A major health and financial burden in the chicken sector is salmonella infection. It is difficult to create an oral vaccination that can provide strong intestinal mucosal immunity in birds, particularly cross-protection against several Salmonella serotypes. As a result, the poultry industry needs a powerful oral vaccination platform that uses live bacterial vectors to prevent various Salmonella serotypes.

Due to an increased demand for natural food additives, clove oil was assessed as a natural alternative to chemical disinfectants in produce washing. This study assessed the antimicrobial activity of 5 and 10% (/) clove oil-amended wash liquid (CO) using a zone of inhibition (ZIB) test and determined the time required to completely inactivate pathogenic bacteria using bacterial death curve analysis. A washing experiment was used to evaluate CO's ability to inhibit bacterial growth on inoculated RTE spinach and in the wash water.

Slaughterhouse environments are prone to microbial contamination, influenced by factors like set-up, size and area as well as disinfection practices. Thus, effective control measures are crucial to prevent the spread of pathogens and their contaminant genes (antimicrobial resistance genes and virulence factors) throughout the food chain. In the present study, we assessed the microbial contamination in environmental surfaces of three slaughterhouses located in the Jaén province (Spain).

The discovery at the end of the 20th century of genes that induce cell death revolutionised the biocontaintment of genetically manipulated bacteria for environmental or agricultural applications. These bacterial 'killer' genes were then assayed for their potential to target and control malignant cells in human cancers. The identification of the bacteriomes in different human organs and tissues, coupled with the observation that bacteria tend to accumulate near tumours, has opened new avenues for anti-cancer strategies.
