Summary: This study investigated the contamination stage, attachment site, internalization pathway, proliferation process, extracellular substance secretion, and virulence factors expression of L. monocytogenes on iceberg lettuce. The results showed that the contamination stage occurred within 0-20 minutes, followed by proliferation. Attachment was observed in stomata and winkles. L. monocytogenes showed greater internalization distance in the midrib compared to the leaf blade. The up-regulation of flaA and motA genes enhanced cell movement, while the up-regulation of actA and inla genes enhanced adhesion, favoring proliferation. Cells gradually secreted extracellular substances to form biofilms, with a preference for the leaf blade.

Summary: This study aimed to investigate the effectiveness of organic acids and ultrasound in inactivating Escherichia coli and Listeria monocytogenes biofilms on lettuce leaves and examine the impact of these treatments on lettuce quality. The combined treatment of ultrasound and organic acid showed synergistic and antagonistic effects on pathogen biofilms, with a higher anti-biofilm activity compared to single treatments. The type of organic acid and treatment time influenced the biofilm detachment rate, with lactic acid and malic acid exhibiting stronger anti-biofilm activities. Furthermore, the 60-minute decontamination treatments did not adversely affect the color, texture, or sensory quality of the lettuce. Overall, the combined treatment of ultrasound and organic acid is recommended as an effective hurdle technology for removing pathogen biofilms from fresh produce.

Summary: This study identified the acid intolerance phenotype in Listeria monocytogenes strain 1381 and attributed it to a truncation in the mntH gene. The mntH truncation alone, however, could not fully explain the strain's sensitivity to lethal pH. Further experiments revealed that Mn2+ supplementation can rescue the growth of strain 1381 under low pH conditions, indicating that Mn2+ limitation is likely the cause of growth arrest. The importance of strain evaluation and validation in food-related stress conditions was emphasized.

Summary: This study compared different methods to reduce and prevent cross-contamination of Listeria monocytogenes and L. innocua on Fuji apples. The results showed that using a dip procedure with 0.25 ml/dL H2O2-PAA was the most effective in reducing the contamination for both L. monocytogenes and L. innocua. Additionally, using a low pressure, conventional, hand-held garden sprayer with 0.25 ml/dL H2O2-PAA minimized the cross-contamination rate. The study also found that L. innocua is a suitable surrogate for L. monocytogenes on apples.

Summary: This study evaluated the efficacies of chlorine and peroxyacetic acid (PAA) to control Listeria monocytogenes on fresh apples and cross-contamination in simulated dump tank water. The results showed that chlorine and PAA could reduce the number of Listeria monocytogenes, but the efficacy of chlorine was affected by the presence of organic matter, and the antimicrobial efficacy of PAA was concentration dependent. Sanitizers could reduce the transfer of Listeria monocytogenes, but could not eliminate it completely.

Summary: This study simulated and evaluated the formation and transmission of Listeria monocytogenes biofilms on plastic cutting boards. The biofilms were found to mature within 24 hours, with the strongest adhesion. The transfer rates of L. monocytogenes from contaminated cutting boards to cabbage, chicken fillet, and bread were determined during the cutting process. Scrubbing with a commercial dish-washing liquid was effective in reducing microbial concentrations, while tap water rinsing was less effective. The findings highlight the importance of proper cleaning and sanitization of cutting boards.

Summary: This study examined the impact of distance from beef cattle feedlots, environmental factors, and climate on the presence of airborne bacterial indicators and pathogens. Air samples were collected from five feedlots over a 6-month period, and tested for the presence of E. coli O157, non-O157-Shiga toxin-producing E. coli (STEC), Salmonella, and E. coli. Although no bacterial pathogens were detected, E. coli was found in 16.7% of the samples, with a mean concentration of 0.17 CFU/6000 L air. Logistic regression analysis revealed a higher likelihood of E. coli presence in samples closer to the feedlots, as well as associations with meteorological factors and dust-generating activities. This study provides valuable data for future revisions of produce-safety guidance.

Summary: In this study, two bacteriophages, PECP14 and PECP20, infecting Escherichia coli O157:H7 were isolated and found to be stable under different environmental conditions. These phages exhibited specificity in targeting different host receptors and demonstrated the ability to infect other foodborne pathogens. The efficacy of phage treatment was demonstrated through rapid adsorption and bacterial lysis. Furthermore, purified endolysins derived from these phages showed remarkable bacteriolytic activity not only against E. coli O157:H7 but also against other pathogens. These findings suggest that these phages and their endolysins can be used for biological control of E. coli O157:H7 in various stages of agricultural product production.

Summary: The effect of multiple sublethal doses of non-thermal plasma treatments on phenotypical changes and the reduction in phytopathogenicity of three species of fungi was investigated. The plasma damaged the surface of the fungal hyphae, decreased their dry biomass, and affected the activity of pectinase and xylanase. Furthermore, the plasma treatments increased the germination rate of artificially infected cucumber seeds and resulted in plants with higher biomass and longer roots and stems. However, the reduction in phytopathogenicity was not complete after the multiple plasma treatments.
