Southern California is an increasingly urbanized hotspot for surfing, thus it is of great interest to assess the human illness risks associated with this popular ocean recreational water sport from exposure to fecal bacteria contaminated coastal waters. Quantitative microbial risk assessments were applied to eight popular Southern California beaches using readily available enterococcus and fecal coliform data and dose-response models to compare health risks associated with surfing during dry weather and storm conditions. The results showed that the level of gastrointestinal illness risks from surfing post-storm events was elevated, with the probability of exceeding the US EPA health risk guideline up to 28% of the time. The surfing risk was also elevated in comparison with swimming at the same beach due to ingestion of greater volume of water. The study suggests that refinement of dose-response model, improving monitoring practice and better surfer behavior surveillance will improve the risk estimation.
南加州是一个日益城市化的冲浪热点地区，因此评估人们在接触受粪便细菌污染的沿海水域时因这项流行的海洋娱乐性水上运动而患病的风险具有重要意义。利用易获得的肠球菌和粪大肠菌群数据和剂量反应模型，对南加州 8 个受欢迎的海滩进行了定量微生物风险评估，以比较在干燥天气和风暴条件下冲浪相关的健康风险。结果表明，风暴后冲浪的肠胃疾病风险增加，超过美国环保署健康风险指南的概率高达 28%。由于摄入的水量更大，与在同一海滩游泳相比，冲浪的风险也更高。该研究表明，改进剂量反应模型、改善监测实践和更好地监测冲浪者行为将提高风险评估的准确性。
