The aims of this study were to verify the presence of Toxoplasma gondii cysts in fresh pork sausage and the presence of antibodies against T. gondii in serum of workers from factories with Municipal Inspection Service, in Londrina, PR, Brazil. 149 samples of sausage were collected from eight factories and blood samples from 47 workers. We also took information about the practices that were adopted in the factories and the workers' habits that could influence the prevalence of toxoplasmosis. After bioassay in mice, 13 (8.7%) sausage samples were positive, in one of them T. gondii was isolated and in the other 12 the mice seroconverted. Of 47 workers, 36 (76.6%) worked in sausage production and 11 (23.4%) were involved in other functions; 59.5% (28/47), 55.5% (20/36) and 72.7% (8/11), respectively, had T. gondii antibodies. There were no significant differences in the variables of industries' practices and workers' habits related to T. gondii infection. We concluded that fresh pork sausage could be important in the transmission of toxoplasmosis.
本研究的目的是验证巴西巴拉那州隆德里纳市市政检查服务工厂的新鲜猪肉香肠中是否存在刚地弓形虫囊肿,以及这些工厂工人血清中是否存在抗刚地弓形虫抗体。从8家工厂采集了149份香肠样本,从47名工人采集了血液样本。我们还收集了有关工厂采用的做法以及可能影响弓形虫病流行率的工人习惯的信息。在小鼠生物测定后,13份(8.7%)香肠样本呈阳性,其中1份分离出刚地弓形虫,另外12份小鼠血清转化。在47名工人中,36名(76.6%)从事香肠生产,11名(23.4%)从事其他工作;分别有59.5%(28/47)、55.5%(20/36)和72.7%(8/11)的工人有抗刚地弓形虫抗体。在与刚地弓形虫感染相关的行业做法和工人习惯变量方面没有显著差异。我们得出结论,新鲜猪肉香肠可能在弓形虫病传播中起重要作用。
