Listeria monocytogenes, E. coli O157, Salmonella spp. e microrganismos indicadores em carcaças bovinas para exportação

Samples were collected from 100 carcasses in a slaughterhouse exporter, located within the State of São Paulo, sampled over a year through the sponge method, applied to the chest of the animal. Samples were taken at three points, denominated A, B and C, each carcass sampled at three points located in the following steps: after bleeding (A) after skinning (B) and after washing (C). Research was conducted for Listeria sp., E. coli O157, Salmonella spp. and Micro-organism (Petrifilms ® AC, EC and EB). Listeria or E. coli O157 were not isolated in any of the 300 samples. Salmonella spp. was isolated in nine, eight at point A and one at point B. For Mesophiles, scores ranged from 0 to 6.8 log UFC/cm²; for Total coliforms, 0 to 4.57 log UFC/cm² and E. coli from 0 to 4.38 log UFC/cm². With the results obtained and compared with the literature, it is concluded that the establishment in this study has both sanitary quality (due to the low prevalence of pathogens) and hygienic quality (due to the sharp decrease in the microbial load of indicators along the line.

O uso de ducha: efeito sobre o bem-estar e a qualidade da carcaça e da carne em suínos transportados para o abate

This study was carried out to evaluate the effects of a shower before and after pig transportation on welfare, meat and carcass quality. We used 384 crossbreeding animals (females and castrated males), from 16 farms in Santa Catarina State, Brazil. A 2x4 factorial arrangement of treatments was employed with two distances from farm to slaughter plant (less than 50km and more than 50km) and four showering protocols. These protocols were applied on pigs: no showering at farm or slaughter plant (Control), no showering at farm but showering at the plant (NMG_MOF); showering at the farm and no showering at the plant (MOG_NMF); showering at the farm and plant (MOG_MOF). None of the factors influenced (P>0.05) physiological variables related to stress (cortisol and lactate in blood samples), number of carcass lesions and the characteristics of meat quality.

Prevalência, distribuição espacial e fatores de risco para cisticercose bovina no estado de São Paulo

This study aimed to determine the prevalence and geographical distribution as well as the factors and areas of risk associated with bovine cysticercosis in the State of Sao Paulo. 34.443 cattle, males and females with ages from 18 to 60 months were inspected. The animals were from 97 cities in the state of Sao Paulo and identified and slaughtered in the period October 2010 to August 2011, in a refrigerator located in Ipua - SP, under the supervision of SIF 1387. The state of Sao Paulo was divided into regional centers, and the data of the municipalities belonging to its core, were grouped according to the Department of Agriculture and Food Supply of Sao Paulo, totaling 13 cores studied. Based on these results, we can conclude that of the 97 cities analyzed, cattle were found positive for the disease in 86. The average prevalence of bovine cysticercosis in the state of Sao Paulo was 4.80 %, while the core inflation Franca and Barretos were the ones with the highest number of cases illness during the analysis period. Moreover, the largest number of cases in these core coincided with the lowest human development index covering education, with the largest acreage of coffee (core Franca) and also as the largest area of cane sugar grown (core Barretos) in these locations, which in turn may indicate that the presence of labor, temporary labor in rural areas, combined with socioeconomic/cultural factors might contribute to the spread and establishment of bovine cysticercosis in these areas.

Caracterização histomorfológica de lesões granulomatosas sugestivas de tuberculose ganglionar e pulmonar em bovinos abatidos na região noroeste do estado de SãoPaulo

Tuberculosis infection among humans transmitted by products of animal origin can be caused by Mycobacterium bovis, a concern in developing countries, because the number of human cases is relatively high compared with countries that have implemented programs to eradicate bovine tuberculosis for many years. Because it is a chronic disease with subclinical evolution, it is transmitted to other animals in the herd livestock resulting in high loss losses resulting high (10 to 25%), as well as the zoonotic nature of the disease on public health. This work aimed to study the histomorphology of granulomas in samples of lymph nodes and lungs of animals with suggestive lesions of tuberculosis, as well as those similar to the sanitary inspection. The animals clinically healthy ante-mortem, were slaughtered in a slaughterhouse in the northwestern state of Sao Paulo between April 2008 and April 2009, considering that carcasses had lymph nodes with lesions typical of tuberculosis, exhibiting nodular and hemorrhagic appearance. The caseous or calcified lesions, purulent or not, of various sizes and shapes, were also evaluated. Of the 307,661 animals slaughtered in the mentioned period, 494 gross suggestive lesions of tuberculosis and from 29 cities in the state of Sao Paulo, 16 from Mato Grosso do Sul, Goias 15, one from Mato Grosso and Paraná. Among these, 200 samples (40,5%) were processed for histopathological evaluation by hematoxylin-eosin (HE) and 90 (45%) were subjected to Ziehl-Neelsen (ZN) and examined by light microscopy. In HE staining, histopathological changes of tuberculosis were found in 197 (98,5%), classified according to the stage of development adopted by Wango et al.(31), where 29 samples were included in stage I (14,5%), 53 in stage II (26,5%), 87 in stage III (43,5%), 28 in stage IV (14%). In the ZN staining Mycobacterium sp was found in 89 (99%) of the specimens. The rate of tuberculosis in the herd studied was 0,16%. We conclude that the identification of the disease in slaughterhouses and meat companies from significant gross lesions, enables the implementation of effective measures, specifically the origin of the disease in cattle herds, providing control measures to prevent its spread.

Avaliação microbiológica da superfície muscular de carcaças ovinas durante as operações de abate em matadouro

In order to evaluate the hygienic-sanitary conditions of lamb carcasses for human consumption, this study aimed at quantifying populations of indicator microorganisms, such as: mesophiles and psychrotrophs, molds and yeasts, Escherichia coli, Staphylococcus spp. and at identifying pathogenic microorganisms (Salmonella sp. and Listeria spp.). The study was conducted in one lamb slaughterhouse located in the State of São Paulo. Swab samples were collected from muscle surface of forequarter and hindquarter regions of 30 half-carcasses after skinning, evisceration and washing processes. Population counts were between the following values in log10: 2,00 ± 0,32 and 2,59 ± 0,76 UFC/cm2 for mesophiles; 1,52 ± 0,98 and 2,35 ± 1,17 UFC/cm2 for psychrotrophs; 0,75 ± 0,87 and 1,23 ± 0,97 UFC/cm2 for molds and yeasts; 0,00 ± 0,00 and 0,31 ± 0,84 NMP/cm2 for Escherichia coli and 1,75 ± 0,71 and 1,95 ± 0,68 UFC/cm2 for Staphylococcus spp. Salmonella sp. and Listeria spp. were not detected from any of the sampled points. These results indicate the necessity to improve the hygienic-sanitary conditions.
