All surfaces should be cleaned thoroughly before disinfection. For basic disinfection, a 1:100 dilution of household bleach (i.e.,
2.5 tablespoons/gallon) or a 1:1,000 dilution of quaternary ammonium compounds (e.g.,
Roccal-D® or
Zephiran®) may be used. This appendix includes instructions for disinfection when a particular organism has been identified. All compounds require a contact time of >10 minutes. Local or state environmental health officers might have recommendations for appropriate disinfectant selection
and precautions for environmental effect. Additional information is available from the Purdue University National Biosecurity
Resource Center for Animal Health Emergencies.*
