Research – Rare Recombinant GI.5[P4] Norovirus That Caused a Large Foodborne Outbreak of Gastroenteritis in a Hotel in Spain in 2021 – Food Handler

Posted on March 31, 2023 by | Leave a comment

Journals ASM

Noroviruses are among the most important causes of acute gastroenteritis (AGE). In summer 2021, a large outbreak of norovirus infections affecting 163 patients, including 15 norovirus-confirmed food handlers, occurred in a hotel in Murcia in southeast Spain. A rare GI.5[P4] norovirus strain was identified as the cause of the outbreak.
The epidemiological investigation determined that norovirus transmission might have been initiated through an infected food handler. The food safety inspection found that some symptomatic food handlers continued working during illness. Molecular investigation with whole-genome and ORF1 sequencing provided enhanced genetic discrimination over ORF2 sequencing alone and enabled differentiation of the GI.5[P4] strains into separate subclusters, suggesting different chains of transmission. These recombinant viruses have been identified circulating globally over the last 5 years, warranting further global surveillance.
IMPORTANCE Due to the large genetic diversity of noroviruses, it is important to enhance the discriminatory power of typing techniques to differentiate strains when investigating outbreaks and elucidating transmission chains. This study highlights the importance of (i) using whole-genome sequencing to ensure genetic differentiation of GI noroviruses to track chains of transmission during outbreak investigations and (ii) the adherence of symptomatic food handlers to work exclusion rules and strict hand hygiene practices. To our knowledge, this study provides the first full-length genome sequences of GI.5[P4] strains apart from the prototype strain.

St Kitts and Nevis has once again addressed the issue of acute gastroenteritis on island.

The St Kitts and Nevis Information Service (SKNIS) says according to a report from the Chief Medical Officer, over the past few weeks several children and adults in the Federation have been diagnosed with acute gastroenteritis (AGE).

It notes this outbreak of AGE is not unique to St Kitts and Nevis, and that a similar trend is observed in several CARICOM member states.

It is reported the Caribbean Public Health Agency (CARPHA) has noted a multi-country increase in reported cases of AGE in children and adults and based on epidemiological information, the most likely cause of this AGE multi-country outbreak is Norovirus.

Norovirus was confirmed on more than one of the cruise ships travelling in the Caribbean and the UK Health Security Agency reports a sharp increase in confirmed cases of norovirus in recent weeks.

Norovirus can only be confirmed through laboratory testing.

Samples were sent off to CARPHA for analysis on Monday, March 27, 2023.

USA – Listeria Outbreak Linked to Deli Meat and Cheese

Posted on March 31, 2023 by | Leave a comment

CDC

This outbreak is over. Even when there are no ongoing Listeria outbreaks, people who are pregnant, aged 65 or older, or have a weakened immune system should reheat deli meat and deli-sliced cheese to an internal temperature of 165°F or until steaming hot to kill any germs.

  • States: 6
  • Recall: No

Listeria in Deli Meat and Deli-Sliced Cheese

Deli meats (cold cuts, lunch meats, hot dogs, and pâtés) and deli-sliced cheeses are known sources of Listeria illnesses. This is because Listeria can easily spread among food, food preparation surfaces like deli slicers, and hands. Listeria is a hardy germ that can be difficult to fully remove once it is present in a deli or a food processing facility. It can survive and grow at cold temperatures in a refrigerator.

Outbreak Investigation Summary

Data showed that deli meat and cheese bought at deli counters in multiple states were the likely sources of this outbreak.

  • Of 12 people interviewed, 11 reported eating meat or cheese from deli counters.
  • The outbreak strain of Listeria was found in open packages of mortadella, ham, and salami sliced at the deli, as well as a deli in Brooklyn, New York.

A single deli or food source was not identified. It is difficult for investigators to identify the specific source of outbreaks linked to deli meats and cheeses. This is because Listeria spreads easily between food and the deli environment, and it can live for a long time in deli display cases and on equipment. A contaminated food likely introduced the outbreak strain of Listeria into delis in multiple states.

Research – Multi-country outbreak of Salmonella Virchow ST16 infections linked to the consumption of meat products containing chicken meat

Posted on March 31, 2023 by | Leave a comment

EFSA

Abstract

Since June 2017, a persistent cross-border outbreak of Salmonella Virchow ST16 has been ongoing in five European Union/European Economic Area (EU/EEA) countries, the United Kingdom (UK), and the United States (US). A total of 210 cases have been reported from the following countries: Denmark (2), France (111), Germany (26), Ireland (4), the Netherlands (34), the UK (32), and the US (1). Among the interviewed cases (55), hospitalisation rates ranged from 16.7% (2/12) in the UK, to 29.4% (5/17) and 38.5% (10/26) in France and Germany, respectively. No deaths have been reported. A majority of cases have been linked to local restaurants serving kebab meat. The number of confirmed cases represents only a small proportion of all infections in the EU/EEA, partly due to the varying sequencing capacities of countries.

The comparison of the representative outbreak strains with the available genome profiles of S. Virchow ST16 from non-human isolates, revealed that most of the matching isolates belonged to broiler meat and broiler-related environments, thereby supporting the hypothesis of chicken meat as a vehicle of infections.

The available information from case interviews, traceback investigations, and whole genome sequencing (WGS) cluster analysis, showed that kebab meat products containing contaminated chicken meat are the likely vehicles of infections, and that the clone has been circulating in the EU poultry meat production chain at least in France, Germany, and the Netherlands. In the absence of batch numbers of the contaminated kebab products and related Salmonella testing information, the source(s) of the infections could not be established.

New infections are likely to occur in the EU/EEA affecting any age group, until further investigations are performed to identify the source(s) and point(s) of contamination along the chicken meat production chain, including the primary production upstream lines. This will allow appropriate control measures to be implemented.

