The regulations may provide for an inspection schedule at each slaughterhouse and include provision for inspection in addition to the basic inspection schedule. Additional inspection services shall be provided on a reimbursement basis at the expense of the slaughterer requesting the additional service and shall not be an added charge to the consignor or seller of the livestock. The fees for the additional service shall be established by regulation.
