Campylobacteriosis is one of the most important reported zoonosis worldwide. Besides poultry other sources of infection have been described. In the current study, the incidence of Campylobacter spp. was assessed over a five-month period in mussel samples harvested from one of the most important producing areas (Galicia, NW Spain) in Europe. Out of 91 samples screened, 8% were positive and identified as C. lari by MALDI-TOF and whole genome sequencing.

Effects of risk-based control of Campylobacter spp. in Danish broiler farms and flocks were simulated, to assess potential reductions of human risk of campylobacteriosis, associated to the consumption of poultry meat produced in Denmark. Two national data streams were used and represented: Flock status by testing cloacal swabs (CS, 2018–2019) and carcass status by testing leg skin samples (LS, 2019).

The potential risk-based improvement of the Salmonella Dublin surveillance programme in Danish dairy herds was investigated, considering herd status misclassifications due to testing errors. The programme started in October 2002. Currently (early 2021) all dairy herds are classified based on quarterly bulk tank milk (BTM) testing with an indirect antibody ELISA (iELISA).

The microbiological quality of fermented products such as salami are highly dependent on the interaction of environmental conditions during its fabrication. These effects may be predicted by mathematical modeling, and this approach has been adopted in several occasions. The aim of this study was to validate the Gamma concept model to predict Salmonella behavior during salami manufacturing in environmental conditions found in small scale Brazilian manufacturer.

Campylobacteriosis is an emerging foodborne illness which is frequently linked to the consumption of inadequately prepared poultry. The purpose of this study was to assess the risk associated with thermotolerant Campylobacter spp. in chicken döner kebab and to estimate the number of campylobacteriosis cases due to its consumption in Tlemcen city (Algeria).

Quantitative microbiological risk assessment (QMRA) studies have suggested that control options to reduce the concentration of Campylobacter spp. in broiler chicken caeca may be highly effective at reducing the risk of human campylobacteriosis. These QMRA studies have been updated based on scientific evidence obtained in the past decade.

ibrio parahaemolyticus is the main cause of foodborne gastroenteritis, which is widely distributed in shellfish and other seafood. Most V. parahaemolyticus are nonpathogenic, and only a few types, such as serotype O3:K6, are pathogenic, which is also the most prevalent strain in Asia. However, the relationship between this serotype and pathogenicity has yet to be established. The waaf gene is located in the O antigen synthesis gene cluster.

Toxoplasma gondii is a worldwide occurring apicomplexan parasite.

Toxoplasma gondii is a parasite of significant public health importance. We attempted to detect T.

This study investigates consumer experiences of food environments and food acquisition practices during the Covid-19 pandemic. Our rapid assessment online survey featured a convenience sample of 2015 individuals from 119 countries, spanning Western Europe, North America, Latin America, Asia-Pacific, and Africa. Data collection took place in April 2020 during the second month of the pandemic.

Maize grown in both North and South America are now predominantly genetically modified (GM) cultivars with some resistance to herbicide, pesticide, or both.

Native and chemically modified whey proteins and their peptide derivatives are encountering the interest of nutraceutical and pharmaceutical industries, due to the numerous properties, ranging from antimicrobial to immunological and antitumorigenic, that result in the possibility to employ milk and its protein components in a wide range of treatment and prevention strategies.

Cordycepin (Cor) is a potent bioactive constituent of Cordyceps militaris, which has been used as a daily tonic food and herbal medicine in Asia. Cadmium (Cd) is a widespread neurotoxic environmental contaminant, and it has been detected as a pollutant in Cordyceps militaris. However, the potential effects of Cor on Cd neurotoxicity remains unknown.

The Coronavirus outbreak globally has changed the medical system and also led to a shortage of medical facilities in both developing and underdeveloped countries.

Toxoplasmosis is a disease caused by T. gondii, a protozoa which affects humans and animals and is widely distributed worldwide. In humans, there is great concern due to the serious consequences that can occur in the infection of pregnant women and the newborn. The early diagnosis of gestational toxoplasmosis is important for treatment to be carried out in order to prevent vertical transmission or reduce damage.

The surface protein SasX, has a key role in methicillin-resistant Staphylococcus aureus (MRSA) colonization and pathogenesis, and has been associated with the epidemic success of some MRSA clones.

It has been reported that some mutations in the genome of hepatitis B virus (HBV) may predict the outcome of the virus infection. However, evolutionary data derived from long-term longitudinal analysis of entire HBV genomes using next generation sequencing (NGS) remain rare. In this study, serum samples were collected from asymptomatic hepatitis B surface antigen (HBsAg) carriers from a long-term prospective cohort.

This study investigated the persistence of Escherichia coli O157:H7 on the surface of leafy greens, and penetration into intercellular spaces through stomatal pores. This was done by determining the role of leafy green-mimicking microgrooves (normal and fully open stomata and micro-sized crevices) and the roles of pore size and orientation on proliferation of E. coli. Microgroove-embedded microfluidics were fabricated using soft-lithography.

The effect of high pressure processing (HPP) compared to Holder pasteurization (HoP) (62.5 °C, 30 min), on the inactivation of cytomegalovirus (CMV) and hepatitis

In this study, the antibacterial activities of thyme essential oil nanoemulsions (TEON) prepared by ultrasonication (US) and high-pressure homogenization (HPH) were evaluated via minimum inhibitory concentration (MIC), 

Although irradiation has been used to destroy bacteria and molds in spices globally, a new technology is needed to alleviate public fears of irradiation, the high cost of irradiated food, and environmental contamination at the irradiation facility.

The human diarrheal disease cholera is caused by the bacterium Vibrio cholerae. Efforts to develop animal models that closely mimic cholera to study the pathogenesis of this disease began >125 years ago. Here, we review currently used non-surgical, oral inoculation-based animal models for investigation of V.

The purpose of this study was to explore the effect of Lycopene in Staphylococcus aureus (S. aureus) (USA 300)-induced inflammation and to elucidate the potential mechanism of its action. The direct effect of Lycopene on S. aureus USA300 growth was determined via growth curves assay, and α-hemolysin (Hla) release of S. aureus USA300 using hemolysis assay.
