The objective of this study was to report an outbreak of human toxoplasmosis at a research institution in Londrina, Paraná, from December 2015 to February 2016. Blood samples from 26 symptomatic individuals were collected and the microparticle chemiluminescence immunoassay was performed to detect IgM, IgG and specific IgG avidity test in the official laboratory. A total of 20 people with symptoms and serology compatible with acute toxoplasmosis (IgM positive and IgG with low avidity) were selected as cases, while 45 asymptomatic employees working in the same teams and during the same shifts were selected as controls. All the participants of the investigation answered an epidemiological questionnaire. Three samples of water and one sludge from the institution's supply cisterns, 10 soil samples, 11 plant samples, three cat fecal samples and one domestic feline cadaver were collected for analysis of the polymerase chain reaction (PCR) for T. gondii. After analyzing the epidemiological data, the consumption of vegetables in the restaurant of the institution was the only variable associated with the occurrence of the disease. In laboratory results, all the samples showed negative results to PCR. The rapid recognition of the outbreak, early notification and investigation could have broken the chain of transmission early, thus preventing the emergence of new cases. In addition, the adoption of good food handling practices could have prevented the occurrence of the outbreak.

OBJECTIVE: to demonstrate the experience of implanting toxoplasmosis notification during pregnancy and congenital toxoplasmosis in a Sentinel Unit (SU) and describe reported cases. METHODS: this was a descriptive study of the implantation of a notification protocol using a specific notification form for suspected cases of toxoplasmosis in pregnant women and congenital toxoplasmosis in a reference center in Paraná State, Brazil, from August 2013 to August 2014. RESULTS: all 64 suspected cases were notified and case investigation was completed by the SU Epidemiology Sector; 63 received prenatal care and 51 received treatment during pregnancy; 7 of the children being clinically monitored had confirmed diagnosis of congenital toxoplasmosis. CONCLUSION: implanting toxoplasmosis notification afforded epidemiological, clinical and diagnostic data on the disease that contributed to the assessment of the clinical evolution of children exposed to Toxoplasma gondii.
