Comparing methods for catching and crating broiler chicken flocks: A trade-off between animal welfare, ergonomics and economics.

Catching, carrying, and loading of broilers before transport to the slaughterhouse causes stress. In this study three catching methods (two manual (inverted, upright) and one mechanical) were compared using a cost-benefit analysis of animal welfare, ergonomics and economic analysis. Depopulation of approximately 5,000 broilers per catching method per flock (upright vs.

Survey of Flemish Poultry Farmers on How Birds Fit for Transport to the Slaughterhouse Are Selected, Caught, and Crated and Their Opinions Regarding the Pre-Transport Process.

The pre-transport phase induces stress, fear, and injury in poultry, but management choices greatly influence this. Pre-transport practices for spent hens and broilers in Flanders (Belgium) were studied. Poultry farmers (31 of 156 layers and 48 of 203 broiler farmers completed the survey) were surveyed on the selection of unfit chickens, catching and crating, and farmer opinion.

Upright versus inverted catching and crating end-of-lay hens: a trade-off between animal welfare, ergonomic and financial concerns.

This study explores upright versus inverted catching and crating of spent laying hens. Both catching methods were compared using a cost-benefit analysis that focused on animal welfare, ergonomic, and financial considerations. Data were collected on seven commercial farms (one floor system and six aviary systems) during depopulation of approximately 3,000 hens per method per flock.

Intra- and inter-batch variability in raw pork challenge test studies and their consequences on model predictions: An intricate interplay between L. monocytogenes, the microbiome, and packaging atmosphere.

The purpose of this study was to conduct challenge studies in raw pork by strictly following all aspects of the 2014 EURL technical guidance document for conducting shelf-life studies on Listeria monocytogenes. Growth potential was assessed on three batches of self-cut pork chops and one batch of in-house prepared pure minced pork without any additives in air and MAP (70 % O/30% CO) packaging. Pork chops did not support the growth of the pathogen throughout the shelf-life, given the specific conditions used in this study, with growth potential values of 0.

Genetic Types in the Pork Processing Plant Environment: From Occasional Introduction to Plausible Persistence in Harborage Sites.

The purpose of this study was to investigate the occurrence and genetic diversity in three Belgian pork cutting plants. We specifically aim to identify harborage sites and niche locations where this pathogen might occur. A total of 868 samples were taken from a large diversity of food and non-food contact surfaces after cleaning and disinfection (C&D) and during processing.

Study of the transfer of Listeria monocytogenes during the slaughter of cattle using molecular typing.

The introduction, transmission, and persistence of Listeria monocytogenes in Belgian beef slaughterhouses was investigated using genetic characterization. During slaughter, samples were taken of the hide, carcass, and environment to detect the pathogen. Remarkably, L.
