Animal rooms, corridors, storage spaces, and other areas should be cleaned with appropriate detergents or disinfectants as often as necessary. Cleaning utensils, mops, pails, and brooms should not be transported between animal rooms. If animal waste is removed by hosing or flushing, this should be done at least once daily. Litter from cages should be emptied in an area other than the animal room. Where pheromones are essential to reproduction, cage cleaning may be less frequent.
Cages are to be washed and sanitized at least every two weeks.
Disinfection is achieved at 180o F. Autoclaving of sipper tubes is recommended. Deodorizers are not appropriate to most animal odors. Such products are not a substitute for good sanitation and can also cause change in microsomal enzymes.
