When it comes to leftover food, many of us have a “use it or lose it” mentality. We hate to waste good food, and we’re often tempted to eat leftovers even when they’re past their prime. However, eating spoiled or contaminated leftovers can be dangerous. Foodborne illnesses are a serious concern, and the Centers for Disease Control and Prevention (CDC) estimate that one in six Americans gets sick from contaminated food each year.
In this article, we’ll explore the leftover foods you should avoid eating, how to identify spoiled food, and tips for safe food storage and handling.
The High-Risk Leftovers
Some leftovers are more prone to spoilage than others. These high-risk foods can harbor harmful bacteria like Salmonella, E. coli, and Listeria, which can cause severe illness.
Dairy Products
Dairy products like milk, cream, and soft cheeses are breeding grounds for bacteria. They’re especially vulnerable to spoilage because they’re high in moisture and protein, making them an ideal environment for bacterial growth.
What to Avoid: If you’ve stored dairy products in the refrigerator for more than a few days, it’s best to err on the side of caution. Check for signs of spoilage like off odors, slimy texture, or mold growth. Don’t take the risk of consuming spoiled dairy products, as they can cause stomach cramps, diarrhea, and vomiting.
Eggs
Eggs are another high-risk food when it comes to leftovers. Even if they’re stored properly in the refrigerator, eggs can still be contaminated with Salmonella.
What to Avoid: Avoid eating eggs that are past their expiration date or have been stored at room temperature for more than two hours. Check for cracks in the shell, as bacteria can enter the egg through these openings. If you’re unsure whether an egg is still good, it’s better to be safe than sorry and discard it.
Poultry and Meat
Cooked poultry and meat can be breeding grounds for bacteria like Clostridium perfringens, which can cause food poisoning.
What to Avoid: Avoid eating cooked poultry or meat that’s been stored in the refrigerator for more than three to four days. Check for signs of spoilage like off odors, slimy texture, or mold growth. If you’re unsure whether the meat is still good, it’s best to discard it.
Fish and Seafood
Fish and seafood are highly perishable and can spoil quickly if not stored properly.
What to Avoid: Avoid eating fish or seafood that’s been stored in the refrigerator for more than a day or two. Check for signs of spoilage like off odors, slimy texture, or mold growth. If you’re unsure whether the fish is still good, it’s best to discard it.
Identifying Spoiled Food
So, how can you identify spoiled food? Here are some common signs to look out for:
- Off Odors: Spoiled food often has a strong, unpleasant odor. If your leftovers smell sour, bitter, or like ammonia, it’s best to discard them.
- Slime or Mold: Check for visible signs of mold or slime on the surface of the food. If you notice any mold or slime, it’s best to err on the side of caution and discard the food.
- Slimy or Soft Texture: Fresh food should have a firm texture. If your leftovers feel slimy or soft to the touch, it’s a sign of spoilage.
- Unusual Color: Fresh food should have a vibrant color. If your leftovers have an unusual color or have developed an unpleasant sheen, it’s best to discard them.
Tips for Safe Food Storage and Handling
To minimize the risk of foodborne illness, follow these safe food storage and handling tips:
Refrigeration
* Store leftovers in airtight, shallow containers to prevent moisture from accumulating.
* Label leftovers with the date they were cooked and store them in the refrigerator at a temperature of 40°F (4°C) or below.
