Abstract：
Pseudomonas aeruginosa is a common pathogen associated with recreational water facilities and poses risks to public health. However, data on the prevalence of P. aeruginosa in tourist destinations like the Canary Islands, Spain, remain limited. We assessed P. aeruginosa prevalence in 23 tourist facilities from 2016 to 2019. Compliance with water quality standards was evaluated, and 3962 samples were collected and analyzed. We examined different types of recreational water installations, including outer swimming pools, whirlpools, and cold wells. Of the sampled facilities, 31.2% did not comply with the current legislation\'s parametric values, mainly due to inadequate disinfectant levels, water temperature, and P. aeruginosa presence. The prevalence of P. aeruginosa was 4.8%, comparable to some European countries but lower than others. Cold wells displayed the highest non-compliance rate (89.2%) and yet exhibited a lower P. aeruginosa prevalence (1.9%) than outer swimming pools and whirlpools. Children\'s presence did not significantly impact P. aeruginosa contamination. Chlorine-based disinfectants are more effective than bromine-based ones in controlling P. aeruginosa. Regional variability in contamination was observed, with Fuerteventura showing lower colonization rates. Disinfectant levels play a critical role in P. aeruginosa control, and maintaining adequate levels is essential, particularly in bromine-treated installations. Our findings provide valuable insights into the prevalence and distribution of P. aeruginosa in recreational waters within tourist facilities. Tailored strategies are needed to ensure water safety in different Spanish regions. Continued monitoring and assessment, combined with artificial intelligence and machine learning, will enable the implementation of targeted interventions to protect the health of recreational water users.
摘要：
铜绿假单胞菌是与娱乐用水设施相关的常见病原体，对公众健康构成风险。然而,关于像加那利群岛这样的旅游目的地铜绿假单胞菌患病率的数据，西班牙,保持有限。我们评估了2016年至2019年23个旅游设施中铜绿假单胞菌的患病率。对符合水质标准的情况进行了评估，收集和分析了3962个样本。我们检查了不同类型的休闲水装置，包括室外游泳池,漩涡,冷井。在采样的设施中，31.2%的人不符合现行立法的参数值，主要是由于消毒剂水平不足，水温,和铜绿假单胞菌的存在。铜绿假单胞菌的患病率为4.8%,与一些欧洲国家相当，但低于其他国家。冷井显示出最高的不符合率（89.2％），但铜绿假单胞菌的患病率（1.9％）却低于外部游泳池和漩涡。儿童的存在对铜绿假单胞菌污染没有显著影响。在控制铜绿假单胞菌方面，基于氯的消毒剂比基于溴的消毒剂更有效。观察到污染的区域差异，Fuerteventura的定殖率较低。消毒剂水平在铜绿假单胞菌控制中起关键作用，保持足够的水平至关重要，特别是在溴处理的装置。我们的发现为旅游设施内休闲水域中铜绿假单胞菌的流行和分布提供了宝贵的见解。需要量身定制的策略来确保西班牙不同地区的水安全。继续监测和评估，结合人工智能和机器学习，将能够实施有针对性的干预措施，以保护娱乐用水者的健康。
