This study aimed to evaluate the antimicrobial and antibiofilm activities of black pepper essential oil (BPEO) and piperine and the effect of piperine on gene expression in a multispecies biofilm composed of Listeria monocytogenes, Salmonella Typhimurium, and Pseudomonas aeruginosa on a polypropylene surface. The minimal inhibitory concentrations of BPEO and piperine were 100 and 25 mg/mL, respectively, against this consortium of microorganisms.

Thermal-death-time characteristics, D- and z-values of shiga toxin-producing Escherichia coli (STEC), Salmonella, and Enterococcus faecium NRRL B-2354 were investigated in peanut butter, oatmeal, and chocolate chip cookie formulations at three moisture levels. E. faecium was shown to be more resistant than Salmonella, followed by E. coli at all water activity levels. E.

This study evaluated the combined antibacterial effect of 460 nm LED illumination and chitosan on Escherichia coli O157:H7, Salmonella spp. and Listeria monocytogenes on fresh-cut melon surface and its impact on the quality of melon at a total dose of 2.4 kJ/cm2 at 4 and 10 °C.

Colorimetry has emerged as a promising option for pathogenic detection. Herein, a novel method based on saltatory rolling circle amplification (SRCA) combined with photosensitization colorimetric assay (SRCA-C) was developed for rapid and sensitive detection of Salmonella in food. The target identification and signal amplification are realized by SRCA to produce a large amount of double-stranded DNA.

Onions are always in high demand owing to various culinary as well as health protective properties and these days there is increased consumer preference for ready-to-eat or ready-to-cook onions. In this context, the current study was aimed to extend the keeping quality of minimally processed onions for an extended period while ensuring microbial safety as well as sprouting inhibition through an integrated approach.

The FDA Bacteriological Analytical Manual (BAM) Salmonella culture method takes at least 3 days for a presumptive positive result. The FDA developed a quantitative PCR (qPCR) method to detect Salmonella from 24-h preenriched cultures, using ABI 7500 PCR system. The qPCR method has been evaluated as a rapid screening method for a broad range of foods by single laboratory validation (SLV) studies.

The aim of this study was to determine the growth potential (δ) of Salmonella enterica in various parts (peel, stalk, pulp, and tip) of avocado and sugar apple at different maturation stages (green, mature, and ripe) over time. In addition, physicochemical parameters of the fruits were monitored using standard methods. There were statistically significant differences in the growth potential of S.

The objective of this study was to examine the frequency and extent of antibiotic-resistant pathogens in seafood sold in Malaysia, using a systematic review and meta-analysis approach to analyze primary research studies. Four bibliographic databases were systematically searched for primary studies on occurrence. Meta-analysis using a random-effect model was used to understand the prevalence of antibiotic-resistant bacteria in retail seafood sold in Malaysia.

Salmonella is a poultry-associated pathogen that is considered one of the most important zoonotic bacterial agents of contaminated food of animal origin including poultry products. Many efforts are taken to eliminate it from the food chain, and phages are one of the most promising tools to control Salmonella in poultry production. We investigated the usefulness of the UPWr_S134 phage cocktail in reducing Salmonella in broiler chickens.

Salmonella is a food-borne pathogen often linked to poultry sources, causing gastrointestinal infections in humans, with the numbers of multidrug resistant (MDR) isolates increasing globally.

Pork substantially contributes to salmonellosis, and processors are increasingly interested in antimicrobials. This study applied antimicrobials using commercial equipment and parameters to reduce Salmonella in pork. Skin-on carcasses inoculated with a Salmonella cocktail (ca.

The demand for rapid and accurate detection methods for Salmonella Enteritidis necessitates the development of highly sensitive and specific biosensors to ensure proper monitoring of food safety and quality requirements in the food sector and to secure human health. This study focused on development of a polyaniline/zinc oxide (PANI/ZnO) nanocomposite film on a gold electrode conductometric immunosensor for detection of Salmonella Enteritidis.

Background Antimicrobial resistance is a serious threat to public health globally. It is a slower-moving pandemic than COVID-19, so we are fast running out of treatment options. Purpose Thus, this study was designed to search for an alternative biomaterial with broad-spectrum activity for the treatment of multidrug-resistant (MDR) bacterial and fungal pathogen-related infections. 

During the slaughtering process, the meat product cross-contaminates with the surrounding contact surfaces. This study aimed to assess the level of microbial contamination of poultry chicken meat and contact surfaces at poultry slaughterhouses in the Hyderabad and Jamshoro districts of Pakistan. A total of 38 slaughter shops were selected, and from each shop, three types of samples were collected.

Food hygiene is important both for its impact on the health of citizens and also for the cost of the infections that it can generate. In Morocco, it has become a concern of authorities.
