Research -WHO- The Global Burden of Listeriosis: A Systematic Review and Meta-analysis

The Lancet

Background

Listeriosis, caused by Listeria monocytogenes, is an important foodborne disease that can be difficult to control and commonly results in severe clinical outcomes. We aimed to provide the first estimates of global numbers of illnesses, deaths, and disability-adjusted life-years (DALYs) due to listeriosis, by synthesising information and knowledge through a systematic review.

Methods

We retrieved data on listeriosis through a systematic review of peer-reviewed and grey literature (published in 1990—2012). We excluded incidence data from before 1990 from the analysis. We reviewed national surveillance data where available. We did a multilevel meta-analysis to impute missing country-specific listeriosis incidence rates. We used a meta-regression to calculate the proportions of health states, and a Monte Carlo simulation to generate DALYs by WHO subregion.

Findings

We screened 11 722 references and identified 87 eligible studies containing listeriosis data for inclusion in the meta-analyses. We estimated that, in 2010, listeriosis resulted in 23 150 illnesses (95% credible interval 6061—91 247), 5463 deaths (1401—21 497), and 172 823 DALYs (44 079—676 465). The proportion of perinatal cases was 20·7% (SD 1·7).

Interpretation

Our quantification of the global burden of listeriosis will enable international prioritisation exercises. The number of DALYs due to listeriosis was lower than those due to congenital toxoplasmosis but accords with those due to echinococcosis. Urgent efforts are needed to fill the missing data in developing countries. We were unable to identify incidence data for the AFRO, EMRO, and SEARO WHO regions.

Research- EFSA – Tomatoes – Salmonella and Norovirus – Melons – Salmonella

EFSA

Tomatoes may be minimally processed to obtain ready-to-eat products, and these steps include selection, washing, cleaning, stem removal, cutting, packaging and storage. Epidemiological data from the EU have identified one salmonellosis outbreak and one Norovirus outbreak associated with tomato consumption between 2007 and 2012. Risk factors for tomato contamination by Salmonella and Norovirus were considered in the context of the whole food chain. Available estimates of the Salmonella and Norovirus occurrence in tomatoes were evaluated together with mitigation options relating to prevention of contamination and the relevance of microbiological criteria. It was concluded that each farm environment represents a unique combination of risk factors that can influence occurrence and persistence of pathogens in tomato production. Appropriate implementation of food safety management systems including Good Agricultural Practices (GAP), Good Hygiene Practices (GHP) and Good Manufacturing Practices (GMP), should be primary objectives of tomato producers. The current lack of data does not allow the proposal of a Hygiene Criterion for E. coli at primary production of tomatoes and it is also not possible to assess the suitability of an EU-wide E. coli Process Hygiene Criterion. There are Food Safety Criteria for the absence of Salmonella in 25 g samples of ready-to-eat pre-cut tomatoes as well as in unpasteurised tomato juice placed on the market during their shelf life. A Food Safety Criterion for Salmonella in whole tomatoes could be considered as a tool to communicate to producers and processors that Salmonella should not be present in the product. Testing of tomatoes for Salmonella could be limited to instances where other factors indicate breaches in GAP, GHP, GMP or HACCP programmes. It is currently not possible to provide a risk base for establishing a Norovirus Food Safety Criterion for these foods.

EFSA

Melons and watermelons are ready-to-eat foods, with an internal pH of 5.1 to 6.7 and can be consumed whole, as fresh-cut products or as fresh juices. Epidemiological data from the EU identified one salmonellosis outbreak associated with consumption of both pre-cut and whole melon between 2007 and 2012. Risk factors for melon and watermelon contamination by Salmonella were considered in the context of the whole food chain, together with available estimates of Salmonella occurrence and mitigation options relating to prevention of contamination and the relevance of microbiological criteria. It was concluded that each farm environment represents a unique combination of risk factors that can influence occurrence and persistence of Salmonella in melon and watermelon production. Appropriate implementation of food safety management systems including Good Agricultural Practices (GAP), Good Hygiene Practices (GHP) and Good Manufacturing Practices (GMP), should be primary objectives of producers. It is currently not possible to assess the suitability of an EU-wide E. coli Hygiene Criterion at primary production. The existing Process Hygiene Criterion for E. coli in pre-cut melons and watermelons aims to indicate the degree to which GAP, GHP, GMP or Hazard Analysis and Critical Control Points (HACCP) programmes have been implemented. There are Food Safety Criteria for the absence of Salmonella in 25g samples placed on the market during their shelf life of ready-to-eat pre-cut melon and watermelon and unpasteurised melon and watermelon juices. A Food Safety Criterion for Salmonella in whole melons and watermelons could be considered as a tool to communicate to producers and processors that Salmonella should not be present in the product. Since the occurrence of Salmonella is likely to be low, testing of whole melons or watermelons for this bacteriumcould be limited to instances where other factors indicate breaches in GAP, GHP, GMP or HACCP programmes.

