at 1-800-637-8084, M-F from 8:30 am to 4:30 pm Mountain Time, or visit its website at www.potandon.comExternal Link Disclaimer.

Research – SALMONELLA ENTERITIDIS AND TYPHIMURIUM: TWO MAJOR SEROTYPES RESPONSIBLE FOR HUMAN INFECTIONS

Biomerieux

kswfoodworld salmonella

Salmonella enterica is a leading worldwide cause of foodborne human illnesses (WHO, 2015).

Salmonella isolates can be differentiated into serotypes according to the Kauffmann-White classification based on their flagellar (H) and somatic antigens (Grimont P. & Weill FX, 2007) or using genome-based serotyping approaches (Banerji S. et al ., 2020 ).

Among the> 2500 referenced serotypes (Ibrahim GM and Morin PM, 2018), Enteritidis and Typhimurium have proven to be both consistent contaminants along the food chain but more importantly as prominent isolates from diseases in humans (EFSA & ECDC, 2021).

These two serotypes are indeed particularly adapted to hostile environments such as farm animals or food industries’ environments and ultimately, human bodies. Their chromosomal or plasmid-borne virulence and regulatory factors often associated to antimicrobial resistance determinants (Cadel-six S. et al ., 2021) confer upon them striking fitness for survival and spread (Chen RA et al., 2019; Huang X. et al. al ., 2019; Guillén, S. et al ., 2021).
