Late-night hunger can make almost anything in the refrigerator look appealing. Whether you’re looking for a quick snack after a long day or trying to avoid cooking, it’s tempting to grab whatever is available and call it a meal.
However, food safety experts consistently warn that some refrigerated foods can become risky when stored improperly or kept beyond their safe lifespan. In many cases, dangerous bacteria can grow without noticeably changing a food’s smell, taste, or appearance.
The good news is that a few simple guidelines can help reduce your risk of foodborne illness. Here are four common refrigerator foods you should think twice about eating if they’ve been stored incorrectly or kept too long.
1. Cooked Rice Left Out Overnight (or Stored Too Long)
Why It’s Risky
Many people assume rice is harmless because it was thoroughly cooked.
However, uncooked rice can contain spores of bacteria called Bacillus cereus. These spores can survive the cooking process.
If cooked rice sits at room temperature for extended periods, the bacteria may multiply and produce toxins that can cause:
- Nausea
- Vomiting
- Diarrhea
- Abdominal cramps
One important concern is that reheating does not reliably destroy these toxins.
