Final answer:

Cross-contamination, physical contamination, and chemical contamination in food, along with prevention methods and strategies in the food industry are crucial aspects of ensuring food safety.


Explanation:

Cross-contamination refers to the contamination of a food by microbes from another food it comes into contact with indirectly or directly. Physical contamination involves the presence of foreign objects like glass, metal, or plastic in food. Chemical contamination occurs when harmful chemicals are present in food, affecting consumer health.


  1. Ways to prevent cross-contamination include using separate cutting boards for raw meat and produce, washing hands before and after handling food, and avoiding using the same utensils for raw and cooked foods.
  2. In the food industry, prevention of physical contamination is achieved through implementing quality control measures, using metal detectors, sieves, and filters, as well as ensuring proper packaging and storage to avoid foreign object contamination.
