The Brookhaven Laboratory Animal Facility (BLAF) provides facilities, and it also establishes requirements for basic level of sanitation, ventilation and shelter. For adequate veterinary care, facility environment and housing requirements, Science at the service of Public health, Food chain safety and Environment.
