摘要

近年来,李斯特菌病在中国的发病率呈上升趋势。李斯特菌病主要通过受污染的食物传播。然而,单核细胞增生李斯特菌的致病性较强,且潜伏期较长,这给确定与食品消费和食品处理习惯相关的风险因素带来了挑战。本研究旨在确定与中国李斯特菌病的食物消费和食物处理习惯相关的风险因素。研究采用匹配病例对照研究(1:1比例)的方法,纳入了2013年1月1日至2022年12月31日期间中国所有符合条件的李斯特菌病病例。研究收集了患者的基本信息以及与食物消费和食物处理习惯相关的可能风险因素。共登记了359例患者,包括208例围产期病例和151例非围产期病例。对围产期组进行了单变量和多变量逻辑分析。在围产期组和非围产期组中,冰淇淋和中式凉菜分别是李斯特菌病的高危食物(几率比(OR)2.09 95%置信区间(CI):1.23-3.55;OR 3.17 95% CI:1.29-7.81);食用剩菜剩饭和饲养宠物分别是高危食物处理习惯(OR 1.92 95% CI:1.03-3.59;OR 3.00 95% CI:1.11-8.11)。在两组人群中,生熟食物分开是一个保护因素(OR 0.27 95% CI:0.14-0.51;OR 0.35 95% CI:0.14-0.89),而冰箱清洁仅在围产期组将感染风险降低了 64.94-70.41%。确定李斯特菌病的高风险食物和食物处理习惯对于改进针对易感人群的食品安全指南非常重要。

Risk factors associated with food consumption and food-handling habits for sporadic listeriosis: a case-control study in China from 2013 to 2022.

The prevalence of listeriosis in China has been increasing in recent years. Listeriosis primarily spreads through contaminated food. However, the resilient causative organism, Listeria monocytogenes, and its extended incubation period pose challenges in identifying risk factors associated with food consumption and food-handling habits. This study aimed to identify the risk factors associated with food consumption and food-handling habits for listeriosis in China. A matched case-control study (1:1 ratio) was conducted, which enrolled all eligible cases of listeriosis between 1 January 2013 and 31 December 2022 in China. Basic information and possible risk factors associated with food consumption and food-handling habits were collected. Overall, 359 patients were enrolled, including 208 perinatal and 151 non-perinatal cases. Univariate and multivariable logistic analyzes were performed for the perinatal group. For the perinatal and non-perinatal groups, ice cream and Chinese cold dishes were the high-risk foods for listeriosis (odds ratio (OR) 2.09 95% confidence interval (CI): 1.23-3.55; OR 3.17 95% CI: 1.29-7.81), respectively; consumption of leftovers and pet ownership were the high-risk food-handling habits (OR 1.92 95% CI: 1.03-3.59; OR 3.00 95% CI: 1.11-8.11), respectively. In both groups, separation of raw and cooked foods was a protective factor (OR 0.27 95% CI: 0.14-0.51; OR 0.35 95% CI: 0.14-0.89), while refrigerator cleaning reduced the infection risk by 64.94-70.41% only in the perinatal group. The identification of high-risk foods and food-handling habits for listeriosis is important for improving food safety guidelines for vulnerable populations.

期刊介绍: Emerging Microbes & Infections is a peer-reviewed, open-access journal dedicated to publishing research at the intersection of emerging immunology and microbiology viruses. The journal's mission is to share information on microbes and infections, particularly those gaining significance in both biological and clinical realms due to increased pathogenic frequency. Emerging Microbes & Infections is committed to bridging the scientific gap between developed and developing countries. This journal addresses topics of critical biological and clinical importance, including but not limited to: - Epidemic surveillance - Clinical manifestations - Diagnosis and management - Cellular and molecular pathogenesis - Innate and acquired immune responses between emerging microbes and their hosts - Drug discovery - Vaccine development research Emerging Microbes & Infections invites submissions of original research articles, review articles, letters, and commentaries, fostering a platform for the dissemination of impactful research in the field.
