During the last years, the report of the occurrence of waterborne disease symptoms related to non-enteric pathogens has increased, without any record of higher levels of indicator bacteria ( and intestinal enterococci). Therefore, the use of current indicators is not always adequate when assessing the overall potential health risk and the inclusion of additional parameters needs to be examined. This paper reports on the incidence and levels of at 258 locations in Primorje-Gorski Kotar County (Croatia) recorded by official bathing water quality monitoring, as well as supplemental monitoring carried out at the two most frequented beaches in the City of Rijeka. The number of bathers was found to be the main factor affecting levels (r = 0.321, < 0.05). The share of positive samples from the official monitoring was significantly lower, when compared to the share of samples from supplemental monitoring (2.2% and 36.3%, respectively; < 0.01). Besides the number of bathers, one of the main reasons is likely the higher sampling frequency. No correlation was found between levels and the indicator bacteria. The results indicate that the determination of and increased sampling frequency is recommended for overcrowded beaches.
在过去几年中，与非肠道病原体相关的水传播疾病症状的报告有所增加，但没有任何记录表明指示菌（和肠道肠球菌）的水平更高。因此，在评估整体潜在健康风险时，当前指标的使用并不总是足够的，需要检查其他附加参数的使用。本文报告了在克罗地亚普里莫日-戈尔斯基·科塔尔县（Primorje-Gorski Kotar County）的 258 个地点记录的 的发生率和水平，这些数据是通过官方浴场水质监测获得的，以及在里耶卡市两个最受欢迎的海滩进行的补充监测。发现游泳者人数是影响 水平的主要因素（r = 0.321， < 0.05）。与补充监测相比，官方监测的 阳性样本比例明显较低（分别为 2.2%和 36.3%； < 0.01）。除了游泳者人数外，原因之一可能是更高的采样频率。未发现 水平与指示菌之间存在相关性。结果表明，建议在人满为患的海滩上测定 和增加采样频率。
