“…It is mentioned that Salmonella contamination form the environment in to the flock can be the major sources of highest prevalence and same with the environmental transmission, faeces is one of the most important risk factor for Salmonella contamination in pens. It is also accepted that elimination of Salmonella from the environmental samples would reduce the contamination rate of table eggs [25,26]. As a predominant serotype S. Kentucky was detected in all of the sample matrices collected from laying hens except for feed samples.…”

Foodborne infections due to Salmonella are still a major concern worldwide. Particularly contaminated egg and egg related products are the primary sources for human salmonellosis. It is necessary to determine the risk factors associated with Salmonella contamination of eggs within the scope of farm to table and environment. The objective of this study was to develop the "National Salmonella Control Program in Laying Hens" and report the prevalence and serotype distribution findings of Salmonella in laying hens and eggs in Turkey. A total of 2122 samples were collected and analysed according to ISO 6579:2002 after the isolation and identification procedures. All Salmonella isolates were serotyped including 726 eggs and 1396 farm specimens from 241 epidemiological units (EpUs) that were located in 9 different provinces between 2015 and 2017. Salmonella contamination was detected in 14.9% of 241 EpUs. The results indicated that almost half of the flocks have multiple contamination sources. The highest contamination rate was obtained from environmental (11%) followed by faeces (7.5%) and the lowest was from water samples (1.6%). The overall contamination rate was detected as 7.46% for farms and 3.3% for eggs. As S. Enteritidis and S. Typhimurium are the most frequently seen serotypes all over the world, in Turkey S. Typhimurium was not detected and S. Enteritidis was the 5th most common isolated serotype. According to our results it can be concluded that differences in various countries, particularly geographical and egg hatching systems, may affect the contamination rate and serotype distribution of Salmonella.

“…Doenças como salmoneloses, Influenza Aviária e Doença de Newcastle, possuem alto risco de disseminação pelo trânsito. Além do trânsito de aves, o de materiais contaminados pode levar à disseminação de doenças às criações comerciais (Terregino et al, 2007;Kaleta & Rülke, 2008;Rajan et al, 2016).…”

RESUMO.A movimentação animal é um dos principais meios de disseminação de doenças. Muitas destas, pelos riscos e impactos na cadeia produtiva, fazem parte de programas de controle do Serviço de Defesa Sanitária Oficial de cada país. Com o intuito de evitar a dispersão de agentes patogênicos no Brasil, diretrizes para este controle são determinadas pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA) e executadas, em Santa Catarina, pela Companhia Integrada de Desenvolvimento Agrícola de Santa Catarina (CIDASC). O objetivo deste trabalho foi analisar e divulgar dados referentes à movimentação de aves oriundas de produções comerciais de Santa Catarina, considerando o trânsito intra e interestadual ocorrido durante o ano de 2017. Para tal, informações referentes a este período foram obtidas no banco de dados da CIDASC. Os resultados demonstraram que foram movimentados, em média por mês, no trânsito intraestadual, no período avaliado, 136.210.943 aves, sendo 72.919.263 para abate, 62.710.860 para engorda e 580.820 para reprodução. Os municípios catarinenses que mais movimentaram aves (origem) foram Videira, Herval d`Oeste, Faxinal dos Guedes, Chapecó e Araranguá, e os municípios que mais receberam aves (destino) foram Capinzal, Videira, Concórdia, Chapecó e Seara. Análises referentes ao trânsito interestadual demonstraram que foram movimentados mensalmente, para fora de Santa Catarina, em média, no período avaliado, 20.514.668 aves, sendo 1.641.304 para abate, 18.841.244 para engorda e 32.120 para reprodução. Os principais destinos das aves catarinenses são Paraná, Rio Grande do Sul e São Paulo. Nossos resultados demonstram a importância da avicultura na região Oeste do Estado e a ocorrência de um intenso trânsito de aves no Estado, sendo o transporte intraestadual responsável por 90,74% desta movimentação. Devido aos riscos sanitários que o transporte de animais representa, esforços para o controle deste transporte devem ser continuamente realizados.

“…While various food sources, including pork, beef, and fresh produce, have been implicated in Salmonella outbreaks, these infections are often associated with the consumption of raw or undercooked poultry products [ 3 , 6 ]. In fact more than 70% of human Salmonellosis in the US are attributed to the consumption of contaminated poultry meat and eggs [ 5 ].…”

“…This link between zoonotic foodborne infection and poultry products is concerning given the tremendous increase in the demand for poultry meat and eggs. It is estimated that people consume approximately 250 eggs per year and that poultry meat constitutes almost 50% of the annual per capita consumption of meat in the US [ 6 , 7 ]. Therefore, the microbiological safety of poultry products is a major concern from public health and economic perspectives [ 8 ].…”

Salmonella Enteritidis (SE), Salmonella Typhimurium (ST), and Salmonella Heidelberg (SH) have been responsible for numerous outbreaks associated with the consumption of poultry meat and eggs. Salmonella colonization in chicken is characterized by initial attachment to the cecal epithelial cells (CEC) followed by dissemination to the liver, spleen, and oviduct. Since cecal colonization is critical to Salmonella transmission along the food chain continuum, reducing this intestinal association could potentially decrease poultry meat and egg contamination. Hence, this study investigated the efficacy of Lactobacillus delbreuckii sub species bulgaricus (NRRL B548; LD), Lactobacillus paracasei (DUP-13076; LP), and Lactobacillus rhamnosus (NRRL B442; LR) in reducing SE, ST, and SH colonization in CEC and survival in chicken macrophages. Additionally, their effect on expression of Salmonella virulence genes essential for cecal colonization and survival in macrophages was evaluated. All three probiotics significantly reduced Salmonella adhesion and invasion in CEC and survival in chicken macrophages (p < 0.05). Further, the probiotic treatment led to a significant reduction in Salmonella virulence gene expression (p < 0.05). Results of the study indicate that LD, LP, and LR could potentially be used to control SE, ST, and SH colonization in chicken. However, these observations warrant further in vivo validation.
