• C. Only important in hospitals
• D. True

Answer: (D)

Preventing contamination starts with controlling what enters the kitchen and how people handle food. Purchasing from proven trusted suppliers means the ingredients come from sources that follow safety standards, have proper documentation, and can be traced if something goes wrong. This reduces the chance that contaminated or adulterated items slip into food preparation in the first place.

Equally important is how every staff member handles food. Excellent personal hygiene—hand washing, clean clothing, proper glove or utensil use, and disciplined hygiene habits—stops pathogenic organisms from moving from hands to food, equipment, or surfaces. When hygiene is strong across the team, the likelihood of cross-contamination during processing, cooking, and serving drops significantly.

Together, verifying suppliers and maintaining top-notch personal hygiene address contamination at two critical points: the quality and safety of inputs, and the way food is handled by people. While other measures like cooking food to safe temperatures or sanitizing surfaces matter, they’re not as effective if contaminated ingredients are already in the process and if handling practices allow transfer to foods. That’s why these measures are considered best prevention practices.
