Final answer:
Maria correctly identified the critical control points (CCPs) and established critical limits and corrective actions for her HACCP plan. However, she made a mistake by deciding not to keep records, which is an important part of a HACCP program.
Step-by-step explanation:
There are several things that Maria did correctly when developing her HACCP plan. She identified cooking as the critical control point (CCP) for her grilled items, which is an appropriate choice.
She also determined the critical limits for each CCP, such as cooking hamburgers to 155°F for 15 seconds and chicken to 165°F for 15 seconds. Additionally, Maria established a corrective action for products that were not cooked enough, instructing cooks to keep cooking the meat if it did not feel right or if the color inside was not correct.
However, Maria made a mistake by deciding that record keeping was not necessary for her operation. Record keeping is an essential part of a HACCP program as it allows for tracking and monitoring of critical control points, corrective actions, and any potential hazards. Without proper record keeping, it becomes difficult to ensure the effectiveness of the food safety management system.
