本研究的目的是验证新鲜猪肉香肠中弓形虫包囊的存在和市检查服务，在隆德里纳，PR，巴西工厂的工人血清中抗弓形虫抗体的存在。从8个工厂采集了149份香肠样品，并从47名工人中采集了血液样品。我们还收集了有关工厂中采用的做法和工人习惯的信息，这些信息可能会影响弓形虫病的流行。经小鼠生物测定，13份（8.7%）香肠样品为阳性，其中1份分离出弓形虫，12份小鼠血清转化。47名工人中，从事香肠生产的36名（76.6%），其他工作的11名（23.4%），弓形虫抗体阳性率分别为59.5%（28/47）、55.5%（20/36）和72.7%（8/11）。不同行业、不同职业人群弓形虫感染的相关变量差异无统计学意义。因此，新鲜猪肉香肠可能是弓形虫病传播的重要媒介。
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.
