(a) Cleaning. (1) Excreta and food waste must be removed from primary enclosures and from under and around primary enclosures as often as necessary to prevent excessive accumulation of feces and food waste, to prevent soiling of the birds contained in the primary enclosures, and to reduce disease hazards, insects, pests, and odors. When steam or water is used to clean primary enclosures, measures must be taken to protect birds from being harmed, wetted involuntarily, or distressed in the process. Standing water, except for such water in pools or other aquatic areas (e.g., ponds, waterfalls, fountains, and other water features), must be removed from the primary enclosure.

(2) Scheduled cleaning may be modified or delayed during breeding, egg-sitting, or feeding of chicks for birds that are easily disrupted during such behaviors. Scheduled cleaning must resume when such cleaning no longer disrupts breeding, egg-sitting, or feeding of chicks. A schedule of cleaning must be documented and must include when breeding season began, when the primary enclosure was last cleaned, and when cleaning is expected to resume. Such records must be available for review by an APHIS inspector.

(b) Sanitization. (1) Primary enclosures and food and water receptacles for birds must be sanitized as often as necessary to prevent accumulation of dirt, debris, food waste, excreta, and other disease hazards. Provided, however, that sanitization may be modified or delayed during breeding, egg-sitting, or feeding of chicks for those birds that are easily disrupted during such behaviors. Sanitization must resume when such activity no longer disrupts breeding, egg-sitting, or feeding of chicks. A schedule of sanitization must be documented that includes when breeding season began, when the primary enclosure was last sanitized, and when sanitization is expected to resume. Such records must be available for review by an APHIS inspector.

(2) The hard surfaces of primary enclosures and food and water areas and equipment must be sanitized before a new bird is brought into a housing facility or if there is evidence of infectious disease among the birds in the housing facility.

(3) Primary enclosures using materials that cannot be sanitized using conventional methods, such as gravel, sand, grass, earth, planted areas, or absorbent bedding, must be sanitized by removing all contaminated material as necessary or by establishing a natural composting and decomposition system that is sufficient to prevent wasted food accumulation, odors, disease, pests, insects, and vermin infestation.

(c) Housekeeping for premises. Premises where housing facilities are located, including buildings, surrounding grounds, and exhibit areas, must be kept clean and in good repair in order to protect the birds from injury and disease, to facilitate the husbandry practices required in this subpart, and to reduce or eliminate breeding and living areas for rodents, pests, and vermin. Premises must be kept free of accumulations of trash, junk, waste products, and discarded matter. Weeds, grasses, and bushes must be controlled so as to facilitate cleaning of the premises and pest control, and to protect the health and well-being of the birds.

(d) Pest control. A safe and effective program for the control of insects, ectoparasites, and avian and mammalian pests must be established and maintained so as to promote the health and well-being of the birds and reduce contamination by pests in animal areas. Insecticides, chemical agents, or other pest control products that may be harmful to the birds must not be applied to primary enclosures and other bird contact surfaces unless the application is consistent with manufacturer recommendations or otherwise approved for use and does not harm birds.
