To determine if there was parasite contamination in the sand and soil in daycare sandboxes and play areas, with the goal of developing practice guidelines for their management.
One hundred samples of sand and soil from 10 daycare centres in different regions of the province of Quebec, collected between April 22 and May 6, 1991, were examined.
Toxocara eggs were found in both surface and subsurface sand from two Montreal centres and co-occurred with Ascaris species (surface sand) in one centre and with hookworm (surface soil) in the second. Hookworm eggs were also recovered from one centre in the Quebec City region.
These results document the presence of potentially pathogenic helminth parasites in the daycare environment. Evidence from the literature regarding the health risk to children is insufficient and highlights the need for further research into the assessment of the risk of human infection and morbidity, the viability of these parasites under different environmental conditions and practical issues related to the management of sand and soil.
确定日托中心沙箱和游乐区域的沙子及土壤中是否存在寄生虫污染，以期制定相关管理实践指南。
对1991年4月22日至5月6日期间从魁北克省不同地区10所日托中心采集的100份沙子和土壤样本进行检测。
在蒙特利尔的两个中心，表层和次表层沙子中均发现了弓蛔虫卵，在其中一个中心还与蛔虫属（表层沙子）共同出现，在另一个中心则与钩虫（表层土壤）共同出现。在魁北克市地区的一个中心也发现了钩虫卵。
这些结果证明日托环境中存在潜在致病性的蠕虫寄生虫。文献中关于儿童健康风险的证据不足，这凸显了有必要进一步研究人类感染风险和发病率的评估、这些寄生虫在不同环境条件下的生存能力以及与沙子和土壤管理相关的实际问题。
