Khaberni - If you are a fan of eating leftovers, like cold pizza or fried rice, it is important to be cautious about how long they are stored in the fridge to avoid the risk of food poisoning. According to microbiologist Dr. Primrose Freestone from the University of Leicester, some foods that may seem safe can pose a significant risk if not stored properly.
Pizza
Leftover pizza is one of the most surprisingly hazardous foods, not just because of the meats or cheeses, but also because of dried herbs and spices like basil, oregano, and pepper, which can carry bacteria such as salmonella and clostridium perfringens. Even if the pizza is well-cooked, leaving it at room temperature for more than two hours allows germs to grow rapidly. Therefore, it should be covered and refrigerated immediately, and it is advisable to eat it within two days.
Chicken
Cooked chicken is quick to spoil due to its high moisture content and low acidity, facilitating bacteria growth. It can be stored in the fridge for up to three days, but it is essential to ensure it is fully cooked and not to eat any part containing blood.
Rice
As for leftover rice dishes, whether plain, fried rice, risotto, or burrito, they may carry bacillus cereus bacteria. These bacteria may remain in the form of heat-resistant spores even after cooking, and if rice is left at room temperature for more than two hours, these spores can sprout and produce toxins that cause vomiting and diarrhea. To avoid this, rice should be cooled quickly after cooking and consumed within 24 hours, according to the "Daily Mail".
Canned Foods
As for acidic canned foods, like tomatoes, they can be stored for five to seven days if they are covered and refrigerated, while low-acidity foods such as meats, fish, fruits, vegetables, and pasta should be consumed within only three days.
Dr. Freestone summarizes that the key to avoiding food poisoning is to store leftovers quickly after cooking, cover them well, and adhere to safe time periods. By doing so, you can enjoy leftover meals without risking your health, making sure to consume them within a day or two at most.
