The surveillance systems should be evaluated periodically with objective to become more agile and effective measures to control adverse health events. Thus, the aim of this study was to evaluate the qualitative and quantitative attributes of the Surveillance System for Exogenic Poisoning in Brazil from 2007 to 2009, during which it was linked exclusively to the Occupational Health. For this purpose, there was used the Update Guidelines for Evaluating Public Health Surveillance Systems. A structured questionnaires and database SINAN NET was used as data sources. Of the 27 states of Brazil, 16 answered the questionnaires. The data follow the flow established by Brazilian Surveillance System (SINAN NET), however without setting a statewide coordinating body. As the parameters adopted, the Surveillance System for Exogenic Poisoning was considered simple, flexible, timely and unstable. Data quality and representativeness were regular; and the sensitivity and Positive Predictive Value were low. We recommend establishing a Surveillance System's flow within the state and to develop a Guide for Exogenic Poisoning, defining the goals for this surveillance.
