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.

1. An antimicrobial composition comprising an organic acid and an organic citrus extract, wherein the organic acid is a buffered vinegar at a concentration of approximately 90% to approximately 99.5% w/v, wherein the buffered vinegar is buffered to a pH of 6.1±0.1, and wherein the organic citrus ext
1. An antimicrobial composition comprising an organic acid and an organic citrus extract, wherein the organic acid is a buffered vinegar at a concentration of approximately 90% to approximately 99.5% w/v, wherein the buffered vinegar is buffered to a pH of 6.1±0.1, and wherein the organic citrus extract is derived from an albedo layer of a citrus fruit, a flavedo layer of a citrus fruit, or a combination thereof and is at a concentration of 0.1% to 5% w/v. 2. The antimicrobial composition of claim 1, wherein the organic acid, prior to buffering, has a pH of approximately 5.5 to approximately 7.3. 3. The antimicrobial composition of claim 2, wherein the organic acid, prior to buffering, has a pH of approximately 5.9 to approximately 7.1. 4. The antimicrobial composition of claim 1, wherein the organic acid is at a concentration of between approximately 95% to approximately 99.5% w/v. 5. The antimicrobial composition of claim 1, wherein the buffered vinegar comprises acetic acid and/or a consumable salt equivalent thereof. 6. The antimicrobial composition of claim 1, wherein the buffered vinegar comprises 0.5% to 8% acetic acid. 7. The antimicrobial composition of claim 6, wherein the buffered vinegar comprises 1% to 4% acetic acid. 8. The antimicrobial composition of claim 1, wherein the buffered vinegar is a corn vinegar, a sugar cane vinegar, a glacial acetic vinegar, an apple cider vinegar, or a combination thereof. 9. The antimicrobial composition of claim 1, wherein the organic citrus extract is at a concentration of 0.1% to 1% w/v. 10. The antimicrobial composition of claim 1, further comprising a masker, an emulsifier, or a combination thereof. 11. The antimicrobial composition of claim 10, wherein the masker is at a concentration of 0.05% to 0.2% w/v. 12. A method for reducing microbiological contamination on a food contact surface comprising applying the antimicrobial composition of claim 1 to the food contact surface in an amount effective to reduce or eliminate a microbial population on the food contact surface. 13. The method of claim 12, wherein the organic acid, prior to buffering, has a pH of approximately 5.5 to approximately 6.2. 14. The method of claim 12, wherein the buffered vinegar comprises 0.5% to 8% acetic acid. 15. The method of claim 12, wherein the buffered vinegar is a corn vinegar, a sugar cane vinegar, a glacial acetic acid vinegar, an apple cider vinegar, or a combination thereof. 16. The method of claim 14, wherein the antimicrobial composition is applied as a fine spray or mist. 17. The method of claim 12, wherein the antimicrobial composition is allowed to remain in contact with the food contact surface for at least 30 seconds prior to food coming into contact with the food contact surface. 18. The method of claim 17, wherein the food contact surface is a wood surface, a plastic surface, a rubber surface, a glass surface, or a stainless steel surface. 19. The method of claim 12, wherein the microbial population comprises one or more bacterial species and/or one or more fungal species. 20. The method of claim 19, wherein the bacterial species is a psychrotroph, a coliform, a lactic acid bacterial species, or a spore-forming bacterial species. 21. The method of claim 20, wherein the bacterial species is a Pseudomonas species, a Micrococcus species, an Aerococcus species, a Lactococcus species, Leuconostoc species, a Streptococcus species, a Bacillus species, a Clostridium species, a Eubacterium species, an Enterococcus species, or a Listeria species. 22. The method of claim 21, wherein the bacterial species is a Listeria species. 23. The method of claim 22, wherein the bacterial species is L. monocytogenes. 24. The method of claim 19, wherein the one or more fungal species comprises one or more yeast. 25. The method of claim 24, wherein the yeast is a Geotrichum species, a Saccharomyces species, a Hansenula species, a Candida species, a Kluyveromyces species, a Debaryomyces species, a Pichia species.
