Nelson Cox United States Department of Agriculture, Agriculture Research Service, Russell Research Center, Athens, Ga.From the AuthorFood SafetyControlling Listeria in hatcheries and plantsListeria is rare on the farm, but when it enters the processing plant it can potentially contaminate equipment and other birds.Food SafetyUsing new technology to detect Salmonella on broilersPoultry is a major Salmonella reservoir, but conventional culture-based methods usually only identify the most abundant serovars while those less abundant go undetected.Broilers & TurkeysChemical treatments to control Campylobacter on thighsScientists have determined a multi-hurdle approach is necessary for adequate pathogen reduction.Processing & SlaughterReducing contamination of carcasses during defeatheringApplying an acidic solution to the cloaca of broiler carcasses before picking can significantly reduce Campylobacter contamination, according to a recent study by the U.S. Department of Agriculture Agricultural Research Service.Processing & SlaughterHow picking increases Campylobacter in processingCampylobacter bacteria counts increase after feather picking. This could be coming from contaminated machines, airborne contaminants or cecal discharges.Broilers & TurkeysSalmonella, Campylobacter infection routes in broilersDay-old broiler chicks can be exposed to, and colonized, by pathogenic bacteria through a number of routes. This must be prevented to protect food safety.Broilers & TurkeysWashing broiler transport cages - if not, why not?Campylobacter and Salmonella are leading causes of human bacterial foodborne disease. What is the role of the transport coops in spreading this contamination in broiler chickens?Processing & SlaughterDrying broiler transport cages reduces CampylobacterBroiler transport cage drying and the application of a dry treatment (absorbent cornstarch powder) have been shown in poultry research to diminish the foodborne pathogen Campylobacter on transport cages.Processing & SlaughterBetter Campylobacter detection needed to protect chicksCampylobacter cultivation and detection methods to recover injured or stressed cells need to be greatly improved to allow for the development and implementation of more effective intervention strategies. Poultry scientists should question laboratory results and adopt new methods in order to obtain a better understanding of this elusive organism.Processing & SlaughterIsolation of Campylobacter from the circulating blood of broilersFrom a poultry processing viewpoint, Campylobacter presence in circulating blood of market-age broilers may increase the likelihood of cross-contamination between birds during slaughter.Broilers & TurkeysDoes Salmonella translocate in organs to colonize broiler chicks?Studyshows the translocation of Salmonellatyphimurium to the thymus, liver/gallbladder and spleen following oral andintracloacal inoculation of day-old chicks.Processing & SlaughterComparison of US and EU Salmonella detection methodsMethods to sample processed broiler carcasses for the presence of Salmonella can differ among countries. Neck-skin excision and whole-carcass rinsing are differing methods used to detect Salmonella prevalence on commercial broiler carcasses before and after chilling.Page 1 of 2Next Page
