Nitrito residual em salsichas comercializadas no Brasil procedentes de indústrias fiscalizadas pelo Serviço de Inspeção Federal

Os produtos embutidos são comercialmente importantes para as indústrias processadoras de carnes no Brasil. No processo de fabricação desses produtos, os sais de nitrito são aditivos adicionados intencionalmente a eles, a fim de conferir fixação da cor e sabor, retardar a oxidação lipídica, aumentar a vida útil, e inibir o crescimento de microrganismos. O uso de nitrito em embutidos é estudado principalmente, quanto a possibilidade de causar intoxicações em seres humanos se ingeridos em grandes quantidades. Visto que a salsicha é um produto industrializado embutido com grande aceitação pelo mercado consumidor; foram coletadas aleatoriamente 44 amostras (11 marcas e 04 lotes distintos) de salsichas aptas a serem comercializadas no Brasil, procedentes de indústrias fiscalizadas pelo Serviço de Inspeção Federal (SIF), com o objetivo de verificar o teor de nitrito residual nesses produtos. Os resultados demonstraram que 84,1% das amostras analisadas apresentaram-se conformes à legislação vigente, enquanto que 15,9% estavam não conformes. Amostras não conformes podem indicar um desvio tecnológico na indústria que resultou em falha no processo de produção, e atestam a constante necessidade de medidas de controle e fiscalização por parte dos órgãos governamentais

Brasil.The Triângulo Mineiro region from Minas Gerais state, is an important meat-exporting region of Brazil and data about Toxoplasma gondii infection in pigs raised and slaughtered in this area are scarce. Therefore, the aim of this study was to evaluate the occurrence of T. gondii in swine and establish the risk factors associated with the infection. Samples were collected from 600 pigs raised under intensive system in farms located at three different counties (Carmo do Paranaíba, Patrocínio and Perdizes). The samples were submitted to indirect hemagglutination antibody test with dilution of 1:32 and to indirect immunofluorescence antibody test with a cutoff of 1:64. The occurrence of positive pig was 3.3% (n=20) and 51.8% (n=311) respectively. A significant difference was observed between toxoplasmatic infection and factors such as lineage, animal origin, size of the farm, collective raising with others species, presence of rodents and type of water offered (p≤0.05). There was no difference between gender and the farm goals. The results demonstrated an occurrence of anti-T. gondii antibodies higher than expected for intensive pig raising system on the studied area, which could indicate a possible sanitary management problem on the studied proprieties. Improvements on the raising techniques are necessary to reduce T. gondii infection sources

Occurrence of Toxoplasma gondii and risk factors for infection in pigs raised and slaughtered in the Triângulo Mineiro region, Minas Gerais, Brazil

ABSTRACT: The Triângulo Mineiro region from Minas Gerais state, is an important meat-exporting region of Brazil and data about Toxoplasma gondii infection in pigs raised and slaughtered in this area are scarce. Therefore, the aim of this study was to evaluate the occurrence of T. gondii in swine and establish the risk factors associated with the infection. Samples were collected from 600 pigs raised under intensive system in farms located at three different counties (Carmo do Paranaíba, Patrocínio and Perdizes). The samples were submitted to indirect hemagglutination antibody test with dilution of 1:32 and to indirect immunofluorescence antibody test with a cutoff of 1:64. The occurrence of positive pig was 3.3% (n=20) and 51.8% (n=311) respectively. A significant difference was observed between toxoplasmatic infection and factors such as lineage, animal origin, size of the farm, collective raising with others species, presence of rodents and type of water offered (p≤0.05). There was no difference between gender and the farm goals. The results demonstrated an occurrence of anti-T.gondii antibodies higher than expected for intensive pig raising system on the studied area, which could indicate a possible sanitary management problem on the studied proprieties.
