(3) Procedures for conditioning an inmate’s participation in the program upon the inmate undergoing drug screening.

(b) The infant and toddler breast milk feeding policy for lactating inmates shall be posted in all locations in the jail where medical care is provided and the provisions of the policy shall be communicated to all staff persons who interact with or oversee pregnant or lactating inmates.

(c) This section applies without regard to whether the jail is operated pursuant to a contract with a private contractor and without regard to whether the inmate has been charged with or convicted of a crime.
