Many toxins in food cannot be destroyed by cooking or freezing.

• A. They can be destroyed by cooking or freezing.
• B. They cannot be destroyed by cooking or freezing.
• C. They are always destroyed by heat.
• D. They can be neutralized by washing with soap.

Answer: (B)

Many toxins in food are stable and survive heat and cold. Cooking aims to kill living microbes, but it may not destroy toxins already present, and freezing doesn’t reliably inactivate them either. Because toxins can persist after heating or freezing, you can’t assume contaminated food is safe just because it’s been cooked or frozen. Washing with soap won’t neutralize toxins that are already in the food. Preventing toxin formation through proper handling and storage is essential.
