ABSTRACT: Bovine cysticercosis and hydatidosis are frequently identified by inspectors in slaughterhouses from the state of Rio Grande do Sul. Slaughterhouse records can provide valuable information for animal-related diseases public health surveillance. Analyzing these data aid set priorities to regions or properties that need more attention. Slaughter condemnation is collected daily stored Agricultural Defense System (SDA) database State Veterinary Services. However, it needs be turned into useful bovine surveillance programs. This study aimed discuss how analysis context epidemiology a system hydatidosis. For this purpose, slaughter 5,137,870 cattle 480,000 animal movement permits (GTA) 97,891 farms 2014 2018 were obtained Secretary Agriculture, Livestock Rural Development Sul (SEAPDR-RS). Differences occurrence rates among mesoregions over time assessed through generalized linear models. Cysticercosis was 65,379 (1.27%) carcasses 323,395 (6.29%). The both varied distinctly between (p<0.01). Next, process developed identify priority target program based on prevalence.
