A retrospective study of Cysticercus bovis in cattle raised and slaughtered in the State of S. Paulo, Brazil, during the year of 1986, was undertaken on the basis of official records of the Brazilian Meat Inspection Service.

The prevalence rates of each political-administrative unit were statistically compared using the "Z" test of two proportions. From records relating to 896,654 head, 48,957 cases of cysticercosis were detected, equivalent to a prevalence of 5.5% in the State.
