Traditional surveillance systems capture only a fraction of the estimated 48 million yearly cases of foodborne illness in the United States. We assessed whether foodservice reviews on Yelp.com (a business review site) can be used to support foodborne illness surveillance efforts.
We obtained reviews from 2005 to 2012 of 5824 foodservice businesses closest to 29 colleges. After extracting recent reviews describing episodes of foodborne illness, we compared implicated foods to foods in outbreak reports from the U.S. Centers for Disease Control and Prevention (CDC).
Broadly, the distribution of implicated foods across five categories was as follows: aquatic (16% Yelp, 12% CDC), dairy-eggs (23% Yelp, 23% CDC), fruits-nuts (7% Yelp, 7% CDC), meat-poultry (32% Yelp, 33% CDC), and vegetables (22% Yelp, 25% CDC). The distribution of foods across 19 more specific food categories was also similar, with Spearman correlations ranging from 0.60 to 0.85 for 2006-2011. The most implicated food categories in both Yelp and CDC were beef, dairy, grains-beans, poultry and vine-stalk.
Based on observations in this study and the increased usage of social media, we posit that online illness reports could complement traditional surveillance systems by providing near real-time information on foodborne illnesses, implicated foods and locations.
在美国，传统监测系统仅能捕捉到估计每年4800万例食源性疾病病例中的一小部分。我们评估了Yelp.com（一个商业评论网站）上的餐饮服务评论是否可用于支持食源性疾病监测工作。
我们获取了2005年至2012年期间距离29所大学最近的5824家餐饮服务企业的评论。在提取描述食源性疾病发作的近期评论后，我们将涉及的食物与美国疾病控制与预防中心（CDC）疫情报告中的食物进行了比较。
总体而言，涉及的食物在五个类别中的分布如下：水产类（Yelp占16%，CDC占12%）、蛋奶类（Yelp占23%，CDC占23%）、水果坚果类（Yelp占7%，CDC占7%）、肉禽类（Yelp占32%，CDC占33%）以及蔬菜类（Yelp占22%，CDC占25%）。在19个更具体的食物类别中的食物分布也相似，2006 - 2011年的斯皮尔曼相关性在0.60至0.85之间。Yelp和CDC中涉及最多的食物类别都是牛肉、奶制品、谷物豆类、家禽和藤蔓类。
基于本研究中的观察结果以及社交媒体使用的增加，我们认为在线疾病报告可以通过提供关于食源性疾病、涉及的食物和地点的近实时信息来补充传统监测系统。
