Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii, a protozoan whose definitive hosts are cats, among them domestic cat, which can transmit the infection to humans. In Chile, there are no published studies on seroprevalence in people with occupational risk. Thus, this study aimed to determine the seroprevalence of Toxoplasma gondii and associated risk factors in operators of a slaughter plant in Bío-Bío (Chile). Serum samples from 39 operators were collected and studied by chemiluminescence analysis in order to detect IgG and IgM antibodies, with a sensitivity and specificity of 93 and 96%, respectively. An epidemiological survey was conducted and odds ratio was calculated for the analysis of the variables of hygiene, food, and exposure. Evidence showed that 24 individuals had IgG antibodies for an apparent seroprevalence of 61.5%, while this was 0% for IgM. In addition, the highest seropositivity was observed in operators who did not use masks (64%) and did not disinfect the working material (100%), as well as in those who consumed undercooked meat (62.5%). Regarding exposure time, 72.7% was obtained for the group of more than 10 years, and 62.2% of seropositivity was found in those exposed between four and seven days a week. There were no significant differences for any of the analyzed variables (p > 0.05). The study concludes that there is a high seroprevalence of Toxoplasma gondii in workers with occupational risk at the Bío-Bío slaughter plant. |
