犬弓蛔虫和猫弓蛔虫是狗、猫和狐狸的肠道寄生虫，受感染的动物会在粪便中排出寄生虫卵。如果人类不小心摄入了弓蛔虫胚胎。如果虫卵脱离环境，可能会发生严重的临床后果，包括失明和脑损伤。之前的工作已经证明了弓蛔虫属的存在。在英国种植的蔬菜上产卵，但仅限于小型社区花园。本研究的目的是确定弓蛔虫属是否属于弓蛔虫属。英国商业农场种植的蔬菜中也含有鸡蛋，这些农场为更多的人提供农产品。从英国英格兰南部的四个农场收集了总共 120 个菠菜 (Spinacia oleracea) 样品（每个 300 克）。使用筛分方法处理样品，然后进行多重定量聚合酶链反应分析。总体而言，23.0% 的样本对犬毛虫呈阳性（28/120；95% 置信区间 16.7–31.7%），1.7% 的样本对猫毛虫呈阳性（2/120；95% 置信区间 0.5–5.9%）。各养殖场阳性样本数差异有统计学意义（P = 0.0064）。据我们所知，这是首次分离弓蛔虫属的报告。来自英国商业农场种植的蔬菜。这项研究的结果强调了在食用蔬菜之前彻底清洗蔬菜的要求，特别是那些无需先去皮或烹饪即可食用的菠菜，以及有效的农场生物安全措施，以尽量减少弓蛔虫属最终宿主物种进入农田。
Toxocara canis and Toxocara cati are intestinal parasites of dogs, cats and foxes, with infected animals shedding eggs of the parasite in their faeces. If humans accidentally ingest embryonated Toxocara spp. eggs from the environment, severe clinical consequences, including blindness and brain damage, can occur. Previous work has demonstrated the presence of Toxocara spp. eggs on vegetable produce grown in the UK, but only in small-scale community gardens. The aim of this study was to determine whether Toxocara spp. eggs are also present on vegetables grown on commercial farms in the UK, which supply produce to a greater number of people. A total of 120 samples (300 g each) of spinach (Spinacia oleracea) were collected across four farms in the south of England, UK. The samples were processed using a sieving approach followed by multiplex quantitative polymerase chain reaction analysis. Overall, 23.0% of samples were positive for T. canis (28/120; 95% confidence interval 16.7–31.7%) and 1.7% for T. cati (2/120; 95% confidence interval 0.5–5.9%). There was a statistically significant difference in the number of positive samples between farms (P = 0.0064). To our knowledge, this is the first report of the isolation of Toxocara spp. from vegetables grown on commercial farms in the UK. The results of this study highlight the requirement for the thorough washing of vegetables prior to their consumption, especially those such as spinach which may be eaten without first peeling or cooking, and effective farm biosecurity measures to minimise access to farmland by definitive host species of Toxocara spp.
