After harvesting, pathogens can infect fresh vegetables in different ways. Pathogenic bacteria associated with fresh vegetables can cause widespread epidemics associated with foodborne illness. The aim of this study was to assess the microbiological quality of carrot slices after treatment with aqueous extracts of (AE) at different concentrations AE1 (10 mg/mL), AE2 (5 mg/mL), AE3 (2.5 mg/mL) and AE4 (1.25 mg/mL), and subsp. serovar Enteritidis, along with vacuum packaging and storage of carrots for 7 days at 4 °C. On days 1. and 7., total viable counts (TVC), and coliforms bacteria (CB), and count were all analysed. Microorganisms that were obtained from carrots were identified using MALDI-TOF MS Biotyper Mass Spectrometry. The total viable, coliform bacteria and counts were varied by the group of treatment. Higher counts were found in the control group on both days. The most isolated species of bacteria were and on the 1. day and on the 7. day. The current study adds useful information for a better understanding of how reacts to the effect of AE and its potential use as a sustainable washing method to eliminate bacteria from freshly cut carrots.

Background: As a leading cause of foodborne illness worldwide, detection of Salmonella enterica subsp. enterica serovar Typhimurium is essential for food safety and public health.
Objective: This study aimed to develop a loop-mediated isothermal amplification (LAMP) assay for the rapid and sensitive detection of Salmonella ser.

Enteric pathogens engage in complex interactions with the host and the resident microbiota to establish gut colonization. Although mechanistic interactions between enteric pathogens and bacterial commensals have been extensively studied, whether and how commensal fungi affect enteric infections remain largely unknown. Here we show that colonization with the common human gut commensal fungus Candida albicans worsened infections with the enteric pathogen Salmonella enterica subsp.

Inducing inflammation in response to pathogen infection is known to be an energy-intensive process. An extended state of inflammation in production animals can be detrimental to performance parameters. Here, we compare two doses of a microencapsulated thymol-based feed additive blend and two different antibiotics in the context of a Salmonella Enterica subsp.

The growing demand for natural preservatives has driven interest in essential oils (EOs) from medicinal and aromatic plants. This study examines the potential of EOs from six wild populations of Albanian , specifically subsp. , , and species, to be utilized for food conservation, among other possible uses.

This study aimed to develop innovative functional gummy candies enriched with protein hydrolysates derived from porcine liver, enhancing their antioxidant and antimicrobial properties. First, the overall consumer acceptability (OA) was assessed to determine the most suitable combination of gummy matrix components. Selected combinations were then analyzed for antioxidant activity (ABTS•+, DPPH•), antimicrobial effects, microbiological safety, and physicochemical characteristics.
