A preliminary survey of Trichinella spp. infection was conducted in Colombian swine herds between 2014 and 2016. A total of 1,773 pigs reared on farms under controlled housing conditions and processed in 34 slaughterhouses were tested either by the artificial digestion of pooled muscle samples (n = 1,173) or by serology (n = 600). In addition, 550 rats trapped on 29 swine farm premises were also tested by artificial digestion. No positive pig samples were detected. Similarly, no Trichinella spp. muscle larvae were detected in rats. These results are in agreement with the lack of historical Trichinella infection reports in domestic and wild animals and humans in Colombia. However, a more extensive epidemiological investigation and a continuous surveillance program are needed to continue declaring swine herds in Colombia free of Trichinella infection.
2014年至2016年期间，对哥伦比亚猪群进行了旋毛虫属感染的初步调查。共有1773头在可控饲养条件下农场饲养并在34家屠宰场加工的猪，通过对混合肌肉样本进行人工消化（n = 1173）或血清学检测（n = 600）进行了检测。此外，在29个猪场捕获的550只大鼠也通过人工消化进行了检测。未检测到阳性猪样本。同样，在大鼠中也未检测到旋毛虫属肌肉幼虫。这些结果与哥伦比亚家畜、野生动物和人类缺乏旋毛虫感染历史报告一致。然而，需要进行更广泛的流行病学调查和持续监测计划，以继续宣布哥伦比亚猪群无旋毛虫感染。
