Levantamento de salmonella spp. em carcaças de frango provenientes de matadouros avícolas sob o serviço de inspeção estadual no Estado da Bahia, Brasil

Abstract

Caused by S. Pullorum, the pullorum disease can affect birds at any age, but it is the young people that the disease has a high mortality (BARROW; FREITAS NETO, 2011). Clinical signs in chickens include anorexia, bacillary white diarrhea, dehydration, weakness and death, decreased egg production and hatchability (OIE, 2012). Chickens are the natural hosts of S. Gallinarum typhus agent aviary can affect birds of any age is characterized by causing sepsis and toxemia. The birds are quiet, prostrate, lie down, do not eat, present yellow-green greenish diarrhea, there is egg drop and in a few days can get to death. Morbidity and mortality can be high (Berchieri JR; FREITAS NETO, 2013). The most common agent in paratyphoid is the S. Typhimurium. Young birds are more susceptible. Those salmonella are not specific to chickens, but adapt very well to the intestinal tract of chicken and turkey and may persist in the enteric tract and are shed in the stool for several weeks and can invade the bloodstream and spread to various organs such as ovaries, spleen, liver and heart (MACARI; MAIORKA, 2000). Researched the occurrence of Salmonella spp. in broiler carcasses slaughtered and marketed in municipalities in the Reconcavo region of Bahia state in order to contribute to the generation of data for the production chain of poultry meat and supervisory bodies that monitor the risk to public health. Of the 224 samples of chicken carcasses examined, 113 suggestive grown in selective medium for the isolation of Salmonella spp. or 50.44 %% of the samples. Of the 27 isolates (42.20%) 64-intestinal samples analyzed were found the same result. Similar findings were reported in 43 (55%) of the 78 liver samples analyzed, 43 (52.4%) of the 82 lung samples. Denotes that the frequency of findings is likely to lead to losses for the poultry industry and public health.
