Federal probe into deadly listeria outbreak finds major flaws with algorithm guiding inspections

A federal investigation into a deadly listeria outbreak last year has found significant flaws with an algorithm-based system deployed by the Canadian Food Inspection Agency that oversees how often food-production facilities are inspected.

A report by CFIA Inspector-General Scott Rattray also found the agency has failed to meet its annual inspection targets – and that a large number of facilities have not been scrutinized because of weaknesses in the system.
