Teat dip, liquid detergent and insecticide are stored in this 15-foot-by-21-foot room at Milk Made Dairy in Winton, Calif.

Having a dedicated facility for chemicals improves safety and also makes it easier to keep track of inventory. Delivery trucks can pull right up to the garage door and unload without requiring truck drivers or salesmen to walk through the barns — a biosecurity advantage. The room has access to water, and a drain is located in the middle of the floor, so any chemical spills can be hosed down easily.
