Final answer:
Major defects of the equipment used in food (fish) processing include added contaminants, nutrient losses, and food contamination.
Step-by-step explanation:
Major defects of the equipment used in food (fish) processing include added contaminants, nutrient losses, and food contamination. Added contaminants can come from leftover materials, bodily fluids, microorganisms, and fragments, which can lead to equipment failure and consumer ingestion. Nutrient losses can occur during high heat processing or refining grains, resulting in lower vitamin and mineral content. Food contamination can arise from poor hygiene, cross-contamination, and temperature control failure, leading to harmful chemicals and microorganisms in food.
