Appropriate action is taken to identify and correct a problem that has occurred with implementation of a preventive control;

Appropriate action is taken when necessary, to reduce the likelihood that the problem will recur;

All affected animal food is evaluated for safety; and

Take corrective action to identify and correct the problem;

Reduce the likelihood that the problem will recur;
