The Staphylococcus aureus enterotoxins are a superfamily of secreted virulence factors that share structural and functional similarities and possess potent superantigenic activity causing disruptions in adaptive immunity. The enterotoxins can be separated into two groups; the classical (SEA-SEE) and the newer (SEG-SE l Y and counting) enterotoxin groups. Many members from both these groups contribute to the pathogenesis of several serious human diseases, including toxic shock syndrome, pneumonia, and sepsis-related infections...

AIM: In autumn 2008, an outbreak of toxic honey poisoning was identified. The outbreak was not recognised initially until three cases from one family group presented to hospital, with a common factor of recent consumption of locally produced honey. The aim of this study was to investigate potential cases of this honey poisoning and determine which toxin was involved. METHOD: The incident was investigated retrospectively by Waikato District Health Board's Population Health unit and the New Zealand Food Safety Authority (NZFSA)...

Foodborne bacteria, inducing outbreaks of infection or poisoning, have posed great threats to food safety. Potentiometric sensors can identify bacteria levels in food by measuring medium's pH changes. However, most of these sensors face the limitation of low sensitivity and high cost. In this paper, we developed a high-sensitivity ion-sensitive field-effect transistor sensor. It is small sized, cost-efficient, and can be massively fabricated in a standard 65-nm complementary metal-oxide-semiconductor process...

BACKGROUND: When two or more people fall ill after eating the same food, this is called an outbreak of food poisoning or food-related infection. In the Netherlands, physicians have to notify the Municipal Health Services (GGD) of such outbreaks. The GGD informs the Netherlands Food and Consumer Product Safety Authority (NVWA). CASE DESCRIPTION: Two clusters of scombroid poisoning (histamine poisoning in this case after eating tuna) occurred in one month. Due to the quick reporting of patients by physicians, the GGD and the NVWA immediately tracked down the source...

Staphylococcus aureus is a common cause of food-borne intoxications. Several staphylococcal food poisoning outbreaks have been linked to consumption of raw milk cheeses and artisanal cheese production. However, information on Staph. aureus isolated from artisanal raw milk cheeses and small-scale dairy production environments is very limited. Therefore, we aimed to characterize Staph. aureus isolated along the artisanal raw milk production chain by determining (1) the population structure, and (2) the presence/absence of enterotoxin genes, mecA/C, and pvl...

Staphylococcus aureus is an important aetiological agent of food intoxications in the European Union as it can cause gastro-enteritis through the production of various staphylococcal enterotoxins (SEs) in foods. Reported enterotoxin dose levels causing food-borne illness are scarce and varying. Three food poisoning outbreaks due to enterotoxin-producing S. aureus strains which occurred in 2013 in Belgium are described. The outbreaks occurred in an elderly home, at a barbecue event and in a kindergarten and involved 28, 18, and six cases, respectively...

Staphylococcus aureus is the major cause of foodborne diseases worldwide. In this retrospective study, 84 S. aureus strains were characterized. The collection comprises 78 strains isolated during 1998 and 2014 from dairy products and tissue samples from livestock bred for dairy production in Sicily. One isolate was obtained from a pet (dog), one from an exotic animal (a circus elephant), and four human isolates were obtained during a severe food poisoning outbreak that occurred in Sicily in 2015. All the strains were characterized by pulsed-field gel electrophoresis (PFGE), for antibiotic resistance and presence of toxin genes...

Hepatitis A virus (HAV) is well known worldwide as a causative virus of acute hepatitis. In recent years, numerous cases of HAV infection caused by HAV-contaminated berries have occurred around the world. Because berries are often consumed without prior heating, reliable disinfection of the raw fruit is important in order to prevent HAV outbreaks. Previous studies have found that murine norovirus strain 1 (MNV-1) and human norovirus GII.4 were inactivated in heat-denatured lysozyme solution. In this study, we investigated whether or not heat-denatured lysozyme is effective in inactivating HAV and whether it could be an effective disinfectant for berries contaminated with HAV or MNV-1...

Background: Clostridium perfringens is ubiquitous in nature. It is a normal inhabitant in the intestinal tract of animals and humans. As the primary etiological agent of gas gangrene, necrosis and bacteremia, C. perfringens causes food poisoning, necrotic enteritis (NE), and even death. Epidemiology research has indicated that the increasing incidence of NE in poultry is associated with the withdrawal of in-feed antibiotic growth promoters in poultry production in response to government regulations...

In recent years much attention has been devoted to active packaging technologies that offer new opportunities for the food industry and food preservation. The spoilage of food products during post process handling leads to food contamination and causes life-threatening food-borne illness. The methicillin-resistant Staphylococcus aureus (MRSA) 090 is one of the food-borne pathogens associated with food poisoning that leads to an outbreak of perilous human infections worldwide. The development of resistance in bacteria and diffusion of coated synthetic preservatives into food are the major problem in food packaging industries...

Background: On January 9, 2015, in a rural town in Mozambique, over 230 people became sick and 75 died from an illness linked to drinking pombe, a traditional alcoholic beverage. Methods: An investigation was conducted to identify cases and determine the cause of the outbreak. A case was defined as any resident of Chitima who developed any new or unexplained neurologic, gastrointestinal, or cardiovascular symptom from January 9 at 6:00 a.m. through January 12. We conducted medical record reviews; healthcare worker and community surveys; anthropological and toxicological investigations of local medicinal plants and commercial pesticides; and laboratory testing of the suspect and control pombe...

The dancing mania erupted in the 14th century in the wake of the Black Death, and recurred for centuries in central Europe - particularly Germany, the Netherlands, and Belgium - finally abating in the early 17th century. The term "dancing mania" was derived from "choreomania," a concatenation of choros (dance) and mania (madness). A variant, tarantism, was prevalent in southern Italy from the 15th to the 17th centuries, and was attributed at the time to bites from the tarantula spider. Affected individuals participated in continuous, prolonged, erratic, often frenzied and sometimes erotic, dancing...

Staphylococcal food poisoning (SFP) is caused by staphylococcal enterotoxins (SEs) preformed in food materials. SE genes are encoded on mobile genetic elements and are widely found across Staphylococcus species including S. argenteus, although most SFP cases are caused by S. aureus. S. argenteus, recently discriminated from S. aureus as a novel species, are non-pigmented staphylococci phenotypically related to S. aureus. In 2014 and 2015, two independent food poisoning cases occurred in Osaka, Japan, in which non-pigmented staphylococci were predominantly isolated...

Staphylococcus argenteus is a novel species subdivided from Staphylococcus aureus. Whether this species can cause food poisoning outbreaks is unknown. This study aimed to investigate the enterotoxigenic activities of two food poisoning isolates suspected to be S. argenteus (Tokyo13064 and Tokyo13069). The results for phylogenic trees, constructed via whole genome sequencing, demonstrated that both isolates were more similar to a type strain of S. argenteus (MSHR1132) than any S. aureus strain. Moreover, the representative characteristics of S...

Human noroviruses (NoV) are the leading cause of human gastroenteritis in populations of all ages and are linked to most of the foodborne outbreaks worldwide. Hepatitis A virus (HAV) is another important foodborne enteric virus and is considered the most common agent causing acute liver disease worldwide. In the present study, a focused, low-density DNA microarray was developed and validated for the simultaneous identification of foodborne-associated genotypes of NoV and HAV. By employing a novel algorithm, capture probes were designed to target variable genomic regions commonly used for typing these foodborne viruses...
