Research – Listeria monocytogenes: a surprisingly adaptive bacterium

ANSES

Listeria monocytogenes is a ubiquitous bacterium found in food, livestock and wild animals, soil, water and vegetation. The European ListAdapt project focused on the ability of strains of this bacterium to adapt to these different environments. It found that this ability is independent of the strains’ environments of origin or their belonging to a given sub-group.

When two outbreaks occur in the same institution within a short period of time, an important health and social concern is generated. Two gastroenteritis outbreaks occurring a week apart in the same facility were reported in Lleida, Spain, in 2018. The objective of this study was to describe the clinical, epidemiological and microbiological investigation carried out and to determine the risk factors. Demographic data, food consumption and symptoms were collected. Health inspections of the facility were carried out. Risk ratio and their 95% confidence intervals were estimated for the implication of each food consumed. The attack rate was 89.7% in the first outbreak and 69.6% in the second outbreak. The most frequent symptoms in the first and second outbreak were abdominal pain (88.5% and 100%, respectively), vomiting (80.8% and 87.5%, respectively) and nausea (69.2% and 81.3%, respectively). The first outbreak was associated with the consumption of a salad and the second with a cheese omelet. Norovirus GII.6 was detected by RT-PCR and sequenced in both groups of students and in the food handlers who prepared the meals. These results highlight the importance of exclusion from work of food handlers with gastroenteritis, the adequate availability of mechanisms for correct hand washing and the correct cleaning of surfaces.

Japanese boxed meal maker banned from operations over food poisoning

English News

TOKYO, Sept. 25 (Xinhua) — A boxed meal maker in northeastern Japan has been banned by public health authorities from operating due to hundreds of food poisoning cases caused by its products, local media reported.

Yoshidaya, a local maker of boxed meals, commonly known as “bento” in Japanese, voluntarily suspended operations starting Sunday, after being banned from operations on Saturday by public health authorities in Aomori Prefecture.

Nearly 300 people from 24 prefectures in the country, more than half the number of prefectures across Japan, reported symptoms such as diarrhea and vomiting after eating bento meals supplied by the company based in Hachinohe city, Aomori Prefecture.

The number of patients might further increase, a public health official in Hachinohe said.

Staphylococcus aureus and Bacillus cereus, which cause food poisoning, were detected in the feces of the patients who ate bento meals as well as unopened products made by the company, Japan’s Jiji Press reported, citing Hachinohe public health officials.

Research – Study shows outbreaks increasing in Switzerland

Food Safety News

Researchers have highlighted increased foodborne outbreaks in Switzerland in the past 15 years.

Foodborne outbreaks in the country are identified by cantonal authorities and reported to the Federal Food Safety and Veterinary Office (FSVO). Between 2007 and 2021, 200 outbreaks were recorded. The highest amount during the study period was in 2021, and the lowest was in 2012.

At least 4,668 people fell ill, 303 were hospitalized, and 18 died. The top pathogens detected were Salmonella, Campylobacter, norovirus, and coagulase-positive staphylococci. Other incidents were caused by Scombroid poisoning, Bacillus, Listeria, and Clostridium perfringens.

Outbreaks took place in restaurants, canteens and catering sites, private households, kindergartens and schools, and takeaway establishments, according to the study published in the Journal of Consumer Protection and Food Safety.

Food items reported concerning outbreaks included mixed products (such as composite meals), fish and fish products, milk and milk products, and meat and meat products.

Research – Detection and Control of Foodborne Pathogens

MDPI

The globalization of food trade and the emergence of disease outbreaks involving several foodborne pathogens and foods has focused the attention of both the research community and consumers on food safety. Microbial contamination can involve different stages of food processing and distribution, with a potentially dramatic impact on human health and food business. Several methods, involving culture-dependent and -independent techniques, were developed to detect foodborne pathogens in the food supply chain. In this respect, gold-standard reference methods are currently available for most pathogens, but some of them are time-consuming and expensive. Moreover, routine controls carried out by manufacturers and food safety authorities are normally focused on bacteria and not on viruses and fungi, which can have a significant impact on food safety. In the European Union, the number of human cases caused by Noroviruses and other Caliciviruses increased sharply in 2021 [1]. Therefore, based on the evidence given by an increasing amount of research, control strategies show a clear trend towards molecular techniques, such as polymerase chain reaction (PCR), multiplex PCR, real-time PCR (qPCR), reverse transcriptase PCR (RT-PCR), DNA microarrays, nucleic acid sequence-based amplification (NASBA), isothermal DNA amplification techniques, and next-generation sequencing (NGS) [2]. Moreover, to expand the knowledge on the behaviour of pathogens in food environments, proteome profiling and biosensors shed light on how these microorganisms interact and prevail in food systems [3].

