Preventive vs. reactive• Required by Food Safety Modernization Act
Avoids adverse impacts• Recalls, regulatory action, criminal investigation, food safety complaints, etc.
Prioritizes corrective/preventive action response• Severity and likelihood
Provides for continuous improvementAre you doing this now? How do we prioritize?
Why Risk-Based Approach?
ASQ Risk Based Approach (ISO-9001)

Analyze and prioritize risk• Define acceptable vs. unacceptable
Develop plans to mitigate risk• Prevent and/or correct
Implement plan• Check effectiveness• Establish continuous improvement through
Plan-Do-Check & Act

Seeing symptoms and not systemsCommon Pitfalls
Drain fly activity in the production area Metal wear in a pump Unidentified items in the Hold area
Production left waste in the area at the end of the shift, expecting Sanitation to remove it
Maintenance is supposed to reassemble equipment, but Sanitation did it
Production put the materials in the hold area and expected QA to mark them
Responsibilities are not clearly identified

Thinking of the cause as singularNon-conformance: • A can of household insecticide is found in the maintenance shop
Common Pitfalls
Causes• Standing water on the grounds (broken sprinkler)• Damaged dumpster is leaking product• Air curtains on doors are turned off• Contracted PCO is not addressing it • Lack of “pest sighting” communication with PCO• Lack of awareness of chemical control program
