title: [The prevalence of anti-Toxoplasma gondii antibodies among abattoir workers in Lublin].
abstract: Abattoir workers are occupationally exposed to Toxoplasma gondii by the contact with raw meat. One hundred and seven abattoir workers from the Meat Factory in Lublin were examined for the presence of anti-Toxoplasma antibodies. Sixty-one blood donors were also tested as the reference group. Sera from workers and referents were tested by direct agglutination with 2-mercaptoethanol (DA-2ME), and also by ELFA IgG and ELFA IgM tests (Vidas Toxo IgM, Vidas Toxo IgG, bioMerieux, France). In the workers group, out of 107 tested sera, 70 were found positive (65.4%). The highest percentage of seropositive results was found in the Cured Meat Division--76.2%. In the Meat Production Division 66.6% of seropositive results were found, and in the Slaughter Division--46.1%. Three persons with the presence of IgM antibodies were found in the Cured Meat Division. In the reference group, 34 out of 61 sera (55.7%) were positive. The difference in seropositivity between Cured Meat Division workers and reference group was statistically significant (p < 0.05). The high percentage of seropositive reactions among the workers of Cured Meat Division and the presence of persons in early stage of invasion suggest an increased risk of exposure to T. gondii in this section.
