Step 1: Understanding the Concept:
Hygienic food plant design follows strict zoning principles to prevent the transfer of hazards between processing stages.
Step 2: Detailed Explanation:
Raw agricultural materials naturally harbor high microbial bioburdens, soil contaminants, and unpasteurized pathogens.
Physical segregation and unidirectional flow between raw receiving/preparation zones and ready-to-eat finished product zones prevent cross-contamination via aerosols, equipment, utensils, and personnel.
Step 3: Final Answer:
Thus, separate areas for raw and finished products are required to prevent cross-contamination.
