Michigan Compiled Laws, Chapter 287. Animal Industry § 287.530

Sec. 10. A manufacturer that voluntarily recalls a commercial feed that has been introduced into channels of trade beyond its control, and that supports the conclusion that the feed processed by the manufacturer is adulterated or misbranded in a manner that creates an unreasonable risk to animals or to the public health, shall immediately notify the director of the recall and the reasons for the recall. The notification may be oral if it is followed by a written notice to the director. Information or a statement exclusively derived from notification required under this section, except for information contained in records required to be maintained under this act, shall not be used as evidence in a proceeding brought against the person pursuant to this act with respect to a violation of law occurring prior to or concurrently with the notification. The notification required by this section shall contain a clear description of the adulterated or misbranded feed, an evaluation of the risk related to the feed, and a statement of the measures to be taken to protect animals or the public from the risk.
