If an inspector finds a contagious disease in a colony, he shall direct the beekeeper to destroy the diseased colony and equipment, or to treat the colony according to a schedule approved by the department; providing the inspector shall upon request by the beekeeper obtain a sample of brood that is representative of the apiary as determined by the inspector for submission to an approved state or federal laboratory for verification of the disease. All diseased colonies that are treated by a beekeeper shall be reinspected by an inspector within the period designated by the board. The board may require the beekeeper to pay an amount set by the board not to exceed fifty dollars ($50.00) for each inspection, excluding the initial annual inspection, required to certify that the colonies are apparently free of contagious disease. Colonies that do not respond to treatment within a period specified by the board following the initial inspection shall be destroyed by the beekeeper or an inspector in a manner approved by the department and the contaminated equipment shall be disinfected or burned by the beekeeper or an inspector.
