Introduction
Biofilms are communities of microorganisms surrounded by extracellular polymeric substances (EPS) that can grow on all types of hydrated surfaces, including foodstuffs, food processing equipment, and medical devices. In the food industry, biofilm formation can lead to food contamination, reduced shelf life of food products, and transmission of disease; accordingly, a variety of antimicrobial agents are commonly employed to control biofilm formation. While usually effective, microorganisms periodically develop resistance to antimicrobial agents, something that has become an ongoing challenge to the food industry. Countermeasures to antimicrobial ...
