14. A food processing facility having an interior space, comprising:
(a) application apparatus located within the interior space for applying a PAA solution to food;
(b) a PAA gas sensor, located within the interior space for sensing a PAA airborne concentration;
(c) a fresh air ventilation system for introducing outside air to the interior space of the food processing facility;
(d) an actuation control system connected to the PAA gas sensor adapted to receive from the PAA gas sensor a measure of the PAA airborne concentration sensed by the PAA gas sensor and to increase the flow rate of the fresh air ventilation system when the measure of the PAA airborne concentration exceeds a reference value; and
(e) a mixing container for containing the PAA solution having a PAA solution concentration, the mixing container connected to the application apparatus within the interior space for delivering the PAA solution to the application apparatus, a water line connected to the mixing container for delivering feed water to the mixing container, and a PAA line connected to the mixing container for delivering PAA to the mixing container, wherein the actuation control system is adapted to actuate a control valve in one of the water line and the PAA line to reduce the PAA solution concentration of the PAA solution in the mixing container when the measure of the PAA airborne concentration exceeds the reference value.
