A trichinellosis outbreak was investigated (December 1992-January 1993). It occurred in the village of Huerta del Marquesado among people who consumed sausages made with pork, meat. The aim of this study is to show the consequences of consuming meat without a sanitary control on human health.
A case-control study was carried out. Information was obtained using a standardized questionnaire for Foodbornes. A descriptive study was done and the relationship between the intake of sausages and disease was also investigated.
19 cases were reported, median frequency: 11 of January. The outbreak lasted 21 days. The mean incubation period was 26.47 days (SD 4.45 days). Most frequent symptoms were fever, myalgia, eyelid's edema. The age of the patients varied from 5 to 65 years old, being the mean 33 years old. Proportionally more women than men were diseased (58%). No cases died or were hospitalized. A significant statistic association was show between trichinellosis and intake of sausages (OR = 54; 95% Confidence interval 3.1- 2622.43; p < 0.0006). Trichinella spiralis larvae have been shown in samples of the pork meat which had been eaten.
The disease did not last excessively and was not too severe, which suggest a low parasite density. After the laboratory confirmation the meat was confiscated and destroyed. The outbreak was controlled with the active collaboration of the public health veterinarians.
对一次旋毛虫病暴发事件（1992年12月至1993年1月）展开了调查。该事件发生在韦尔塔德尔马克萨多村，涉及食用了用猪肉制作的香肠的人群。本研究旨在揭示食用未经卫生检验的肉类对人类健康造成的后果。
开展了一项病例对照研究。通过一份针对食源性疾病的标准化问卷获取信息。进行了描述性研究，并调查了香肠摄入量与疾病之间的关系。
报告了19例病例，发病中位时间为1月的11日。疫情持续了21天。平均潜伏期为26.47天（标准差4.45天）。最常见的症状为发热、肌痛、眼睑水肿。患者年龄在5至65岁之间，平均年龄为33岁。患病女性比例高于男性（58%）。无病例死亡或住院。旋毛虫病与香肠摄入量之间显示出显著的统计学关联（比值比=54；95%置信区间3.1 - 2622.43；p<0.0006）。在食用的猪肉样本中发现了旋毛虫幼虫。
该疾病持续时间不长且不太严重，这表明寄生虫密度较低。实验室确认后，涉事肉类被没收并销毁。在公共卫生兽医的积极协作下，疫情得到了控制。
