It is generally not recommended to consume crumbs or debris that have accumulated at the bottom of your toaster. These crumbs may have been exposed to moisture, dirt, and bacteria over time, which can lead to potential food safety risks.
Toasters are not airtight, and the crumbs can become a breeding ground for bacteria and mold. Additionally, they may have absorbed oils and other substances from the food items that were toasted, which can further degrade their quality and safety.
To be safe, it's best to avoid using the crumbs from the toaster trap in your soup. Instead, consider cleaning the toaster regularly to prevent the buildup of debris and ensure safe and hygienic use in the future. Most toasters have a removable crumb tray that can be easily cleaned to maintain good hygiene and toasting performance.