EFSA – Salmonella

Salmonella is a bacterium that can cause an illness called salmonellosis in humans. In the European Union (EU), over 100,000 human cases are reported each year. EFSA has estimated that the overall economic burden of human salmonellosis could be as high as EUR 3 billion a year.

Research – Listeria monocytogenes in Aquatic Food Products—A Review

Wiley Online fish

With the increased demand for lightly preserved and/or ready-to-eat (RTE) food products, the prevalence of the foodborne pathogen Listeria monocytogenes has increased, which is a public health concern. The goal for this review is to discuss the incidence, epidemiological importance, and contamination routes of L. monocytogenes in various aquatic ecosystems, seafood products, and processing environments and to summarize the data obtained since the 1990s. L. monocytogenes primarily enters the food-production chain by cross-contamination in production plants, making this pathogen a major threat to the seafood industry. This pathogen generally contaminates food products at low or moderate levels, but the levels involved in listeriosis outbreaks are significantly higher. The majority of isolates from aquatic products belong to serotype 1/2a, and outbreaks have been linked to highly similar or even indistinguishable strains. Several seafood-processing plants are colonized by specific “in-house” flora containing special DNA subtypes of L. monocytogenes. In such cases, L. monocytogenes populations can persist and/or multiply despite the inherent obstacles to their growth in food preservation and manufacturing operations. Therefore, food-processing facilities must be designed carefully with an emphasis on effective cleaning and disinfecting operations in the production line.

Research – Outbreaks of non-O157 Shiga Toxin-Producing Escherichia coli Infection: USA

Cambridge Journals Ecoli Istock

Non-O157 Shiga toxin-producing Escherichia coli (STEC) infections are increasingly detected, but sources are not well established. We summarize outbreaks to 2010 in the USA. Single-aetiology outbreaks were defined as ≥2 epidemiologically linked culture-confirmed non-O157 STEC infections; multiple-aetiology outbreaks also had laboratory evidence of ≥2 infections caused by another enteric pathogen. Twenty-six states reported 46 outbreaks with 1727 illnesses and 144 hospitalizations. Of 38 single-aetiology outbreaks, 66% were caused by STEC O111 (n = 14) or O26 (n = 11), and 84% were transmitted through food (n = 17) or person-to-person spread (n = 15); food vehicles included dairy products, produce, and meats; childcare centres were the most common setting for person-to-person spread. Of single-aetiology outbreaks, a greater percentage of persons infected by Shiga toxin 2-positive strains had haemolytic uraemic syndrome compared with persons infected by Shiga toxin 1-only positive strains (7% vs. 0·8%). Compared with single-aetiology outbreaks, multiple-aetiology outbreaks were more frequently transmitted through water or animal contact.

 

UK – FSA – How Twitter can Reduce the Spread of Norovirus

The Guardian 

The Food Standards Agency (FSA) has embarked on a social media listening project that, it hopes, has the potential to predict outbreaks of the winter vomiting bug, norovirus, earlier than ever before.

FSA’s social media team sifted through Twitter data from the last norovirus outbreak during the winter of 2012-13, hunting for spikes in certain related key words and phrases being used in tweets. They then compared the frequency of the key words to the number of lab reports of confirmed norovirus cases in the same period.

They found significant correlations between spikes in the number of lab reports and spikes in conversations on Twitter using words and hashtags such as #winterbug, #norovirus, sickness bug, winter virus and vomiting.
