[Seroprevalence of brucelosis in the workers of a plant of treatment of sanitary wastes].

Background And Objectives: The management of biosanitary (hospital) waste, while being a key issue in the prevention of public health risks, involves professional risks as well. The objective of this study was to analyze the risks of infection and their relation with the various works within a cluster of brucellosis detected in an infectious waste plant.

Subjects And Method: Cross-descriptive study of the total of 24 employees at the waste plant. A survey was carried out taking into account personal as well as professional items and serological tests. Both bivariant (contingency charts and mean comparison) and multivariant (logistic regression) analyses were carried out.

Results: The seroprevalence of brucella infection was 45.93% (CI95%, 26.17-66.76). The estimated risk (OR) for processing workers was 33.72 (CI95%, 2.73-415.96). The permanence within the posts was not different among groups.

Conclusions: Infection seroprevalence was higher than that found in endemic populations. The post of processing was found to hold a relation with the contact with Brucella sp.
