Research – Listeria: What you need to know

Medical News Today

Listeriosis is a food-borne infection caused by Listeria bacteria. The majority of people who become infected might barely notice the illness. However, those at risk can be severely affected, and mortality rates are relatively high.

Listeriosis, also called Listeria, can be a serious infection; it strikes pregnant women, newborns, the elderly, and anyone with a weakened immune system.

In this article, we will look at the symptoms, diagnosis, and treatment of listeriosis. We will also discuss how the bacteria works, the best ways to avoid infection, and recent research into preventing the disease.

Fast facts on listeriosis

  • Listeriosis is an infection caused by Listeria monocytogenes
  • An estimated 260 Americans die of listeriosis yearly.
  • Only immunosuppressed individuals and pregnant women are at risk of a serious case of listeriosis.
  • Listeriosis can lead to septicemia or meningitis.
  • Pregnant women are 10 times more likely to be infected with Listeria than the general population.

Research – Listeria monocytogenes outbreaks related to commercially produced caramel apples: Developments in sanitation, product formulation, and packaging

Journal of Food Protection

Prior to a deadly 2014 listeriosis outbreak, caramel apples were not thought to be vehicles for the foodborne pathogen Listeria monocytogenes. The purpose of this review article is to summarize what has been learned from research prompted by this outbreak. An overview of the two L. monocytogenes outbreaks related to prepackaged caramel apples, along with a brief discussion of apple sanitation and the production processes used to make caramel apples, is provided. Research suggesting ways to prevent future outbreaks arising from caramel apples is summarized. This review is based on a qualitative analysis of literature as well as interviews with current caramel apple manufacturers. Sanitation, packaging, and storage procedures used by manufacturers in the past may be insufficient to effectively inactivate L. monocytogenes in the case of product contamination. Novel apple sanitation methods and product formulations to control L. monocytogenes on caramel apples have been developed and, in some cases, implemented in commercial production.

Research -EU One Health report: drop in reported zoonotic diseases in humans and foodborne outbreaks in 2020

EFSA

Campylobacteriosis was the most reported zoonosis in the EU in 2020, with 120,946 cases compared to more than 220,000 the previous year. It was followed by salmonellosis, which affected 52,702 people compared to 88,000 in 2019. The number of reported foodborne outbreaks also fell by 47%. These findings are based on the annual EU One Health zoonosis report, by EFSA and ECDC.

Experts acknowledged the impact of the COVID-19 pandemic in Europe in the remarkable drop in reported zoonotic diseases in humans – ranging from 7% to 53% depending on the reported disease in question – and foodborne outbreaks.

Possible factors behind the large decrease in cases include changes in health seeking behaviour, restrictions on travel and on events, the closing of restaurants, quarantine, lockdown, and other mitigation measures such as the use of masks, physical distancing and hand sanitisation.  

The next most commonly reported diseases were yersiniosis (5,668) and infections caused by Shigatoxin-producing E.coli (4,446). Listeriosis was the fifth most reported zoonosis (1,876 cases), mainly affecting people over the age of 64.

Listeriosis and West Nile virus infections were the diseases with the highest case fatality and hospitalisation rates – with most locally acquired human infections of West Nile virus reported in Greece, Spain and Italy.

The report also monitors foodborne outbreaks in the EU, events during which at least two people contract the same illness from the same contaminated food. A total of 3,086 foodborne outbreaks were reported in 2020. Salmonella remained the most frequently detected agent and caused about 23% outbreaks. The most common sources of salmonellosis outbreaks were eggs, egg products and pig meat.

The report also includes data on Mycobacterium bovis/caprae, BrucellaTrichinellaEchinococcus, Toxoplasma gondii, rabies, Q fever and tularaemia.

EFSA is publishing two interactive communication tools on foodborne outbreaks – a story map and a dashboard. The story map provides general information on foodborne outbreaks, their causative agents and implicated food vehicles. The dashboard allows people to search and query the large amount of data on foodborne outbreaks collected by EFSA from EU Member States and other reporting countries since 2015.

Research -Surveillance of Fresh Artisanal Cheeses Revealed High Levels of Listeria monocytogenes Contamination in the Department of Quindío, Colombia

MDPI

Listeriosis is a foodborne disease caused by Listeria monocytogenes. Because outbreaks of listeriosis are associated with the ingestion of contaminated dairy products, surveillance of artisanal cheeses to detect the presence of this microorganism is necessary. We collected three types of artisanal non-acid fresh cheese (Campesino, Costeño, and Cuajada) from 12 municipalities of the Department of Quindío, Colombia. L. monocytogenes was identified using VIDAS® and confirmed with API® Listeria Rapid Kit. L. monocytogenes was detected in 104 (53.6%) of the 194 artisanal fresh-cheese samples analyzed. The highest percentages of contamination were detected in Salento (90.9%), Calracá (65.5%), Armenia (64.9%), and Filandia (50%). A significant association between municipality and contamination with L. monocytogenes was identified. However, no association could be established between the type of cheese and the occurrence of the bacterium. This is the first study on the presence of L. monocytogenes in artisanal fresh cheeses sold in the municipalities of the Department of Quindío, and the findings revealed very high percentages of contaminated samples. The presence of L. monocytogenes in artisanal cheeses remains a public health threat in developing countries, especially Colombia, where existing legislation does not require the surveillance of L. monocytogenes in food. View Full-Text

Research – Prevalence of Listeria species on food contact surfaces in Washington State apple packinghouses

PubMed

The 2014 caramel apple listeriosis outbreak was traced back to cross-contamination between food contact surfaces (FCS) of equipment used for packing and fresh apples. For Washington State, the leading apple producer in the U.S with 79% of its total production directed to the fresh market, managing the risk of apple contamination with Listeria monocytogenes within the packing environment is crucial. The objectives of this study were to determine the prevalence of Listeria spp. on FCS in Washington State apple packinghouses over two packing seasons, and to identify those FCS types with the greatest likelihood to harbor Listeria spp. Five commercial apple packinghouses were visited quarterly over two consecutive year-long packing seasons. A range of 27 to 50 FCS were swabbed at each facility to detect Listeria spp. at two timings of sampling, (i) post-sanitation and (ii) in-process (three hours of packinghouse operation), following a modified protocol of the FDA’s Bacteriological Analytical Manual method. Among 2,988 samples tested, 4.6% (n=136) were positive for Listeria spp. Wax coating was the unit operation from which Listeria spp. were most frequently isolated. The FCS that showed the greatest prevalence of Listeria spp. were polishing brushes, stainless steel dividers and brushes under fans/blowers, and dryer rollers. The prevalence of Listeria spp. on FCS increased throughout apple storage time. The results of this study will aid apple packers in controlling for contamination and harborage of L. monocytogenes and improving cleaning and sanitation practices of the most Listeria-prevalent FCS.IMPORTANCE Since 2014, fresh apples have been linked to outbreaks and recalls associated with post-harvest cross-contamination with the foodborne pathogen L. monocytogenes These situations drive both public health burden and economic loss and underscore the need for continued scrutiny of packinghouse management to eliminate potential Listeria spp. niches. This research assesses the prevalence of Listeria spp. on FCS in apple packinghouses and identifies those FCS most likely to harbor Listeria spp. Such findings are essential for the apple packing industry striving to further understand and exhaustively mitigate the risk of contamination with L. monocytogenes to prevent future listeriosis outbreaks and recalls.
