Summary: Most Campylobacter infections in humans are sporadic cases connected to private households. Chicken meat, believed to be the main source of human exposure, poses cross-contamination risks in the kitchen. Freezing can reduce Campylobacter concentrations on chicken meat. Different Campylobacter sequence types have varying abilities to withstand freezing stress. Campylobacter remaining on hands after washing and on cutting boards after wiping are likely sources of cross-contamination in the kitchen.

Summary: A simple saltatory rolling circle amplification (SRCA) assay has been developed for rapid and accurate detection of Campylobacter jejuni in chicken meat. The specificity and sensitivity of the assay have been validated, showing 10- and 100-fold better detection limits compared to end-point and real-time PCR, respectively. This method is suitable for resource-limited food analysis laboratories.

Summary: The study shows that Campylobacter jejuni spreads through contaminated poultry products, and an attenuated Escherichia coli live vaccine strain expressing the C. jejuni N-glycan can reduce the Campylobacter load in poultry, with distinct responder and non-responder outcomes. Research indicates that antibodies from responder birds have higher Campylobacter-opsonophagocytic activity, and transplantation of cecal microbiota from responder birds can enhance vaccine-induced antigen-specific IgY responses.

Summary: Isothermal amplification (IA) is a nucleic acid amplification technology that has significantly contributed to the healthcare system by improving disease diagnosis through higher sensitivity, specificity, and rapidity. Certain IA techniques provide a rapid, sensitive, specific, and simple method for disease diagnosis. However, not all IA techniques have been widely used in clinical applications due to the influence of different biomarkers and sample types on the IA system.

Summary: This study aimed to determine the microbial kinetic parameters in chicken under dynamic temperature for campylobacteriosis strains in New Zealand. The obtained D and z values were consistent with international isothermal data, indicating that the high rate of campylobacteriosis in New Zealand is not due to the emergence of more heat resistant strains.

Summary: Poultry is a rapidly growing industry, but concerns about food safety and the presence of bacteria like Campylobacter in poultry remain. The discovery of new antimicrobials, such as eugenol, is important for ensuring the safety of poultry meat. However, further research is needed to determine the specific applications and effectiveness of eugenol as a food preservative in poultry meat safety.

Summary: This cross-sectional study in Zambia discovered the transmission of antimicrobial resistance among Escherichia coli and other enterobacteria isolated from healthy wildlife and livestock cohabiting in a game ranch near Lusaka. The study highlights the need for further investigation on the role of wildlife in the development and transmission of antimicrobial resistance, a global concern.

Summary: The study investigated the presence of SARS-CoV-2 in cultivated oysters sold in Japan and evaluated the risk of food-borne transmission. The results indicated that consumption of oysters cultivated in coastal areas may not be a risk factor for SARS-CoV-2 outbreaks, suggesting that well-developed sewage treatment facilities contribute to preventing viral contamination.

Summary: The lack of practical testing methods for African swine fever (ASF) has hindered early detection and early containment of the pandemic. In this study, a rapid and sensitive point-of-care test (POCT) was developed to detect ASF using swine whole blood samples. The POCT enabled crude DNA to be extracted from swine whole blood samples within 10 min at low cost and with ease. Compared to conventional real-time PCR detection, the POCT showed slightly lower sensitivity but comparable diagnostic accuracy. It is expected that this POCT will facilitate early diagnosis and containment of ASF.
