The department shall establish and maintain one or more multidisciplinary teams in each state region of the division of children and family services. The team shall consist of at least four persons, selected by the department, from professions which provide services to abused and neglected children and/or the parents of such children. The teams shall be available for consultation on all cases where a risk exists of serious harm to the child and where there is dispute over whether out-of-home placement is appropriate.
