Policy No.2010-1: Recovery of Costs Associated with Satellite Rodent Housing (Rodents Housed in Laboratories or Areas Outside the IAS Facilities)

Approved: April 21, 2010

Reapproved 6/15/2011

Effective Date: October 4, 2010

As of October 4, 2010, laboratories typically housing greater than 10 cages on a regular or sustained basis will be subject to the regular per diem rate for housing rodents in the central facility.

Standard animal welfare policy requires that live animals brought to laboratory or procedural areas outside of the animal facility not be housed in those areas for more than 12 hours.

Certain types of in vivo studies, however, may require keeping live rodents (mice and rats) in laboratory space for longer periods of time (days to weeks). This so called “satellite housing” is possible with the approval of the Institutional Animal Care and Use Committee (IACUC), as long as sufficient scientific justification has been provided.

Animals approved to be held in laboratory satellite facilities are not exempt from animal care and routine husbandry requirements and laboratory investigator staff are responsible for performing and documenting these husbandry tasks. Nevertheless, there are still significant expenses that impact the entire animal care program. Specifically, fresh caging supplies, food, and water are provided by the central animal facility and soiled cages are removed and sanitized by the central facility. Furthermore, the satellite facility must be regularly inspected by the IACUC and the veterinary staff to ensure overall compliance with animal welfare regulations and policies of the institution and external regulatory and funding agencies.

To recover operating expenses the IACUC has instituted the following policy:

  1. Laboratories typically housing greater than 10 cages on a regular or sustained basis will be considered to be large and will be subject to the regular per diem rate for housing rodents in the central facility. Large satellite facilities will be subject to daily rounds by IAS staff, including weekends. Per diem rates will be charged based on the average weekly census in that facility.
  2. Small satellite operations (housing less than 10 cages and only on an intermittent basis) will be subject to periodic audits by the IACUC, but will not be included in regular IAS daily rounds. These laboratories will be exempt from per diem charges for the time being.
