  • Publication number: 20180289018
    Abstract: Embodiments disclosed herein provide methods for decontaminating food contact surfaces using a fine spray/mist that comprise an antimicrobial composition comprising an organic acid and an organic citrus extract. The spray application reduces the microbiological populations on the surface of food contact surfaces, including potential pathogens, thereby reducing cross-contamination and improving food safety. The composition described herein can be use to target a number of microbiological pathogens, including L. monocytogenes, which is a known cross-contaminant in retail environments such as deli counters and slicers due to its ability to grow at refrigerated temperatures and moist environments making it a known cause of post-processing contamination of ready-to-eat food products.
