How can contamination of food be prevented?

• A. By purchasing food from approved suppliers
• B. By leaving food uncovered during storage
• C. By neglecting cleaning and disinfection
• D. By using unlabelled containers

Answer: (A)

Contamination is best prevented at the source by making sure food comes from approved suppliers. Approved suppliers are checked for safe handling, proper storage, temperature control, and traceability, so the products they provide are less likely to be contaminated as they move through the supply chain. This reduces the risk that unsafe ingredients enter your kitchen in the first place and helps you recall or manage any issues more easily if needed.

The other practices would raise risk: leaving food uncovered during storage invites dust, pests, and microbes to contaminate it; neglecting cleaning and disinfection allows bacteria to multiply on surfaces and equipment; using unlabelled containers makes it easy to misidentify items or mix different foods, increasing the chance of using spoiled or inappropriate ingredients.
