Summary: Bacteriophages can be evolved to have improved abilities to control specific foodborne pathogens. In this study, researchers selected for mutant phages with improved infection kinetics in whole milk through experimental evolution. They identified two gene mutations that affected the surface charge of proteins and demonstrated that the fat content in milk is crucial for the expression of this phenotype. The findings highlight the potential of experimental evolution in developing condition-specific phage-based biocontrols in the food industry.

Summary: This study explores the self-applicability of a new sleep EEG sensor array and finds that it can be used by healthy participants without prior training. The results show that the signal quality of the new array is comparable to that of a traditional PSG system, and there is a substantial agreement between the two systems in terms of hypnogram annotations. This flexible sensor array provides convenience for self-recording sleep EEG at home.

Summary: This review investigates the occurrence and impact of antibiotics in the environment, with particular focus on the interaction between antibiotics and humic substances (HS) and their influence on the dissemination of antibiotic-resistance genes. Quantitative data and proposed mechanisms of antibiotic-HS interaction are provided, along with discussions on the challenges of quantifying this interaction. Successful examples of using humic-based sorbents for antibiotic removal from water systems are given. The review also summarizes the various effects of HS on the dissemination of antibiotic-resistance genes and suggests the importance of characterizing HS properties for assessing the environmental consequences of antibiotic-HS complex formation.

Summary: Food processors face challenges in dealing with Listeria monocytogenes in production and processing facilities. This study analyzed environmental monitoring data from the frozen food manufacturing industry to evaluate current practices in mitigating risks and identify trends for improvement. The findings suggest that certain areas and storage locations have a higher probability of Listeria contamination, providing guidance for sanitation measures in processing operations.

Summary: Researchers developed a novel ultrasensitive and selective MPSE NO2 sensor based on K2Fe4O7 solid electrolyte and Ni-MOF|N2 sensing electrode. The sensor can achieve a low detection limit of 5 ppb at room temperature without additional energy supply. It can also be used as an information collection terminal for IoT systems, enabling remote monitoring, environment evaluation, and information sharing.

Summary: Food safety and quality can be affected by microbiological contamination, and monitoring both food products and production environment through Environmental Monitoring Programs (EMPs) is crucial. Despite available literature, there is no standard method for constructing EMPs, which need to be dynamic and regularly updated to ensure their effectiveness. An EMP typically includes pre-analytical, analytical, and post-analytical steps to design, sample, and manage data for microbial controls in food processing plants.

Summary: The study demonstrated that phages could significantly reduce the number of E. coli O177 bacteria on the surface of beef, with some phage cocktails showing better efficacy. This suggests that phage cocktails may be used to reduce E. coli O177 contamination and extend the shelf-life of raw beef.

Summary: Environmental monitoring programs (EMP) are essential for ensuring food safety, but knowledge about monitoring practices is not widely disseminated. This survey collected information on monitoring practices in the French agri-food industry and found that EMP strategies are based on risk management. The lack of guidance and the need to balance standardization with site-specific characteristics were identified as challenges.
