Sources of poultry meat contamination with thermophilic Campylobacter before slaughter BJM
Franchin,Paulo Rogério; Aidoo,Kofi E.; Batista,Cleide Rosana Vieira.
The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system in southern Brazil. The study was carried out over a 12-month period, and each broiler house was sampled in three consecutive flocks, for a total of 24 flocks/broiler house. Campylobacter was found in 79.2% of the feather samples, followed by cloacal swabs (75.0%) and transport coop (50.0%), litter (37.5%), breast support (33.3%) and coop rinse water (25.0%) samples....

Experimental results and modeling of poultry carcass cooling by water immersion Ciênc. Tecnol. Aliment.
Carciofi,Bruno Augusto Mattar; Laurindo,João Borges.
Poultry carcasses have to be chilled to reduce the central breast temperatures from approximately 40 to 4 °C, which is crucial to ensure safe products. This work investigated the cooling of poultry carcasses by water immersion. Poultry carcasses were taken directly from an industrial processing plant and cooled in a pilot chiller, which was built to investigate the influence of the method and the water stirring intensity on the carcasses cooling. A simplified empiric mathematical model was used to represent the experimental results. These results indicated clearly that the understanding and quantification of heat transfer between the carcass and the cooling water is crucial to improve processes and equipment. The proposed mathematical model is a useful...

Rational use of water in a poultry slaughterhouse in the state of Paraná, Brazil: a case study REA
Barana,Ana C.; Botelho,Viviani M. B.; Wiecheteck,Giovana K.; Doll,Maria M. R.; Simões,Deise R. S..
Agroindustries are major consumers of water. However, to adapt to environmental trends and be competitive in the market, they have sought rational use of water through water management in their activities. Cleaner Production can result in economic, environmental and social benefits, and in actions that promote reduction in water consumption. This case study was conducted in a slaughterhouse and poultry cold storage processing plant and aimed to identify points of excessive water consumption, and to propose alternatives for managing water resources by reducing consumption. Consumption data are presented in relation to the processing stages with alternatives proposed for the rational use of water, such as closure of mains water during shift changes....
