Reason for recall

Due to a system controller software anomaly, the patient positioning deviation correction may not be applied and may result in the wrong part of the patient being irradiated.

The USDA issues these when meat or poultry was produced without proper inspection, or when a step such as cooking or pasteurisation did not meet requirements.
