Inedible items are substances that cannot be consumed safely or are not meant for eating. This category includes materials like plastic, metal, and certain types of plants that may be toxic. Inedible items can pose health risks if ingested, leading to poisoning or physical harm. Common examples of inedible items include household cleaners, medications, and certain mushrooms. It is important to distinguish between edible and inedible items to ensure safety, especially for children and pets who may accidentally consume harmful substances. Always check labels and guidelines to identify what is safe to eat.
