**5 Foods You Should Avoid Reheating or Keeping Overnight — According to Food Safety Experts**
Leftovers are a part of everyday life. But not all foods stay safe or nutritious once they’ve been stored or reheated. Some develop bacteria quickly, while others change in taste, texture, or nutritional structure.
Here are **five foods** that experts recommend **handling with extra care** to avoid foodborne illness and keep your meals safe.

### **1. Rice**
Rice may seem harmless, but cooked rice can **grow bacteria called *Bacillus cereus*** if left at room temperature for too long.
This bacteria produces toxins that **are not destroyed by reheating**.
**Safety tips:**
* Refrigerate rice **within 1 hour** of cooking.
* Reheat only once, until very hot.
* If rice smells strange or has a slimy texture, **throw it away**.
—
### **2. Potatoes**
Cooked potatoes can also grow *Clostridium botulinum* bacteria if left out too long — especially when wrapped in foil, which traps moisture and oxygen.
**Safety tips:**
* Cool potatoes quickly and refrigerate in a shallow container.
* Never leave cooked potatoes out for more than **2 hours**.
* Reheat thoroughly before eating.

### **3. Chicken**
Reheating chicken isn’t automatically unsafe — **the risk comes when it is not heated evenly**. Poultry is prone to harboring bacteria like *Salmonella* and *Campylobacter*.
Microwaves often warm chicken unevenly, leaving cold spots where bacteria survive.
**Safety tips:**
* Reheat chicken on the stove or oven, not just the microwave.
* Ensure the internal temperature reaches **165°F (74°C)**.
* Do not reheat more than once.

### **4. Eggs**
Scrambled, fried, or boiled eggs can develop harmful bacteria if left at room temperature too long. Reheating can also change the protein structure, making the texture rubbery and unpleasant.
**Safety tips:**
* Eat cooked eggs immediately.
* If saving eggs, refrigerate within **2 hours**.
* Reheat **gently**, or avoid reheating entirely when possible.
—
### **5. Leafy Greens (Like Spinach, Kale, or Lettuce)**
Leftover cooked greens are safe if cooled properly — but **avoid leaving them out warm**, which can encourage bacterial growth. Reheating multiple times can also reduce nutrients like Vitamin C and folate.
**Safety tips:**
* Refrigerate promptly.
* Reheat only once.
* Or enjoy cold — many leftover greens taste great in salads or wraps.

## **General Food Safety Rules to Remember**
| Rule | Why It Matters |
| —————————————— | ———————————- |
| Refrigerate leftovers within **1–2 hours** | Prevents bacterial growth |
| Store food in **shallow containers** | Cools faster and more evenly |
| Reheat food to **165°F (74°C)** | Kills harmful bacteria |
| Only reheat **once** | Reduces risk of bacterial survival |

## **The Bottom Line**
Reheating food isn’t dangerous when done correctly — the key is **proper cooling, storage, and thorough heating**. When in doubt, remember:
> **If the smell is off, the texture is strange, or your instincts say no — throw it out.**
> Food poisoning is never worth the risk.
