Implementations of the present invention extend to sanitary systems, methods, and devices configured to package food items with an even coating of an accurate amount of sanitizing agent, such as an antimicrobial agent. In one implementation, an exemplary system comprises a combination of air nozzles, anti-bacterial spray nozzles or spray headers, metering valves, and timers to achieve uniform distribution of an antimicrobial solution into a product package, and subsequently provide a uniform distribution of the antimicrobial solution to the food item.
