Microorganisms can colonize and subsequently form biofilms on surfaces, which protect them from adverse conditions and make them more resistant than their planktonic free-living counterparts. This is a major concern in the food industry because the presence of biofilms has significant implications for microbial food contamination and, therefore, for the transmission of foodborne diseases. Adequate hygienic conditions and various preventive and control strategies have consequently been developed to ensure the provision of safe, good-quality food with an acceptable shelf-life. This review focuses on the significance of biofilms in the food industry by describing the factors that favor their formation. The interconnected process among bacteria known as "quorum sensing," which plays a significant role in biofilm development, is also described. Furthermore, we discuss recent strategic methods to detect, quantify, and remove biofilms formed by pathogenic bacteria associated with food processing environments, focusing on the complexity of these microbial communities.
微生物可以在表面定殖并随后形成生物膜，生物膜可保护它们免受不利条件的影响，使其比浮游自由生活的同类微生物更具抗性。这在食品工业中是一个主要问题，因为生物膜的存在对微生物食品污染有重大影响，因此对食源性疾病的传播也有重大影响。因此，已经制定了适当的卫生条件以及各种预防和控制策略，以确保提供具有可接受保质期的安全、优质食品。本综述通过描述有利于生物膜形成的因素，重点阐述了生物膜在食品工业中的重要性。还描述了细菌之间被称为“群体感应”的相互关联过程，该过程在生物膜形成中起着重要作用。此外，我们讨论了检测、量化和去除与食品加工环境相关的致病细菌形成的生物膜的最新战略方法，重点关注这些微生物群落的复杂性。
