Which of the following issues is NOT a concern of traditional food safety systems?

The statement that traditional food safety systems "always guarantee food safety" is correct because no food safety system can guarantee that food is completely safe at all times. Traditional food safety systems often rely on end-product testing or reactive measures, which means they check for contaminants after they are present rather than preventing them from occurring in the first place. This inherent limitation prevents any assurance of absolute safety.

In practice, while traditional methods are essential, they are not foolproof and do not provide a comprehensive solution to food safety risks, making it impossible to claim a 100% guarantee of safety. Acknowledging this limitation is crucial for food safety professionals, as it emphasizes the importance of integrating preventive measures, like those found in HACCP (Hazard Analysis and Critical Control Points) systems, which focus on identifying and controlling potential hazards before they can lead to food safety issues.
