ALCOHOLS (Isopropyl or Ethyl Alcohol)

• Wide germicidal activity, non corrosive, but poses a fire hazard.
• Limited residual activity due to evaporation.
• Alcohols provide limited activity in the presence of organic matter.
• Not considered effective against bacterial or fungal spores.
• Excellent for disinfecting instruments or other small objects.
• Too expensive for general use in the hatchery.
• Must use as a 70-95% concentration for effectiveness.

QUATERNARY AMMONIUM COMPOUNDS

• Limited germicidal range.
• Not sporocidal, effective against vegetative bacteria, fungi and viruses.
• Reduced efficiency in the presence of organic matter.
• Limited effectiveness in soaps, detergents and hard water salts.
• Non-irritating, non-corrosive and low toxicity.
• Residual activity is limited by the amount of recontamination.
• Good disinfectant for use on cleaned surfaces.
• Low cost.

PHENOLICS (Single or Multiple)

• Wide germicidal range, not sporocidal.
• Low toxicity and low corrosiveness.
• Very effective in the presence of organic matter.
• Good residual activity and deodorizer.
• Low to moderate cost.

COAL TAR DISTILLATES ( Cresol and Cresylic Acid)

• Wide germicidal activity, not sporocidal.
• Corrosive and toxic at high concentrations.
• Excellent residual activity with heavy odor.
• Highly efficient in presence of organic matter.
• Not well suited for use near eggs or chicks due to noxious gases.
• Moderately expensive.

ALDEHYDES (Glutaraldehyde)

• Wide germicidal activity, sporocidal and fungicidal.
• Slight to moderate efficiency in presence of organic matter.
• Slight residual activity.
• Moderately toxic.
• Moderate cost.

OXIDIZING AGENTS (Hydrogen peroxide, Potassium Permanganate)

• Moderate to wide germicidal activity, not sporocidal.
• Rendered ineffective in the presence of organic matter.
• Moderately corrosive, limited toxicity.
• Poor to limited residual activity.
• More valuable as a cleansing and deodorizing agent.
• Moderate cost.
