What is the main risk of keeping leftover food open for a long time?
Answer and explanation
Correct answer: The risk of contamination and microbial growth increases
Leaving leftovers uncovered exposes them to dust, insects, hands, and microorganisms from the surrounding environment. If the food remains for a long time at an unsafe temperature, microorganisms may multiply and toxins may form. Covering food, cooling it promptly, refrigerating it safely, and reheating it properly help reduce foodborne-illness risk.