USA – Stewart Parnell looks for better Habeas in Atlanta than he just had in Mid-Georgia – Peanut Butter Salmonella Outbreak

Posted on March 29, 2023 by | Leave a comment

Food Safety News

A decade after his indictment and a year after United States Magistrate Judge Thomas Q. Langstaff denied his petition for early release, one-time peanut butter mogul Stewart Parnell still has one more card to play.

Parnell, 68, has 15 years to run on his sentence imposed after a 2014 jury conviction for numerous federal felonies associated with the deadly 2008-09 multistate Salmonella outbreak traced to his Peanut Corporation of America peanut processing facility in Blakely, GA. He is serving his time at the federal correctional facility at Hazelton, WV.

Parnell begins this year with a new appeal of his Habeas corpus petition in the U.S. Court of Appeals for the 11th U.S. Circuit in Atlanta. A Habeas petition claims unlawful detention or imprisonment because of constitutional infractions. It can open cell doors,

Research – A foodborne outbreak of Campylobacteriosis at a wedding – Melbourne, Australia, 2022

Posted on March 29, 2023 by | Leave a comment

1 Health

Abstract

Campylobacter is the most common bacterial cause of foodborne gastroenteritis in Australia; how-ever, outbreaks caused by the pathogen are relatively uncommon. In March 2022, the Victorian Department of Health was notified of a gastrointestinal illness in 20 guests following attendance at a wedding reception.

Two of these individuals were notified with laboratory-confirmed campylobacteriosis, and an investigation was undertaken to identify the source of the infection and implement strategies to prevent further illness. A case-control study was conducted to determine the likely source of infection. Cases were defined as attendees of the wedding reception, with onset of diarrhoea and/or abdominal cramping 1–10 days after attending the function. Controls were randomly selected from the remaining list of non-ill guests. Cases and controls were interviewed using a standardised, menu-based questionnaire.

Food preparation processes were documented, and food samples collected.

A total of 29 wedding guests met the case definition. Cases reported onset of illness 2–5 days fol-lowing the wedding and major symptoms included abdominal cramping (100%), diarrhoea (90%), headache (79%), and fever (62%). Two cases were hospitalised, one with ongoing secondary neu-rological sequelae.

Illness was significantly associated with consumption of a duck breast brioche canapé containing duck liver parfait (odds ratio = 2.85; 95% confidence interval: 1.03–7.86). No leftover food samples were available for testing.The investigation found that the duck canapé was the likely vehicle of infection. Consistent with the literature on Campylobacter transmission, it is likely that inadequate cooking of the duck liver for the parfait was the contributing factor that led to illness. This highlights the risks posed by undercooked poultry dishes, and shows that education of food handlers remains a priority.

UK reveals more sick in multi-country Salmonella outbreak

Posted on March 29, 2023 by | Leave a comment

Food Safety News

The number of patients in a Salmonella outbreak in the United Kingdom has increased to more than 130.

It was previously reported that 81 people were sick in the UK as part of a multi-country Salmonella Mbandaka outbreak. As of early March, there are 132 UK cases, according to the Food Standards Agency (FSA).

Whole genome sequencing confirmed a microbiological link between ready-to-cook chicken breast manufactured in Ukraine, and cases in Finland, Estonia, and the UK. The chicken was supplied to the UK from Ukraine via the Netherlands, and a company in the Netherlands has recalled products sent to the UK. All items were for food service use and have been withdrawn from the UK market.

In May 2022, the UK reported 31 Salmonella Mbandaka cases with 25 from England and three each in Scotland and Wales with sample dates between Sept. 2021 and April 2022. Four were admitted to the hospital and one person died.

As of late 2022, Finland had 89 cases while a few patients also lived in the Czech Republic, Estonia, France, Germany, Ireland, the Netherlands, and Israel. Cases occurred in all age groups.

Ready-to-eat (RTE) chicken products or fresh chicken meat, such as those used in sandwiches and wraps, were said to be the likely vehicles of infection, according to an assessment by the European Centre for Disease Prevention and Control (ECDC).

Finnish officials linked the suspected RTE products to an Estonian company, which received processed chicken meat from different suppliers.

ECDC said epidemiological data and microbiological evidence from whole genome sequencing of human isolates indicated there were several sources through different distribution chains.

USA – FDA Warning Letter – Mariscos Bahia, Inc. – Salmonella Outbreak

Posted on March 23, 2023 by | Leave a comment

FDA

The United States Food and Drug Administration (FDA) and the California Department of Public Health (CDPH) inspected your seafood processing facility, Mariscos Bahia Inc, located at 8300 Rex Rd., Pico Rivera, CA 90660-3719 from October 6 to October 21, 2022. The inspection was initiated as part of a multistate foodborne outbreak investigation of Salmonella Litchfield (S. Litchfield) infections linked to seafood, including fresh, raw salmon, supplied by your facility. According to the Centers for Disease Control and Prevention (CDC), 39 people from 4 states were infected with the outbreak strain of S. Litchfield. During our inspection we collected environmental samples (swabs) from various areas in your facility, including areas that are near food during processing operations. FDA laboratory analyses found the presence of the outbreak strain of S. Litchfield and two additional Salmonella strains, Salmonella Mbandaka (S. Mbandaka) and Salmonella Oranienburg (S. Oranienburg), which are human pathogens, in your facility. On October 20, 2022, your firm recalled various types of fresh fish processed at your facility and distributed between June 14, 2022 and October 17, 2022, because they had the potential of being contaminated with Salmonella. FDA and CDC have determined, based upon the epidemiologic, traceback evidence, and whole genome sequencing (WGS) matches between clinical and FDA environmental samples, that fresh salmon processed at your facility was the likely source of this multistate S. Litchfield outbreak.
