Humidity and lumens of light are checked quarterly and recorded. Any deviation from the normal is reported to the UAC facility maintenance employee, and the Facilities Management unit is called in to adjust the temperature, humidity, or lights. Light timers are also checked daily to assure proper function. Room logs are also used to record any other environmental problem, such as insects, broken equipment etc. Problems are reported to one of the supervisors or to the UAC maintenance person for correction.
All feed is checked upon arrival to assure that no outdated feed is received.
The oldest milling date is always used first, and in no instance can feed with a milling date greater than 90 days be used. Feed infested with vermin is immediately disposed of and all containers cleaned and washed. Plastic cards are attached to the food barrels in the animal rooms. The card will state the milling date, date the food was placed in the barrel and type of food in the barrel. A sample of each type of feed is tested twice a year for pathogenic bacteria.
