Contact with raw meat could represent a risk for Toxocara infection. We assessed the association of Toxocara infection with an occupation of meat worker though a case-control seroprevalence study of 124 meat workers and 248 subjects without this occupation. Sera of participants was analyzed for the presence of anti-Toxocara IgG antibodies. One (0.8%) of the 124 meat workers, and 5 (2.0%) of the 248 controls were positive for anti-Toxocara IgG antibodies (OR=0.39; 95% CI: 0.04-3.41; P=0.66). The seropositive meat worker was a male aged 28 years old, without vision impairment. None of the work characteristics i.e. frequency of contact with raw meat, use of safety practices, history of splashes at face with blood or raw meat, and injuries with sharp material at work was associated with Toxocara exposure. Seroprevalence of Toxocara infection was significantly higher (P=0.04) in meat workers with consumption of boar meat (1/6: 16.7%) than in those without this consumption (0/117: 0%). We conclude that meat workers do not have a higher risk for Toxocara infection than subjects without this occupation do. The 2% seroprevalence of Toxocara infection found in control subjects might suggest a low seroprevalence of this infection among people with other occupations in Durango City. However, additional case-control studies with larger sample sizes to confirm our results are needed.
接触生肉可能会带来弓蛔虫感染的风险。我们通过一项病例对照血清流行率研究，对124名肉类加工工人和248名非肉类加工工人进行了评估，以确定弓蛔虫感染与肉类加工工人职业之间的关联。分析了参与者血清中抗弓蛔虫IgG抗体的存在情况。124名肉类加工工人中有1名（0.8%）抗弓蛔虫IgG抗体呈阳性，248名对照中有5名（2.0%）呈阳性（比值比=0.39；95%置信区间：0.04-3.41；P=0.66）。血清学阳性的肉类加工工人是一名28岁男性，无视力障碍。工作特征，即接触生肉的频率、安全措施的使用、面部被血液或生肉溅到的历史以及工作中被尖锐材料划伤的情况，均与弓蛔虫暴露无关。食用野猪肉的肉类加工工人中弓蛔虫感染的血清流行率（1/6：16.7%）显著高于未食用野猪肉的工人（0/117：0%）（P=0.04）。我们得出结论，肉类加工工人感染弓蛔虫的风险并不高于非肉类加工工人。在对照对象中发现的2%的弓蛔虫感染血清流行率可能表明杜兰戈市其他职业人群中这种感染的血清流行率较低。然而，需要进行更多样本量更大的病例对照研究来证实我们的结果。
