During the Lunar New Year, food poisoning cases often spike due to improper handling of leftovers. Bacteria multiply every 20 minutes within the "Danger Zone" (5°C to 60°C). To ensure safety, the Ministry of Health and nutritionists emphasize strict temperature control and the "reheat only once" rule.
1. Golden Rules for Storage: Leftovers should be cooled and stored within 2 hours. Refrigeration (<5°C) is limited to 2 days, especially for leafy greens, rice, and dairy/egg dishes. Freezing (<-18°C) can preserve cooked meats for up to 3 months. Always defrost in the fridge or under cold running water; never leave food to thaw at room temperature. Use airtight containers and follow the "cooked food above raw food" shelf organization.
2. When to Toss:
Seafood: Raw fish (Yee Sang) or steamed prawns spoil rapidly. Discard if refrigerated for over 24 hours.
Rice: High risk of Bacillus cereus (Fried Rice Syndrome). It should only be reheated once.
Signs of Spoilage: If food smells sour, feels slimy, shows mold, or bubbles, discard it immediately. Toxins from certain bacteria are heat-resistant and cannot be "cooked away."
3. Healthy Re-cooking Strategies: Nutritionists recommend the "Healthy Plate" proportions: 1/2 vegetables, 1/4 protein, and 1/4 carbohydrates. If leftovers are too oily or salty, rinse them with hot water to reduce sodium and fat before cooking.
Creative Recipes: Transform roasted meats into whole-grain wraps or fried rice by adding generous portions of fresh greens. Turn leftover soups into noodle bowls with added mushrooms and tofu.
Seasoning: Avoid adding extra salt or sugar. Instead, use natural aromatics like ginger, garlic, spring onions, or lemon juice to enhance flavor.
Bottom Line: When in doubt, throw it out. Do not risk your health to avoid waste; the medical cost far outweighs the price of the food. Label your containers with dates to prevent your fridge from becoming a "junkyard."
