What is a best practice to prevent contaminants in food?

• A. Purchase from trusted suppliers and maintain excellent personal hygiene.
• B. Use only household appliances.
• C. Only rely on cooking to kill bacteria.
• D. Ignore supplier verification if ingredients are fresh.

Answer: (A)

Preventing contaminants in food hinges on controlling what enters contact with ingredients and how those ingredients are handled. Sourcing from trusted suppliers who follow safety standards and provide traceability reduces the chance of contaminated or adulterated ingredients reaching your kitchen. Pair that with excellent personal hygiene during all stages of handling—handwashing, clean attire, proper glove use, and sanitizing surfaces—to prevent introducing pathogens and cross‑contamination. Cooking is important, but it isn’t a foolproof safeguard against all contaminants, especially toxins or spores, and it doesn’t fix contamination that occurs during preparation or sourcing. Relying on cooking alone or ignoring supplier verification doesn’t address these upstream risks.
