Rapid, accurate, and simultaneous screening of V. parahaemolyticus and its antimicrobial resistance genes (ARGs) is significant for mariculture monitoring and food safety. Thus, we developed an integrated RPA-microfluidic method to simultaneously detect V. parahaemolyticus and its ARGs floR, sul1 and qnrA.

Infection with Vibrio mimicus in the Siluriformes has demonstrated a rapid and high infectivity and mortality rate, distinct from other hosts. Our earlier investigations identified necrosis, an inflammatory storm, and tissue remodeling as crucial pathological responses in yellow catfish (Pelteobagrus fulvidraco) infected with V. mimicus.

For the past years, Salmonella has been one of the major foodborne pathogens in Europe, leading to the development of several control efforts to reduce its impact on human health. Poultry meat has been consistently implicated in foodborne cases of salmonellosis.

Abstract BACKGROUND This study evaluated for the first time the potential of orange passion fruit as a base for alcoholic and acetic fermentations, with a view to assessing its profile of organic acids and polyphenols, in vitro digestion, and biological activities. RESULTS In terms of aliphatic organic acids, malic acid was the majority in the wine (3.19 g L−1), while in the vinegar, it was acetic acid (46.84 g L−1).

The 2021 FSIS Stabilization Guidelines for Meat and Poultry Products (Appendix B) Option 1.2 limits Phase 1 cooling from 48.8-26.7°C in uncured meats to 1 hour. However, this time restriction is impractical to achieve in large diameter whole muscle products.

Nowadays, the discovery of alternative natural antimicrobial substances such as bacteriophages, essential oils, and other physical and chemical agents is developing in the food industry. In this study, nine bacteriophages were isolated from various parts of raw chickens and exhibited lytic activities against L. monocytogenes and various Listeria spp.

Tree nuts have been associated with several foodborne outbreaks and recalls in the U.S. While thermal decontamination methods can inactivate pathogens, they come with challenges of varying severity on the product quality. Thus, this study evaluated the effects of nonthermal intense pulsed light (IPL) on Salmonella Typhimurium inactivation and quality attributes of pecan halves.

Vegetable oils are essential constituent of the daily dietary intake. Nevertheless, they often contain aflatoxin B1 (AFB1) and benzo(a)pyrene (BAP). Physical adsorption is the most commonly used detoxification method in the vegetable oils industry. Regrettably, the previously reported adsorbents have exhibited limited efficacy, rendering them inadequate for meeting the requirements of large-scale production of edible oils.

Background Estimated hepatitis C prevalence within the Veterans Health Administration is higher than the general population and is a risk factor for advanced liver disease and subsequent complications. We describe the hepatitis C care continuum within the Veterans Health Administration 1 January 2014 to 31 December 2022.

Purple yam (Dioscorea trifida) has high agricultural productivity in the Amazon region but has not been much investigated. Multivariate strategies were employed to optimize the method to obtain a food extract rich in functional compounds.

Clostridium perfringens spores, which are extremely resistant and difficult to kill, can easily cause food spoilage and foodborne diseases. In this study, the effect of simultaneous ultrasound and heat (thermosonication, TS) treatment for C. perfringens spore inactivation was investigated. The TS treatment at 26.67 W/mL and 80 °C or 90 °C for 30 min resulted in 5.77 and 5.89 log inactivation of C. perfringens spores, respectively.

Salmonella is one of the world’s leading causes of zoonotic and foodborne illnesses. Recently, antimicrobial resistance (AMR) has become one of the most critical challenges to public health and food safety. Herein, we employed a meta-analysis to determine the pooled prevalence and spatiotemporal distribution of serovars and antimicrobial resistance in NTS in Burkina Faso.

Salmonellosis, an infectious disease caused by the Salmonella species, encompasses a broad spectrum of clinical manifestations, ranging from mild self‐limiting gastroenteritis to severe systemic infections. It affects millions of people annually, causing immense morbidity and economic losses worldwide. This study aims to evaluate the occurrence of Salmonella in water and raw foods, focusing on meat, fish, shellfish, and vegetables consumed in the city of Nampula, north of Mozambique.

Abstract Cultured meat, which involves growing meat in a laboratory rather than breeding animals, offers potential benefits in terms of sustainability, health, and animal welfare compared to conventional meat production. However, the cultured meat production process involves several stages, each with potential hazards requiring careful monitoring and control. Microbial contamination risks exist in the initial cell collection from source animals and the surrounding environment.

Applied and Environmental Microbiology, Ahead of Print. Marine bacteria experience fluctuations in osmolarity that they must adapt to, and most bacteria respond to high osmolarity by accumulating compatible solutes also known as osmolytes. The osmotic stress response and compatible solutes used by the coral and oyster pathogen Vibrio coralliilyticus were unknown. In this study, we showed that to alleviate osmotic stress V.

Strain MP-1014T, an obligate halophilic actinobacterium, was isolated from the mangrove soil of Thandavarayancholanganpettai, Tamil Nadu, India. A polyphasic approach was utilized to explore its phylogenetic position completely. The isolate was Gram-positive, filamentous, non-motile, and coccoid in older cultures. Ideal growth conditions were seen at 30 °C and pH 7.0, with 5% NaCl (W/V), and the DNA G + C content was 73.3%.

Hepatitis E virus is a worldwide emerging foodborne pathogen; raw or undercooked meats and liver pork products can cause infection through the orofecal route. In Central-Southern Italy, small traditional farming method, associated with the possibility of environmental sharing with wild species, can facilitate HEV diffusion and persistence.

Aflatoxin B1 (AFB1) is an unavoidable environmental toxin. The accumulation of AFB1 and its metabolites in the liver poses a threat to both human and animal health. Curcumin exhibits anti-oxidative, anti-tumor, and anti-inflammatory properties. There is no report on the mechanism regarding how curcumin relived liver necroptosis in chickens induced by AFB1 based on the regulatory network of ceRNA.

Microbiology Resource Announcements, Ahead of Print. A Pacific native lineage of Vibrio parahaemolyticus ST36 serotype O4:K12 was introduced into the Atlantic, which increased local source illnesses. To identify genetic determinants of virulence and ecological resiliency and track their transfer into endemic populations, we constructed a complete genome of a 2013 Atlantic-traced clinical isolate by hybrid assembly.

Campylobacter jejuni continues to be a major public health issue worldwide. Poultry are recognized as the main reservoir for this foodborne pathogen. Implementing measures to decrease C. jejuni colonization on farms has been regarded as the most effective strategy to control the incidence of campylobacteriosis. The probiotics supplementation has been regarded as an attractive approach against C. jejuni in chickens.

Aflatoxin B1, a major global food safety concern, is produced by toxigenic fungi during crop growing, drying, and storage, and shows increasing annual prevalence. This study aimed to detect aflatoxin B1 in chili samples using ATR–FTIR coupled with machine learning algorithms. We found that 83.6% of the chili powder samples were contaminated with Aspergillus and Penicillium species, with aflatoxin B1 levels ranging from 7.63 to 44.32 µg/kg.

The microbial population in the pig’s gastrointestinal tract can be influenced by incorporating fibrous by-products into the diets. This study investigated the impact of including two types of dried olive cake (OC) in pigs’ diets on fecal bacterial composition. The correlation between fecal microbiota and growth performance, nutrient digestibility, gut fermentation pattern and slurry gas emissions was also evaluated.
