Lemons are a staple in many kitchens, used for their juice, zest, and flavor in a variety of dishes and beverages. However, like any other food item, lemons can pose health risks if not handled and stored properly. One common concern is whether old lemons can cause food poisoning. In this article, we will delve into the world of lemons, exploring their shelf life, the risks associated with consuming old lemons, and the precautions you can take to ensure your safety.
Introduction to Lemons and Their Shelf Life
Lemons are a type of citrus fruit that are widely available throughout the year. They are rich in vitamin C, flavonoids, and other nutrients that make them a healthy addition to a balanced diet. When it comes to the shelf life of lemons, it largely depends on how they are stored. Proper storage is key to extending the life of lemons and preventing spoilage.
