A combination of steam-venting packaging and microwave cooking may be used to inactivate Vibrio vulnificus and Vibrio parahaemolyticus in oyster meat. This study investigated temperature and pressure profiles in the headspace of a steam venting package with the steam-generated inside of the package resulting from microwave heating.

The global population is rising at an alarming rate, which is threatening food and nutritional security. Although chemical fertilizers and pesticides are important for achieving food security, their excessive usage critically affects soil health and adds up residues in the food chain. There is an increasing interest in identifying eco-friendly farm inputs that can improve crop productivity through sustainable agricultural practices.

This study aimed to determine the effect of capsicum oleoresin (CAP) on rumen fermentation and microbial abundance under different temperature and dietary conditions in vitro. The experimental design was arranged in a 2 × 2 × 3 factorial format together with two temperatures (normal: 39°C; hyperthermal: 42°C), two forage/concentrate ratios (30:70; 70:30), and two CAP concentrations in the incubation fluid at 20 and 200 mg/L with a control group.

Humans are exposed to Toxoplasma gondii infection as pet cats gradually become family members and represent an increasing public health risk worldwide. Toxoplasmosis diagnosis constitutes an important measure for disease prevention and control. In this study, real-time fluorescence quantitative loop-mediated isothermal amplification (qLAMP) and visual LAMP detection technologies were established to conduct tests of T.

Toxicosis through food and feed has remained a point of concern to food sectors across the globe. Although strict regulations have been implemented in developed and developing countries, their detection in food matrices is an evolving science. This study focuses on the development and fabrication of an electrochemical microfluidic biosensor that deploys aptamers to detect trace concentrations of Aflatoxin-M1 (AF-M1) in milk samples.

Application of essential oils to mitigate aflatoxin B1 (AFB1) contamination in food is a current research hotspot; however, their direct incorporation may cause toxic effects, and changes in food organoleptic properties.

Human norovirus (HuNoV) is a pathogenic agent that is frequently associated with foodborne disease outbreaks linked to fresh produce. Within microgreen production systems, understanding of virus transmission routes and persistence is limited. To investigate virus persistence on microgreen leaf surfaces, this study mimicked virus contaminations caused during microgreen handling by farm workers or during overhead irrigation with contaminated water.

In order to alleviate the toxic effects of aflatoxins B1 (AFB1) on inflammatory responses in the intestine, liver, and kidney of broilers, the aflatoxin B1-degrading enzyme, montmorillonite, and compound probiotics were selected and combined to make a triple-action compound mycotoxin detoxifier (CMD). The feeding experiment was divided into two stages.

Eggs constitute an important part of the Moroccan diet. However, contaminated eggs can cause a serious public health problem if consumed undercooked, uncooked, or used in unpasteurized egg foodstuffs. This study was carried out to evaluate the microbial contents of eggs according to their sales sector in Morocco.

The virulent genes expressed in Salmonella are one primary contributing factor leading to the high morbidity and mortality of salmonellosis in humans. This factor plays a role in infection of the host and transmission of disease. In this study, a total of 265 samples were collected from farmers' market in Xuzhou, Jiangsu Province, China, including 205 pork samples and 60 chicken samples.

Vibrio parahaemolyticus causes serious economic losses to the shrimp farming industry. There is still a lack of adequate understanding of the changes in the overall response of N. denticulata sinensis caused by V. parahaemolyticus, particularly with respect to gill tissue, which is severely damaged by the pathogen.

Presence of aflatoxins in agricultural products is a worldwide problem. Because of their high heat stability and resistance to most of the food processing technologies, aflatoxin degradation is still a big challenge.

Listeria monocytogenes is the most common foodborne pathogenic bacterium. L. monocytogenes can make biofilms on living or inanimate surfaces, helping it resist antimicrobial agents. This study aimed to evaluate the anti-biofilm effect of cell-free supernatants (CFS) of Bacillus subtilis KU43, B.

Journal of the Science of Food and Agriculture, Accepted Article. Background Rice straw (RS) is one of the largest sources of lignocellulosic, which is an abundant raw material for biofuels and chemicals. However, the natural degradation of RS under low temperature environment is the biggest obstacle of straw returning to field. Results In this test, one bacillus strain W118 was isolated.

As part of a program to reduce numbers of the human pathogen Campylobacter on retail chickens twenty-two broiler processing lines, representing over 90% of United Kingdom (UK) production, were characterized by enumerating Campylobacter on pooled neck skins after the exsanguination, scalding, defeathering, evisceration, crop removal, inside-outside washing, and air-chilling stages of processing.  Sixteen of the processing lines investigated showed significant (p<0.05) reductions in Cam

Non-typhoidal Salmonella (NTS) strains are among the major foodborne pathogens with emerging multidrug-resistant phenotypes. In this study, antimicrobial susceptibilities of a collection of  Salmonella isolates (n=54) recovered from poultry and bivalve molluscs were performed. The study also investigated the virulence and resistance genes profiling as well as the phylogenetic relationships through PFGE and ERIC/PCR fingerprinting.

Water is an essential part of food animal processing, and current processing practices use large volumes of water. Due to climate change, the food industry’s access to clean and inexpensive water is increasingly a challenge. The Food Safety and Inspection Service (FSIS) seeks evaluation by the National Advisory Committee on Microbiological Criteria for Food (NACMCF) to facilitate the safe reuse of sources of water in order to reduce water consumption.

A total of 57 pesticide residues were analyzed in 155 litchis and 153 longan samples collected from the three main producing provinces of China.

Background

Salmonellosis remains the second most common zoonosis in the European Union despite a long-term decreasing trend. However, this trend has been reported to have stagnated in recent years, particularly for Salmonella enterica serotype Enteritidis (SE).

Aim

Emerging evidence supports that the phage-prokaryote interaction drives ecological processes in various environments with different phage life strategies. However, the knowledge of phage-prokaryote interaction in the shrimp culture pond ecosystem (SCPE) is still limited.

Staphylococcus aureus is a gram-positive foodborne pathogen capable of forming strong biofilms. This study identified that anti-biofilm natural compound against S. aureus. Sinomenine, a natural compound, showed significantly reduced biofilm formation (31.97–39.86%), but no effect on bacterial growth was observed. The dispersion of preformed biofilms was observed by confocal laser scanning microscopy (CLSM).

Aflatoxin B1 (AFB1), a common contaminant in food and feed during storage, does great harm to human and animal health. Five essential oils (thymol, carvacrol, cinnamaldehyde, eugenol, and citral) were tested for their inhibition effect against Aspergillus flavus (A. flavus) in broth and feed. Cinnamaldehyde and citral were proven to be most effective against A. flavus compared to others and have a synergistic effect when used simultaneously.

Antibiotics, especially fluoroquinolones, have been exhaustively used in animal husbandry. However, very limited information on the occurrence and exposure assessment of fluoroquinolone residues in chicken and pork in China is available to date.

Infection and Immunity, Ahead of Print. Campylobacter jejuni is the most common cause of bacterial foodborne gastroenteritis and holds significant public health importance. The continuing increase of antibiotic-resistant Campylobacter necessitates the development of antibiotic-alternative approaches to control infections in poultry and in humans. Here, we assessed the ability of E.
