It is not recommended to store food in plastic bags for long periods of time. While some plastic bags are designed for food storage, prolonged storage can lead to potential health risks. Chemicals from the plastic may leach into the food, especially if the plastic is not food-grade or if it's exposed to heat. This can alter the taste and quality of the food and may pose a risk to your health. It's always best to use proper food storage containers or wrap and store food in a cool, dry place to maintain freshness and safety.
