PHENOLICS
Environ, Tektrol, PineSol, etc:
Not effective against non-enveloped viruses or spores, and concentrations above 2% are highly
toxic to all animals, especially cats. Effective in the presence of organic matter. These products
are not recommended and are no longer permitted to be used as laboratory disinfectants.
IODINES
Due to excessive cost, not widely used in animal care environments. Iodines are in short supply.
BIGUINIDES
Chlorhexidine, Nolvasan, Virosan:
These alter membrane permeability. They only function in a limited pH range of 5–7, and are
toxic to fish and therefore an environmental concern.
Aldehydes
Formaldehyde, Glutaraldehyde:
Denatures proteins, alkylates nucleic acids, broad spectrum, carcinogenic, potent mucous
membrane and tissue irritants, only use in well ventilated areas. Efficacy is reduced with organic
matter. Effective on spores.
OTHER NOTES:
Efficient cleaning can remove 99% of bacteria present. Cleaning is the most crucial step in the
disinfection process.
Foot baths can instill a false sense of security if not used properly!
