Interpretive Summary:

Technical Abstract: Microbial contamination is an undesirable condition that occurs due to the presence of microbes, including bacteria, viruses, fungi, and parasites. However, for the purpose of this chapter, contamination refers to harmful or unwanted microbes, as some microbes are beneficial, and their presence is necessary in certain foods. Microbial food contamination can occur at any stage of the food chain, including pre- and post-harvesting, processing, packing, transportation, and distribution. In the food industry, precisely the food processing environment, microbial contamination mostly occurs due to the unintentional introduction of microorganisms such as bacteria, viruses, or other microbes. These microorganisms pose a threat to the food industry due to adverse effects on foods and the public. The most common microbial contamination in the food processing environment is the formation of biofilms. Biofilm formation is challenging for the food industry because moisture, a critical factor for biofilm formation, is unavoidable in the food processing environment. Identification of the sources of contamination is the first step in controlling and preventing microbial contamination. Good Manufacturing Practices (GMP) and the HACCP approach have been common ways to prevent microbial contaminants in food processing. However, contamination with microorganisms continues to be an issue. For this purpose, adequate risk assessment and detection methods are essential. The food industry should not rely on traditional approaches for detecting, controlling, and preventing microbial contamination, but they should seek innovative and emerging technologies. The present chapter focuses on identifying the source of microbial contamination in food processing, detection methods, and emerging and innovative technologies for controlling microbial contamination in food processes.
