The prevalence of Toxoplasma gondii infection in Swedish pigs was investigated by analysis of 807 meat juice samples collected in 1999 from 10 abattoirs in different parts of the country. When analysed using ELISA, 42 (5.2%) of the samples were found to be positive. The seroprevalence was 3.3% in fattening pigs (n = 695) and 17.3% (n = 110) in adult swine. Alternative interpretations of the results, considering estimates of the true prevalence based on the sensitivity and specificity of the test method, are discussed. It is concluded that the risk of contracting T. gondii infection as a result of eating undercooked pork from Swedish pigs, especially adult animals, is not negligible.
通过对1999年从瑞典不同地区10家屠宰场采集的807份肉汁样本进行分析，调查了瑞典猪弓形虫感染的流行情况。采用酶联免疫吸附测定（ELISA）分析时，发现42份（5.2%）样本呈阳性。育肥猪（n = 695）的血清阳性率为3.3%，成年猪（n = 110）的血清阳性率为17.3%。讨论了基于检测方法的敏感性和特异性对真实流行率进行估计时对结果的其他解释。得出的结论是，食用来自瑞典猪尤其是成年猪的未煮熟猪肉而感染弓形虫的风险不可忽视。
