Cleaning chemicals, sanitizers, and machine lubricants are examples of which contaminant category?

• A. Biological Contaminants
• B. Allergen Contaminants
• C. Chemical Contaminants
• D. Physical Contaminants

Answer: (C)

Chemical contaminants are substances that contaminate food due to chemicals used in the kitchen, not living organisms or physical objects. Cleaning chemicals, sanitizers, and machine lubricants fall into this category because they are chemical substances that can leave residues on surfaces, equipment, or food if not used, rinsed, or stored properly. Residues can cause illness, taste or odor issues, or chemical burns, so food-contact surfaces must be cleaned and then rinsed or dried according to product guidelines, and chemicals should be stored away from food.

They’re not biological contaminants (which are living organisms like bacteria or viruses), not physical contaminants (like glass or metal shards), and not allergens (which are proteins that trigger immune reactions). The key point is that these items are chemical substances that can contaminate food if mishandled.
