, a member of the genus , is widely distributed in agricultural environments, such as soil, manure and water. This organism is a recognized foodborne pathogenic bacterium that causes many diseases, from mild gastroenteritis to severe blood and/or central nervous system infections, as well as abortion in pregnant women. Generally, processed ready-to-eat and cold-stored meat and dairy products are considered high-risk foods for infections that cause human illness (listeriosis). However, recently, several listeriosis outbreaks have been linked to fresh produce contamination around the world. Additionally, many studies have detected in fresh produce samples and even in some minimally processed vegetables. Thus may contaminate fresh produce if present in the growing environment (soil and water). Prevention of biofilm formation is an important control measure to reduce the prevalence and survival of in growing environments and on fresh produce. This article specifically focuses on fresh produce-associated listeriosis outbreaks, prevalence in growing environments, contamination levels of fresh produce, and associated fresh produce safety challenges.
属的成员广泛分布于农业环境中，如土壤、粪便和水中。这种微生物是一种公认的食源性病原体，可引发多种疾病，从轻度肠胃炎到严重的血液和/或中枢神经系统感染，以及孕妇流产。一般来说，加工过的即食冷藏肉类和乳制品被认为是导致人类患病（李斯特菌病）的李斯特菌感染的高风险食品。然而，最近，世界各地的几起李斯特菌病疫情都与新鲜农产品污染有关。此外，许多研究在新鲜农产品样本甚至一些最低限度加工的蔬菜中检测到了李斯特菌。因此，如果生长环境（土壤和水）中存在李斯特菌，它可能会污染新鲜农产品。预防生物膜形成是减少生长环境和新鲜农产品中李斯特菌的流行率和存活率的重要控制措施。本文特别关注与新鲜农产品相关的李斯特菌病疫情、生长环境中的流行率、新鲜农产品的污染水平以及相关的新鲜农产品安全挑战。
