The effectiveness of a negative air ionization system in the control of aerosols in turkey rearing facilities was explored in two separate studies. Both studies evaluated environmental aerosol samples, ion imbalance measurements, temperature, humidity, barometric pressure, and daily poultry mortality, with the second study including post study bird weights. In the first study a negative air ionization system was installed in one half of a 15 meter by 115 meter curtain walled turkey brooder barn with the other half serving as a control. In the second study a negative air ionization system was installed in one turkey grow out barn. Simultaneous area dust samples were taken on test and control sides several times weekly over a 6 week period for the first study and over 12 weeks for the second study. Use of the negative air ionization system did not result in a notable decrease in aerosol levels in either turkey rearing barn. Bird mortalities were not significantly different between test and control environments in the first study, and in the second study there was actually a significant increase in the death rate in the test barn, suggesting that negative ionization may have been detrimental to turkey health. The authors conclude that use of the negative ionization system is not an effective means of reducing aerosol concentrations in turkey rearing barns.
