(a) The written HACCP plan shall identify the corrective action to be followed in response to a deviation from a critical limit. The HACCP plan shall describe the corrective action to be taken, and assign responsibility for taking corrective action, to ensure:
(1) The cause of the deviation is identified and eliminated;
(2) The CCP will be under control after the corrective action is taken;
(3) Measures to prevent recurrence are established; and
(4) No product that is injurious to health or otherwise adulterated as a result of the deviation enters commerce.
(b) If a deviation not covered by a specified corrective action occurs, or if another unforeseen hazard arises, the establishment shall:
(2) Perform a review to determine the acceptability of the affected product for distribution;
(3) Take action, when necessary, with respect to the affected product to ensure that no product that is injurious to health or otherwise adulterated, as a result of the deviation, enters commerce;
(4) Perform or obtain reassessment by an individual trained in accordance with § 417.7 of this part, to determine whether the newly identified deviation or other unforeseen hazard should be incorporated into the HACCP plan.
