Reason for recall

When the Stealth Chamber is used as a reference detector in relative dosimetry, deviation in the measured PDDs at shallow depths and geometric shadowing of measured profiles may appear.

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.
