Question 1 of 30

\"AgriTest Labs,\" an ISO/IEC 17025:2017 accredited testing laboratory, specializes in microbiological testing of food products. Recently, the lab has been experiencing inconsistent results in detecting *Salmonella* in ready-to-eat salads. Internal investigations reveal that despite having a documented cleaning and sanitation program, the effectiveness of these procedures varies significantly between shifts, leading to occasional cross-contamination issues. The lab manager, Isabella Rodriguez, is tasked with addressing this issue within the framework of ISO 22000:2018 principles integrated into their food safety management system. Considering the lab\'s accreditation and the requirements of ISO 22000:2018, which of the following actions should Isabella prioritize to ensure the reliability of their testing services and maintain compliance with food safety standards, focusing specifically on addressing the identified root cause of the problem rather than solely treating the symptoms? The laboratory\'s primary goal is to ensure accurate and consistent *Salmonella* detection to safeguard public health and maintain its accreditation status.

Conduct a thorough review and enhancement of the cleaning and sanitation prerequisite program (PRP), including verification of effectiveness, training enhancements, and implementation of monitoring activities to ensure consistent hazard control.

Implement a more rigorous sample preparation technique specifically for *Salmonella* detection in salads, regardless of the existing cleaning protocols, to minimize the impact of potential cross-contamination.

Increase the frequency of *Salmonella* testing in ready-to-eat salads to compensate for the inconsistent results, without making changes to the current cleaning and sanitation procedures.

Re-evaluate the laboratory's overall quality management system, focusing on documentation control and record-keeping practices, while maintaining the current cleaning and sanitation protocols.
