(a) Investigation Specialists, Intact Family Specialists, and Placement Specialists employed by the Department of Children and Family Services who reasonably believe that an animal observed by them when in their professional or official capacity is being abused or neglected in violation of the Humane Care for Animals Act must immediately make a written or oral report to the Department of Agriculture’s Bureau of Animal Health and Welfare. However, the Department of Children and Family Services may not discipline an Investigation Specialist, an Intact Family Specialist, or a Placement Specialist for failing to make such a report if the Specialist determines that making the report would interfere with the performance of the specialist’s child welfare protection duties.
     (b) A home rule unit may not regulate the reporting of child abuse or neglect in a manner inconsistent with the provisions of this Section. This Section is a limitation under subsection (i) of Section 6 of Article VII of the Illinois Constitution on the concurrent exercise by home rule units of powers and functions exercised by the State.
