Salmonella spp. on Chicken Carcasses in Processing Plants in Poland

Abstract

Chickens at selected points in the slaughter process and after slaughter on the dressing line in poultry plants were sampled and analyzed for Salmonella. These chickens came from the northeast part of Poland. The examinations were carried out in quarters I, II, III, and IV of 1999. All the birds were determined to be healthy by a veterinary inspection. Swab samples were taken from the cloaca after stunning and from the skin surface and body cavity of the whole bird after evisceration, after rinsing at the final rinse station but before chilling in the spin-chiller, and after cooling in the continuous cooling plant at the end of the production day. In 1999, 400 whole chickens were examined. The percentage of these 400 chickens from which Salmonella spp. were isolated was relatively high (23.75%; Salmonella-positive results were observed in 95 cases). Salmonella spp. were found after stunning in 6% of the chickens (6 of 100 samples), after evisceration in 24% (24 of 100), before cooling in 52% (52 of 100), and after cooling in 13% (13 of 100). These results show that Salmonella spp. were found more often at some processing points than at others. The lowest Salmonella spp. contamination rate (6%) for slaughter birds was found after stunning, and the highest contamination rate was found before chilling (52%). The serological types of Salmonella spp. isolated from whole chickens were Salmonella Enteritidis, Salmonella Typhimurium, Salmonella Saintpaul, Salmonella Agona, and Salmonella Infantis. The results of these investigations indicate that Salmonella Enteritidis is the dominant serological type in infections of slaughter chickens, as it is in many countries.

Antibiotic resistance and molecular characterization of poultry isolates of Salmonella by RAPD-PCR

“…Poultry products have been implicated as the major source of food borne illness caused by Salmonella sp. in numerous cases (Mikolajczyk and Radkowski 2002).…”

“…Recently, emergence of multiple drug resistant Salmonella has become the cause of great concern all over the world (Mikolajczyk and Radkowski 2002;Carraminana et al 2004;Fluit 2005). Antibiotic resistance studies in Salmonella have mostly been confined to clinical isolates (Soto et al 2003) and relatively fewer reports are available on antibiotic profiling of Salmonella isolates from different food types (Bajaj et al 2003b;Carraminana et al 2004;Mrema et al 2006).…”

Occurrence of Salmonella spp. in broiler chicken carcasses and their susceptibility to antimicrobial agents

“…The occurrence of Salmonella in chicken carcasses, in studies undertaken in different countries, can vary for instance from 13% in Poland (21) to 66% in Thailand (17). In Brazilian studies, they vary from 5.9% (20) to 42% (14).…”

Ocorrência de Salmonella spp. em carcaças de frangos recém abatidos em feiras e mercados da cidade de Manaus-AM

“…Em estudo realizado na Bélgica Uyttendaele et al (1999), analisando 772 carcaças de frango, constataram a contaminação de Salmonella spp em 36,5% das amostras. Na Polônia, Mikolajczyk & Radkowski, (2002), ao estudarem 4 diferentes etapas de processamento de carcaças de frango encontraram uma porcentagem alta de resultados positivos para Salmonella spp, de 400 amostras observaram 23,7% de positividade, distribuídos nos processos de abate, pós evisceração, pré e pós resfriamento, sendo os tipos isolados S. enteritidis, S. typhimurium, S. saintpaul, S. agona e S. infantis, sendo a S. enteritidis o sorotipo mais dominante.…”
