List three potential contamination sources in a processing facility and a control measure for each.

Explanation:
Contamination prevention in a processing facility focuses on controlling the main ways hazards can enter the product: water that comes into contact with the product or cleaning processes, the air that surroundings and processes release into the workspace, and the surfaces and equipment that touch the product itself. Treating and verifying the water supply helps prevent microbial or chemical contaminants from being introduced through water uses. Implementing clean, HEPA-filtered air handling and a well-maintained HVAC system reduces airborne particles and microorganisms that could settle on products or surfaces, cutting environmental contamination and cross-contact risk. Keeping raw product contact surfaces separate with dedicated equipment, plus color-coding and rigorous sanitation, prevents cross-contact between different products and residues from one batch affecting another. These controls address contamination at its sources rather than waiting for detection later in the process. Other options fall short: relying on metal detectors targets metal after processing rather than preventing it from entering; suggesting no controls for raw products ignores the risk of cross-contamination; and using lighting to detect contaminants does not provide a preventive or reliable control for microbial or chemical hazards.