Research – Natural Antimicrobial Agents Utilized in Food Preservation

MDPI

Since the initial transformation of food surpluses, improving food quality and safety are of principal importance to human health. Due to the mass production (eggs, poultry, meat, grains, and pulses) of huge quantities of food, as well as storage and transport, food technologists are faced with challenges of contamination, undesirable microbial growth, the production of toxins, or the deterioration of food (food spoilage). Different food preserving methods (drying, smoking, etc.) have been developed throughout human history to increase the storage time of perishable raw materials or improve diets. For a long time, chemical preservatives used in the prevention of food spoilage or foodborne diseases were considered convenient for consumer protection. Effective in small concentrations and maintaining the sensory properties of food, as well as exhibiting stability at different temperatures or pH values, made their application in the prevention of food spoilage highly applicable. Indeed, they reduce food losses, increase quality, extend shelf life, and enable the development of new formulations as well as food stabilization and standardization [1]. Although consumers still demand safe, fresh-like (minimally processed), nutritionally highly valuable, high-quality foods, attitudes towards chemical conservatives have changed in contemporary nutrition. The continuous intake of chemicals during our (increasingly long-lived) lifetime and the documented adverse activity have changed consumer perceptions and attitudes towards synthetic preservatives in food technology [2]. More natural food production or the application of natural compounds in maintaining food safety have become highly desirable for many consumers in developed countries. Bio-preservatives, naturally occurring compounds from plants, animals, or microorganisms, can be successfully used in extending the shelf life of food, the inhibition/elimination of spoilage and pathogenic microorganisms, and the enhancement of food’s functionality and quality. Natural antimicrobials can be used directly in product formulation, incorporated into packaging material, or surface-coated to prevent spoilage processes or pathogen growth [3].
The most important naturally occurring used compounds in the food industry are essential oils, enzymes, and edible coatings.
Essential oils are highly volatile compounds from herbs and spices such as basil, thyme, oregano, cinnamon, clove, and rosemary, and are used to reduce spoilage microorganisms, increase overall food quality, and to inhibit food-borne pathogens such as SalmonellaListeria monocytogenesEscherichia coliBacillus cereus, and Staphylococcus aureus [4]. Essential oils are effective in inhibiting fungal growth as well as mycotoxin synthesis, reducing fungal damage and health risks [5,6]. Although essential oils are mainly used in the food industry as flavorings, by increasing knowledge of their modes of action and interactions with food matrix components, they can be successfully used in reducing targeted microbes.
Enzymes from animal sources such as lyzozime, lactoferrin, and bacteriocins (natamycin, nisin, pediocin, and reuterin) from bacteria are used in small concentrations in a similar way to prolong shelf life and inhibit pathogen proliferation [7].
Edible coatings, thin layers of naturally occurring polymers, with or without the addition of essential oils or enzymes, used for food coating reduce moisture loss, reduce microbial contamination, and minimize the impact of packaging materials on the environment [8].
Many natural compounds are promising for replacing synthetic food additives while improving overall quality and safety. Through cooperation, food scientists and food technologists can help meet consumer needs for safe and nutritionally valuable food without the adverse effect of synthetic preservatives.
This Special Issue aims to publish quality articles on natural antimicrobials in food preservation, their activity towards pathogens and contaminants, and novel formulations or applications in the production of safe and healthy foods.

Hong Kong – CFS urges public not to consume a kind of prepackaged cheese sauce imported from Netherlands suspected to be contaminated with Bacillus cereus

CFS

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (September 25) urged the public not to consume a kind of prepackaged cheese sauce imported from the Netherlands due to possible contamination with Bacillus cereus. The trade should stop using or selling the affected batches of the product immediately if they possess it.

Product details are as follows:

Product name: DIP NACHO CHEESE STYLE
Brand: Santa Maria
Place of origin: The Netherlands
Net weight: 250 grams
Batch code: 2329019 and 2329231
Best-before date: June 7, 2025 and June 20, 2025
Importer: Pear & Carrot Limited

“The CFS received a notification from the Rapid Alert System for Food and Feed of the European Commission that the above-mentioned batches of product might have been contaminated with Bacillus cereus and are being recalled. Upon learning of the incident, the CFS immediately contacted the concerned local importer for follow-up. A preliminary investigation found that the above-mentioned importer had imported into Hong Kong and ordered the affected batches of the product concerned,” a spokesman for the CFS said.

The importer concerned has stopped sales, has removed the imported affected product from shelves and has initiated a recall according to the instructions of the CFS. Enquiries about the recall can be made to the importer’s hotline at 3616 0248 during office hours. The CFS will also mark and seal the product ordered by the importer upon its arrival to Hong Kong and ensure that the product will not enter the local market.

“Bacillus cereus is commonly found in the environment. Unhygienic conditions in food processing and storage may give rise to its growth. Consuming food contaminated with excessive Bacillus cereus or its heat-stable toxins may cause gastrointestinal upset such as vomiting and diarrhoea,” the spokesman said.

The spokesman urged consumers not to consume the affected product if they have bought any. The trade should also stop using or selling the product concerned immediately if they possess it.

The CFS will alert the trade to the incident, and will continue to follow up and take appropriate action. The investigation is ongoing.
