Which statement about biological contaminants is true?

They are the most dangerous and common cause of foodborne illness They are chemical contaminants They are the least dangerous They only include viruses

Correct Answer:

They are the most dangerous and common cause of foodborne illness

Explanation:

Biological contaminants are living organisms or their byproducts found in food, including bacteria, viruses, parasites, and fungi. They’re the most common source of foodborne illness because they can multiply quickly under improper storage or handling and cause a range of illnesses from mild to severe. While chemical contaminants can cause harm, they are not the primary cause of foodborne illness in typical food safety settings. Viruses are just one type of biological contaminant, not the only one. Therefore, describing biological contaminants as the most dangerous and common cause is accurate. Effective prevention comes from good hygiene, proper cooking temperatures, preventing cross‑contamination, and prompt refrigeration.
