Step 1: Understanding processing contaminants.
- Nitrosamines are contaminants formed during food processing, especially in cured meats, due to reactions with nitrates at high temperatures.
Step 2: Explanation of incorrect options.
- Mycotoxins (A) and Aflatoxins (B) are naturally occurring toxins produced by fungi, not a result of food processing.
- Scombrotoxin (D): A toxin produced by bacterial spoilage of fish, not a processing contaminant.
Step 3: Selecting the correct option. Since Nitrosamines are produced during food processing, the correct answer is (C) Nitrosamines.
