Article Abstract
Bacterial foodborne disease outbreaks (FBDOs) pose significant public health risks. This study aimed to assess the risk of food-pathogen combinations in bacterial FBDOs in Zhejiang Province using Disability-Adjusted Life Years (DALYs) to inform targeted prevention and control strategies. Data from the Foodborne Disease Outbreak Surveillance System (FDOSS) between 2010 and 2022 were analyzed, focusing on outbreaks with identified food-pathogen combinations. DALYs were calculated for bacterial FBDOs and specific food-pathogen pairs. Over the 13-year period, 405 bacterial FBDOs involving 118 distinct food-pathogen combinations were reported, resulting in 112.32 (95 % CI: 110.42-114.51) DALYs. The top ten food-pathogen combinations, associated with 161 outbreaks, accounted for 110.36 (95 % CI: 109.22-111.71) DALYs. The DALYs caused by the same or different food-pathogen combination FBDOs varied across different outbreak settings. By integrating outbreak case numbers (representing risk likelihood) and DALYs (representing risk severity), this study identified high-priority food-pathogen combinations and their predominant outbreak settings. This study provides a relative risk basis for regulatory priority ranking, which will help prevent and reduce the occurrence of certain food-borne pathogen outbreaks.

Background: Phage therapy, a treatment utilizing bacteriophages to combat bacterial infections, is gaining attention as a promising alternative to antibiotics, particularly for managing antibiotic-resistant bacteria. This study aims to provide a comprehensive review of phage therapy by examining its safety, efficacy, influencing factors, future prospects, and regulatory considerations. The study also seeks to identify strategies for optimizing its application and to propose a systematic framework for its clinical implementation.

Short-chain carboxylic acids (SCCAs) that are naturally produced by microbial fermentation play an essential role in delaying microbial spoilage. SCCAs are structurally diverse, but only a few of them are routinely used in food biopreservation. This study investigated the effects of environmental pH and intrinsic properties of 21 structurally different SCCAs on the antimicrobial and antibiofilm activity against .

The use of natural and sustainable additives, that are less aggressive to the environment, is a trend in the food industry. Rhamnolipids (RL) biosurfactants have shown potential for controlling food pathogens however, due to the presence of free carboxyl groups, the pH and ionic strength may influence the properties of such surfactants. In this study, we describe the antimicrobial activity of RL under different pH values and NaCl concentrations, towards both planktonic and biofilms of Listeria monocytogenes.
