Why can different coloured chopping boards be useful in an Indian food enterprise?

Correct answer: To keep raw, cooked and vegetable foods separate

The direct answer is option A: different coloured boards help keep raw, cooked and vegetable foods separate. A chopping board can carry food juices and microorganisms. If the same board is used for raw meat and ready-to-eat food without proper cleaning, harmful microbes may move from one food to another. This transfer is called cross-contamination. Colour coding gives workers a quick visual safety signal, although the exact colour scheme should follow the workplace or food-safety system. Option A is correct because separation reduces the chance of transferring contamination and also helps organise kitchen work. Option B is wrong because mixing all foods increases contamination risk rather than controlling it. Option C is wrong because the main purpose is food safety, not decoration or entertaining customers. Option D is absurd and unsafe: boards are not used to damage knives; proper boards should support safe cutting and protect equipment. Good hygiene also requires washing hands, cleaning boards, and using separate or thoroughly sanitised equipment. Memory cue: separate raw from ready-to-eat food; colour is a safety reminder, not merely a visual display.
