Final answer:
At least two things that must be cleaned in the pizza assembly line are the food contact surfaces (counters, prep areas) and the cooking equipment (ovens, pizza stones, tools). Additionally, maintaining the air conditioning system and regularly reviewing cleanliness practices are important for food safety.
Step-by-step explanation:
When cleaning the pizza assembly line, there are several aspects that must be addressed to ensure proper hygiene and food safety. First, the surfaces that come into direct contact with food, such as the countertops and prep areas, must be thoroughly cleaned.
This prevents cross-contamination and the growth of bacteria. Second, the cooking equipment, including pizza ovens, pizza stones, and any tools used like pizza cutters or dough presses, need regular cleaning to remove food residue and potential allergens.
Beyond these, other important items to clean include storage areas, refrigeration units, and utensils.
Specific to the case mentioned, where a store ordered a comprehensive cleaning of the air conditioning system, it is important to include regular maintenance of such systems to prevent issues like the growth of biofilms.
This, along with reviewing practices at other facilities, ensures a broader approach to cleanliness and food safety in the food service environment.
