Unlabelled: are Gram-negative, rod-shaped, entero-invasive foodborne bacteria and are frequently detected in chicken houses and facilities of poultry broiler complexes. The objective of this study was to determine the prevalence, critical entry points, and movement pattern of along different stages of a complex. A total of 1,071 environmental samples were collected from 38 production houses (8 pullet, 10 breeder, and 20 broiler), a hatchery, 6 transport trucks, and a processing plant.

infections in poultry production are a significant and pervasive concern, posing substantial risks to both animal and human health. This comprehensive literature review examines the current body of research on the use of various nutritional manipulations as a promising strategy to effectively control and mitigate the prevalence of in poultry. The review covers a range of dietary interventions, particularly the utilization of probiotics, prebiotics, organic acids, and phytochemicals, and thoroughly evaluates their efficacy in reducing colonization within poultry flocks.

Poultry processing wastewater (PPW) is a nutrient-rich effluent with the potential for reuse in crop irrigation. This study investigated transforming PPW into a hydroponic nutrient solution using a pilot scale "poultryponics" system operated continuously for 222 days. The system treated ∼57 L d of real PPW and consisted of bioreactors (inoculated with a consortium of microalgae and nitrifying bacteria), clarifiers, membrane filters, a UV disinfection unit, and a deep-water hydroponic system.
